No experience with that particular HW, however, I just returned, with
my Dell Dimension 2400 box, from a visit to the motherboard repairman.
I thought the Exhaust Fan for the CPU was dead (and the motherboard
damaged). He told me that when that fan runs, it rotates very slowly
(unlike the fan in the PSU) and that it probably doesn't run very
often. Each time he touched the Shroud over the CPU, it was very cool.
I read something in a forum, that said the CPU temperature can go to
100 C., in a few seconds, but I now wonder if that is true or not.
Hopefully, as the previous reply indicated, lm_sensors can tell you
what's going on. My box has a new ATX PSU and I'm *very* thankful Dell
did not install a proprietary PSU and mobo in this model!
