Removing the A64 IHS

[HARDCORECLOCKER]

:D Anyone tried a naked FX on single phase.......??? :confused:

:toast:

[Disposibleteen]

why on singel pahse why not some cascade action?

[sandybeach]

nice results :)

yeah you cant beat the TIM AMD uses between there chip and IHS :)
It gets all the tiny imperfections as its chalky/hard :)

Only put it back on in the first place for that other guy ;)

my winnie died for removing the ISH.

[cpulloverclock]

I remove that of my winnie in 1min with a cutter
very easy, +50MHz average stock cooling

I had to mod

Do You mean I'll damage the core or do You mean it will gimme a nice improvement?

:confused: Hm....., kind of strange here, just PMed to OPP and he told me he always removed the IHS from all of his chips.
And AFAIK he's using a cascade or promy all the time............

IHS= Intergrated Heat Sink

actually, it's Integrated Heat Spreader last i checked ;)

[ben805]

Who is the first one to stripped off those IHS on Venice or San Diego? have you noticed any improvement? common....I know someone is pretty extreme and hardcore enough to do it on their new cpu!! Please show some pictures when you do as well.... :D :D :D I'll take off mine as soon as I get my hands on it.

[$a1Ty]

yeah i want to see the die, so much purddier than heat spreader

[ozzimark]

i know it's not a real san diego, but the die size is the same (1mb)

Ummmm they dont look cooper to me!
In fact all the heat spreaders on all the A64s I have had are not cooper. :confused:

it is copper with nickle plated. just send it down and you'll see copper

mmmm purdy hehehe

if the ihs was soldered/welded to the core instead of just some TIM then it would actually work really well

[frostedflakes]

As far as I know transistor counts for the Venice are identical to Winchester, so as far as size goes, the 512kb dies shouldn't be any different. And ozzimark linked to some pics of the 1mb Turion dies, which should be the same size as the San Diegos.

[IvanAndreevich]

I intend to if I get one.

[GoodOmens]

How do you take it off? Is it easy to damage the chip if you do? I mean in the process of doing so.

[IvanAndreevich]

Check the sticky thread on it in Best of AMD

I cut the heatspreader off anything I get into my hands. :cool:
Don't like them.

Here are some pics of "naked" NewCastle/Winchester/Venice cores.

hey martin i have your 3500+ newcastle under my prommi atm.
i can't find the hs - for myself i had no problems when using "normal" cooling without hs but a selfmade prommi kit and a cpu without hs is no good.
it's running after 3 days of working, checking evap position, a little bit less sealstring...checking position, be carefull not to crack the die, scratched an edge, still running, but man this was the hardest i ever did since i started building computer systems.
still problems with over zero temps on =/>1.7V vcore....its hard to get enough contact on that small die without destroying it but with enough isolation on an standard mach I evap...the pipe to the evap turns as it wants so you always have a pressure against the best position - really nothing for cpu's without hs...

[cu2day]

That heat speader is hard to take off. I used a razorblade and worked at it for about 15minutes in and all still can't get the darn heat speader off. I ended up snapping the razor when trying to prey it off. Maybe more of you are more talented at the heat speader removal art form or I might be just too nervous compared to many of you. On the other hand I'm having to work at it with my chip in the socket still cause my chip doesn't want to come out. I have a good gap I cut in the one corner and cut the glue a bit along all sides but it wasn't enough yet.

Update, I've been trying to the the IHS off for about 40 minutes now still no luck. That thing is glued on pretty good.

Oh sorry I needed updated my sig. I have an AMD64 Winchester 3200+ CPU.

[NoStra]

i think thats a little optimistic, i havnt seen anyone achieve such drops yet, maybe 3 - 5*C at the most

With my old 3500+ Newcastle the temp dropped 10 ~11 degrees loaded. On my old winchester 3200+ it dropped 8~9 degrees. With the newcastle I gain 10~20 Mhz..with the winchester 70~80Mhz....

[psyshack]

Well I broke down and striped off the IHS. It just had to go.

It came off easy. Nice sharp razor blade and 2 mins. later it was naked. And to my horror there was no TIM contact with the cpu in the center. the center of the slug was bare. ( shakeing head )

Had to make up some shimes to remount the sink with good pressure, abit of as5 and we are back in the game. Add'ed another 45 mhz oc to it with the same 1.60 volts.

Its been folding for about 30 mins. and the temps have droped on the cpu by 6c. Was at 44c and now bouncing between 37c and 38c.

Ive been cycling the speed of the fan on the hyper 48. turn fan down to its lowist setting and saw 48c the first time. Then cranked it back up to high. Temp went down to 40c. Cycled it once more and now down to 38c. Room temp hasnt changed more than 2 tenths of a degree.

http://www.psyshack.com/a64naked.jpg

This move may very well pay off good.

[brandinb]

i riped the heatspreader of my sandiego 3700 and before mod my temps were 56c in prime 95 and it failed in 5 minutes and after temps are 42 and it passes prime all night long. this is at 9x300 with 1.65 volts. i think my heatspreader had bad contact or something because i didnt expect that improvement!!! im using a dfi and watercooling btw

[TEDY]

I'm gonna try to remove HS this weekend...What have to do ?
Careful for what ? I have DFI NF4 and 7000B-AlCU.

[justwOo]

As soon as i get some zerex for my watercooling im gonna install it and do the IHS at the same :D
Right now I can do 295x9 1:1 real stable at 1.6v but anything over that gets alittle unstable

[cu2day]

First time I took my heat sync off my cpu, my cpu came out of the socket with my heat sync. Of course I put my cpu back in and put the heat sync back on to find my cpu is stuck in the darn socket... this is a new 939 motherboard, if I can't get my current working CPU out in the future I guess I'll need a new motherboard to ever run a dual core cpu. Also I've been trying to get my IHS off but it's pretty hard to do when my cpu is stuck to the board and there's not enough room around the socket to work a razor blade around the edges of the IHS to get it off.

[psyshack]

I would be getting the cpu out of the socket before any razor action. Then look over you shiming options and how you going to get the hs back on.

