Key Features of Nanoflux Bearing (NFB)
The Nano-technology composite ensures lowest abrasion and extreme durability (MTTF 100’000 hours). Compared to other Magnetic bearings this technology allows the impeller to be detached and thus the fan blades can be cleaned easily.

Nanoflux Bearing (NFB) compared to sleeve and ball bearings
Even though conventional sleeve and ball bearings currently dominate the fan market however both have their disadvantages. While sleeve bearings have very low noise emissions and are very cost effective, they tend to leak oil; once the oil has dissipated the fan can no longer operate. Ball bearings, on the other hand, while providing longer operating life are costlier, noisier and are prone to damage.
GELID’s Nanoflux bearing uses magnetic flux to limit contact and friction between the bearing and the shaft. High precision self-lubricated material eliminates oil leakage. The result is a ultra quiet long life bearing.

PWM Control & LED Light

Both models include a PWM Control which keeps the fan silent if no additional cooling is necessary but increases the fan speed whenever additional cooling is required. To give the fans a unique color, a white LED light is embedded into the 120mm green WING 12 PL fan.
