Replacement CPU Cooling Fan for ASUS Laptops

This DC 5V, 2.25W cooling fan is designed as a direct replacement for the MF75120V1-C251-S9A radiator assembly found in compatible ASUS models. It addresses overheating or fan failure in portable workstations that require this specific part number. The component restores original thermal performance for supported notebook configurations.

Low-Power Thermal Management for Notebook Repair

Operating at 5 volts and drawing 2.25 watts, the fan maintains modest power consumption suited to laptop thermal envelopes. It is intended for the ZX50J, GL552 and GL552JX series where the MF75120V1-C251-S9A designation applies. Builders working on unrelated chassis or requiring different voltage specs should source the correct alternative.

Questions about this item

How do I install the MF75120V1-C251-S9A fan in an ASUS GL552 laptop and which step is often missed?

Remove the bottom panel, disconnect the old fan cable, fit the new fan into the heatsink bracket, reconnect the 3-pin DC5V connector, then reapply thermal paste on the CPU die — skipping the paste causes overheating.

What maintenance will the MF75120V1-C251-S9A cooling fan need after fitting?

Clean dust from the radiator fins every 6–12 months using compressed air; the sleeve bearing is not user-serviceable, so replace the whole unit if noise or vibration appears.
