I don't know how, but under Windows, the fan turns at low speed or at high speed. With "cpuburn" active, the fan is at high speed, if I stop cpuburn, the fan gets back to low speed. I notice with the program "PC Wizard 2005" that the minimum cpu speed was around 661 MHz ( Under Linux, the minimum I can get is ~798 MHz): ----------------8<---------------- Processeur : Intel Pentium M 760 @ 661 MHz ---------------->8---------------- The temperature seem to be 52=B0C, but the value doesn't vary. So the fan souldn't act differently if only hardware based, should it? Is there a way to speed down the CPU to 661MHz?
