Hi, While trying to control the CPU temperature with the fan speed on a P4P800 motherboard + P4 CPU with the w83627hf driver (kernel 2.6.11-rc4) just like Asus's Q-Fan (see http://www.wingding.demon.nl/ for qfan.rb), I encountered a strange effect. Doing cd /sys/devices/platform/i2c-1/1-0290 echo 240 > pwm2 sleep 1 echo 192 > pwm2 .will stabilize at a fanspeed of around 3229, while changing the 240 to 128 will give a fanspeed of around 2136. Somehow a 'state' is kept somewhere, or the driver has a bug. Is this a known bug?
