tips to remove passive heatsink from Pentium II processor

Al Garay · 13th March 2005, 09:09 PM

Any tips on removing the aluminum heatsink from a PII processor? The heatsink looks to be mounted using 4 screws with special type of star socket-head. I tried drilling through the screws but the heatsink is still tightly connected? Could it have been glued?

Is it a slot1 CPU?
Picture?

i think i did what you're trying to do before, just can't remember if it's a PIII or PII slot 1

you have to use a flathead screwdriver to separate the main heatsink to the thin piece of aluminum plate directly attached to the core, i think intel used some thermal paste and the screws that you already drilled to stick them together

goodluck,

I did this a few times and I remember having to take off a couple of clips, the kind that you have to squeeze and pull through.... But it was too long ago for me to be able to explain the whole procedure.

Passive sinks are often glued with thermal epoxy stuff. Try sticking it in the freezer for 15 minutes or so, to make the epoxy brittle, then with a flathead screwdriver gently try and pry it from the cpu.

I could be totally wrong about it being glued though

Thanks for the tips. The Pentium II is a Slot 1 processor with a very nice aluminum heatsink.

I will try sticking them in my freezer and seeing if that breaks the seal of the glue/epoxy.

The slot 1 PII had 2 retention clips that have to be removed before you can separate the assembly. A pair of needle nose pliers usually works well.

I'm not really sure about a Pentium II specifically, but often the heatsinking compound paste that is used for these things will dry out after a few years and really need a bit of force to get off. You might need to use a lever of some sort.

A heat gun helps for that, thevoice.
