CPU_FAN and CPU_OPT are entirely different and serve distinct purposes in the context of a computer cooling system. CPU_FAN or CPU Fan Header is the primary 4-pin fan header on a motherboard, and it ...

Fan Control is a great tool for doing exactly what its name suggests, giving you complete control over your system's fans, including your CPU and GPU fans, plus any water cooling pumps that you may ...

A CPU's operating temperature will rise if the cooling fan breaks, dramatically increasing the chance of hardware failure. Stock modern computer CPUs use a two-part CPU cooler that features a heatsink ...

After a week with my new build I'm realizing that my fan curve settings are terrible. Bottom PWM fans are mapped to coolant temp, basically linear from 50% duty cycle @ 30 Celsius coolant to 100% duty ...

A CPU fan is more than just a fan. It is attached to CPU with power pins/wires and a sensor that tells it how fast to run. If the CPU is heating, the sensor will make the fan run faster. As such, the ...
