BTW, when I test installed SUSE 9.3 the fan was not always on. It was running more or less the same as under windows: under the low processor load (600MHz) it was turning on every
12-15 mins for 2-5 mins depending on how hot the computer was. With new BIOS 1.10 it was possible to figure out that the fan turns on at 55°C and off at 50°C. However, I also observed some exceptions from this rule which I cannot explain.
Under windows when I was measuring the temperatures using mobile meter the temperature dependence of the fan activity (even at low processor load) was not obvious. Probably mobile meter is not showing the temperatures correctly (one of the evidences is that when I start some application which needs more processor speed to start, the temperature suddenly jumps for several °C and the fan turns on).
Try to ask people on uniwill.com/forums
. The linux thread is rather dead there but maybe someone will respond to you. I am also interested in the discussion running.