Its not uncommon for a cpu to come out with the hs. I dont like it. but with a IHS and proper TIM application it happens

A cpu stuck in the socket,, now thats strange.

[Ref]

I removed my IHS.
Was i getting a good contact between CPU and IHS?
What is the best thermal paste to use? I used the one that came with my Zalman CNPS7000B. Is this a good one?

[cu2day]

Well I got the CPU out of the socket and got the IHS off but my temps went up. I guess I just can't win... should of left mine on in my case. I put the ISH back on top of the CPU but temps are always higher with the retail or the Hyper6 I have.

Update, I shaved down a bit of the rubber left on the IHS and my temps are slightly better than they were in the first place. It looks like I need my IHS on to get the best temps but I added artic silver 3 between the core and the IHS.

my load temp is only about 1-2C lower but that is at standard voltage... well test higher voltage after. But with a load temp of 40C after running prime95 for about 10 minutes isn't bad using air cooling

[Ref]

The problem is my OC lowered :(
Can this be because of not enough pressure on the core?
Please look at the picture in my previous post and tell me what do you think about contact :confused:

[cu2day]

My overclocked lowered as well but I believe this is because the heat sync isn't making full proper contact and my temps went up. I had to put the IHS back on in order to get proper cooling but I had to level up the bottom of the IHS but evening the rubber first in order to get good cooling once again.

I can't believe how heat sensitive these .09um process cores are when it comes to overclocking.

[Ref]

I have 0.13 um core.
So you just put the IHS on the core with some thermal paste on the core? and then mounted the heatsink?
And you got better OC than before you removed the IHS ? :cool:

Yep you got it. I can now overclock on average per voltage/clock ratio about 50Mhz more. I was hoping I wouldn't need the IHS but the core is so small that the slightest weight shift from direct center makes a big difference in the temperature department. if I run about 5C hotter my overclock drops by about 70Mhz. I need actual R134 cooling, than I'll see some nice gains with how much the smallest temperture changes affect overclocking.

[Ref]

How exactly did you put the IHS back?
is it worth it to buy some better thermal paste? e.g. Arctic Cooling MX-1 ?

[cu2day]

I never heard of that thermal paste. I know of Artic silver 1 through 5. 5 being the best of them all. Getting the best thermal paste is always a good investment if you like your equipment to run the coolest possible.

I only placed the IHS back on the center of the CPU no glue or anything with the case flat to the floor. My backet is a custom one that comes with my Coolermaster Hyper6 which allows very little side to side movement so their is little risk of moving the IHS out of place.

[CD 1986]

I thought i'd try removing the IHS, just for fun to see if i could get a better overclock and hit 2.6Ghz with my 3000+ Winchester...it didn't work. Not only that, i have a dead chip now! :( Lucky i'm gonna upgrade to Venice anyway, but it means having to go for the 3200 instead of the 3500 / 3700, so that i actually have a working PC!!!

Plus it's a bank holiday here in the UK; so unless PC world happen to have a venice lying around tomorrow, it'll be middle / end of next week until i can get hold of a chip! But if it's a good OCer i'll forget my recent mishaps. ;)

Will not be removing another IHS in a hurry! :slapass:

it isnt like it provides that much better of temps anyway

[ozzimark]

it dropped load temps ~8c on my clawhammer. that's decent imo ;)

[totensiebush]

it dropped load temps ~8c on my clawhammer. that's decent imo ;)
was it making decent contact with the core?
i suppose that if it really drops load temps by that much, i may have to remove it from my NC, although i might want to epoxy the thinnest piece of flat copper i can find on top to protect from chipping...

[ozzimark]

it wasn't too bad. the actual removal of the IHS was around 6c, then i lapped the core cause it was rounded a bit, another 2c or so off.

though, i highly advise against lapping cores. it's not safe unless you don't care anyway :slap:

[brandinb]

it isnt like it provides that much better of temps anyway

well i took the ihs off my 3700 diego core and droped 14 degrees celcius under load and gained prime stable from 2550 to 2725 and lost 14 degrees in between gaining 175 mhz more prime stable oc so yes for some it is worth it.

this is how i look at it if your using a copper base heatsink or watercooling and youre temps are high anyways it is probably because the contact is bad and you will get good improvements

if you using aluminum base heatsink and your temps is good then you have good contact and temps get worse going from copper spreader to aluminum on your heatsink

if you are using a copper waterblock for water cooling i can guarantee its worth it in any case as you will loose atleast 5-10 c and gain more oc and in my case loose 14c and gain huge oc increase of 175mhz so if on watercooling and getting 45c+ temps then do it but if your load temps are less then 40 then there is no gain to be had as my temps under load 1.725 volts went from 56c and fail prime in 5 minutes to 42c and pass prime all night long

It depends on your cooler. With my 7700CU, I could easily remove the IHS and just put a piece of metal as thick as or
thicker than the IHS under the retention clip on the inside of the heatsink where it pushes upon for tension to compensate.

If it always worked absolutely perfectly it'd just be the way candycan :D
Atleast yours is still ok

So you're running with a stripped venice + 7700Cu?
I'm seriously considering this because of my temps, much higher than my winnie (8-10C higher @ same speed and voltage), but seeing how people are afraid to break NC cores with water blocks, what do you think I am with this tiny tiny core? :slapass:

[cadaveca]

listen, take off the IHS, slap some AS5 in there, and put the IHS back on...makes for a better mount anyway...and just make sure that you cover the complete top of the IHS...it will all turn out good that way. 2600+ sempy @ 1.775v running FAH 100% load....41c w/ thermaltake beetle.... :fact:

I think it is very tempting to remove IHS for all these people reading this thread :) It is really not hard to do, but remember there is always risk of damaging your chip or not gaining anything ... however I still think it is worth it ... IHS makes a nice keychain :D :woot:

remember do not poke the razor blade too deep - 0.5 cm is enough. ;)

Still thinking about it... ;)
Two more questions, tho:

1) What happens if you try to start the computer without a heatsink (i.e. without contact), just in case it happens? I've heard that A64's should be able to handle this and simply shut down in time, will they?

