Hello all, So I just upgraded my Mac Pro (4,1 flashed to 5,1) with a RX 580 Pulse 4GB and I'm running into a strange issue. For some reason the fan that cools the PCI section is louder than usual. When I launch a game (in Windows) after a small amount of time the machine cuts out and it sounds like all the fans are running at maximum speed. (Namely the PSU section) Tried resetting the SMC with no positive results. Anyone know what could be up or what I could try? Greatly appreciate your help.
