metal thing located the chip

[johnnyw]

Have taken the dust from an old computer ( actually a pentium 100 mhz) which had previously a 150 mhz chip overclocked to 180 wiithout anythnig added in order to cool. I had to change the chip since I am unable to take a metal stuff attached to the cpu itself. So if I can´t take this I won´t be able to start my watercooling ( I am a real newbie in this field)
Should I try to remove this by force or it is useless and all I will do is damage the cpu?

Do you mean that the heatsink is glued to the chip somehow?

[Mizzery]

it might be a heatspreader (like on k6-2's) but as of my knowledge pentiums didn't have them, they were just ceramic chips with heatsinks on top. The heatsinks i came across were usually held on by a clip and had (not enough) thermal grease between the cpu and heatsink. A fan is a good idea on those pentium heatsinks for overclocking.

If its glued on try putting the chip in the freezer (in an antistatic bag of coarse) and then try to get it off. I removed the plate from my k6-2 with a screwdriver but I wasn't carefull as it was already dead. It was glued on in the four corners. I slipped a screwdriver between the plate and chip and pried.

what do you mean by in "an antistatic bag "?
btw, the fact is that I don´t know wether you had seen this type of heatsink already stuck to the cpu , but this is the way it is. May it be possible that the two of this parts are not even soldered or glued maybe taken out in one piece?

I wouldn't even bother trying to take it off. It's epoxied (glued) on there. Even the freezer trick probably won't work. There's a lot of surface space for the epoxy to settle into, and the surface is porus to start with. The odds of you cracking the chip are better than the odds of you getting that heatsink off. But who knows, it may come off, it may not.

Look at ebay for a super sheap replacement chip, might save you the trouble of wasting your valuable time on a two dollar chip:)

Mizzery, thanks on the av. I made a few others so it's hard to decide.

If it's a round looking heatsink, maybe it unscrews. I was confused for a little while when I first met one of those. Had a really low profile clip that it screwed into, was only when I bent the socket lever out enough to clear it and get it and the CPU out together that I figured it out.

I think it's more likely it has a sticky thermal pad on than it is epoxied in place, and those usually give way with a good twist of a screwdriver under the edge.

I've inherited a large number of the old pentiums with attached heatsinks over the years- they have ALL been epoxied on.

I have taken a few off and don't remember killing any of them that way (although I didn't run most of them for long.)

Replacements can often be found cheap :)

What d you mean by replacement ( never heard of them ), obviously when atlking about cpu´s
