Hello Hans, Your proposal sounds fine to me. I wasn't too happy with the fan?_target pwm? conflict either. So I will implement the following: 1. Remove fan?_target. 2. Add fan?_full_speed. 3. Interpret pwm? as the duty cycle when in duty cycle mode. 4. Scale pwm? from 0..255 to 0..fan?_full_speed when in rpm mode. 5. Change the behavior of pwm?_enable not to change pwm vs. duty cycle mode. 5. Add module option to select rpm/duty cycle mode. 6. Add pwm?_auto* This will take some time of course. (Although being able to read the temperature of my "Asus EAH3650 silent" would speed things up ;-) My BIOS doesn't put a usefull value in the full speed register. There is also no way to set the case fan to anything but a fixed PWM value. Then again I build the computer from seperate components, I can imagine a fully assembled system could do more. regards, Mark van Doesburg.
