120mm PWM 4-Pin Case/CPU Fan
The Asus ROG Z790 BIOS requires a valid tachometer signal from the CPU_FAN header to bypass the POST safety check. A replacement PWM fan restores this signal if the original fan has suffered a motor failure or a broken sense wire. Using a standard 4-pin PWM fan ensures compatibility with the motherboard's speed control logic and clears the 'CPU Fan Speed Detection Error'.
