Compatible ThinkPad Models

This replacement cooling fan fits Lenovo ThinkPad E330, L330 and E335 laptops. It matches part number KSB0705HB-BK2S for direct installation. Buyers who need a cooler for a different ThinkPad series or a universal pad should look elsewhere.

Sustained Cooling Behaviour

The fan is tested before shipping to confirm it spins up and moves air steadily. It replaces a worn or noisy original unit so the CPU can maintain its speed during long sessions. No thermal benchmarks or airflow figures are supplied by the manufacturer.

Critical Part Number

The only specification that guarantees fit is the KSB0705HB-BK2S part number printed on your existing fan. Verify that code against the product photos before ordering. An incorrect match will not mount or connect properly.
