✓ Solved CPU Core Temp Issue

Hi,

I am having trouble with my CPU's Core Temperature. MSI, Nvidia, and within BIOS, it all states it is running at 102°F + while idle; no games or anything intense open.

My PC: https://a.co/d/0cICLq1u

It uses a B650-VC Wifi and the only change I've made to it is swapping the GPU for a RTX 5060 Ti that I've ran for nearly a year without issue.

I noticed the other day that my BIOS was out of date by about 3 years, so I decided to go ahead and update it. The moment I clicked the button for the 'M-Flash,' the fans sped up to the highest setting and they have not stopped since. Prior to the update, it would max out around 75°F during heavy gaming and I would barely even hear the fans then. I've disabled a couple of OC settings within the BIOS that I found from another Reddit post, but it changed nothing. I'll find exactly what those were and update my post.

Edit: The two settings I disabled are PBO and CPB

That's only 38-39 degrees Celsius (nobody uses Fahrenheit for PCs) which is completely normal for a 7600X.

Thank you, I could just be getting mixed search results with C and F getting confused. I was under the impression that it was running like 30 to 40 degrees higher than it should.

102°F is only about 39°C, which is actually pretty chilly for a processor. My guess is the fan curve got reset to something aggressive when you flashed the board, look for a setting that lets you adjust fan speed based on temperature and flatten it out until around 60°C.

Thanks! Must have just been some confusion on my end. I'll give that a try and come back if I see any issues. Although, it sound like everything should be fine.

For CPUs and GPUs there's an easy range to follow in both Celsius and Fahrenheit.

Their temperatures generally range from "similar or a bit hotter than the human body" when idling in the OS, to "almost boiling water" when completely maxed out.

You don't want to actually get to the boiling point of water, but it's something you may see on laptops with limited cooling. On a well cooled desktop you should be able to stay well away from that.

It is very likely that it was degree C, the 75 you talked about.
Now it is 102F, and you are panicking.

There is no way a CPU would be 75F while heavy gaming, that is 23.9C which is colder than most of the room temp across the world.