2) Is it easy to get the IHS back on? Again, see above question, what if the contact between core and IHS isn't good enough? :(

Bah, didn't work out too great. Removing it went great, but I couldn't get the heatsink to sit stable at all... Even when I screwed it as hard as possible (well, almost) it wiggled back and forth *way* too much for me to even try it. I glued the IHS back on and put som AS5 in there tho.

What The?!?! I made a new post and it's now gone? What gives?

Anyways, I bought an XP-90 heat sync and with the IHS off with artic silver 5 thermal paste I get a load temp of only 35C at room temp of about 20C with my alpha6 the best I could ever get was about 42C under load. I can now overclock 80Mhz more as my max and with default voltage I can clock 50Mhz higher. Not bad for what was an already low temp. To test how stable this was I used super PI with 8M digits.

[twilius_basic]

Anyways, I bought an XP-90 heat sync and with the IHS off ...

I have an XP-90C, but I'm worried about mounting it onto a bare core. When mounting, the clip-method does not apply pressure evenly, same when removing the hsf.

Did you do anything special for mounting?

[Borgschulze]

Ok, had to get a new heatsink as my stock one the retention clip broke.
Using a Zalman 7000-AlCu.
Before. With IHS.
Room Temp. 20C or a bit less.
Idle 45c
Load 55c
Now. No IHS.
Room Temp. 30c or so..
Idle 39c
Load 55c

[frostedflakes]

For any small core (Newcastle/Venice/San Diego), I would recommend using a soft support of some kind on each corner of the processor. The foam pads from an Athlon K7 work well. You can use a razor blade to scrape them off, and then a very small amount of superglue to attach them to the A64. If you ever need to remove them, use a drop or two of acetone on the pads and then scrape them off like you did before with a razor blade. Use acetone and a Q-tip or razorblade to remove any remaining glue residue.

I wouldn't worry about this with a Clawhammer, as the die is practically the size of the IHS...

Here's a pic of my Turion64 with the pads installed. Every since I chipped the core of an old 2800+ Newcastle, I've been extra careful with my A64s. :stick:

[cu2day]

My old heat sync was the Cooler Master Hyper6, it was too heavy and tall to cool my bare CPU core without the IHS. I have the XP90 non copper, and use nothing at all to hold the heat sync tighter. If I'd of got the copper version it would most likely be too heavy again for go without the IHS. I manage to top out at 38C after hours of load at a room temp of about 22C at 1.475volts from 2Ghz to 2.3Ghz and that is with my fans set to low speed though I am using a 120mm fan on my xp90 which works well with low RPM cooling 1800 RPM to be exact.

Posted this in the sandy discussion thread, (due to a discussion about sandy temps) but will do it here too, because this is really were it belongs. Here's a nice pic of the core and the spreader too, hehe. :)

I just did a bit of surgery, dropped my idle temps from 42c to 32c literally. Also, I guess I answered my own question, heh, what was on that spreader? Plastic gooey shin etsu, same stuff amd has been coating stock HS's with for yrs, NOT good, 1 layer of plastic + 1 layer of copper + 1 more layer of plastic (for those who are too afraid to use anything else) + a stock HS = crap for temps. I imagine I would have been at about 45c idle if I did have that 2nd layer of junk. So glad I took it off. The core is small, heh. fyi, I had to sand down my dfi HS bracket all the way except for 1/10 of a centimeter. I ran a 8 min super pi just to see how high the temps would spike, they didn't go past 42c. 10c must be pretty consistent for a temp spike seeing as how everyone else is getting about a 10c spike, 3 gigs, here I come, heh.

finally remove the IHS of my crap venice... only 2.75Ghz on 1.68v..

I don't want to lap it since also void warranty so took the heart out to remove it....

load temp reduce by 11 degree celcius and now at 41 on load...

Hopefully someone can help. I had a 3500+ I sliced and cut into the board (Didn't realize it lapped the IHS and reapplied causing it to short). I killed my 4000+ sliced it and all went well. At first. Used nail polish to cover the chips around the core since I wanted to use DI eventually. Put on my waterblock and was careful. Booted for a sec. and died. I found one of the chips arced against the H2O block. Saw the burn on both. Now I am really considering doing it on my FX but what should I use to keep it from shorting. (I hate grease)

Make sure you hold the blade perfectly parallel with the chip.
And do not go in any more than a half centimeter,
Start at the corner and then slide the whole blade under the side no more than a half centimeter, you can feel when you hit one of the little chips that are on top of the organic material.
Just be more careful this time if you do decide to do it.

[alexio]

What are the exact dimensions of the San Diego core ? (in milimeters please)

Just like to know because I'll be making a waterblock for that chip soon :cool:

[Borgschulze]

64 mm2 I believe.

[harleybro]

Well I've got the cutting part right but what I am confused about is why my chip may have shorted against the waterblock. :confused:

[justwOo]

just put a strip of white tiny white foam you get with some hardware on all sides of the cpu, that'll help stop your waterblock/hs from rocking and shorting out
btw.. nice shim electroid!

64mm is too big thats bigger then a stock cpu fan!! it looks like 15mmx12mm or something from peeking over at my shim i poped off and looking at the footprint

Anybody know anyone else who took off the IHS from their Sempron?

[wevsspot]

I can attest that removing the IHS on the Venice core will increase your O/C ability and reduce temps, especially under load. I've been stuck forever at 2.565ghz on my AMD63 3000 Venice. I just couldn't give it enough juice and keep the temps. where I was comfortable. Removed the IHS and boom! Was able to use 1.52v and get my Venice to 2.610 Prime and MemTest Stable. Now, this isn't for the faint of heart. I've got a ThermalRight XP90 with a 90mm silent cat on top. I used lighter fluid to "soften" the glue that holds the IHS on the Venice core. Then I proceeded to gently use a razorblade to cut through the adhesive. Up to that point everything was looking great. But then I found that due to the HS bracket on a MSI K8N Neo 2 motherboard that my XP90 wouldn't clear the CPU hinge brackets on the motherboard. So off to the bench grinder I go! Well, 2 hours later I had removed enough material for the HSF to clear the CPU socket on the MSI m/b. Used some AS5 (just a dab) and installed my "modified" heat sink and fan. Max temp. under load running F@H and Prime95 Torture Test is 48C. Used to be 56C at lower voltages and CPU speed. This has got to be one of the best mods I've ever attempted!

