I haven’t seen many of these Nanoflux bearing powered fans, most fans are either sleeve of ball bearing supported fans. 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 an ultra quiet long life bearing.
Most UV Reactive items react well to blue lights. Probably better than using a regular UV light. But these fans have no reaction to Blue lights whatsoever. We tried this because we were somewhat disappointed by the glow coming from the blades. In the first photo you can see the blades brightly lit, but as soon as you move the UV CCFL a bit further away from the fan, the glowing effect will be reduced and they won’t look as cool anymore. Normally this could be countered by adding a blue CCFL somewhere near the fan to make them glow even better. But as I said, these fans won’t work with regular blue lighting.
So the glowy bit is somewhat of a gimmick and it’s not as impressive as some of the other UV reactive fans that I have tried, but the included bits and pieces make these fans a complete package. The fan noise with the fans running at full speed is not dead silent, but these are not designed to go head to head with fans from Noctua for example. But they are pretty silent as soon as you use the included fan speed controller and they provide enough CFM, even when they are powered down. So you would have more than sufficient cooling when you get a couple of these in your computer casing.
