Is this a known problem and will/can it be solved somehow? PWM doesn't work on all systems, depends on how the chipset is wired by the motherboard manufacturer. You should read this document: http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/doc/fancontrol.txt And then try user-space tools from the prog/pwm directory. But in any case you want to fix the fan speed readings before, or you won't go anywhere. Note that we have another driver for the W83627THF but it hasn't been ported to Linux 2.6 yet... When it will be, you should get better results using it than the w83781d driver. If you're interested in porting it yourself, let me know and I'll tell you everything you need to know. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
