Replacement Cooling Fan for FCN FMMJ Laptops
This DC5V 4-pin cooling fan is a direct replacement part for FCN FMMJ laptops using part number FCN9908091649. It is sold new and intended for owners who need to swap a worn or noisy original fan. The package contains one tested fan unit only. Buyers who need a full cooling pad with a USB-powered base should look elsewhere.
4-Pin DC5V Power Interface Limits
The fan connects via a 4-pin header and runs on 5 volts DC supplied by the laptop motherboard. Speed control and monitoring depend entirely on the host system's fan controller. No external power adapter or USB cable is included, so the part cannot operate as a standalone cooler. Builders who need a self-powered external cooler cannot use this component.
Matching Part Number FCN9908091649
Compatibility is decided by the exact part number FCN9908091649 printed on the original fan. Verify the photos and connector layout against the removed unit before ordering. If the part number differs, the fan will not fit or connect correctly. Users who cannot confirm the part number should not purchase this item.
