Understanding and Controlling CPU Cooling in Win10/Win11

When your Windows computer works hard, whether you’re using it for work or for play, the CPU generates heat. To keep things cool, your computer needs to maintain a fine balance between the fan and processor speeds. And that’s where the system cooling policy comes in.

We’re going to discuss what the system cooling policy is and how to set it so it best suits your Windows PC.

What Is the Windows System Cooling Policy?

The system cooling policy is a set of configurations that keep your Windows computer’s internal temperature cool by automatically adjusting the CPU’s clock speed and the PC’s fan speed. When your computer is doing something processor intensive, and you hear your PC’s fan start to spin louder, that is the system cooling policy at play.

There are two options when it comes to setting the system cooling policy: Active and Passive. The Active cooling policy makes the fan faster before slowing down the processor. On the other hand, Passive does the reverse – making the processor slower before speeding up the fan.

The policy you set will depend on what you want to prioritize between performance and power. So, for example, if you want to conserve battery power on your laptop, you might want to go with the Passive cooling policy.

How to Set the System Cooling Policy on Windows

To set a system policy, start by opening the Control Panel. PressWin + S to open Windows Search, typecontrol panel in the text box, and click onControl Panel in the results. For more ways to launch it, please read our guide onhow to open the Control Panel .

And while you’re there, you can even tweak the minimum and maximum processor state.
