Re: HP Fan

I have/had an HP laptop as well, and it suffers from the same problem.  It's caused by the fact that the machine simply runs hotter in linux than in windows, and so the fan spins faster in *nix, in an attempt to keep it running at the right temperatures.  I recommend against trying to change that behaviour (fanspeed, etc.) manually, but if you can enable better power management settings and get the machine running cooler (or get a cooling mat for the laptop maybe), it should solve your problem that way.

Hp 6715s AMD64

Do you have all modules needed (cpufreq_... + amd driver)?  I'm on 43 now, average 41, as in windows (almost).
My fan is hardly used. Governor is ondemand. If I don't specify the right modules (starting with powernow-k8) I
get what you describe. "modprobe powernow-k8" silences my fan on clean Debian and Arch installs (neither guess my
cpu right, only Ubuntu).
