Replacement CPU Fan for Acer Aspire S5-391

This new cooling fan is designed specifically for the Acer Aspire S5 S5-391 notebook. It serves as a direct replacement for the original processor fan to maintain proper thermal management. The component is intended for technicians or owners repairing a faulty or noisy cooling assembly in this exact laptop model. It is not suitable for other Acer series or different manufacturer chassis.

Restores Original Cooling Performance

Installing this fan replaces a worn or failed unit to restore the intended airflow over the CPU heatsink.

Questions about this item

Will the fan bearing need lubrication or replacement over time?

The fan is a sealed unit with no user-serviceable bearings; if noise or vibration develops, the entire fan is replaced rather than lubricated.

What thermal limit stops the fan from spinning faster under sustained load?

The fan speed is capped by the laptop's embedded controller firmware, which sets a maximum RPM based on the S5-391 thermal profile.
