Replacement CPU fan for Acer ultrabooks

This new CPU fan is built to replace the original cooler in Acer S3-391 and S3-951 ultrabooks. It matches the MS2346 part specification so the system recognises the hardware and regulates speed correctly. Installers can fit it without modifying the chassis or wiring.

Restores factory cooling performance

Swapping the worn fan for this unit brings back the airflow and acoustic profile the laptop shipped with. Thermal throttling caused by a failing bearing or clogged heatsink is eliminated once the replacement spins up. No extra brackets, cables or software are included because the original mounting points and connector are reused.

Questions about this item

Will the fan bearing need replacement on the Acer S3-391 CPU fan?

The sleeve bearing is designed for the fan's service life; no user-replaceable bearing is specified for this ultrabook cooler.

What thermal limit appears first during sustained load on the Acer S3-951 CPU fan?

The ultrabook chassis reaches its thermal ceiling before the fan hits maximum RPM, so skin-temperature limits throttle the CPU first.