[kite7]

Would it be worth it if I took off the IHS, put AS5 on it and put the IHSback on?

[THunDA]

Would it be worth it if I took off the IHS, put AS5 on it and put the IHSback on?


It might help "a little" but not nearly as good as no IHS..

Personally, I wouldnt void my warranty just to put AS5 on the core..

[wevsspot]

I agree 100% with THUNDA. Once that IHS is off, leave it off. I see you've got a Venice 3000, so we're not talking about a $800 processor. If you do remove it, I can almost guarantee that the AMD64 overclocking gate will disappear! I was very impressed with the weight, thermal paste and thickness of the IHS when I removed it, but there is no question that direct contact between your core and your selected HSF works better than the interference caused by the AMD IHS. Honestly (and I said it in my original post) this was the best two hours I've ever spent modifying hardware. Even considering the problem I ran into with my XP90 heatsink.

[PoL]

At last, I took it off. :D
I won't be able to try it till august, but doesn't matter, I hope it'll help to get better temps.

Any tips to take into account? :)

I'm want tho remove my IHS to from my 3000+ that does 2800-2900 on air.
Isn't this tricky with a XP120 cooler??
I want to see more pics please.

Better use the paths on the corners?
Or mod the bracket???

[Ugly n Grey]

I am so tempted to try it with my x2 but I don't dare. They are just too much bread. Having said that I will try with my Venny 3000+ for the competition. I was thinking I'd remove the IHS and then mill down the outside edge and remove the center until it was flush with the core. So imagine the IHS with the core poking out a hole and everything nice and level. Might help the crush factor.

[douirc]

i've been working on this for about 2 hours now and the frustration is kicking in. i can't find anything thin enough to fit under the IHS to crape away the black sealant. i've tried a box cutter blade and the smallest precision screw driver I have, and both are too thick. any suggestions?

I had that same f*cking problem, I almost went crazy...
Everything was thicker than the tiny space between the IHS and the chip...
Until I got this... It's even thinner that the space, perfect!

Get an old fashioned razor blade for shaving from thr drug store, they are so thin they flex like nuts, cut it down the center in half. Now cut a groove into a toothbrush handle and epoxy it inside so that only about 3/4 of a cm is exposed. it will become rigid and is ultra thin and obviously, razor sharp.

[PoL]

I think there's no need to do that. If you're careful and hold it by the middle, it's completely safe. You don't need to quick, and it can even become fun... :D

awesome! that's exactly what i was looking for...a pic! will my rite aid next door carry these?

[Ugly n Grey]

Rite Aid = more than likely, I only posted because I have used this method before, I found exacto knives would break, where these things are really flexible and you can glue them so that they don't stick out very far and you don't risk damaging the little brown things that surround the CPU.

Thanks for the piccy Sai

[douirc]

wow! thanks for the awesome suggestion. i picked up a pack of 10 from CVS on my way home from class for $3.99...best money ever spent! took about 12 mins flat to run the razor around the edges and "pop the top". piece of cake. word to the wise...although creating a means of holding the razor is overkill, i would highly suggest breaking off one of the sharp edges on the double-edged razor. i've definately been wounded (still bleeding). take a look at the pic. btw...i was shocked to see how light the thing is with the top off! 85% of the processor weight is that top alone!

now on to my second question...putting the HSF on! I have a jumbo TT Big Typhoon and i DON'T want to crush the core! what's the best approach for mounting this thing without all the risk of a dead proc?

[xs64]

I wonder that is anyone here can mount the XP-120 with the non-IHS Core ??

[Ugly n Grey]

Glad it worked out douirc , sorry about the damage, the reason for the custom holder is that with a single slip you can lose a good chunk of a finger (I'm serious about this).

Anyhow, I have done this a few times and I've used shims every time. I made some out of very thick cardboard that worked well, the problem is it takes a bit of trial and error to get the correct thickness for good contact, I always start too thick. Someone else suggested using the pads from an XP series proc and gluing them on. Never tried that myself. I also have shims from water cooling kits that I have used and there's even more information on all this in this very thread. I think the same methods work regardless of the type of cooler, I have mounted a 7700 Zalman copper on a Winnie, so there you go :)

Oh yeah thanks for the piccys of the final top off result :toast:

[JLS1983]

I wonder that is anyone here can mount the XP-120 with the non-IHS Core ??

Yeah, I've been using my XP-120 with no IHS on my 3200+ Winnie for a while now. I took some of the little black pads off of another CPU I had and used a tiny amount of super glue to attach them to the naked Winnie. I didn't make any modifications to the retaining bracket either.

EDIT - Guess it's my first post, but I've been reading the forums for a while now.

Is it safe to remove IHS and put XP90 on it ?

Or should i leave 7000B-alcu ?

[Ugly n Grey]

modding a chip is not safe it's xtreme and it is a litle risky but not if your're careful, read the thread.

LOL Urban :toast:

[douirc]

I created a little shim using the foam from the packaging the TT-BT came in. the intention was for the foam to compress as the HSF was torqued down to relieve some of the stress and weight off the core. one thing i learned in the aftermath, first put the HSF down on the bare core and measure where it sits, then put the shim on and crank it down until it reaches the point where you marked. after i put the shim on i couldn't see the core, and didn't know how far to torque down the HSF.

Anyway, temps are down between 7-9C on full load and i'm prime stable at 2900 1.648V for 4 hours now. I'll keep tweaking and update later...

[PoL]

That seems to be a great idea. I'll try it.
But can you explain better what you did? Cuz I didn't really get it... :P

Thanks!

[orig3n]

Nice work mate, good results. Be sure to use nail polish remove or alcohol when doing this guys, it will make your job alot easier as it eats through the glue and the blade will slide right under it.

