2018 Mac Mini eGPU: Fans 100% While Mac Sleeps

[Engender]

I wish I could see my signature while I write this, but I have a Sapphire Pulse RX 580 in a TREBLEET Tbolt3 enclosure. When my Mac is sleeping, I will hear the RX 580's fans spin up to 100% at least every hour.

Does anyone else have this problem? Does anyone know the solution? It's not preventing me from using my Mac, but it sure is annoying.

I have turned off "Enable Power Nap," because I thought that would mean that my Mac would not wake during sleep. I don't have any . . . here you go:

Thanks for any help you can provide!

Use the free trial of https://ohanaware.com/sleepaid/ - it's a very comprehensive way to diagnose sleep/wake issues.

I did the following to stop periodic "stealthy" wake-ups causing eGPU fans to spin up. Not sure if it's still sufficient on the newest OS though.

# Stop the Mac waking up approx every 2 hours from Sleep.
sudo defaults write /Library/Preferences/com.apple.mDNSResponder.plist NoMulticastAdvertisements -bool true

# Stop nearby devices associated with the same iCloud account from waking the Mac, e.g. when opening AirPods case.
sudo pmset -a proximitywake 0
