THIS HEAT SHALL NOT DEFEAT ME. Ordered 4x120mm 100CFM fans + a controller, will remount for the third time in an even more heat friendly configuration. Noticed something really weird and very unsettling though.

I'm drawing 262W for 2 units + 500W PSU 80+ PSU, 230V. So assuming worst case PSU is at 80% and burning 52W.
So raw board + fans of 210W. Each small fan is just over 1W, and assume the large but rubbish ones are 2.5W.

Thats 195W of power draw from 2 boards. I thought we were expecting low 80s for overclocked clocks? Something seems wrong here.
Our experiment data:

70-75W on 1.03-1.05V (no overclock)
83W on 1.10V (no overclock)
~100W on 1.20V (no overclock)
~120W on 1.20V (overclock)
