I am running 2.6.17-1.2145_FC5 on an Athlon XP2000+ using athcool. On
previous kernels, my CPU temperature was about 39 C with athcool on or
50 C with athcool off. That was really nice, allowing me to run a slow
fan, etc. I had no stability problems.
With the present kernel and athcool on, I get 46 C, rising to ~50 C with
athcool off.
Maybe there's some process hogging the CPU so it runs hotter? Did you try with athcool off?
