Replacement CPU Cooling Fan

This new DBTLAP cooling fan replaces the CPU cooler in Lenovo ThinkPad E431, E531, E440 and E540 laptops. It operates at 5 V and draws 2.25 W. The package includes one fan unit tested before shipping. Match the part numbers MF75090V1-C320-S9A, BATA0710R5H or P007 to confirm fit.

For ThinkPad E-Series Owners

This part suits owners of the listed ThinkPad models who need to replace a worn or noisy CPU fan. It is not for other laptop brands or different ThinkPad series. Buyers who cannot verify their exact part number against the three references above should look elsewhere.

Critical Part-Number Match

The single specification that decides fit is the exact part number: MF75090V1-C320-S9A, BATA0710R5H or P007. If your original fan carries a different code, this cooler will not be compatible.

Questions about this item

How do I install the MF75090V1-C320-S9A fan in my ThinkPad E440, and what step do people often miss?

Remove the bottom cover, disconnect the old fan cable, fit the new unit, then reconnect the cable and test before reattaching the cover; the missed step is forgetting to verify the fan spins at 5V 2.25W before final assembly

What maintenance will this BATA0710R5H cooler need later?

Clean dust from the heatsink fins and fan blades every few months with compressed air; the sleeve bearing is not user-lubricated, so replace the whole unit if noise or vibration appears

What limit shows up first when this 5V 2.25W fan runs continuously under heavy load?

The 2.25W power ceiling caps maximum airflow, so sustained high CPU temperatures will hit thermal throttling before the fan can increase speed further
