It's tough to pass the deal, so bought 3x of these awesome pci slot fan cooler. They do an awesome job at cooling the ram on x79 and x299 mb's at home and also to move cooler air midway through the motherboard. My only gripe is that, the 3wires 12/g/s wires were all stuffed in the 3 pin connector and the sleeve wire were also too thick to route. The included fans are sleeve bearing and are also quiet. It also includes the 4pin fan connector controller on 3 of the packages, which is what I just needed for the 12v 172x51mm fan I mounted on the other pc from gdstime so it runs nicely at 5v, for maximum tornado effect :)
