Hi Guys

My setup:

I’ve got 6 rigs set up with 12GPUs per rig (RX470 8Gb Nitro+)
I did put ground vent in but I put way too many stones in and it’s blocked so I later cut out 4 exhaust fans in the back wall (3 behind the rigs and 1 slightly aligned left of the rigs).

I also took a window out in front of the rigs for cold air intake. I put an insect mesh in place to stop bugs coming in and sealed the shed so it is air tight.


My problem:
A PSU failed a few months back and i thought maybe it was a roof leak but I found no leaks. Replaced the PSU and all was well. Now 2-3 months later the same rig has failed, this time it’s corrosive damage to the motherboard.

Any ideas?

I also notice my rigs randomly hang and restart. They sometimes work perfectly for weeks on end without reboots and then days like today they are hanging and restarting the miners on random rigs all day long. I suspect the Ethernet Switch is failing the same way the motherboard and psu did..
