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 120 mm model has a 4-pin PWM connector for automatic speed control. Over a 4-pin connector of the fan motor receives a special PWM signal from the motherboard. The fan electronics evaluates the signal and regulates the power permanently according to the requirements.
The speed of the 140 mm PWM fan ranges from 600 - 1,200 rpm. The quiet-running fan generates an airflow rate from 88.4 to 115.4 m³/h at a noise level from 6.8 to 15.2 dB(A). Included in the package are a set of fan screws and practical silicone washers for the decoupled mounting of the fan.
The frame of the 140 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 monitoring & control the fan speed is carried out via the motherboard (4-pin PWM connector).
