And to think that I worry when my R5770s hit 60C. (it's 90F here almost daily - hot as balls) But then again, you're mining an order of magnitude faster than me

darkpandora, that is a cool idea. Let us know how it works. Like the bottom I'm guessing are intake?
the tow bottom fans are intake with dust filters, the four top fans are outtake. and the exhaust are intake, cool air from outside. works very well.
my temps are at 67 at night and 70 at midday, its summer here in Norway, in winter it will get very very cold
. and the overclock profile is on profile 1 on my 6990 (880Mhz).

awesome! are those exhaust or intake fans on top?

100F here in central Texas in the afternoon.
1.5Ghash/sec was getting a little warm, so I had to improvise a cooling solution
Wtf is that?! :O1.5Ghash/sec was getting a little warm, so I had to improvise a cooling solution
Please explain more
added another pic.
3 boxes, on a wire rack, sitting above a portable air conditioner (vents via hose in window)
plastic is to duct the hot/cold air directly into the AC unit.
How much did the temperature drop?
The problem was running the central air constantly to keep the room cool enough was costing me about $3/hr, this costs me about .10/hr

Now that's what I'm talkin' about!

Interesting. I almost wonder if it would be worth it to drywall around it to get better efficiency. Nothing fancy just stand up 4 walls and a roof. Put in a hinged 'access panel' (don't know if it would be worth putting in a door). I'm talking mcguyver style - no fancy studs or anything. Just drywall, corner connectors and screws holding it all together.. You could probably do it for less than $50. I bet it would pay for itself in two weeks, especially if the value of BTC drops.
Edit: I bet it would cut the noise too, but you may not care if it's in the garage.

on that idea, I would go with thin plywood, or paneling rather then drywall, easier to screw together

Awesome! I'm frying in the Texas heat myself - had to move my 'garage rig' to a room the the house. What's the air conditioner costing you to run?
it's about 1000 watts, runs constantly from noon-8pm, cycles during the night, 59Kw/h in the last 64 hours (Kill-a-watt meter),
so at .095/KWh * 59KW/h = $5.60 not too bad, I'm generating about 2.5BTC per day, so it's an acceptable cost of mining.
running the central air constantly to keep the room cool would cost at least 3x more.

I had rope holding 4 GPUS to the shelving top... But I came up for a more permanent solution and cut them all down. No pics unfortunately.

No, regular ATX. Maybe it's the perspective and the 120mm fans that makes the rest look smaller.

is that a pico-atx or something?
Wow.
Wow.

30°C outside, no idea how hot it's inside. New 5850 to go with the 5870. Didn't take long to figure out that it works better on top of that 10 year old case rather than inside.
I need a better CPU cooler. Or at least a syringe of thermal compound so I can get that chunky Intel thing remounted properly once I have taken it off to see how many dust bunnies I can find between the fins...

This is my 3rd mining rig. I call it, the Ticking Time Bomb!
It's... beautiful!
Quick question: why aren't the cards crossfired in that pic?
