HOT RYZEN 9 5950X TOO HOT?

[Hankieroseman]

My Gamer, built for MS Flight Simulator 2020, is buttery smooth running the defaults. Installed 'Core Temp' 1.17.1 and it's reporting a steady 80º C when flying. The CPU is paired with Noctua NH-D15 Chromax with dual fans. It's been suggested to try re-paste the heatsink before going AIO liquid and possibly having to change the case too. Thoughts and experiences?

One more question, what is the max size you can run fan wise on the back exhaust fan behind the cooler? can it fit a 140MM fan? is the existing one a 120mm?

that is the only other thing other than changing your cooling system that I can think of, after looking at all this , if the Noctua is working right that you have some kind of
airflow bottleneck there.

A 140MM without a grille cover might made some difference.

Hmm I dont use Rysen Master - But have you set up PBO in bios and what is your PPT, TDC and EDC settings in bios? You can find some guides here https://www.techpowerup.com/forums/threads/amd-curve-optimizer-any-guides-experience.275640/

do you remember the game you were playing when read 80° ?
Because I never saw anything like that, playing quite a few different games.

War thunder and ROR2 don't use much CPU.

MW2019 hits 80-85 regularly at 100% load on 2 cores. Though that's not entirely accurate, it almost always hangs out in the 70-80 range but on Ryzen 5000 CCD1 temp gets spiky when maxed out on just 1-2 cores with these very short spikes.

Minecraft when using shaders has piss poor optimization and hits about 80 max.

Some old games like Project Reality are fully CPU bound and only use 1 core, also hit about 80 while maxing out clocks on that core, ~4.8GHz sustained.

I do run a flat 40-50% rpm curve on my iPPC-2000 though, improves about 1-3C with higher rpm.

im not sure how the x570 bios is set up with ASUS but on my ASUS x470 you can go here and limit the CPU temp, weird thing is even after doing that my 5900X clocks remain about the same and it had no impact on my cinebench scores except im not hitting close to 90*

Btw heres my temps after some ours of gameing

I never saw temperatures above or at 80° while gaming on my 5900X.
I had some spikes at 75/76° but usually temperatures are in the 68/72°...

Even on my son's 5800X , where temps are a little higher, the game while gaming is 72/75° and spikes are below 80...

Okay, good to know...? What are you implying? I pointed out those games because they seem to run particularly warm on my 5900X, with temp spikes especially in MW (and seem to be corroborated by other 5900X owners with similar performing coolers to mine), hoping that you'd happen to play some of those games too so we'd have a point of reference, but if you don't play those games, what's up with vehemently insisting that it's not possible?

Some of those anecdotal accounts are running D15s on 5900Xs and see very similar 80C temps and 85C spikes in MW as well. I mentioned it because OP originally mentioned high temps in FS2020 - FS2020 is an AVX game just like MW2019, but temps seem not to be a problem anymore for OP, so it's just an interesting observation.

I'm implying that your case doesn't have a good airflow or your cooler is not correctly mounted (could be poor thermal paste or a bad distribution). Or a combination of the above.
And if the case is the one you have in your system specs, I think it is the reason.
Not a big deal, but not an ideal condition for a 5900X.

Having had a 5950X before, I can definitely agree with what the box says: "liquid cooling recommended". I'd only amend it to: "at least a 240 mm AIO recommended". With a Corsair H100i Platinum, I managed to keep the temperature of mine in the lower 70s under full load with low noise levels. I would never recommend air cooling or any 120 mm AIO with the 5950X.

Edit: You can try re-mounting the heatsink with good quality thermal paste, and/or disabling PBO and other performance enhancements in the BIOS, but I don't think it'll help.
