The 16A unit might be pushing the limits for 3 rigs…
[/quote]They can ramp up and you can adjust the overload alarms. My 32A unit has a 32A input but split into 2 16A banks internally. The bank that runs 3 rigs (12x 7970) is pulling 16.9A but i have pushed the “warning” to 17A and overload to 17.5A but it will let you go to 18A. If you were running 12x 7950s you’d probably be OK. I know you shouldn’t but hey, i’m a rebel without a clue… no… hang on… that’s not right…

Well i just purchased myself some more ammo against the heat war!

these thingies transport over 60m^3 off air pr minute!
which means i have complete air replacement of the entire room every 30 seconds 8)Game on!

Hahaha that’s awesome :D

Update on solution.
It did not work as expected, all my rigs went down due to heat -
Problem fixed.
Just took a step back and lol’ed at myself…
Went to the store to buy two more of those fans. now i have 4 fans pushing 3600m^3 of air pr hour, for a total of 14400m^3 air/hour. in a room of under 25m^3 thats pretty good ::)
Those white plastic “home” fans gets thrown away, you havent experienced a real fan until you buy those with steel blades and larger engine (it says wind machine on box, and they where correct!)Have 1 fan hanging from the large windows blowing fresh cool air in (offset from my rigs for saftety from rainy days! those fans has some awesome pushing power)
1 fan mounted behind the rigs on the windows for pulling hot air to the outside.
2 fans directed at the front of the rigs for getting that hot air around the cards away.[img]http://s23.postimg.org/u8c1askvf/DSC01639.jpg[/img]

PMSL - Mad max eat your heart out! :D
-
Ye guys are crazy, ;D looks like its going to get hotter this weekend, cant wait to see the modifications done come Monday.
-
i second that you guys are crazy :P
if the AC dies here in Texas this time of year, no amount of fans will cool a rig ;D

The modification worked like a charm!
Earlier it would overheat the entire basement when i closed the door to the second floor(due to heat in third floor where we sleep…)
When i would wake up the basement would be 45 degrees and halv my rigs would have gone idle. Now i have even closed of the small room so i dont overheat the basement, still the temp donot go over 80!http://50.87.190.116/monitoring/
Edit:
Now if i only could find a way to press in a circuit breaker more in my fusebox i can expand the park further ::) have used up my dedicated 7kW -

[/quote]To hell with the breaker - you probably have 25% headroom on that. Have you felt the temp of the cables coming out of it though?

[/quote]Allready have heat on cables/breakers. So think i have pushef enough:)
But maybe i get an extra 16amp when i change room, also i have an arrangement in progress between friends regarding alternative storage:P -
Knowing your luck and fires i wouldn’t want to sleep in your house! ;D
That’s why mine live in the shed.

In all my years of operating a huge cluster I recommend lowering your clocks and mem clocks to lower temps… you dont want to be constantly pushing ur cards above 90c. Also remember thermal cycling is more damaging to cards so glitching isnt good
[/quote]my cards are between 75-80 degrees 24/7 after installing these fans
rom temp is around 30-35degrees
