If you want to use the computer USB interface to power the case fan, please choose this cable. Or if you want to DIY the chassis fan in a laptop cooling fan, please use this cable. This cable is a 4-pin Molex interface, as only two wires are needed for USB power so only two of them are used.

Review: Works Great, but will not power multi fans at full flow. - 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.
Review: Effective and excellent for its purpose - They did exactly what I hoped they would -allow me to utilize quiet case fans in place of my desktop fans which are too loud, and give me complete control over the fan speed. Very pleased with this purchase.
