Low-noise fans cut down on annoyance

NMB Minebea has developed a novel range of low-noise fans.

In almost all new developments for home and office applications the noise of the fan can cause a great deal of annoyance.

Ever higher packing densities and higher processor speeds result in high thermal losses, requiring cooling devices that would (ideally) generate no noise.

Unfortunately the noise of a fan is traditionally linked to its speed performance.

But now NMB Minebea has developed special low-noise fans in industry-standard 60 x 60 and 92 x 92mm sizes.

The casing of the fan has tiny slots that damp the noise generated from the edges of the impeller.

The difference between a standard fan and the low noise counterpart is almost 4dB.

Another effect is that the pressure stability is much better.

The fan's characteristic is similar to a diagonal fan with its large working range.
