[SOLVED] PC overheats and restarts

[pajamas456]

Parts:
CPU: AMD Ryzen 3950x
GPU: EVGA GeForce RTX 2080 Super Black
Motherboard: ASUS TUF GAMING B550-PLUS WIFI
SSD: Samsung 970 EVO M.2
AIO Cooler: Cooler Master Master Liquid ML240L RGB
PSU: ThermalTake 850W Modular
RAM: G.Skill TridentZ 32gbs (2x16gbs)

Tried to play games, such as Call of Duty: Modern Warfare and Valorant and both games forced a restart due to CPU reaching around 95C. Would upgrading to a x570 motherboard help with this? Another idea was to add one more case fan, would that help as well?

Have you reapplied the CPU thermal paste? Also does your AIO make any weird noises?

Note: AIO can get air bubbles causing your cooling to not work. There are lots of videos on YouTube that will show you how to get air bubbles out.

Thermal paste was reapplied. The AIO is not making any weird noises.

That AIO is small for a Ryzen 9 3950X. Try forcing the fan speed to 100% and see if temperatures drop. You should be able to set the CPU fan speed in the motherboard BIOS. If that helps even a little that means the cooler is too small and/or case air flow is not good enough.
