So my machines have been happily hashing for a few hours now, and my hash rate has been very good. Looking like about 5% above the specs averaged across the machines. However the temperature has me concerned. The fans maxed out at 100% nearly immediately upon beginning hashing and I have temperatures in the low 80s (F) according to the controller. Ambient temperatures in the shop are around 70F So it seems it should be able to keep the temps down. The shop is an open design, it is 1200 ft.², has 10 ceilings, and has lots of metal and concrete in it to act as a heat sink.
Can you folks take a look at this image and let me know what you think? Should I be concerned about the temperatures?
