Understood a bit better now. If it performs as it should with APM disabled during stress tests than nothing to worry about. I have heard UD3's can have issues with VRM's due to bios (causing throttling) but usually not an issue till closer to 4.6 to 4.7 if I remember right. Have you added any active cooling to the VRM HS? You might not need it yet but something more to watch for!
