Automatic Fan Detection

In computer BIOS settings for Intel desktop boards, Automatic Fan Detection is a fan control option for detecting fans added to the motherboard. Users can select the following settings;

  • Next Boot: Detect fans added to the motherboard upon next boot only.
  • Disabled: Will not detect fans added to the motherboard, new fans may perform erratically.
  • Always: Detect fans added to the motherboard (may cause a slight delay and increased noise during startup).
