bios cpu fan control question

post #1 of 3
Thread Starter 
Right now my smart fan settings are:

Fan Mode: Enabled
Smart fan mode: Normal
High limit temperature: 60
Low limit temperature: 37
High limit PWM: 200
Low limit PWM: 56

what the heck is pwm? I can set it up to 256 max.
How do I set the fan to run at max speed if cpu temp reaches 60c?

PWM means pulse width modulated. The fan is wired differently than constant speed fans so the motherboard can vary the speed based on the temperature reported by the cpu. Your mobo will automatically increase fan speed, so try changing the high pwm limit to 256. If that can't be done see if you have different modes in your smart fan settings - 'extreme', 'high', something like that. Also try manual mode and see what is reported.

Finally, try googling your mobo for fan control settings.

Change Smart Fan Mode to Manual, then set your high/low temp limit.

Although it's not mentioned in the manual, the high/low limit PWM settngs are most likely the time (in ms) the fan reacts to CPU temp changes. Just leave it set to normal for now.
