My 2700x system is idling between 50-60C and the fan is going at 2600 RPM as soon as I turn on the machine. It also immediately climbs to 70-80C when under any kind of significant load, and then crashes as soon as it gets over 85C (black screen, no BSOD, etc.) It crashes in any kind of moderately intense game such as Planet Coaster, and it also dies immediately when I try to run Cinebench 15 on it. It won't thermal throttle - it just blacks out and requires a hard reset.
Specs:
Ryzen 7 2700x (running at stock speed) and a stock cooler
MB: MSI B450m Bazooka V2
GPU: GTX 1660 6GB
RAM: 16 GB at 2666 (unknown brand)
WD Black NVMe 500GB (main boot drive)
WD Green 240 GB SSD
Seagate Barracuda 2TB HDD
Thermaltake Smart 600W Powersupply
It's a pre-build from CyberPower PC, but I'm not hearing back from them and thought this community might be able to help give me some ideas on where to start. I'd think it was the PSU, but the processor spikes so quickly to 80C under moderate load that it makes me think the heat sink isn't set right or that the processor itself may be faulty. Any ideas are very appreciated. Thank you!
