Need to remove CPU from heat exchanger

  Belatucadrus 11:12 21 Aug 2004

I have encountered a problem while attempting to change the CPU cooler on a pentium 4 Medion Life PC. When I removed the old fan/cooler assembly the CPU came with it and is quite firmly stuck to the base with a very resilient somewhat waxy black thermal compound, so now I can't remove it in order to replace it in the motherboard.

Sensible suggestions as to how to remove it without damaging it please

I've never tried this but how about a sharp, thin bladed knife?

This is for Arctic Silver thermal compound, but the instructions apply to all.

I would have thought a drop if isopropyl alcohol would loosen the adhesive, ehough to begin to lift an edge, then apply a drop more and so on til you can separate the heatsink from the CPU.

Another place to go would be the manufacturer of the PC - their website may have specific instructions.

A big NO to the knife, too much risk of damage to the CPU.

Problem solved, I warmed it gently and applied a little pressure to the chip, which finally came off. I'm now of to PCW to get some compound so I can put it all back together.

The new fan doesn't fit in the existing mounting, but that's another story. Still today can only get better.
