Summary: 01MAY14: Purchased four of these fans for my case to help with cooling and take advantage of my PWM slots on my mother board. I'm running the fx-8350 at 4.8GHZ which is kept in check with a H100I so there is a lot of heat to get out of the case. So far I'm impressed with these fans. At full bore they are just as noisy as the NZXT fans I had in, but at 76-77CFM these fans have done a great job in moving the air.
Summary: Pros: Well built Moves a lot of air (even at low speeds) Fairly quiet at low speeds PWM Comes with vibration reduction pads Cons: Noisy at high speeds Other notes: Is not the same fan that comes with the Cooler Master RR-T612-20PK-R1
Summary: I choose the fan as a replacement for a fan in my Thermaltake case. But had to return it because the fan did not have a Molex connector. Sure wish they would have shown me a picture of the connector, would have made my decision easier. On the plus side, the vendor and Amazon made the return process painless.
Summary: My PC is mounted in a semi, therefore I face some extreme ambient thermal conditions. I ordered 10 of these, 2 as pull fans for my 240L and the other 8 as case fans in my Thor V2. Using fanXpert2, I'm able to idle the 4 side fans and the pull fans at 575rpm,Silent! The other 4 don't even power up 'til I hit 60 C, and then only run at 800-900rpm.
