What is VRM-TEMP-CRIT?
Power cascade overheating (VRM) (VRM-TEMP-CRIT) is a high-severity fault affecting the processor (CPU). VRM sensors on the motherboard report critical temperatures limiting the CPU. This usually traces back to dried thermal paste, overclocking too aggressively, silicon degradation and weak power supply. See the troubleshooting steps below for the fix.
Common Causes
- Dried thermal paste
- Overclocking too aggressively
- Silicon degradation
- Weak power supply
Step-by-Step Fix Guide
-
1
Improve cooling and repast
Improve cooling and repast tends to be the quickest win here, addressing the most typical cause of VRM-TEMP-CRIT.
-
2
Increase LLC (Load-Line Calibration) in BIOS
For cases that don't clear up right away, the remaining steps target less typical cpu instability problems.

3
Undervolting
Still seeing VRM-TEMP-CRIT after that? "Undervolting" is the next thing to check.

Frequently Asked Questions
The leading cause of VRM-TEMP-CRIT is dried thermal paste, though overclocking too aggressively, silicon degradation and weak power supply also show up in our reports.
Most VRM-TEMP-CRIT reports resolve after "Improve cooling and repast". The rest of the guide above is there for the cases that don't.
VRM-TEMP-CRIT is a high-severity error. It won't damage your PC instantly, but repeated occurrences usually point to a deeper problem worth addressing soon.
Usually. VRM-TEMP-CRIT is fixable with the steps above; a full Windows reinstall is rarely necessary unless everything else has failed.
Not necessarily. VRM-TEMP-CRIT can be triggered by software and driver issues, overclocking instability, or BIOS misconfigurations — not just hardware failure. Run through the diagnostic steps above before concluding the processor itself is defective.
