Replacement CPU Fan for Samsung NP300 NP270 Series

This replacement CPU cooler fits Samsung NP300E5E, NP300E5V, NP300E4E, NP300E4V, NP275E5E, NP270E5E, NP270E5V, NP270E4V and NP275E4V laptops. It matches part numbers MF75090V1-C230-G9A, BA31-00138A and KSB0705HA-CJ28. The unit is supplied new and tested before dispatch.

Single Fan Unit Shipped Without Mounting Extras

The package contains only the fan assembly; no screws, thermal pads or cables are included. Buyers must reuse the original fasteners and thermal interface material from the old cooler. Manufacturers such as Forcecon, ADDA, Sunon or Kipo may be used depending on stock, so the exact label can differ.

Direct Swap Installation

Installation is a direct swap once the laptop is opened, but the supplier advises comparing the replacement to the original fan before fitting. Connector orientation and screw-hole alignment vary between revisions, so a careful visual check prevents ordering the wrong variant.

Questions about this item

How often will the MF75090V1-C230-G9A fan need replacement under normal use?

The fan is tested individually before shipping and covered by a 9-month warranty, so typical replacement would only be needed if bearing noise or airflow drops after extended daily operation.

What is the first limit reached when the KSB0705HA-CJ28 runs continuously in a Samsung NP300E5E?

The first limit is usually thermal — the laptop chassis itself throttles before the fan reaches its maximum rated speed, so sustained loads are capped by system cooling capacity.

How much noise and heat does the BA31-00138A add when running all day?

It operates at the same acoustic level as the original factory fan and adds no measurable heat; power draw is negligible compared to the CPU and GPU it cools.
