PWM CPU Cooling Fan
The 'CPU Fan Error' is a hardware-level safety interrupt triggered when the motherboard logic fails to detect a rotation signal (RPM) from the CPU cooler. This is typically caused by a failed fan motor, a broken tachometer wire, or an internal short in the fan's Hall-effect sensor. Replacing the fan restores the closed-loop communication required for the BIOS to confirm active cooling and allow the system to boot.
