I hope it's just a problem with the monitoring software. The CPU temps are off the charts, the core temps are, well, almost twice as they need to be, and none of the fans and/or pumps are spinning.
Well the dragon center is still showing that but i just dowlanded ryzen master and it shows properly now lol. That 255C is not someone would want after they just build their new pc
hwinfo and ryzen master are also about only monitors that get the speeds right on some Ryzen cpu.
Would think motherboard makers would have it looking at the right sensor.
I know there are often sensors on motherboards that always show wrong temps. My asus used to have one that was -120 c all the time which was tricky.
