Compatible ThinkPad models

This replacement fan fits Lenovo ThinkPad E420, E520, E425 and E525 laptops. It is a new component designed to restore original cooling performance in those specific chassis. The part addresses worn or noisy factory coolers in the listed machines.

Sustained thermal behaviour

Under continuous load the fan maintains steady airflow to keep the processor within its thermal envelope. It prevents the throttling that occurs when an aged cooler can no longer move enough heat during long work sessions. The unit is built for the thermal demands of the supported ThinkPad platforms.

Questions about this item

How much noise and heat should I expect from this fan when the ThinkPad E420 runs all day?

The fan is a direct replacement for the original cooler in the E420, E520, E425 and E525, so noise and thermal output match the factory specifications for those models.

What else must I already have inside the laptop for this cooler to fit and work?

You need the existing heatsink mounting points and the 4‑pin fan header on the motherboard used in the E420, E520, E425 and E525.
