Super fans, for the unbeatable price of 5.99, we can say nothing with it is still an adapter on a 4-pin Molex connector. The fans blow air properly and are fairly quiet, the only thing I would complain about the red LED's that light up are so weak that you can hardly see. For me, not a problem that I have 2 red cold cathode in it, who so but will illuminate his PC is operated wrong here.
