Well.... do you have any kind of monitor software on your PC-- such as SpeedFan ??

It would be a good idea... to me. It's better than being unsure. Gaming pushes your system harder than just about any other activity -- everything is stressed-- especially your
CPU/video card. Stress generates more heat. Heat is your
CPU's enemy... and it can cause permanent damage.
Another thing to try first-- have you
cleaned your PC lately?? It is one of the most overlooked problems. the cooling fans are constantly circulating air through your case. I clean mine about once a month-- sooner if I see temps creeping up. Cooling fans and ducts (if present) MUST be kept clean/free of dust. It clogs filters/slows shaft speeds.
I would still recommend SpeedFan or Motherboard Monitor-- they are both free and can be set to "alarm" if your fans are running too slow or stop/check
CPU temps.
If you game-- you need them.
