Replacement Fan for Lenovo B40 Series

This replacement CPU cooling fan fits Lenovo B40, B40-30, B40-45, B40-70 and B40-80 laptops. It is a new component intended for owners of these specific models who need to replace a worn or noisy original cooler. Each unit is tested before shipping to confirm it operates correctly.

Single Fan Unit Shipped

The package includes one fan only, sourced from manufacturers such as Forcecon, ADDA, Sunon or Kipo depending on stock. No mounting screws, thermal paste or control software are supplied, so you must reuse existing hardware from the old assembly. A nine-month warranty covers the part itself.

Verify Exact Model Before Ordering

Buyers should compare the product photos with their current fan to confirm the connector and bracket layout match. This item is not suitable for laptops outside the listed B40 family or for users needing a complete cooling pad with a built-in stand. Contact the seller if you are uncertain about compatibility.

Questions about this item

Does the replacement fan for the B40-30 require any periodic maintenance?

No scheduled maintenance is needed; the unit is tested before shipping and covered by a 9-month warranty.

What limits continuous operation of the cooler on a B40-70?

The single-fan design provides a fixed airflow rate, so thermal headroom is the first constraint under sustained load.

How much noise and heat does the fan add when running all day on a B40-80?

The fan runs from the laptop's 5 V USB port and produces a low, steady sound similar to the system's own cooler.
