One other thing you might do if the cpu fan stops or slows down and the cpu
overheats is to regrease the heatsink. One of the cpu's in my dual Tyan
overheated and vaporized the grease between the cpu and the heatsink and
hardened the grease around the perimeter of the PIII. Surprisingly the cpu
still functions fine after the regreasing and fan replacement. Just for fun
I ran the machine with one cpu to see what w2000 and ts2000 would do. With
two cpu's TS2000 never froze, with one cpu the cpu useage went to 100% and
froze. I had been trying to conserve electricity by running the air
conditioner at a higher setting, not a good idea as the overheating was
agrivated by higher room temperature. Now the room temp is kept at 80
degrees F or lower.
