The Nanoxia SPECIAL N.N.V. 800. Equipped with a 3-pin Molex connection for speed control. The fan rotates with just 800 rpm and is therefore absolutely inaudible. Even at full speed, it produces just 6.1 dB (A) *. The fan achieves a maximum static air pressure of 0.35 mm-H 2 O, or an air throughput of 46.2 m 3/h.
Welcome to the "fan" club of a real revolution - with an amazing story: for some time already the much smaller ancestors of this airy sensation turned their rounds in seat heatings, until Nanoxia recognizes their special talent, takes them from the street and now as a SPECIAL N.N.V. Fan series directly in the PC area. With a newly optimized principle and a corresponding chassis, this exceptionally cool special unit, under the name of German Silent Force, is now launching its innovative service.
Thanks to the patented technology, Nanoxia offers the first practically vibration-free PC fan in the world. And this works as follows: Made of two mutually decoupled frames, the outer fan frame provides mounting points for the fan in the case or on a CPU cooler - while the inner fan frame (decoupled with four plastic dampers from the fan frame) contains the rotor and the fan motor.
Also part of it is already proven FDB-bearing, which is very robust and long-lasting. Special feature: extremely low mechanical wear. This keeps the fan continuously quiet throughout its lifetime.
Runs, runs and runs ... typical of the SPECIAL N.N.V. Series. Rotor and fan blades are optimally balanced. In conjunction with the wear-resistant Fluid Dynamic Bearing, the fan guarantees a particularly long service life.
Perfect control including: The motor of the fan receives its PWM signal via a 4-pin connection on the mainboard. The fan electronics evaluate the signal and regulate the motor power permanently and automatically. The PWM control of the Special N.N.V. Fans astonished with a very linear control range, so that speed changes are hardly perceptible.
The SPECIAL N.N.V. 800 is the ideal fan when absolutely noiseless air circulation is desired.
* The sound pressure was measured according to CNS 8753 from a distance of 1 meter at 12 volts in a low-reflection room.
