Slimmer in size but statistically significant

Air Slimmer 140 is a 15.5mm thick slim fan engineered to achieve maximum performance in space-limited systems

Scimitar fan blade design

The Air Slimmer 140 features 9 scimitar fan blades designed to enhance air pressure and achieve a high airflow rate. Each fan blade incorporates SilverStone's Shark Force fan blade pattern, which resembles a shark-skin surface. This pattern acts as air guides, contributing to the overall smoothing of airflow and significantly reducing audible noise.

Premium motor & bearing construction

Equipped with superior all-copper FDB and actively-cooled motor which allows Air Slimmer 140 to exhibit a low level of friction with high durability and operational efficiency.

Ideal for Small Form Factor builds
