Alienware M17 replacement fan

This 4-wire case fan is built as a direct replacement for the Alienware M17 laptop. It matches the original ALWH-B2475020G00003 and AVC S090507W part numbers so the system recognises it immediately. Installers can swap the unit without adapter cables or firmware changes.

OEM-spec cooling for a single chassis

The fan delivers the airflow and speed profile Dell specified for this 17-inch model, keeping CPU and GPU thermals within factory limits during typical loads. It is not designed for desktop cases, other laptop series or custom liquid-cooling loops where a different pressure curve or connector would be required.

Questions about this item

Will the AD4205HX-L03 YB4 fan fit alongside the original heatsink in my Alienware M17?

The AD4205HX-L03 YB4 is built for the Alienware M17 chassis, so it aligns with the existing mounting points and clears the factory heatsink without modification.

How can I confirm the AVC S090507W fan is spinning correctly after installation?

Boot the laptop and listen for steady airflow from the exhaust vent; fan speed will also appear in Alienware Command Center or the BIOS hardware monitor.
