What are your VRM temps AB350 pro4

According to the motherboard specification, this board does not have a temperature sensor for the VRM, only for CPU/chassis, so values given by various software are either from some other sensor or just pure nonsense.

If you want to know the VRM temperatures, you need to measure them yourselves. If that's not an option, you can use Hardware Unboxed's B450 VRM temperature test as a reference, since the ASRock B450 Gaming K4 seems to have identical VRM and VRM cooling as the AB350 Pro4. Here's the link to said test:

Based on the video VRM temperatures should not be of great concern on this board. Then again, I think Buildzoid said in one of his videos that none of the B350 boards are that great for eight core Ryzens, at least if you plan to overclock the CPU. The VRM's just aren't that strong in any of them. This board's 3 + 3 phase desing has some benefits, but it's still just 3+3 - not the advertised 6+3.
