I had actually come with LED fans never anything at the hat, but I am with the Lian-Li PCQ-08 Mini-ITX enclosure on the taste ... Probably these fans are not built on the highest pressure, but the fact is that it is very quiet at rated speed. I had initially connected him directly to the fan controller on the motherboard, but then realized that the noise level does not change, whether it is now turned down, or "full speed" turns. Visually nice to look at, very quiet and low, therefore 5 Stars.
