What a waste, save time and money and get a cooler ...

Summary: Needed it to have 4-pin MOLEX, the only connectors I can't even use and the fan doesn't turn on when I hook it up to my motherboard. What a waste, save time and money and get a cooler master or something else.
Summary: This is a very quiet fan, no whining just air. I'm using it on a heatsink even though it's described as a case fan. The original fan was just to loud. You only need one motherboard header. For 1 fan, plug the single yellow wire into the pigtail plug it into your PWM motherboard header.
Pros: quiet fan for the price keeps my case cool and the vibration absorbing mounts was a nice feature moves a good amount of air from the case with low rpm my old fan would have a little over 1200 rpm and was a little noisy and this fan runs around 750 to 850 rpm and completely quiet
Summary: Nice and quiet fan, packaged well. PWM works well. Only issue was that the fan power cable was too short for my tower and I had to buy an adapter. I would imagine for mid towers and smaller this would not be a problem.
