[Cooling fan] How can I check if my 4-pin connector supports PWM function?

Check the motherboard or device manual

If labeled as "CPU_FAN (PWM)" or "SYS_FAN (PWM)," it usually supports PWM.

Look at the pin layout

A standard 4-pin PWM header uses the 4th pin as the PWM control signal (often with a blue wire).

Check BIOS or software settings

Some systems allow switching between DC Mode and PWM Mode; if available, it indicates PWM support.

Test fan speed behavior

f the fan slows down at low temperature and speeds up at high temperature automatically, PWM control is supported.
