Yes, you can connect a CPU fan directly to a fan header on a motherboard we disable PWM and bypass it because it is not how to make a computer be quiet. You'll need to check your BIOS to see if there is a setting (there should be) to change how the fan controller works most mobos have a fan setting for CPU that is silent, normal, full speed. If the fan is starting and stopping, either the fan has an issue (more likely), or the fan controller has an issue (less likely). The fan speed is modified based on heat and other factors.

With Pro version you get extra features (custom fan presets), priority customer support and confidence in future updates and improvements.PWM means that the speed of the fan is controlled by an onboard controller in the motherboard. Under "Control" click "Custom" and you can then use a slider to change the fan control on your Mac".
