With the Silent Fan LED Series, we present the next step in the evolution of low-noise Cooltek fans with a particularly striking illumination.
A revised fan blade design and the use of extremely durable Rifle-bearings are the outstanding features of this newly developed LED fan series. The Cooltek Silent LED fans are ideal silent case fan for casemodding fans who are not willing to make compromises in quality.

This 140 mm model of the Silent Fan LED series rotates at 900 rpm max, producing an airflow rate of approximately 108.4 m³/h. The fan is particularly silent running with a noise level of just 13.9 dB(A). Included in the package are a set of fan screws, and practical silicone washers for the decoupled installation of the fan.

The fan is equipped with four red-lit LED’s mounted to the frame. Frame and blades are made of semi-transparent material, the rotor is held in red.

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.

Apart from the attractive LED lightning, the fan offers a very attractive price-performance-ratio and a particularly high life expectancy.

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.
