This is the scheme of my setup. Is a box 44cm wide x 32cm high and gpus are setup on two levels one on top of other. (1060 3Gb gpu)
There is a raspberry pi wich allows me to reset/poweroff-on and control the inside temps using 5 sensors DS18B20.
12 fans push fresh air inside the box. They feed on an external psu. Temps with power limite 92W are 57-68ºC.
By the way I had a big cpu load (5-14) when I had power limit to 72W. Once set to 92W got down to 1.5-2.2 (yes I know no good yet, but much better).
I use a celeron g3900, looking forward to upgrade to I3.
I post this hoping the schematic helps others like me who have their rig in remote locations.
Here the code bits for temps, poweron/off and reset.

Hey man, that's a very nice DIY project you have there! And great schematics btw, thanks for sharing. I'm wondering, how much did it cost overall (Pi + fans + sensors and parts)? Did you try integrating it with nvOC's auto temp control, which uses the GPUs internal temp sensors, instead of relying on the DS18B20?
I'm facing some heating issues here, as the days are becoming hotter, so I'm thinking about what to do. I don't want to leave an A/C on all day, because of energy costs, so probably will need something to suck the hot air from the GPUs to the outside during the day, and reverse direction at night, when it's colder outside. Your project really gives some ideas...
