After upgrading Win10, the fan is ringing, the fan is rotating at a high power.

After upgrading Win10, the fan always turns around? At this point, consider changing the system cooling method. In the system default state, the heat dissipation mode is “active”, which means that the fan speed is increased before “lowering the processor speed” when the heat is relatively large.

If your computer fan continues to rotate at high speed, consider Change it to "passive", meaning "lower processor speed before increasing fan speed" to reduce heat generation. Of course, this has an impact on system performance. You need to make a trade-off.

This setting option is also available in Win7 and Win8.1 systems.

Change the system cooling method. Steps

Open the Control Panel—Find the Power Options and click on “Change Schedule Settings” after the selected power plan;

Click on “Change Advanced Power Settings”;

Change the system cooling method to "passive" here, OK~
