Hello,

I have a somewhat similar setup in my 2 car garage as well.  I have 46 x 400/500 GPUS all mining.  I also have a set of those exact fans behind my rigs.  I keep both garage doors opened about 4 - 5" and have a couple box fans trying to pull some cooler air in, and not enough clearance for someone to crawl in.  I have considered buying a couple carpet drying fans to see if they help pull cooler air in, but I haven't done that yet.  I don't have the same issues that you do with the heat being 100 deg F (I'm closer to mid 80 - mid 90)

A couple of additional thoughts:
   - I would rotate the PSUs 90 deg so they are more flat.  This may help with the air flow
   - I would push the rigs back so that the GPUs are closer to the fans.  On my setup, I created alternating shelves and have the PSU/MB on one shelf and the GPUs on another shelf.  I used 2 sets of the inexpensive $40 Home Depot shelving, but cut the vertical tubes in half.  It created a pretty nice, dense setup and because the posts are 1/2 length, it's really rigid too.  On your setup, rotating everything 90 degrees and having the fans behind the GPUs and nor passing through the PSU/MBs may field similar results?
   - I would also look at how the fans line up with each rig.  The middle of the fan behind the plastic disk moves less air then the outsides.  From top to bottom, I am thinking rigs 2 & 4 may be having additional issue for this reason?

Hope this helps,

Good idea in the PSU's I could get more air past them to the cards behind them by doing this.

Also a good call on the shelves, it may not be a bad idea to look at putting the OTHER stuff on a shelf below allowing airflow straight to the cards

Oddly enough rigs 2 and 4 run the coolest of the whole bunch. I could move the rigs back or a also considered using the fans in a pull configuration as opposed to a push

Well I bought a 12" inline exhaust fan today, plan to create duct on the exhaust side of the GPU's to suck that heat right outside. Will see how much of a difference that makes. The fan is able to move around 1000CFM
