Noiseblocker is passionate about extremely quiet fans. Especially the multiframe models with an innovative housing shape and suspension represent the company\'s flagship products. With the BlackSilent series, Noiseblocker is expanding its range to include particularly small fans. These are enjoying growing popularity again due to their use in compact mini and HTPCs and hard drive housings.The limited delivery volume of these small fans below 80mm is, however, often increased by comparatively high speeds, which results in considerable noise pollution. Noiseblocker has tackled this problem and designed a number of small and extremely quiet models. This means that the HTPC in the living room no longer interferes with enjoying a movie.Externally, the series features a black frame with transparent blue fan blades. The XR2 model is a 60mm rotor in the Silent Edition. The speed is therefore only 2,200 rpm, which results in a very low volume of 15 dB (A).Four silicone pins are provided to attach the fan. This also reduces the volume by preventing vibrations from being transmitted to the housing. The connection cable was neatly sheathed and provided with a 3-pin connector.Technical details:- Dimensions: 60 x 60 x 25 mm- Weight: 60 g- Material: Plastic- Volume: 15 dB (A)- Speed: 2,200 rpm- Airflow: 24 m / h- Starting voltage: 6 V- Voltage: 12V- Power consumption: 0.9 W- Connection: 3-pin- Life expectancy: 30,000 hours- Warranty: 3 years
