Replacement CPU Fan for IdeaCentre B520

This replacement CPU cooling fan fits the Lenovo IdeaCentre B520 all-in-one desktop identified as Type 7745 and model B520E. It matches part numbers KUC1012D, BASA1825R2U and BASB1825R2U for direct compatibility. The unit is supplied new and tested before dispatch.

Upgrade from a worn or noisy original fan

Install this fan when the factory cooler has become loud, runs at high speed constantly or has stopped spinning. The swap restores the thermal performance the system was designed for and is worth doing before overheating causes instability or component stress. No other hardware changes are required.

Steady airflow during extended workloads

Under sustained load the fan maintains consistent rotational speed to keep internal temperatures stable rather than spiking. Each unit is individually tested to confirm 100 percent operation before shipping. The manufacturer may supply the fan from Forcecon, ADDA, Sunon, Kipo or equivalent sources depending on stock.

Questions about this item

Does this fan fit the Lenovo IdeaCentre B520 type 7745 chassis?

The listing matches Lenovo AIO IdeaCentre B520 type 7745 and part numbers KUC1012D, BASA1825R2U and BASB1825R2U, so it is made for that chassis.

What is the tricky step when swapping the original fan for this one?

Disconnect the old fan cable from the motherboard header, then route the new cable exactly the same way so it clears the heatsink and does not snag on the case edge.

When will the replacement fan need attention again?

The unit carries a 9-month warranty; after that period plan to re-check for dust build-up or bearing noise and replace if airflow drops.
