Intel IHS Removal

**CrazyXP1700** · 08-11-2006, 04:13 PM

go around the IHS with the razor blade... some cpu's have resistor banks (like my 805) so only go in around .5cm... you just want to get the RVT silicone off

Put a razorblade in all 4 corners of the IHS...
now this is going to be used to do 2 things
1. it's going to suspend the PCB so that it will drop right out once the solder reaches it's melting point..
2. the razors are actually going to be applying all the pressure that you need to seporate the IHS from the PCB... so you shouldn't have to twist or apply any pressure to it... once it's warmed up... all the presure is just gonna shoot that CPU down... and the razors should be holding up the IHS still

place the razors holding the CPU over a vice, or something so the cpu can drop freely... now you'll want to put some foam or something like that below because it will literally POP off!

Core 2 duo's may be a little tricky... basically you've got a couple of these you've got to pop... i think warming up faster would be the best option... that way one core doesn't pop before the other... circular motions around the IHS would be the most ideal, the heat should transfer throughout... but still a fration of a second later could send one core popping off while the other is still firmly attached... (i havn't done one yet!)

I used a big ass propane torch, a fire maker, 4 razor blades, and a CPU to risk!

Core 2 Duos are real dualcore = Two cores, one die

Kentsfields are two C2D dies on one package. They may be tricky.

I'm gonna do this with a $1600 Kentsfield when I get it

Good job XP, do you know if it's a working chip yet?

**CrazyXP1700** · 08-11-2006, 06:08 PM

nope... im having the same problem with these new memory sticks as i did with the board after i did the volt mod... and (i think anyways, i fried out my fatty D9's)
the board isn't reading any voltages

i think im gonna have to go up to raleigh and stop by tiger direct in the next few days and get a board to slap it into... while i try and fix this one
i might get a 975X board if i can spring it... any donations would be appriciated

ugh... im wore out by this stupid thing...
it's the same problem as before... so i think my cpu is fine...

I machined an Athlon down to get the IHS for a load tester I'm building and I found that the small piece of circuit board was not parallel with the face of the IHS or the chip. I was able to machine it off very slowly using a milling machine and a fly cutter, taking 0.001 inches per pass, until I had the chip exposed. The very next pass just shattered the chip. My point is that it could be done, but I don't know how you would get the chip flat in the vise if you have to hold it from the pin side, I held it from the IHS side which was flat.

it's a combo

i hit it up with my compressor before i fired it all up

i just took the pic in a hurry

Hahah

I like this mans style.

Keep us posted on the 631

**RangerXLT8** · 08-14-2006, 08:36 PM

Dude looking good CRazy! First time I've seen this done. Your method is a bit rogue, but I like the style.

**CrazyXP1700** · 08-15-2006, 02:39 PM

from what i can tell... this is the most promising way possible... it makes the most sense aswell... it SHOULD be successful...

i mean it makes complete sense... with the razorblades under the IHS like that... it's putting enough pressure so when the solder melts, it's going to seportate itself... you dont have to worry about it overheating the core though cause once it's at that melting point... it's gonna pop right off... im a genius!

lack of hardware kinda leaves me hangin though... i dont know if my board has gone out... or my cpu... (if it was my cpu... it could have been before i removed the IHS... cause i attempted removal because i was bored!)

i might try and get my asus to crank up again... i've got some business to take care of first... but hopefully i can take another crack at firing it up tonight

thats my old 520 that i removed this IHS off over a year ago.. . (january 05 i believe)
with that chip... i was heating it up and prying it up one corner at at time... the razorblades is a much simpler method to say the least
needless to say... too much pressure on one side will crack the core... non the less i never heated up the core nearly hot enough

**Qkjhfhaiguihfma** · 08-15-2006, 03:27 PM

love the filename on that one

you do have a sweet method there.

