Intel IHS Removal

[[486]]

i saw someware someone used a cigarette lighter to heat the ihs and as long as the flame doesnt touch the chip youre fine, then use a soldering iron and solder wick to clean the solder up, then use the outer edge of the ihs as a shim and the rest as a keychain

[guess2098]

can't do it.
i tried once and CPU = died!!!!!!!!
it is totally different then AMD.....
core is like super glue with IHS

[MeltedDuron]

very few chips are superglued... you probably didn't heat up the IHS enough.

[Pipi]

dead conroe... try it with a working one! no risk - no fun!

That would be wrong. Imagine if the IHS is secured in a different way and he'd kill a good Conroe CPU. Imagine the waste!!

[Thrilla]

Why not hold the chip up side down in a liter of hot water. This way you can control the water temp, and have enough heat capacity to melt whatever solder is in there. Though you'll need steady hands, or risk using distilled water (my wc leaked and the distilled water didn't kill it, I didn't realize that till I saw water on the mobo haha.

wasnt it about 70°C?? thought someone (bbmods??) postet it some time ago over at hwa)

Yep BBmods got confirmation from intel that the solder melts at 77C The core can take upto 140C though so it's safe. Although the performance benefit of removing the IHS. over just lapping it is far out weighed by the risk for me.

Just lap it man

Or you wanna try removing it on x6800?

[epox4life]

I did it with my Celeron D 341 before, I got the IHS off with the core still intact.
But I must have cut some traces on the chip with the razor blade I used because its dead now.
I now have a Celeron D keychain.

When the contact between the ihs and the core is that good, removal will gain 0% higher clock's imho.

for the people who want it still, why not grid it off, take some time but the heatspreader is not that massive, maybe start with a file.

Look @ VR-Zone, there is an article about IHS removal

[mr_knowitall15]

heh looks like shamino f-ed up two cpus. Looks like it pretty much cant be done.

Actually it can. You need to heat it up to 77c and then you should be able to get it off.

[MeltedDuron]

screw temps, you heat it up until its hot enough! shamino was too paranoid, holding a small butane torch or heat gun to the ihs with very gentle prying will get the ihs off no problem, as long as you dont heat it for too long and melt the solder on the other side of the die.

[.sentinel]

I am just saying thats when it melts. The cores can take up to 140C.....

[[XC] Lead Head]

shamino pried upwards, wich lifted the core off, if he had twisted, he would have had no prob

[n00b 0f l337]

You can do it with a larger tipped soldering iron, I know this for a fact.

[[XC] moddolicous]

How good a thermal paste can solder be?? I mean, I can almost completely say that there would have to be a decrease in temps if it was done right. How could there not?? Unless the solder is like >80% silver (which it cant if it melts @ 77c) then I think there would have to be a decrease in temps (unless the die is completely ragged and jagged or something).

[guess2098]

i heated it up to 95C but still can't remove it... haha

OK anyone saying this is doable I suggest you post a pic of one you have done yourself.

[CrazyXP1700]

Naked 631!
done with the torch method...
i took 4 razor blades in each corner...and placed it in a clamp suspended... I set it so the IHS was above the blades (so the cpu would drop when it let go)

i heated up the top until it just popped off





Not 100% sure if my cpu survived... but it sure looks like it...
i've got to get a memory stick soon to throw it in and see if she'll boot

prayin like hell that it does
(5Ghz on air? hopefully)

[\Karting_freak]

77с?
hm, some people say it has indium solder, which may be true then. its melting point is a bit above 60c, cant remember now for sure

[outcast623]

crazyxp that looks very promising, please keep us updated as to if it works or not.

[CrazyXP1700]

well... i polished up the cpu abit...
i went to install my Scythe Ninja... and it's not making contact with the die...


no not a kingston plug (i dont think i even have any kingston sticks)

so definetly going to have to modify some coolers to go IHS less thats for sure
i think my old chilly1 tube might have cleared it... but i dont really think so...
so some modifications might be needed...



so fun!
gonna break out the dremel and shave it down about 1mm all the way around the green and see if it'll make contact

would be nice if i had the proper equipment

[CrazyXP1700]

tada!

looks like hell... but it's making contact...
now i just gotta lap the base of the heatsink with some 2000grit paper and i should have the best contact possible

would suck if this cpu was actually dead
i need to aquire some money to go pick up some new sticks...

i killed my D9's because my stupid multimeter wasn't reading properly

[CrazyXP1700]

im gonna go and take some pics of how i actually heated up my 631... so you people can see... anyone brave enough should be using my method...
shimano's is horrible
he would have had better luck inverting his cpu so that the IHS was locked in the vice... and twisted the PCB when it was all warmed up... thats how i did my first successul IHS removal on my Celeron D

im tryin to get out and get a new memory stick from the local store (staples... and they have 512 sticks with D9's! not fattys though... their 1GB PNY looks to be fatty's though, but their under heatspreaders)
but my brother just stole my car (he blew up my jeep a few months ago too!)
