How to Turn on PC Fans

Methods to Control PC Fans

BIOS/UEFI Settings:

Entering BIOS: Reboot your computer and press the designated key during startup (Del, F2, F10 or F12) to enter the BIOS.

Finding Fan Settings: Go to sections named Hardware Monitor, PC Health Status or something similar.

Adjusting Fan Curves: Look for options to set fan speed based on temperature. You can create a custom curve or choose from presets like silent, performance or balanced.

Save and Exit: Make sure to save your changes before exiting the BIOS.

Fan Control Software

Manufacturer Utilities: Companies like ASUS, MSI and Gigabyte provide their own fan control software for their compatible motherboards. See if yours comes with a specific software like that.

Third Party Options: Programs like SpeedFan, Argus Monitor and Open Hardware Monitor offer fan controls sometimes with more granular adjustments than BIOS settings.

Adjust Speed Profiles: These programs let you fine tune fan speeds, set temperature thresholds and create custom profiles for different usage scenarios.

Fan Controllers

Dedicated Hardware: These devices connect to your motherboard and provide physical knobs or displays for direct fan control.

Offers Precise Control: Fan controllers provide hands on and real time speed adjustments.

Important Things

Not All Fans Are Controllable: Simple 3 pin fans can only run at a default speed. 4 pin PWM fans come with speed control.

Airflow Matters: Make sure your fans are installed in the right orientation for the best intake/outtake.

Temperature Monitoring: Keep an eye on CPU and GPU temperatures using tools like HWMonitor to make sure your fan adjustments are actually effective.
