I'm going to pm you with a few questions I have!

This isn't true for my experience.  You can feel the exhaust coming out of the backs of my cards (opposite to the I/O).  I had my cards hanged vertically before, and it was terrible.  Changing the orientation saved me 30% on my temperatures.  When the cards were hanging the exhaust shot right back up into the card since heat rises.  I don't know if it's just my 6161kr 1060's, but that's how it is for me.  I agree with heating up the card to the next.  I suppose I'll just have to find racks that are the right size.

I'm not familiar with "dew points".  However, the intake vent is from a larger 100,000 sq ft warehouse that's dry.  That's where new air comes in.  I don't think I should be affected by any moisture then.  Am I wrong?

Hello everybody!  I have 4 gh/s of gpu miners in a space I rented out nearby.  It looks like my 10000 cfm exhaust and intake vent are cooling it enough and my power situation is fine.  However, power density is now my issue.

I'm looking for a rig-building solution that does the following

- Allows me to build higher without heating problems.  Rigs are currently below 75 in 100-degree weather.  Most are in the 60's.
- Looking to exhaust the cards all in the same direction.

Currently, my cards are all exhausting away from eachother and into the next rack.  It works like this.

Intake vent > Card exhausting left > card exhausting right > space between rack > card exhausting left > card exhausting right > space between rack > exhaust fan.

The room is in the shape of a small storage container.  It's only 250 square feet so there's not much room to work with. My intent is to make it a wind tunnel.

Therefore,  my design needs to be like the following.

Intake vent > card exhausting right > space between rack > card exhausting right > space between rack > card exhausting right > exhaust fan.

This way the airflow will go in one direction in addition to the pressure drawn from the exhaust fan.

The first pic on this article is very much how my rigs look.  I put them each back to back so that they don't exhaust into eachother.  I put my rigs on metal racks that go 2 rigs high. 

Below is a picture of somebody going 3 rigs high.

Anybody with bigger farms want to share their info?

evga supernova 1600w p2.  Is there any custom firmware for the a3?

Anything optimistic you can do to help ?  Give me some hope.

Only chain #3 is detected and I'm hashing 276 gh/s. 

When I setup the miner I had all 3 detected and hashed for about 15 minutes.  Afterwards, the asic was showing only 1 detected.  I've tried restarting, reseting, changing power supply cables, and changing power supplies.  I even tested all power supplies and they all work.

Is there anything I can do before sending it back?
