The datasheet is rather clear about this, as you said - although it doesn't mention whether analog output amplitude modulation or PWM is used, nor does it states how temperature interacts with the final speed. The fact that temperature somehow matters may explain the strange behavior you noticed. Note that I suspect that fscher isn't correct on some points. It seems to create files named fanN_pwm (old standard) instead of pwmN (new standard), and also maps fanN_div to fan ripple registers, while these are two different things. I won't blame Reinhard Nissl too hard since I might be responsible for some of the errors, as I gave him possibly unenlightened advice while he did the work. -- Jean Delvare http://khali.linux-fr.org/
