No VRM temperature is provided in UEFI and ASRock's monitor utility(A-Tuning). I could only find CPU temperature and M/B temperature, and M/B is only 20°C.
Dir sir/madam, I have an ASRock B450M Pro4 motherboard and I saw in AIDA64 (latest stable/beta versions) that my board has a really high VRM temperature near 100°C. Moreover, this temperature would not increase/decrease much when my CPU is overloading/idle. I touched the power chokes and it doesn't feel like boiling water. I think this might be a bug.