I like the shim idea, i have foam now so i just lay that around the core, its always a very good idea to do a test mount and make sure you get a imprint of the CPU core on the cooler to ensure contact. :toast:

[p0tempkin]

orig3n, are you talking about isopropyl alcohol, or acetone?

very good point! I should have mentioned that too. after i layed the foam shim down, i put a small dab of AS5 on the proc, then laid the HS down on the shim and pressed down with my fingers. after releasing, there was AS5 on the bottom of the HS, ensuring the two plates were making contact.

PoL - the basic principal is to relieve the HS weight off the core. you could put your HS directly onto the core, but you risk crushing it. all i simply did was take the foam that came in the packaging with my HSF, cut it into 4 strips and lay the strips around the core. if i rest the HS on top of the foam shim, the HS and core don't make contact. this is a good thing, because when you start to tighten down the HS, the foam will support the weight and act as a buffer. all you need to do then is tighten just enough so the HS and core make contact. you'll know when they make contact if you take measurements off the bolt (or some point of reference) with the HS resting directly on the core. A perfect example of this is AMD's Barton chips. they create a shim using rubber pads on the four corners of the PCB. I'm simply trying to recreate this with stuff lying around the house.

i hope that helps. i don't think i can be any more descriptive. trial by error is always a good method of learning too, so give it a shot!

[PoL]

orig3n, are you talking about isopropyl alcohol, or acetone?

I think he means both. :)

[Ugly n Grey]

acetone is the active ingredient in nail polish remover; I would suggest he meant isopropyl alcohol as vodka is not something to waste on a CPU :)

Thanks man. It really helped, I get what you mean now.
OK, so a good point would be tighten down the HS and then take it out to check if the contact was perfect, right?
And what about an evaporator? Can I use this foam method?

thanks!

[Crazykooter]

Well looks like I was one of the unlucky ones because I just removed my IHS and I have lost speed. Not sure what is up with that but my temps are down 2c which good but I dont truely understand how I would lose mhz. Oh well guess I should throw it back on and see if I can get my mhz back up. I will give it a set in period 1st tho just to make sure. Do yall remove the black ring once the IHS is removed ? I had to tighten down pretty hard to get contact. I think its a good thing to have it there to keep me from crushing my core so I will just leave it for now. :stick:

[NickS]

I've been thinking about doing this to my Newcie 3000+. Do you think I would need a shim with my XP-90 (Regular)?

I really don't wanna stick something flammable (ex Cardboard) or meltable (ex foam) next to my core---as newcie's run REALLY WARM. Arent the newcastle cores VERY large anyway?

I use a brand called nu-doh. You cut off a piece of the putty stick, then knead it into a ball to mix the 2 parts.

Put 4 small balls on the corners of your a64 and squash them down to the required height with your heatsink.

No mess.

[Ugly n Grey]

Carboard isn't flamable at the temps a mobo or cpu works on. By the time that carboard lights on fire your board woould have fried.

Lith1um has a great idea, but I've never been that patient personally, there's lots of stuff out there and lots of stuff in this thread to choose from.

Have fun

[Lith1um]

Well, the putty hardens completely in 5 minutes.

It is a solid, leaving no clean up. Your hands are barely even dirty.

All you do is take a knife, cut off a 3/4 inch piece of the stick. Knead it for 10-15 seconds, and use it before it hardens.

You could make a squished ball on each corner, or roll a thing string out on your desk and shim the entire perimeter of the chip in a matter of seconds.

[Ugly n Grey]

I know the product, I use it to seal leaks in water pipes temporarily and the like (works on gas tanks too). I think it's a great idea and hell I'm going to try it, but most folks won't have that in their drawer at home ,mine is at the cottage :) and I don't have the patience to wait till I buy more or bring back the stuff I already have is all I meant. Thanks for the tip truly- it's going in the mod book for sure!

would doing the IHS removal and using my current SLK948U be ok?

[Joe Camel]

ive been wanting to do this for a long time, but never had the balz to do it.... till now.
with a 2x sided blade, it was CAKE!!

3500 Venice:

http://img333.echo.cx/img333/470/pict02572qg.jpg


its *really* easy...the blade is SOOO THIN, it literally slides under the IHS
(in the gap of the "glue" on the one side) and then its sorta like cutting
Tygon tube with a dull blade...sorta

you need to put some force behind it and try to keep the blade FLAT to the
CPU PCB (you *can* shave into it if your sloppy!)

i taped off the blade for my protection and to "mark" about how deep
i thought i should/could go...probly went too thin the first few cuts,
i ended up going around 3+ times

after that it lifted right off



im blow'n away just how thick this thing is!! (.094")

HERE (http://www.ocforums.com/showthread.php?t=399740&page=1) is the link to my thread over on OC :fact:

seems to have dropped my temps 4C...and got me to 3GHz :hrhr:

[amrgb]

First of all I wanna thank the quality info posted in this thread that helped in my IHS removal :toast:

Now, just a few thoughts about my experience (winchester + XP120 + DFI NF4)

1. I've cut through the rubber with a double edged razorblade without issues. My blade was similar to the one posted by Sai

http://www.seilnacht.com/Lexikon/rasier.JPG

It's safe to put the blade inside until the letters "dreifach..." disappear. It's not necessary to go any deeper and the blase will be far away from those small things around the corner.

2. Unlike many have stated, there was no need to sand off the socket near the lever, since the core was in a higher position. :)

3. It's necessary to sand off the base of the XP120 mounting bracket by the height of the IHS (or a bit less if you want to decrease the pressure on the core). First because if you don't do it, the heatsink will touch in the bracket and there is not enough contact with the core. Second, to readjust the pressure on the core, which decreases because the core will be on a lower position (although you may not want to have so may pressure as originally)

4. It was necessary to bend (not much) a heatpipe (the leftmost when seeing the heatsink with the heatpipes in the bottom) because it touched in a mosfet's heatsink and prevented a good contact with the core.

5. It is highly advisable to unscrew the bolts that fix the springs to the heatsink. In this way is possible to fix the springs with the heatsink base almost in its final position, on top of the core. Later you can screw the bolts again. See the pics posted by Ubermann here: http://www.xtremesystems.org/forums/showthread.php?p=864930#post864930

Even though, I cracked a corner of my core, but it's running ok

6. I've not tested thoroughly, but atm I've gained 50~60Mhz on both Prime stable clocks and Superpi32M stable clocks (the later about 60mhz higher than the former). My temps went down by at least 6C (with fresh AS5)

[4rory]

Interesting, now do you think this is worth risking my +3200 lbble 0515 apaw? :D In my quest to get to 3ghz on air, 50% overclock :D I'm still at 1.55 volts but temps scare me.

