Back at the turn of the millenium, when I still built my own computers rather than buying them off the shelf, this was my processor. It was my first processor faster than 1gig and I was a big fan of AMD for making that kind of power affordable. Today it's so much junk. I shelved the machine when the motherboard went bad and finally got around to recycling it last weekend but I couldn't let this CPU go - it sits on my desk - a reminder of our recent and evolving past.
I measured temps inside the CPU cabinet with the doors open, closed and with the computer asleep. Worst case (as expected) was with the door closed and CPU running.
The temp in the cabinet was 100F and rising.
With the addition of the fans it just about gets over 80F so about a 20F reduction, the temps are now about normal.
Got an older Intel CPU die from ebay to look at under the microscope. Grinding/dissolving to expose a die from a CPU was too much trouble, so I found someone selling these that never made it to being packaged.
This was a pretty cool ad along the Xujiahui interchange tunnel, but good things don't last forever.
