Low engine temperature - 4 times the service life: A 10 Degree C lower motor temperature doubles the lifetime. Because of the low coil temperature, the life span of the Bionix gaming fans is four times as long, so we extend the warranty to 10 years. Quiet 3-phase motor: The extremely quiet operation of the 3-phase motor guarantees long gaming without disturbing noises. 200 to 1800 rpm: With a wide speed range and the PWM Sharing Technology (PST), the fan speed of the Bionix F120 can be controlled synchronously with all other fans. This reduces the noise to the minimum and at the same time guarantees the highest cooling performance. Optimized fan design: We have further optimized the design of the fan blades in order to obtain a stronger air flow with less noise. This guarantees high air pressure and a very efficient ventilation for your gaming housing. Improved bearings: Thanks to a new combination of alloy/lubricant developed in Germany, friction within the bearing is reduced and greater efficiency is achieved. In this way, less heat develops, there is less bearing noise and you can enjoy a longer life of your cooler.
