The SilverStone Air Slimmer 140 is only 15.5 mm thick making it an ideal choice for scenarios where available space is limited. The SilverStone Air Slimmer 140 is available in both ARGB and non-ARGB models and uses a scimitar fan blade design combined with SilverStone’s Shark Force fan blade pattern to both guide air and reduce noise. Using an all-copper fluid-dynamic bearing motor it is capable of up to 1700 RPM and can produce airflow up to 82 CFM with a static pressure of 2mmH₂O while reaching a noise level of ~ 33 dBA.

The SilverStone Air Slimmer 140 can support slower fan speeds, all the way down to 0 RPM thus providing further options for silent cooling, as long as the motherboard supports it. Both versions are currently available on Amazon.

Features (per SilverStone):

  • 15.5mm thick slim fan, ideal fan for space-limited builds
  • Distinctive “Shark Force” fan blade design with high air pressure enables quick heat dissipation through radiators or heatsinks
  • Wide 0~1,700 RPM speed range via PWM control
  • Modular cable design simplifies connection and management of cables
  • Engineered to also be an effective exhaust fan for transporting large volume of heat out of most systems
  • All-copper Fluid Dynamic Bearing (FDB) offers superior performance with long lifespan.

Per SilverStone:

“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.”

As a child of the 70’s I was part of the many who became enthralled by the video arcade invasion of the 1980’s. Saving money from various odd jobs I purchased my first computer from a friend of my dad, a used Atari 400, around 1982. Eventually it would end up being a lifelong passion of upgrading and modifying equipment that, of course, led into a career in IT support.
