This is truly a premium product. I think it is impossible to find and buy a fan for a computer case, for a power supply unit that will be better than this. Even when you see how this product is packaged, you realize that every dollar you pay for it pays off. It even seems to me that this fan is not expensive. It is very high quality, beautiful, with a unique color. The bearing technology is advanced, several very useful cables and mounts are included. And most importantly, the fan is quiet and very efficient. I replaced it with the factory fan of my desktop computer power supply. I used the Low-Noise Adapter (L.N.A.) cable from the package to lower the rpm to 900-1000 per minute and the fan is almost inaudible. I am truly very satisfied.
