You need to read the fine print and reviews about capacity. I'm using it to power a pair of 140mm fans for a cooling station under my router. It suites my needs fine because I am using it at about 30% on the dial to provide cooling which is absolutely silent. Antec Tranquil fans are high quality and only brand I trust around for a while that truly makes a silent fan. The speed control is quality and sweeps almost 360 degrees with a off position...real nice. My fans come on at about 15-20% of travel. If I turn it up all the way, the fans start to faulter, one fan works okay, but only comes up to about 80% of max capacity. With both fans, I can get up to 50% of travel, which is fine for my application. Specs do warn that this is not for 12V USB fans. Switch has a bit of a radio shack look to it, but my computer is half old school anyway, I think its fine.
