what cards are you running? and hows the temp?
This one is a mix of GIGABYTE Aorus RX580 8GB, and a few MSI GAMING X RX580 8GB.
Temperatures are good, I target 68C (no A/C), seems to do just fine. The spacing between GPU's is much wider than other rigs that have been running for 18months+.
I've been weeding out the 4GB cards over time, rebuilding rigs and cleaning up/servicing GPU fans along the way
What are your fans running at?
Do you got pictures of your setup?
