From one youtube, you can see other model has higher temp, if your PC runs fine, not shut down, then you should be OK. https://www.reddit.com/r/Amd/comments/93eal1 View: https://www.reddit.com/r/Amd/comments/93eal1/b450_vrm_temp_test_asus_gigabyte_disappoint/


If you want to low the temp, make sure your case has good airflow, like in the linker setup. https://cdn.macovi.de/media/content/datapages/1563/images/CARBIDE_88R_AIRFLOW.png

But one thing, I saw the +5V voltage is very bad, it shows +3.1V. And update the chipset driver first, then you should go into the BIOS, double check the +3V to see the real number. If it has only +3.1V, and you should buy other PSU.

The pro4 series are fkin garbage. Not just vrm - wise. Use the warranty to get another brand, preferably msi

I don't know that you're exactly reading the VRM temp. Utilities are notoriously bad at reading random stuff that leaves you confused but I'd trust HWInfo64 more than Aida64 since it's frequently updated. Be sure you have the latest. You can also go on the HWinfo64 website and Martin is really good about answering.

This is a why an IR thermometer is a great tool to have...check temps on and around the VRM while operating to know what's really going on when you can't trust your sensors or utilities.

Also double check that you didn't mess up the mating of the VRM heatsink. People use it as a handle as they're putting the board in and don't realize they left it skewed and not making good contact on the FET's.
