Cooltek Silent Fan 4010 Computer case 4 cm Black, White

With the Silent Fan Series, we present the next step in the evolution of low-noise Cooltek fans. A revised fan blade design and the use of extremely durable Rifle-bearings are the outstanding features of this newly developed silent fan series.The Cooltek Silent fans are ideal silent case fan for budget conscious users who are not willing to make compromises in quality. This 40 mm model of the Silent Fan series rotates at 4,000 rpm max., producing an airflow rate of approximately 12.8 m³/h. The fan is particularly silent running with a noise level of just 12.8 dB(A). Included in the package are a set of fan screws, and practical silicone washers for the decoupled installation of the fan. The starting voltage of the fan is about 7 volts; the speed can be adjusted at any time by means of a corresponding fan controller or an optional adapter cable. The frame of the 40 mm Silent Fan is particularly stable and gives the fan a high stiffness. In combination with the high-quality bearings, the fan produces therefore with very little vibration. Apart from the particularly high life expectancy the fan offers a very attractive price-performance-ratio. The fan can be connected directly to the motherboard (3-pin molex connector). The monitoring of the speed through the motherboard or appropriate monitoring software is possible.
