System Cooling Policy allows you to specify the cooling mode you want to use for your Windows-based computer, for which you have two options: Active and Passive.

• The Active setting increases fan speed before slowing the processor to main cooling. You’ll get the best performance by leaving the System Cooling Policy set to Active.
• The Passive setting slows the processor before increasing fan speed. If the fan is always running and you would like to make it quieter, you can choose to opt for the passive mode.

In this tutorial we’ll show you how to change the system cooling policy in Windows 10, 8 and 7.
