Replacement fan kit for Acer Aspire S7

This kit provides two replacement cooling fans sized at 30mm and 40mm for the Acer Aspire S7 series, specifically the 391 and 392 models. It is intended for owners whose original fans have failed or become noisy. Each unit is tested before dispatch to confirm it spins correctly.

Thermals and acoustics in daily use

The two fans work together to move air through the laptop's existing heatsink assembly, keeping processor temperatures in check during typical office tasks and media playback. Because the fans are direct replacements, they maintain the original acoustic profile without adding extra vibration or whine.

Behaviour under sustained load

During extended workloads the dual-fan arrangement continues to draw heat away from the CPU and GPU, helping to prevent thermal throttling over long sessions. The 9-month warranty reflects the supplier's confidence in durability under continuous operation. Buyers needing a complete cooling-pad accessory rather than an internal fan replacement should look elsewhere.

Questions about this item

How do I install the 30mm and 40mm fans in my Acer Aspire S7-391, and which step is often missed?

Remove the bottom case, disconnect the old fan cables, fit the 30mm and 40mm units into their original mounts, reconnect both cables securely, then reassemble; the step most often missed is plugging in the second fan connector.

What maintenance will the Forcecon, ADDA, Sunon or Kipo fans need over time?

Clean dust from the blades and vents every few months with compressed air; the sleeve bearings are sealed, so no lubrication is required, but replace the unit if noise or vibration increases.

At what point does the dual-fan assembly hit its thermal limit during sustained loads?

The pair moves air at the rated 30mm and 40mm dimensions; under continuous heavy load the limit that appears first is the laptop’s own chassis heat capacity, not the fans’ airflow.
