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
