Hi, I wanna ask if you have coil whine with your vega under macos
and random usage of graphic card.

When mac is under some load even video in browser you can hear coil whine from build.

For example, I dont have anything open , dont using mouse , just desktop in idle and you can see on vega led indicators that every few sec usage jump to 100% and than down..

You can see it on this video from vega build guide too
From 0:00 - 0:15

When I boot under windows everything is normal, no coil whine under 100% load of cpu and gpu, no random usage of card while idle .

Pleas do you know some fix for this problem ?
Thank you.

I have heard/read that the drivers in Mojave 10.14.5 are supposed to deal with this Vega fan issue. Is there a compelling reason you have remained on High Sierra?
