Is the motherboard heating up?

Question

Cooling systems

ran into a problem a month ago, when starting cs-go in competitive mode. the monitor goes out and the computer freezes, then the cooler starts to buzz loudly. the computer turns off only by turning off the power. when you turn on the monitor, it goes out, every 5-10 times. and when you boot, everything becomes normal. I replaced the thermal paste everywhere.
Everything was fine for 2 days, then again everything was the same.

Answer 1

Is the body blown out? Mosfets are blown by a cooler? They are installed under the boxed cooler, if the cooler is not boxed, they would throw radiators on the mosfets.
