If your idle temps are at 45, that around 10 more than mine to begin with…although with the 307A limit, I only reach around 80+ish degrees if I remember correctly…so that’s still a big difference. But maybe you just have an even hotter room than I do, so it struggles to cool things down once they do start to heat up?
I guess the only other thing you can do is check that your fans and pumps are at full speed after a certain temp is reached?
I’m also wondering if there’s another setting in your bios that’s been changed somewhere that is preventing the limits from being obeyed? If you run something like hwinfo64 during the cinebench test, you can see what the power the CPU is using to confirm it’s not going above the 253W limit you’ve set.
Might be worth resetting default bios settings, then only setting power and current limits, keep everything else default (except you can also disable any automatic overclock or multicore enhancement or whatever).
But yeah, I’d guess that with idle temps of 45, maybe you just have a slightly warmer room and that’s why?
Either way, it’s still technically safe…that’s why the thermal throttling exists…to keep the CPU from dying…this gen of CPU DO RUN HOT. It won’t be hitting 100C continuously in actual games or in the sim,…cinebench is good for getting a benchmark comparison to other systems I guess, and can be helpful in determining quickly if something is very unstable, but I wouldn’t get too hung up on it…it’s not a real-world use case.
hwinfo64 sensors are really helpful to see what your system is doing, so if you’re still hitting 100C continuously in the sim and being throttled down harsh, then maybe there’s still more to be done?
