Folks—

I've been searching the net far and wide, and I just can't seem to find a solution to this problem. I'm running Kubuntu 10.04 LTS 64-bit on an HP Pavilion dv5-1002nr, have compiled and installed k10temp, and generally have a healthy system which tells me how hot it is. The CPU is an AMD Turion X2.

The problem I face is that there appears to be neither documentation nor hack in order that I might have the CPU fan run based upon temperature as well as load. Currently, I'm looking at a CPU load of around 20% and a CPU temp of around 75C, yet the fan is still at the low end of its speed domain.

I've looked in /proc/acpi/fan to no avail (the directory is empty).
The fan ignores the "Always On" BIOS setting.

Is there anything that anyone knows of that will help this situation? I'll take any pointers I can get (preferably valid, and preferably of type char*), and I'm also willing to dig into low-level stuffs if necessary.

Thanks ever so much,

Henry
