My computer fans speed up and down whenever my cpu use twitches. The varying sound of the fans is very annoying so I installed SpeedFan to try to fix this.

I have fiddled with the SpeedFan settings but can't get them to work well.

Either it's just like before or it doesn't speed up the fan enough.

My first question is.

What is the difference between these settings (For PWM mode).

  • SmartFan 3
  • SmartFan 4
  • Thermal Cruise
  • Fan Speed Cruise
  • Manual
