Removing the heatsink from a PII

[pscowboy]

What is the technique for removing the large aluminum heat sink from a PII and installing it on another?

I tried an Allen key on the four silver heads; but they wouldn't budge. Are they screws? Or, are they rivets?

rivits...

I assume you are working on the secc1 package...

you will need to disassemble the whole cartridge...don't expect to be able to reuse it...you will most likely damage it when removing...but the plastic does absolutly nothing (ok maybe it helps support the cartridge in the socket...but it is not necissary)

If you are planning to put this on a slot 1 piii...Kudos to you!!

Big pII heatsinks with a moderate size fan on a piii make for a great cooling solution...for more info on putting an secc1 heatsink on an secc2 cpu just ask...

Anyhow...once you pry open the big cartridge (after pulling out the hack saw ) you will encounter 2 metal clips that are putting presure onto the PCB the cpu is mounted on...you will have to carefully bend away the chunks of metal (on the 2 clips) that are digging into the 4 pins that hold the heatsink to the processor...

Once you remove them (the pressure applying clips) you can bend the "chunks" that grip the pins back to their original state and re-use them...

Sounds confuzing but once you crack the cartridge open you <i>should</i> see what i mean...

Nope, these are not rivets, they are indeed screws.

They are screws that look like rivets. They use a small Torx bit (aka star bit) to remove, and sometimes that doesn't work. The last one I had to remove, 3 of the screws came out and the other one refused. The aluminum heat spreader was strong enough that simply prying a little stripped the threads off the last screw, and I carefully removed the left over metal.

Hmm, large gold heatsink perhaps? Funny thing, they look like rivits because they have thin, flattened heads (like rivets) and the holes look round (because they aren't well formed). But find me a rivet that has threads!
