Compatible BenQ S43 laptop CPU cooler

This replacement cooler fits the BenQ S43 laptop and installs directly in place of the original fan assembly. It is intended for owners who need to restore cooling performance after a bearing failure or blocked heatsink. The part matches the factory mounting points and connector orientation. Buyers whose laptops use a different internal layout or fan connector will need a different component.

Normal thermal behaviour and power draw

The fan spins up under load to move air across the CPU heatsink and returns to a lower speed during light tasks. Power consumption stays within the laptop’s original thermal design envelope. Acoustic output rises with RPM but remains comparable to the stock cooler. No liquid loop, radiator or external power adapter is involved.