[Charloz24]

Only you can answer to this question....is it your money after all :)

It will definately helps......but modding and overclocking is never 100% safe...

[amrgb]

Interesting, now do you think this is worth risking my +3200 lbble 0515 apaw? :D In my quest to get to 3ghz on air, 50% overclock :D I'm still at 1.55 volts but temps scare me.

Now that I've succeed, I'm glad that I had the guts to do it. In my modest opinion, if you follow carefully the information and tips given in this thread, the IHS removal is not difficult or (too) risky. The problem is to mount huge heatspreaders on top of small naked core.

Honestly, I decided to remove the IHS because I'm planning to buy a X2 until the end of the year (in the US since they are much cheaper than in Portugal). If this went wrong, the only bad thing was to anticipate the X2 purchase and pay more for it.

Also, the fact that my winchester is a bad overclocker would make its replacement easy. Almost any cheap 3000 Venice can do more than 2650.

To sum up, if I had a cpu doing near 3ghz on air, definitely I would not do it, unless I was getting rid of it.

[4rory]

I don't think it's a question of money I could easily buy another one, but I highly doubt it would do as good, Meh I don't think 50mhz is worth the risk, i'll pass for now.

[amrgb]

Exactly. Money is never the question, or else the answer would be pretty simple: DON'T do it.

The question is whether it is easy to replace the lost cpu if something goes wrong. In my case it would be near impossible (from what I've seen) to get a venice worse than this.

I removed my IHS which at 1st gave me trouble with less OC. But since then I fixed my raddy and reseated the TDX block. I am now able to get 2838 mhz with 1.52 volts stable where as I was having to use 1.65v.So very nice drop in vcore and gain in stability. Wasnt hard to remove either.

[kimandsally]

well.. i took mine off yesterday, and i must say, it was definatly worth the time, temperatures dropped DRAMATICALLY. may i note i have an xp120 w/ 90cfm pana.. you'd think it'd be "dangerous" to mount this heatsink on such a fragile core, plz.. mounted NO problem at all!! this is a 3000+ by the way. heres the results

heatspreader on w/ stock : 32/41c
then heatspreader ON w/ XP120 : 28/35c
THEN heatspreader OFF w/ XP120 : 21/27c !!! woo :D

Wow they're great results what's the ambient temps?

[adslegend]

I'm :banana::banana::banana::banana: out of luck with A64 recently :(

Firstly I get probably the worst 3200+ Venice in history, maxed at 2.6 GHz / 1.7V / water :eek:

Then I bust the IHS off my San Diego, see zero reduction in temps and 0 increase in overclock. Ah well :rolleyes:

[ElDuderino]

I am having a hard time tryin to decide if I should remove the IHS off my X2 4800. My TEC only brings it down below freezing during idle if the fans are on full blast on the rad.
Is everyone seeing 50-100mhz or better on their overclocks after removing the IHS?
I am wondering if it would help my second core OC better since it errors out of Prime95 alot faster than the other core.

[adslegend]

Well maybe I spoke a little too soon, it hasn't affected my temps as reported in MBM5 at all but then I think this board can't report temps correctly as I get exactly the same idle/load stock or overclocked :rolleyes:

My waterblock temperature seems to have decreased a few C under load, and although my prime stability is still maxed around 2.75 GHz I can do everything else like Fold/game at higher clocks now, guess it shows what a POS prime95 is really.

[babalouj]

has anyone tried the dental floss method of ihs removal?

[njkid32]

has anyone tried the dental floss method of ihs removal?

I have and it didnt work. The floss isnt strong enough. I just used some take to block the razor from going to deep. I wanted to make sure that I didnt hit one of those ic's.

[iboomalot]

can you put the IHS back on to keep from voiding your warrenty???

or once removed all warrenty is lost??

[Korpse]

just put ceramique on it when putting it back on, shud keep it on :confused:

anyhow, im using an SKL948U with my naked A64, can i use a XP90C? i really wanna get one :p: but if i cant use it with my naked chip i wont.

cos i got some money now to finish off my air cooling after giving away fans with sold components, and im going for gold with my cpu air cooling with a naked chip,XP90C and a 92mm Tornado :)


cheers

[4rory]

I wont recommend the xp-90 on a naked chip, I have it and its pretty hard to get it clipped on, I end up bending like all kinds of fins with the screw driver. But maybe if you put some of those stick protection tabs uses to protect things from bumpins. Kinda like the old amd chips had on the corner.

I got the 92mm Tornado also, it's loud and annoying, and at half speed and full speed there isn't even a 1c difference, so get something else.

[Korpse]

Tornado ordered, XP90c isnt and wont be :p:

gotta try the tornado out myself on full blast as i didnt get a controller :D rawk!

[Chuck232]

Got rid of the IHS on my nearly year old A64 3000 NC. Also switched from a XP-90 to a TT Big Typhoon. Had some intial qualms about TT stuff, as I haven't come upon a good TT heatsink in the past. But this one's pretty solid as far as I can tell. At stock temps dropped from 29C idle/41C load to 25C idle/34C load. I'm doing some overclocked testing right now but I can say I ran prime for about 20 mins with no problem at 2.5GHz whereas I couldn't even do 1 mins stable at anything past 2.4GHz before. Didn't have time to run for more than that for the time being, but I'll be doing more testing later on. Very beneficial overall though. Sliced up my finger a couple times though. :p

[ChongL]

Mine idles at like 40C and loads at 52-53C

I have the EXACT same setup at work...and it idles at 27-28C and loads at like 38C

Im gonna pop the IHS off the one at home when my waterblock and everything gets here

[babalouj]

does anyone know where to get the pads that are on athlon xps or replacements that would work? I dont have any old procs laying around to steal the pads from.

