ISH Removal for e21XX series CPUs

[LightSpeed]

thanks!

but but but, i scraped a little bit of green right at the edge, revealing gold. i guess that is the end of my e2140


no electrical wires/whatever its called is there tho. lets see what happens

i managed to get the blade under two corners. two more to go. seems difficult, i guess this razorblade isnt thin enough, but i wonder how it can possibly be thinner than this

[FrogBite]

Use women razors instead of mens. They are thin and flexible.

[cc-tuner]

You only have to get it under 1 corner then just slide across all the other sides when the corner off the razor is betweens te chip and the IHS, this should go easy..... And with some green popped off your cpu won't be death

[LightSpeed]

ok, i might sound like a complete noob, but after removing 3 A64 IHS's, this is very weird

i always used a mens blade. soaked the cpu in nail polish remover, and started cutting the four corners, slowly working my way towards the middle

here, however, the rubber sealant is VERY thin. pushing the blade in was very hard, and i can NOT move the blade (hence i cant cut towards the middle) after i push the blade in. i guess a thinner blade is the only way to go. can anyone post pics of blades they have used to remove core2 ihs?

if i take a blade out of a triple blade razor, i cant apply enough pressure to cut because the blades are too flexible, hence they wobble

i feel stupid. never even had to post for A64 IHS. grr@intel

thanks for all the replies!

why do you soak the cpu in nail polish remover?

[LightSpeed]

the A64 silicone or whatever they put between the IHS and chip gets softer, or atleast thats what ive heard. and it hasnt damaged a chip so far. nail polish remover has acetone, so it can be a substitute to pure acetone, albeit less strong

i finally cut one side of the chip. the top part of the cpu seems hard, theres this plastic thing over there. how did u guys cut that part?

[Bail_w]

plastic thing? what you mean?

[LightSpeed]

nvm, the rubber on the top of the cpu seemed a lot harder to cut

its just a matter of getting the right tools, honestly. someone said it in his post. its easy tho, a very, very thin blade is required.

gna power up the cpu in a bit. hope for the best, i hve a feeling its dead

thanks for all the help everyone, very much appreciated

I removed the IHS on my 6300.

The processor is 100% functional, but no difference in the temperature.
I used a cutter and lighter.

[initialised]

i just received an e4500. did some research found it wasnt soldered and jsut did her up like the AMD days. and bam off it came.. just use some tape to hold the cpu in the socket then mount my water block and whalaaa 20c drop on load, from 70c orthos load to 50c orthos load. with 1,7 volts love getting cheap ass cpus.

Peace, Love & Respect.........

Sound's worth a try, I'm stuck at 3.4GHz due to thermals, have booted at 3.7GHz (410x9) and made it to Windows at 3.6GHz (400x9). What's your E4500 running at?

[fragmasterMax]

I tried to remove the IHS from my 2180 today but had no luck. I couldn't even get the razor blades under the 4 corners

dude your probably using a utility knife blade, get a razor from your local hardware store, not a utility knife blade

[TheMysticWizard]

Okay, Results are in.

Now before someone says my temps are awful high, my room is constantly at 72-74*F (22-23*c). This is my secondary computer, therefore I tried to put very little money into it and used pieces I had laying around from upgrades and such to my main system. The case flow leaves little to be desired, 2-80mm Intake fans, 1-120 Exhaust, plus the 80mm PSU fan. The CPU is being cooled by a cheap Cooler Master Hyper TX2 and is running at 3.0 GHz (333 x 9) at 1.442 Vcore (Actual, under full load via DVM). This e2160 is running on a Asus P5B Dlx (rma'd from asus) which has been v-droop modded, the board is otherwise stock, down to the cooling.

Originally my temps were between 68-69*c under full load, this remained steady after several mounts with AS5. These temps seemed VERY high to me especially since I'm not pushing THAT much voltage to the chip.

Once I pulled the IHS off and got the heatsink mounting resolved, I am now seeing 55-56*c under full load, same voltage and everything. This seems much more reasonable to me. I am guessing Intel really fudged up the Thermal "Gum" under the IHS if I am seeing this much of a difference.

