The aluminum pad (made of compressed foil) is thick enough to contact the CPU directly. > Since my recent board swap my poor 2400 is frying.

I wouldn't even think about running it that high. I firmly believe a thermal shutdown drastically shortens CPU life/stability. I hope you're running a 603e/180 (which can still be readily found). I wouldn't be surprised if it died in the next few months and/or random screen freezes increase. My first G3-240 died a few months after a thermal shutdown (and 180 F was about as high as I ever saw, otherwise). I sheepishly confess that my child called me away from TV, so I quickly set my running 2400c down on a black leather couch, forgot about it long enough to find it later thermally shut down. I've always suspected that the extra heat damaged my CPU enough that it eventually killed the CPU. Since then I relentlessly looked for ways to lower the operating temperature. > > Planning on opening the 2400 up and making sure I have a good contact > from chip to heatsink which I suspect is the problem.

I wish you all the best but do let the list know if your CPU fails (just for our collective improved knowledge base).
