That looks like a very warm and noisy setup. Is the door closed when you leave it mining? Interested to know what temps you get on those ASICs and GPUs. I can imagine the data center closes the door while you are mining.
The datacenter has a hot and cold aisle in my picture I have a locker which has the door closed but air can pass through. The picture is the front of the cold aisle which runs around 70 degrees and the back is the hot aisle. Temps for ASICS run between 60 to 85 . Temps for gpu are around 60 to 70.
) The heat from the units does cause the AC to run a lot. Utilize cool outside air when ever you can by opening the windows. I've been toying with the idea of venting the hot air outside but that would require a window be open and then I would be venting the nice cold AC air. I should decide what to do soon though because its going to start getting hot again.
