Core 2: remove IHS or not?

[dr_sharp]

Hi guys,

I was wondering how many people have removed their IHS... I just saw coolalar had his removed... and he's my idol.

Is it difficult to remove?

Thanks,

[M.Beier]

Coolaler has more then just 1 CPU, sure it wasnt one of his meroms?

And yeah, its quite difficult..
You need to:
1. cut the sides so its not attach with other then solder (thats all you do for A64 basicly)
2. Put it upside down, and warm the sucker... - keep it 90-100 deg warm for.. hmm, some time - then it'll fall off..

But seriously, no good idea to remove in LGA775

[HaxR3]

Very hard, its soldered on & if/when you do get it off the cpu mounting mechanism no longer works, so you have to improvise there

The temp drops are 1-2*C so if i were you i would just not risk your new £150-£600 cpu & just save a lil for better cooling

Unless youre on LN2, Dry Ice or Phase of course!

[tardbus2]

I'd stay away from removing IHS, as it's really not worth the trouble of possibly killing a nice new processor.

You are better served by going to the auto parts store and getting some 800-2000 grit sandpaper.

I duno how did it but i got shown a pic and it's been done!

The die was lapped and clean and temps were a hell of a lot lowerr and ran on phse it clocked tons more!

[HaxR3]

Lapped die?

*Somehow* I dont think so seeing as the transistors are less than 0.01mm from the surface of the die on chips that are protected by an IHS

[Barracuda]

it is not a good idea!

[ted3]

Yeah right, lap the core, use a grinder also maybe?

I think mr Beier is correct, must have been one of mr Coolalers Meroms you saw, Meroms dont have IHS and it would look "lapped" in a way.

[kenkerkutiv]

If you have a lot of experience and you NEED break some records soon to hurl you conroe, do it

I just saw coolalar had his removed... and he's my idol.

WJAJAJA, LOL!

The consensus is that its very hard to do without damamging the core. You also break the lockadown mechanism, and most standard cooling mounts when you do it, so youl have to make custom soltion for those while your at it.

A lot of people have tried, but I have so far not actually seen one who managed to pull it off without killing the CPU. (im not saying noone has, im just saying I haven't seen one, even here on XS). on the other hand, I have seen quiote a few C2D's that this was attempted on, and where the core was ripped in half, or torn right of the CPU-PCB.

All in all, don't attempt it unless 2-3 degrees are super critical for you, AND you can afford to lose a C2D and get a replacement.

if you're in ym situtation and getting 64c load temps on STOCK VOLTS, its kind of worth it. Yeah its soldered, but that doesn't mean its good solder, or even good contact. Obvously its not. Not when my x2 3800 @ 1.5v and 2.7ghz was getting 20c lower temps with the same water setup.

As for a custom mounting solution, you can put 4 -5 layers of electrical tape along the edge of your cpu. Or layers of foam, what ever. You also eed tpo shave your heatsink/waterblock to fit inside the socket hold down. and also use 4-5 layers of electrical tape for "feet" around the core so you dont crush it.

thanks guys, I was just curious and hadn't seen much discussion on it.

Dont trust mobo temp-readings, simple as that

lol yes... i was getting -50C core readings from my board on water.

[menlatin]

@ stock speeds i get 32-33 idle. and about 45c load. Ambient about 28c, As i bring the fq up the temps just keep going higher and higher. Core temp and Easy tuner read pretty close together, and both give me low 30's idle at stock speeds. My readings are actually about right so that leads me to believe the IHS contact to the cpu is crap.

Nice to see your watercooler taking his work very seriuosly

i succesfully removed the IHS on my 631 recently... cracked the core mounting my scythe ninja (always hated that mounting system)...

heres a thread with all the stuff that i ran into while removing my IHS...
it can be done... its risky as hell... nobody has done a conroe or allendale yet... so be xtremely careful for SMD's (conroe core on google shows no SMD's, nobody has yet to varify AFAIK) but it would be nice to find out

[M.Beier]

I spoke with coolaler earlier, he told me he's never done it, and didnt thought it was possible doing Showed him the guide on VR-zone by shamino
- Then I told him it was 2AM here, and he told me to get to bed, heh

Well actually, Im on my way to bed, just had to stop by lookin' if another member has been added a new title.. (Banned)

[CrazyXP1700]

I talked to shimano about a week ago... showed him my method... (he said it was very smart ) he's going to give it a shot when he finds a cpu worth risking...

never thought of showing coolaler though...
other users have removed the IHS without cracking the core... one user did it to an already dead Celly D... the other cut some SMD's off his smithfield (i was guilty of the same thing) both removed the IHS without cracking the core

[M.Beier]

I got an idea..
Cut the stuff in the sides with razorblade, like on A64's..

- Visit the local swimming facility, head for the sauna, attach the CPU to the roof with some gaffatape in the corners, read the newspaper while waiting for the IHS to hit the floor
Sound like a good idea, aye?

[CrazyXP1700]

oh i would love it if it were that easy...

hell id have to remove IHS's just about every day then

[menlatin]

i'm going to try it soon. I just wish i had a dead cpu to practice on atleast once.

[kemist]

Mind i dont have a lga 775 to even look at, but theoretically would it be possible to just take the top retention bracket off and use your waterblock to actually hold the proc in the socket?

P.S. you CAN lap your processor, at least AMD's. I have an opty 165 that i lapped, they are concave. Look for a post by madmikee for pictures of his, its where i got the idea.

The thread doesnt have pics anymore though cuz its been archived.

[CrazyXP1700]

you could do that... just a higher risk of bent pins and such when your removing blocks...
