Replacement CPU Fan For Laptop Cooling

The DBTLAP EF50040S1-1C010-S9A is a direct replacement CPU cooling fan built for specific laptop models. It operates on DC5V power with a 2.25W rating and uses a 4PIN connector for motherboard control. Buyers who need a different voltage, pin count or form factor cannot use this part.

Straightforward Swap With Visual Verification

Installation involves opening the laptop chassis, disconnecting the old fan and fitting this unit into the same mounting points using the existing screw holes. The 4PIN plug must align with the motherboard header. The most common error is ordering without comparing the part number and photos to the original component, leading to connector or dimension mismatches.

Limited To Exact Part-Number Compatibility

This fan only works in laptops that list the EF50040S1-1C010-S9A, SPS-L52034-001 or DC28000N6S0 part numbers in their service manual. It does not support universal fitment across brands or series. Builders who want a generic cooler or a higher-airflow upgrade for a different model must look elsewhere.
