OEM Industries MCF-W09AM05 5V Blower Fan

This OEM Industries MCF-W09AM05 is a blower-style fan designed for notebook and laptop CPU cooling. It operates at 5 V with a 0.35 A draw and connects through a standard three-pin header. The unit is supplied as a fan only in a black finish.

Suits 5 V three-pin notebook coolers.

This cooler suits repairs or upgrades where the original blower uses a 5 V three-pin connection. Builders needing a different voltage, a four-pin PWM header or a proprietary manufacturer connector cannot use this part. Desktop systems and liquid-cooling loops are also outside its intended scope.

5 V 0.35 A three-pin power specification

The deciding specification is the 5 V 0.35 A rating on a three-pin connector. Match these exact electrical values to the device header before purchase; a mismatch will prevent the fan from running or risk damage. No other voltage or pin configuration is supported by this model.

Questions about this item

Will the 3-pin connector on this MCF-W09AM05 blower fan work with the 4-pin header on my older laptop motherboard?

The fan uses a 3-pin power connector that fits standard 3-pin headers; it will physically connect to a 4-pin header but PWM control will not be available.

How can I confirm the blower is spinning at the correct speed after installing it in my notebook?

Check the BIOS hardware monitor or a fan-speed utility; the fan should report a speed consistent with a 5 V, 0.35 A blower under load.

Does the package include mounting screws or thermal paste for the laptop heatsink, or must I buy them separately?

The box contains only the MCF-W09AM05 blower fan itself; mounting hardware and thermal compound are not included and must be sourced separately.
