Hi all. I have experiencing problems with my Ryzen 5 3600. These are my specs:

CPU: AMD Ryzen 5 3600
Cooler: Stock AMD cooler. Now, changed to Cooler Master Hyper 212 cooler.
MoBo: MSI X470 Gaming Plus Max. Initially with the stock BIOS (2019-06-11).
RAM: Corsair Vengeance LPX 16GB (2x8GB) DDR4 3200MHz C16.
Graphics card: Sapphire Radeon X480 8GB.
PSU: Nox urano VX 750W
2SSD and 2HDD
Windows 10.

The problem is that since 2-3 weeks (although really haven’t tried games since mounted the PC), the PC randomly rebooted after playing different actual games except those with low CPU requirements (p.e. old Strike Fighters 2) and checking the temp with HWInfo, temperature was always close to 95Cº when i could check. Same in CPU benchmarks. Always with the stock cooler. Disabling PBO on BIOS didn’t seem to work.

Then I changed the stock cooler for the cooler master hyper212 and top temp in this setting has been 75Cº. Have run memtest and prime95 with no reboots, max temp…

Ryzen 5 3600 rebooting.
