Question AMD FX 6300 "reaches" 206 c°/402.8 °F

[frafurio]

Hello, 3 days i ago i changed my old motherboard to an msi 760gm-p23 fx.
I added my AMD FX 6300 and my RX 550, yeah yeah i know, old stuff, but that's all i can affoard.

The problem comes when i start up a game, for example gta 5. When the CPU temp sits up to 67°C, the game goes smoothly.
But as soon as the CPU temp goes to 68°C, it automatically goes to 206°C, throttling the performance and making the games run at 16 fps.
Worst thing about it is that it does not stop until i reboot. I can close the game, keep my pc on the desktop so it cools down, but if i reopen the game it will still measure 206.
This has never been an issue with my old motherboard.
Now, of course this is an error in measuring the temperature, otherwise my pc would catch fire. I have searched the internet and apparently this is a common problem with this MoBo, but i can't find any solution.
Is there any way to fix this?

Please refrain from telling me to buy a new MoBo, i am broke af, i don't have more money to spend on this stuff.
I just paid 47 euros for this one wich is what i make in 2 days of work (that's Italy for you)

Unfortunately, it's probably the combination of your CPU being too hot and a very cheap motherboard that wasn't really intended for AM3+ CPUs (760G motherboards were basically retrofit to work with them). Those AM3+ CPUs aren't like moderns ones and will start throttling at these temperatures, so they have to be cooled properly.

Another problem is that software did a notoriously poor job at reading temperatures of AM3+ CPUs. You basically had to use AMD Overdrive to get an accurate temperature (expressed in thermal margin).

but i never had problems with the cpu heat with my old motherboard. It would go up to maximum 71°C and sit there with no throttling. Is there any way to "hide" or "fake" the temperature so this does not happen? Or make it recieve the correct temperature? I can guarantee that this cpu does not throttle when it goes past 67°C, it does now because it thinks it's at 206°C

No.

First thing is to get an accurate temperature. Unless you're using AMD Overdrive, you're getting a wild guess.

And it's hard to contrast your current motherboard with your old one when you don't identify it. If the old one was working fine, why replace it? Advice is better when we know the entire story.

And again, this was one of the lowest quality motherboards to run AM3+ and it's more than a decade old. Many things could be going wrong.

the old motherboard is a Asus M5a78l-m Lx3, not working anymore

just tried AMD Overdrive, still gave me the wrong temp. As soon as i hit 68°C, the AMD Overdrive Thermal Margin went from 2 to -185.0

update: i pointed a fan on the mosfets at the cpu's left and that does the trick, no more 206 degrees. Apparently the mosfets tend to overheat and that causes the misreading
