Compatible ThinkPad Models

This replacement CPU cooling fan fits Lenovo ThinkPad X240, X240S, X250, X240I and X260 laptops. It matches part numbers 00UP171, 00UP172 and EF50050S1-C590-S9A. The unit is supplied new and tested individually before dispatch. Buyers with other ThinkPad series should verify their original part number first.

Cooling Capacity and Limits

The fan restores factory airflow for the listed ultraportable chassis, keeping the processor within thermal limits during typical office workloads. Under sustained heavy compute the single-fan design will reach its thermal ceiling faster than larger dual-fan systems. It is not intended for workstation-class loads or overclocked configurations.

Upgrade Context and Fit

This part replaces a worn, noisy or failed original cooler in the supported X-series models. The jump is worthwhile when temperatures climb or the original fan develops bearing rattle. It will not fit ThinkPad T, L, P or Yoga lines, nor any non-Lenovo ultrabook. Always compare the connector and screw holes with the removed unit before installation.

Questions about this item

Will this cooler fan fit the heatsink mounting points on my ThinkPad X250 without modification?

This fan is listed as compatible with the X250 and matches part numbers 00UP171 and 00UP172, so it should align with the original mounting holes.

How can I verify the EF50050S1-C590-S9A fan is spinning correctly after I install it?

Enter the BIOS hardware monitor or use Lenovo Vantage to confirm the fan RPM reads above zero and rises under load.

Does the package include thermal paste or mounting screws, or do I need to supply them?

The box contains only the fan itself; thermal compound and any replacement screws must be purchased separately.
