OEM Industries AB7005hX-Q0B replacement fan

This OEM Industries AB7005hX-Q0B is a 5 V hydraulic-bearing cooling fan built for specific Lenovo notebook models. It serves owners of M40, M40-70A, M40-70, M40-35A and S40-70 laptops who need a direct replacement for a worn or noisy original unit.

4-pin hydraulic bearing with 5 V operation

The hydraulic bearing offers quieter running and longer life than sleeve alternatives while the 4-pin connector enables PWM speed control from the system board. It fits the listed chassis without modification but will not suit laptops outside the M40 and S40-70 families.

5 V 4-pin connector decides compatibility

The single specification that determines fit is the 5 V 4-pin power connector matched to the ADDA AB7005hX-Q0B model code. Buyers must verify their existing fan carries the same voltage, pin count and model number before ordering.

Questions about this item

Will the AB7005hX-Q0B fit the Lenovo M40-35A motherboard header without an adapter?

The fan uses a 4-pin connector designed for the Lenovo M40, M40-70A, M40-70, M40-35A and S40-70 models, so it plugs directly into the matching header.

How can I confirm the hydraulic bearing is spinning correctly after installation?

Enter the BIOS hardware monitor or use Lenovo Vantage to verify the CPU fan RPM reads a steady value above zero and no fan-error warning appears.

Does the package include mounting screws or thermal paste for the Lenovo S40-70 heatsink?

The item is supplied as a fan only; mounting hardware and thermal compound are not included and must be sourced separately.
