Check your existing fan before ordering

Verify that the original cooler matches the 40 mm square frame and 15 mm thickness. Confirm the connector is a four-pin PWM header with identical pinout. Ensure the mounting screw pattern aligns with the replacement unit. Buyers needing a different voltage, connector type or frame size cannot use this part.
