My only gripe but I could almost fry eggs on this thing. The Enermax 431 I took back never ran this hot.. okay I imagine its the lame fan speeds of the PSU. I've notice they run a good 1000rpms slower than the Enermax. Ive never seen the fan go over 1825rpm where the Enermax would go as high as 2800rpm. Other than that, the rails are a lot more stable.
