Some plastic, a coil and a cable seem to be out of place in the high-tech world of the PC interior - where transistors are installed in billions and microscopic tracks are distributed over several layers.
Nevertheless, there are companies that show such care, meticulousness and optimism in developing this inconspicuous product category. German engineers are - how could it be otherwise - also in this field to the world top. At Noiseblocker, they have enough scope to implement their creative ideas. The result is fans for enthusiasts who are looking for the optimum and attach great importance to low noise.
The multiframe models represent the top products of Noiseblocker and therefore combine the most innovative approaches and high-quality production methods. As the name suggests, the focus was on the frame. For example, the Multiframe S series has a glass-fiber-reinforced frame with integrated structure-borne sound absorbers.
The attachment is made by four removable and completely decoupled corner pieces made of silicone. Vibrations that inevitably occur as a result of the rotation of the fan are thus practically no longer passed on to the housing. Thus, a significant noise source is turned off, after all, said vibrations stimulate the outer surfaces of the housing to resonate, which ultimately ensures the disturbing noise.
Storage technology is less spectacular at first, but it also represents a significant component for noise reduction. The elaborate NanoSLI bearing also ensures an extremely long service life (130,000 hours on average) - an essential sign of high production quality and minimal tolerances. This is also illustrated by the very long warranty period of 6 years.
The optimized revision 1.01 also has a silicone frame. This is placed between the fan frame and fan slot to additionally dampen the vibration transmission. In addition, the frame has been designed for use on radiators where, in addition to decoupling, it ensures optimum sealing. This prevents air from escaping through the minimum gap between the fan and radiator and thus can no longer contribute to cooling
This is a PWM fan that can be controlled via a 4-pin connector. The M12PS version is designed for a lower speed, which makes the fan even better qualified for silent systems. A speed range between 600 and 1,500 rpm is available, which ensures a minimum of 7 dB (A) and a maximum of 133 m³ / h.
