Replacement CPU cooling fan for Lenovo ThinkPad E531, E431, E440 and E540 laptops
This new original CPU cooler fits Lenovo ThinkPad models E531 E431 E440 and E540. It restores factory cooling performance for owners of those specific laptops. The part number BATA0710R5H P005 matches the original equipment specification. Buyers with other ThinkPad series or different laptop brands cannot use this fan.
The cooler uses the stock screw pattern and connector so no adapters or modifications are required. Technicians should clean old thermal compound from the heatsink before fitting the new unit. A common issue is forgetting to reconnect the fan header or pinching the cable during reassembly. Verify the fan spins freely after installation to avoid overheating.
