Do your VRM temperatures indicate excessive heat or are the sensor readings unreliable?
Do your VRM temperatures indicate excessive heat or are the sensor readings unreliable?
I recently assembled my first rig and have been trying it out.
I’m using a Ryzen 2200G with a B450M-Pro4 board, Cryorig M9a cooler, 8GB RAM (2x4), and four 120mm fans (two front intakes, one rear and one top exhaust).
Stability tests with HWInfo64 and Aida64 ran for about 10 to 15 minutes, and everything looks fine. Idle CPU temps are around 27-29°C, peaking at about 55-57°C.
The concern is the VRM temperatures displayed on the Aida64 test screen—when idle, they always read 99°C. Is that normal or a problem?
Apologies if this seems like a simple question; I’m still getting familiar with all this.
To verify the readings, it helps to physically check the VRM temperature by touching the heatsink. This can confirm whether the data matches what you expect. The airflow description seems reasonable on paper, but details about the case's make and model could change things. Since your cooler is tower-style, there may be limited airflow beneath the heatsink near the VRM area.
Also, keep in mind to apply the most recent BIOS update for your motherboard.

The chance your VRMs are really hot is minimal, and it would cause plastic parts on your motherboard to melt. If a sensor fails, it often displays either 99°C or 127°C continuously, indicating the sensor is likely damaged—no need to be concerned.
It seems the reading '99C' appears even without load, suggesting the sensor might be incorrectly labeled in the monitoring app. Try another sensor reading that correlates with processor activity, possibly accounting for the large passive heatsink affecting cooling and reporting a temperature more typical of the VRM. You might also consult the forum on Martin's website regarding HWInfo64, as he is helpful with feedback on issues like this and could potentially address the problem in the next update.
For a new build, it’s likely a fresh motherboard; if the sensor fails, consider replacing it with a working one.
