Ryzen 7 5700G crashes when hitting 80ºC/100%

This is a brand new (few weeks old) APU that's working wit the following hardware:

Motherboard: B550M-A Pro from MSI,

PSU: CoolerMaster MWE 450 Bronze v2,

Processor: Ryzen 7 5700G,

RAM: Crucial Basics 16GB (x2) DDR4-3200 UDI,

Cooler: Stock

 

I'm running it on Linux, and since the beginning the only BIOS/UEFI changes were disabling the Secure Boot, without which Linux won't boot. Everything had been working fine, except I noticed random shutdowns sometimes. I thought it was a loose power cable (old), I replaced it and went with it. Most of the time, nothing goes wrong, the system remains running for a day or longer on usual work that's not CPU-intensive. I had also been told that I should've updated the BIOS, I noticed there's a beta update and did it, but that didn't help with anything.


The moment I noticed more frequent crashes was when I started doing my development work, where I was compiling a large program and the processors would gradually hit 99-100%, it'll stay there for sometime and the temperature goes upto 80-81ºC and here if I leave it it'll run for some minutes then crash, or even if I do interrupt and kill the process with Ctrl + C, the system also crashes.

 

This certainly isn't expected behavior, I don't plan to run at 100% longer, but I need stuff to compile. I've searched, and I've found undervolting might help, some say to get a dedicated cooler and others say its a faulty CPU.

 

I haven't tried undervolting or messing around with PBO or anything, because I don't understand it and wouldn't want to void my warranty, and I've ordered a Hyper 212 (its cheaper here) already to fix the heat issue.

 

I'd really like some advice on fixing and optimizing this build for development on large applications.

The problem has been rectified, it was a pure overheating issue. I tried the compilation with the case removed, and it stays above 85 and 90C smoothly. I'll put a fine cooler and keep it in a better place.

I was going to suggest a better CPU cooler for your build.  Let us know what your CPU temperature reaches after you install the Cooler Master Hyper 212.
