How do I change my cooler's PWM settings?
The PWM settings can be configured using appropriate software or directly in the BIOS, which is better. The curve is often configured using key values. This means that a temperature is assigned to a percentage value. If this temperature is reached, the fan rotates above the speed previously specified using PWM.https://www.arctic.ac/en/CPU-Cooler/How-do-I-change-my-cooler-s-PWM-settings
