The GELID Solutions Wing series of fan uses a Nanoflux bearing (NFB), which is better known in the enthusiast community as an electromagnitic fan. By using a magnetic design, the fan is able to run friction-free and has no motor noise since no brushes are spinning inside the fan. This means that the fan will never have bearings that break down and begin to squeal as the fan ages over the years.

Quote: "The Wing 8 uses patented nanoflux bearings inside their fan. Nanoflux bearings use a magnetic design and are able to run friction-free, extremely silent and could last for a very long time. The fan comes with a 5 year warranty, but I think that with the use of this technology it could last much longer. The Wing 8 is also UV responsive. Legit Reviews made a 39-second video showing the blue UV properties of our test fan. It does produce a nice blue color as it advertises on the package..."