**CrazyXP1700** · 08-15-2006, 05:49 PM

well i fired it up... and i got nothing...
im not getting any vcore readings out of my P5WD2... so that kinda makes me wonder

i even took the heatsink off and put my finger on the core... and it did nothing didn't get scorching hot real quick like my naked celly D did...

so that makes me wonder is it the board or the cpu...
id love to blame it on the board... cause i was adjusting my mods when it last messed up

now i've got to find someone who has a 775 board or cpu in my area to test things out...
(my local compy shop doesn't even sell LGA775 gear... like it's the dead socket

)

OK I gave into temptation and tried your method on my celeron D

My method was basically to cut around like a normal 939/754 IHS to cut the rubber stuff and then to wedge 2 blades under oposing corners of the cpu. I then thought how would be best to hold the cpu and how to heat it up, I eventually decided to hold one of the blades with a wet teatowel and heat the IHS with a lighter. I held the cpu upside down (pads up) and wore a fireproof glove while using the lighter and just kept heating it until it dropped off. The entire process took about 2 minutes, not including thinking time and I found it easier than 939/754 IHS' thanks to it having no smd's. It fits in the socket fine thanks to the way that the bracket dips in the middle although a bit of rubber or something may help hold it in better. The IHS also cleared the top of my bracket so that's fine too. I can not show you it working as I think the m-boards dead but it fails at error code "45" on my diagnostic card which is good as if it's a cpu fault it's code "00".

The next time I do it though I think It would be better to put something to catch the cpu with rather than just letting it drop to the floor

and it may also be usefull to have something you can use to quickly whipe the solder off the core because mines cooled down and is solid now

**CrazyXP1700** · 08-17-2006, 10:22 AM

looks good...
not all cpu's are free of SMD's under the IHS... my smithfield core has them.... (i believe presler, smithfield, and kentsfield have them... possibly more)

clear off that left over solder and take a looksee (pics!!)

i used a guitar pic... or some kind of rounded plastic...
i just scraped it off until i got close to the bottom and had a thin layer of solder on there... (heck you can even use your fingernail) then i hit it up with a small amount of polish to clear everything else off and remove that last bit of solder

you need to find someone else with a board and check that cpu... (same here!)

**Sgoaty** · 08-20-2006, 03:55 AM

CrazyXP1700 your username really suits you

Got to say nice work to the guys who have attempted this. Anyone get their cpu tested as working yet though?

**GordonFreemanLP** · 08-20-2006, 05:33 AM

Really nice work! If your method really works i'm sure all other (crazy :P) people will do that!

**[XC]melymel** · 08-20-2006, 05:38 AM

Well I can give an update to mine, the cpu is dead

but it was dead before I removed the IHS. I have tested it in a friends 925x board and had no go and 45 code still. Also you can remove the solder with your finger nail as crazyxp said so that's one problem solved. I'm trying to get another celery now and I will try again

**CrazyXP1700** · 08-20-2006, 12:37 PM

i havn't been able to test my cpu yet...
i'll probably be picking up a mobo in the next few days... (possibly today)
HOPEFULLY my cpu is not dead... if so im screwed cause i have a memory review to write...

**outcast623** · 08-22-2006, 11:42 AM

here you go guys i tried it on a d830. It would have turned out ok if i knew there were SMD components under the IHS

ohh well i will do it right next time if i decide to give it another go.

I just did this for

s and giggles i dont think removing the IHS will prove to be a worthy risk.

**v0dka** · 08-22-2006, 12:20 PM

This is really promising, it basically shows that removing the IHS is almost as simple as with AMD correct?

Is it a worthy risk, I think it is, Intel CPU's do tend to get hot and with the recent complaints about concave and otherwise bent Conroe IHS's this might be a blessing.

And even though it didnt do much for the A64's I reamoved the IHS from I still did it anyway.

**CrazyXP1700** · 08-22-2006, 01:49 PM

outcast... i said in a couple posts the cpu's that have SMD's under the IHS... smithfield being one cause i killed my 805 because of the SMDS

Celly D Prescott ZX was talking about earlier in the thead (it lived till i crushed the core mounting a heatsink months later) Smithfield, and the 631!

basically if you dont know... google the core name in google images... and there should be PR shot of the cpu without an IHS...

tommorow i find out if the 631 lives

(DFI Infinity 975X)

aleast we know this method can get the IHS off without cracking the core

thats more success than shimano had

**outcast623** · 08-22-2006, 03:46 PM

I did it before you said that

ohh well i was thinking it was going to look like the 631.

**CrazyXP1700** · 08-22-2006, 04:16 PM

yeah... i posted it in the OTHER thread in the intel conroe section (conroes DONT have SMD's!)

preslers, Kentsfield and smithfields... i think thats all that i was able to find

but you did successfully get the IHS off without cracking the core... thats the hardest part!
