I have both an RX 580 and RX 590, both Nitro+. They work fine on silent mode and regular mode; is your card getting enough power? Are you using both 6+2 and 6 pins connectors? Or are you only using the 6+2 connector?
I've used both of these cards on the Z390 Aorus Pro, Z390 Aorus Pro WIFI, Z390I Auros Pro WIFI and now the Z390 Aorus Designare. Both of these cards work great, with either BIOS switch setting. I did always install them on PCIE slot 1, except on the Z390I which of course only has 1 slot
Note that these cards only have the newer EFI video driver stack, not the older legacy driver, so some OS like Windows 7 will give you a black screen unless CSM is enabled, but this is not a failure with the card, just a driver issue. A modern OS like Windows 10 and I'd imagine Mojave/Catalina, doesn't need CSM enabled to work properly though.
In my cases, the fans stay completely off (0 stop) in either mode (silent/standard), as long as the temps are low. I think 50C is the actual temp where the fans kick in. With such a big heatsink, I'd imagine the card can stay cool for a few temps
EDIT: Another thought, are you using the default VBIOS for the card? Or did you modify/switch them out? I know allot of people do this for compatibility or other reasons. [FYI] Mine are running the stock VBIOS that they came with...
About VBIOS: I actually got it used so I have to ask and find out about that. Sadly I don't have windows installed on this machine and I don't know if there's a way to find that info in MacOS...
By the way one of the two BIOS settings on the GPU hangs on BIOS with CSM off. The red light (VGA) on my Designare z390 stays lit and the Boot doesn't ever proceed, can't even get in the BIOS itself.
I noticed that on 50 degrees the fans DO start but they never go higher than 25%, even on 75 degrees. The performance is great but that fan curve concerns me a bit.
