Is it normal for a PC to shutdown at 185°F?

2021-04-19 6:57 am

I was playing a game on Steam earlier today, no problems, all of a sudden, my PC just shuts down. I attributed the shut down to overheating of the CPU, because in years past, that's always been my number one problem.

So then I was running a program called Core Temp. So after a bit I got back into the same game, saw the temps getting into 170°F so I quit the game, closed the Steam program, and my temps weren't dropping. Then I see the temp jump to 186°F and black. Everything shut off again.

Google search brings up results that 100°C is when a PC would shut down, but mine shuts down at 85°C. I am running the AMD FX-8300 chip so not sure how much of a difference it makes vs. running Ryzen or a newer Intel chip.

So is my PC shutting down at 85°C normal for that chip then?

更新1:

The PC is 6 years old. It's running a GTX 970 and the same PSU I originally installed. No, it's definitely temperatures, because once I took off the side of the case, my temps were holding at around 155°F to 160°F. Other problem is my heatsink. It needs to be larger with a larger fan on the heatsink.

There are other parts that can overheat which will cause the system to shut down. If the VRM's (Power Delivery system) to the CPU or GPU overheat then the system will shut down. Also, overheating RAM modules will cause the system to crash and shut down.

The 970 is an old card and so it the FX-8300 series CPU you have. Maybe the paste is dried up and cracking. I would suggest repasting the CPU and GPU with a good paste like MX-5 and giving everything else a cleaning.

AMD uses a different algorithm for monitoring the CPU temps of their FX processors. These conventional thermal monitoring programs are made for Intel processors anyway. According to what I've heard, you don't want an FX CPU to run past 62c with these thermal monitoring programs.

How do you know that your power supply is not the culprit? Perhaps that gaming board that you put in is making your power supply just a little bit too hot and the thermometer inside of your power supply is what's kicking out.
