PC unexpectedly shutting down

[heleves]

Hi,

 

I had a topic earlier this day about my new R5 3600 and its temperatures. I noticed that they were a bit too high, on idle it was running around 50-60 celsius, and after a short testing in game it went up to around 80 degrees (the max was 87). 

 

Now that I've started playing for longer periods, it shuts down unexpectedly. I have a new Corsair RM650x, so I doubt that the PSU would cause it. I started monitoring the CPU temp after the first shutdown, but I haven't noticed anything extremely high (like 90). For whatever reason, it shut down a second time as well. That was when I decided to remove the side panel and put a ventillator next to the PC. It didn't shut down ever since (~40 mins in game), so I think it will be a temperature problem.

 

What could it be? Is there any way to monitor other devices as well? I have a 1070 FTW from EVGA, which never goes above 70-75 degrees, so that's out of the question as well. What could I do to fix/investigate this?

Hi,
A new cooler should be anything but good for your 3600. I'm not saying that's the issue, I'm saying that could help to eliminate that concerns from the issue.
