Silverstone SST-AP81 Air Penetrator - 80mm [SST-AP81 ]

After launch of the groundbreaking computer fan Air Penetrator AP121 in 2010, the Silverstone developers were working on a new milestone in terms of design, which further refines the channeling cooling concept. Typical case fans usually produce - no matter how quiet they turn - clearly audible noise when they are installed as Zuluftgehäuselüfter. Higher tones are the result of air turbulence generated between the fan blades and Zuluftgrill of the housing.

The AP81, however, uses as the AP123 fan blades with three unique shapes and sizes to create a non-uniform air circulation. This design can be a little louder when the fan rotates autonomously; However, if it is installed as a case fan, the sound frequency is reduced by up to 66%. In addition to the noise reduction, the unique design of the fan blades is also the production of high air flow and static pressure, whereby great benefit is achieved. Coupled with the same channeling grill that was made famous by the AP121, the AP81 is one of the best Computerzuluftlüfter on the market.

The standard rotation speed of the AP81 with 80 mm frame width is 3000 U / min, 30 dB (A) are generated. Thanks to low starting voltage of 4.5 volts, the speed is throttled again, so that even a silent operation is possible. A Molex adapter to power through the AC adapter is included.
