Using for gaming. Extremely powerful machine, works real well. No problems. Phenomenal CPU & GPU temperatures with all fans set on low. Very quiet considering the amount of fans. 3x 200mm, 3x 120mm, 1x 140mm case NZXT case fans. Dual fans on each video card and 2x 120mm fans for the Corsair H100i radiator. A grand total of 13 fans. The noisiest part of this setup is the H100i pump, which makes a light clicking sound. This is due to the 12v PSU supplying too much power to the pump, but hopefully Corsair will release new firmware or a new connector in the near future. Posting 100+ FPS on most games. Extremely fast loading times thanks to the Samsung 840 Pro SSD. Scored a 7.7/7.9 in Windows Experience Index. Graphics/Gaming Graphics/Primary Hard Disk scored 7.9. Processor 7.7, Memory 7.8. I plan on overclocking the CPU to 4.8-5 GHz in the near future.
