The Static Booster 14 is a special designed adapter for use with Prolimatech"s Ultra Sleek Vortex 14. It is meant to direct and focus the airflow, thereby increasing the static pressure provided by the fan. In addition, the Static Booster helps to absorb fan vibrations, further reducing noise. The Static Booster is 140x140x10mm. Installation of the Static Booster on to an Ultra Sleek Vortex 14 Fan will convert the fan from 15mm to 25mm in thickness. For use with Prolimatech"s Ultra Sleek Vortex 14 Fan.
