Compared to my previous fan a real Leisetreter. If the hard drive would not run, I could probably hear my breath after switching. It is nice that one of the fairly low price also gets two of them. My old fans was such an aluminum part with two small fans that have run like crazy to 3600 revolutions per hour. Insanely! Here, since the fan-radius is twice as large as in one of the small fan, and also the drive only once takes away the surface, the area of the ventilation is much greater and the air flow rate at 1,000 rpm of the same! This lower speed, less strain on the storage and very low noise. Top! I have the fan far, so I have no knowledge about the long-term suitability. But honestly: 2 such fan for around 12 euros. If then in a few years is loud, you just installed the second and it's quiet again. ;) Highly recommended!