[4rory]

That tornado is gona be loud, I thought i could deal with it but its like a blow dryer at 3/4, can't hear yourself think.

[babalouj]

i just ended up buying this http://store.yahoo.com/directron/tn3535.html. now hopefully it will be thick enough.

[njkid32]

i just ended up buying this http://store.yahoo.com/directron/tn3535.html. now hopefully it will be thick enough.

I wonder if that thing is going to retain heat to the ic's and pcb cuz it only has a hole for the core. I also wonder if its ok to put that rubber thing directly ontop of the cpu. I'm sorry I wouldnt trust it. I does look like a good idea though!

[mbm]

Have been reading this thread now -It took a while.
I think I may have a nice NC 3400+.
It is only prime stable at 2700mhz (1,6V) but I cant boot up to 2820 (1,75V)
My temp when running prime95 hits 52-53C (it seems hot when reading this thread).
Maybe getting lower temps would make my OC go higher?
Im using a Zalman7700CU -it is a very big HSF, so I may be a bit worried.
Anyone tried it?

[Korpse]

That tornado is gona be loud, I thought i could deal with it but its like a blow dryer at 3/4, can't hear yourself think.

yup, ur right :( im not using this thing (tornado) for 24/7, ill use it for benchmarks and memory testing :)

[babalouj]

first of all, heat is drawn out from the the cpu core, theretically, nothing else should get hot. secondly im gonna phase change and it wont be any different than covering the cpu in dielectric grease. rubber is dielectric anyway so it wont hurt. Plus, I can cut out any patern I want from this rubber, I was just going to cut it to go on top of the black silicone from the ihs anyway.

[[XC] DragonOrta]

I'm going to try this with my week 21 3200 once I get out of the hospital. If I can get 2.8 at around 1.525-1.55, I would be more than happy. The best I can do so far is 2.73 at 1.55.

[mbm]

But how can I know it is the heat holding me back.
I cant get it stable over 2700mhz -Giving it more vcore doesnt help either.
Im running 1.6V now and it gets 52C at prime95.
I can boot at higher speed with higher vcores but it isnt stable. But it locks up even at 40C -So doesnt this tell me that it isnt the heat?

[Robin BP]

Mine 3700+ SD clocked to 2700 Mhz goes up to 50c load with Prime, and thats with only 1,5v. Even the water block feels cold. Wondring if i should take of the IHS or just leave it on. :rolleyes:

My old 2400+ Mobile was never over 47c with 2v clocked to 2700Mhz, so something tells me that the IHS isnt doing a god job here.

[Korpse]

Hey guys,
Thought some S754/Newcastle users might find this interesting:

3400 Newcastle @ 2.6GHZ with 1.61v

IHS+92mm YSTech 55-57c LOAD
no IHS+92mm YSTech 50-52c LOAD
no IHS - 12v 92mm Tornado 44c LOAD
no IHS - 7v 92mm Tornado 48c LOAD (what im using now)

so now my 24/7 temperature had dropped 7c :woot:

[mbm]

But are you getting higher OC?

Today I tried to remove the IHS, but I havent got a thin blade to get cut the IHS off.
The layer is only about 0.5mm thick.

Im not sure I can thighten the screews om my Heatsink any futher. If I get the IHS off -wouldnt that give me some gap between the core and heatsink then?

[Korpse]

i havent tried OCing more yet :p:, mainly co if its unstable and im folding it will mess my production up - im gunna try later tho :D

[Absolute_0]

OK i just removed my IHS, good move indeed
i also stole the pads from an old AXP to lessen chance of core crushage
So far load temps are down 5C and i can use way more volts without seeing temps take a hit, right now i'm finally stabilizing at 3 Ghz on my water setup, temps not exceeding 40C with 1.73 volts

http://img.photobucket.com/albums/v729/absolute035/overclocking/IHS-off.jpg

[mbm]

I would really like to know if my Zalman7700CU would make contact to the core after removing the HS?

[PoL]

The problem is that the plate of the MB doesn't let the heatsink touch the core... I had to mod the heatsink... :D

[Korpse]

hey guys

this has let me overclock stably 120mhz more over having the IHS on :woot:

currently at 2.72ghz D2OL stable (previous was 2.6ghz due to heat), think i hhave more left too :banana:

[mbm]

how did you mod the HS? Is it a Zalman7700CU?

[Korpse]

me?

my cooling is in my sig :) 53c load

[mbm]

No PoL #456

But yor didnt mod your HS to fit the core?

[Quest For Speed]

I reading this thread I decided to give it a try so off went the IHS. My Shin Etsu paste is still setting but so far my temps went down 2C and I gained 40 Mhz stable OC. It is not a huge improvement but hey, every little bit helps.

[XTPE]

It made me crazy .
Before my winni 3200+ reached 56C at 2450/1.42v so I also decided to give it a try but very worried .
IHS is finally off but with a little break at one corner of the PCB ( not the core ) .
Sanded off the 2 faces of the IHS , placed it on the CPU as original with very little glue at corners then re-installed everything . Damm , it still working but my temp jumped up to 58C at the same speed .
Crazyly , I decided to remove IHS again and put my XP 120 directly on it with no pad .
This decision satisfied me . It works much better . I'm now running 2600/1.54v , 34C idle , 43-44 at load , ambient 32C . Before I tried 2600/1.64v/60C/unstalble .
Really amazing , I gain 150 mhz and my temp is down by 16C .
My sig :
- DFI Lanparty UT nF4 SLI-D .
- XP 120 on nude Winni 3200+ 0444 RPAW @ 2600/1.54v .
- 1G Corsair 3200XL - X800XT .

[ChongL]

here are my results

before: 9x300=2.7GHz 1.55volts 53C Load/39 Idle on air
after: 9x312=2.8GHz 1.67volts 40C Load/30C Idle on water

[Quest For Speed]

Removing the IHS makes a huge difference with my X2 3800+ processor. I just got it yesterday and after mounting my waterblock the chip went 2.7 no problem 1.45v but my temps were 52C load. I remounted my block thinking that was the problem, same temp. So I removed the IHS and now I am burning in at 2.85 1.56v with temps 29c idle, 38 load. That is a big difference.

