I got myself this monster to keep my i5 2500k nice and cool, well and because it simply looks cool: D I must say that I am very impressed by the cooling capacity. I'll be in idle mode does not exceed 30 ° and the fullest full load not exceeding 50 ° - not even when I learn about tacts (4 GHz). And I have the fan control that can be installed in a slot on the back of the case, always set very weak, since he can be very noisy at high speeds. However, one should pay attention to two things: 1. The part is fucking great! I have it in a NZXT Phantom (äuse External / dp / B003WE9WQO / ref = pd_cp_computers_0) and even the fact it will be very close after the installation! 2. Do not make the mistake (as I ^^) install and only the motherboard ... The fan is screwed from behind so I could unscrew the motherboard again, but may be due to the unfavorable back of NZXT.
Due to the performance and the design and since I have no serious negative criticism, 5 star and a strong buy recommendation from me!
