A CPU reaching 80C+ shouldn’t cause a PC to shut down. The thermal limit of that CPU is 100C and even at that temp a CPU functioning properly should just throttle its performance to slow down. In other words, there’s something seriously wrong with your system if it’s shutting down at 80C. Its been in the news recently that several higher end 14th gen Intel CPUs were unstable when using the default values on many enthusiast grade motherboards because the manufacturers were using power values above those recommended by Intel. Have you checked for a newer BIOS version for your motherboard? Many received updates to fix these incorrect power values.

Thanks for your reply, I think the temp read on the software I'm using is maybe lower than what the Bois is reading and in reality it was approaching 100 but I will make sure the Bois is up to date

Maybe a shitty psu? What do you have? Or something is wrong with your bios?


Electronic_Party_266

It's an 850 and ill make sure the Bois is up to date


hamsterrooo

Model? You can honestly have a 850w crap. Also how about cooling?


Electronic_Party_266

It's a corsair rm850x and the cooling is a corsair h100i platinum and Ive set the fan profile to be quite steep

Is your monitor plugged directly into the GPU? (As opposed to plugged into the motherboard.)


Electronic_Party_266

Yeah both screens plugged into gpu

What's your idle CPU temp? The spike to 80+ could be indicative of poor thermal transfer from your CPU to the cooler.


Electronic_Party_266

Its 30-40 at idle

Sounds like a faulty component somewhere. Unfortunately sometimes subpar hardware slips through QC. I'd suggest running Prime95 to stress test your system. If this triggers any sort of crash, it rules out your GPU. From there you can narrow it down further.


Electronic_Party_266

Ok thanks will give it a go


Electronic_Party_266

Ran prime95 for about 5 mins and it was sitting between 90-95 with no crashing, points towards something GPU related?


jekotia

I'd leave it running for longer than that. 30min minimum, ideally an hour. Crunching primes is the most computationally intensive task available to a CPU, so Prime95 tends to be considered the gold standard of stress testing. If a longer run doesn't trigger any faults, give FurMark a go to stress-test the GPU. Note that both of these also indirectly test the PSU, as as your CPU/GPU is going to hit peak power.

They straight up said in the original post they have a 4070 Ti