[VoRtAn_MaDgE]

Tried a second time now to remove the IHS.
Damn I cant do it.
I cant find a thin blade to get between the IHS and the cpu.
Yours must have been a thicker layer.
It just pisses me off.
Didt yours come off easily?

[Der_KHAN]

take a razor-blade and push it in. dont use it like a saw

[mbm]

But is only the cuttingedge that I can get in between the HS.
The layer is so very thin -about 0,5mm -Is this normal?

[Der_KHAN]

yes

[mbm]

People are taking about this as an easy mod.
I would say it is a hard one.
How can you use a thicker blade than what the actually cap is between the HS -I just dont get it. If I push hard -it just give a metallic sound, because I then cut in the heatspreader it self.

Removed the IHS, take your time for that,
a few tips:
(1) Processor pins are fragile, set it in foam.
(2) Use breath-thin razor-blades.
(3) Always work on the top margin of the black silicone.
(4) No saw or cut, very gentle pressing in been sufficient completely. Piece for piece around.
(5) Subsequently, where the gap is in the silicone and the black plastic sign, puts a fine screwdriver on, Up-lever and then again very slowly.

Finaly you are lost from AMD (greenhouse) CASE temp.

Clean the processor core carefully with 99% alcohol.

Now maybe you need to mod your CPU Heatsink, so it make a properly contact with the core!

Use Arctic Silver AS5 ......

I used a hobby knife which is pretty thick, but I took my time and didn't try to get it of at once, I had to go around the IHS twice.

Using Alphacool Nexxos waterblock and 3x120mm radiator, with IHS idle 39C - load 50C, without IHS idle 34C - load 40C. :clap:

With the IHS on, as soon as I started Prime95, temp would go up to 49-50C and drop down instantly to 39C as soon as I stopped it. With the IHS off the temp doesn't jump around like that anymore, ramps up and down more progressively.

Glad I went to the busy shopping mall just to get razorblades :D

Not sure how many have actually takin the IHS off then put it back on but my temps were good with it off but I had issues with the TXD block touching the resistors on the cpu so I put the IHS back up with some as5 between the core and ihs. TO say the least the temps are now the same as if I had the IHS off. So its not a matter of taking it off and leaving it as it is just getting better contact between the core and the ihs. I had lost some oc with ihs and now I am back to normal oc + 20mhz. Go figure.

[Crazykooter]

How did you know it was making contact with the resistors on the cpu? Did it short or something?
When I removed the TDX and looked at bottom of the block I could see where the resistors where touching the block. Made nice little marks. Really made we wonder if others are doing the same thing and not aware of it. Not sure if it would hurt anything as long as the resistors arent being crushed but I couldnt take that chance. In the end I lost nothing by putting IHS back on. Like I said before I gained my OC back with IHS on.

[eclypse]

Yeah i have the same probs right now.. That and also the block not making perfect flat contact with the die.. I put small stipes of black tape over them just encase they did touch so it would'nt short out if it could.

I dont see why even putting the IHS back would help that.. Those chips will still touch that as well.. THe only reason why it didnt touch before is the thick goop they used.

[cischico]

OK here are my finding thus far. Previously on air using an XP-120 my max stable overclock was 2650 at 1.6V. I then got watercooling and my max stable clock settings was 2700 at 1.56V. Very small improvement after dishing out $500 bones. Now that I finally removed my IHS which took me two tries on two separate days I have noticed my temps only dropped 2-3C LOAD and IDLE 1-2C. Not much of an improvement; however, I did noticed that dual priming (with affinty set to each core) no longer results in an instant temperature increase. Before the IHS was removed my temps went to 38C instantly. I mean the moment I thought about hitting that "OK" button my temps were at 38C. With the IHS removed I actually saw a gradual increase from 27C->31C->35C and from 35C it fluctuates a lot with the max being 37C. Ambient room temperature is 23C. I am currently dual priming and dual super pi at 2800Mhz at 1.55v. Before the IHS this was instant fail, so far so good at 45 minutes. I have to say this was completely worth it. I'm almost certain that the IHS was getting a majority of the core, but not all of it. There must of been a "heat pocket" that was causing instability. I can't believe im actually priming at 2800Mhz at this voltage. This has been an instant failure everytime no matter what voltage I fed it. (upwards of 1.65v)

I highly reccommend this mod!

:woot:

[shimmishim]

it was a nice mod.

it dropped my load temps from 50C's to 42C's.

only got 8C's load off my load and no gain in o/c yet.

temp drop is nice though, can't complain! :)

[Mr. Tinker]

I just wanted to check in on this thread with my experience.

I removed the ihs from my week 17 venice with ease, first try in about 7 minutes. I used an old-style shaving razor bought from Walgreens ($4 for 6 blades generic package). The razors bend very easily. I initially tried a hobby knife blade but it was too thick, even thicker was a box cutter blade.

After applying electrical tape to the blade all but 3mm from the edge, I gently inserted the blade intermittently along the sides, then once down each side I stuck the whole thing in. After each side was done I gently stuck the whole blade back under each side a pried just a bit at the corner using the leverage of the blade. After a few pries, it easily popped off.

The next step was to protect the core, so I put a shim from an old 9700pro around it, which fit perfectly after I sanded it down to the right depth.

The last step (since I'm using the stock heatsink while I prep my TEC setup) was to adjust the height of the heatink retention bracket on the mb. I simply unscrewed it from the motherboard and dremmeled off about 2mm from the bottom. Now the heatsink makes perfect contact.

Alot of people say you must use bolt-on coolers once you remove the ihs, but I found that shaving 2mm fromt he bottom of the plastic retention bracket works great.

[carmelo]

Just finished pulling my IHS off, I was a little intimated with some of the things people had said ... but as stated before just be very careful and DO NOT force the razor blade. Just work it around slowly. I found that starting on the corners and working my away from each corner was easier than starting at the opening people had stated they had done. Not saying my way is any better, but it happened to easier for me. This was done on an older NewCastle so we'll see what temps are soon.

The thermal paste seems to be applied well, but mine was fairly hard, almost like putty. Does every one else have the same consistency I do?