So in the end... about 13*c difference.

Here's some pictures, sorry for the bad quality.

Before. Bad Pic, sorry...


Un-Capped:


Cleaned up Die:


Was it worth it? In my opinion, yes.
Was it hard? No, not really, I was just a bit nervous doing it.

Nice work! Looks like a phase-change pad instead of solder, bad Intel, bad bad Intel, lol.

Looking at this makes me want to some surgury on the gf's 2180 doing 3.2 Ghz on 1.4vcore but at ~70C top Orthos temps (should be lower for sure compared to how my E6600 was using the same parts). Thanks for the test!

[neouser]

do you think i could do it on my e6750? I am going to put it under liquid cooling. Ps, the socket can block the cpu once the ihs is removed?

[JamesBong420]

Sound's worth a try, I'm stuck at 3.4GHz due to thermals, have booted at 3.7GHz (410x9) and made it to Windows at 3.6GHz (400x9). What's your E4500 running at?

im running 1.7v load 3.7ghz. 3.82ghz 1.76v load. its a cheap cpu and havent had any issues yet lol

also my chip doesnt like more then 412 fsb. these 4500s are so lame on the fsb. so im doing 380x10 or 412x9

[Vatos_locos]

what about E4300 cpu's are they solded or with thermal paste ? anyone tryied with E4300 i want to uncap him and see if it will give me more Mhz

[vortex240]

I figured I would share my results since I got the idea to remove the spreader from this thread and it helped a lot. I have a e2180 and I was able to remove it quite easily with a sharp, thin, flat razor.

Before the removal I was able to oc it to a max fsb of 425. Afterwords the max fsb didnt change but max oc did. Previously I was able to get 3537, so thats 9x393 @ 1.5v with the vcore drop control disabled. I have a DFI P35-T2R, in my opinion best board to oc with. I use a lapped big typhoon with the stock slow fan. Temps would be 37 idle 85+ load.

After the removal I can oc to 3700 with temps 33 idle and 74 load but thats with a vcore of 1.575v.

At the previous oc and 1.5vcore the load temp dromped a massive 20 deg C

Intel really screwed up on these heatdpreaders.

[fng77]

I´ve done it too. Got 5-10 deg. lower temps with my lapped zigmatek

[Demo]

How i wish intel offered a topless Q6600 out of the box

[deadsix]

Dunno wot the fuss is all bout


seems soo darned simple


im not doin it though, i just lapped
all that lapping for nothing? naa, i keep the top on!

[chatmaster]

How are all you guys securing the CPU's into the socket without the IHS?

Do you use tape then screw the HSF down further to compensate?

Do you have to modify the socket much? take off the hat piece that goes around the CPU sides?

Do these core look identical to the 4mb cache cores? disabled cache?

[vortex240]

I took the clamp off, easy. Then I places 4 circular stick on foamy dampers on each corner of the cpu itself. Then screw the tt typhoon on to the die itself. I found it that the pads were needed on the corners for the hs to push down on the cpu. It would not boot otherwise suggesting poor conductivity somewhere.

[Rutku]

I'm think that i'm going to do this to mine E2160. It doesn't boot anymore. I was making it straight with sandpapers 400->600->800 and 1000. After 400 paper it does boot and works fine but next time i tried it (after 1000 paper) it doesn't give picture or anything. I will try E2160 at my friends motherboard and if it doesn't work, i think i try this. There's maybe something under IHS (or so i think), maybe there is something like copper "dust" under it. Do you think it might still wake up? Or is the all hope lost ;/ ... Sorry, my English suck , but hope you understand all. Ask if you don't, I'll try explain it better = )

[Moc]

How should the dust come under the IHS? I don't think so.

[G.Foyle]

How should the dust come under the IHS? I don't think so.

There is a small hole, right above the code imprinted on the substrate, but there is no circuitry under the IHS - the copper dust would have nothing to short, if it really got there.
