Question Are these normal temperatures for AMD Ryzen 7 5800X?

[cioden]

Hi there I have newly built pc after not having a desktop for many years, I've never had an AMD cpu so I was curious if these are normal temperatures? From what I've read the 5800X runs hotter in general. The tdie temperature seems to stay around the 40's to 50s bouncing around depending on what I'm doing. When gaming I've only ever seen it go into the 70's. The cooler fan speed seem to generally be around 800 to 900 rpm. My cooler is a Noctua NH-D15S, with one 140mm fan. It has the option to have a second fan to be installed but would that help much?

Here's is a cinebench test I ran awhile back and turned on smart fan mode for the case fans.

Maybe a little toasty, I have the same cooler on my 5800X3D in a mini ITX case (Fractal Torrent Nano) and my core temp is not crossing 76C after one 10 pass run of Cinebench.

It could be down to the brand of thermal paste you used.

I also had a heating problem when I initially installed the D15S on a different CPU because I accidentally pointed the fan in the wrong direction.

Looks about right considering VID is 1.45v.

You can bring those load temps down a little-lot by using the core optimizer.

AMD has told us that temps up to 90C are normal for Zen3 CPU's so what you're seeing is perfectly acceptable temperature for such a heavy workload like Cinebench. I'm getting in the low 80's, 81-82C, for similar workload on a 240mm AIO for reference.

Assuming you use the stuff Noctua bundles with their coolers I doubt you could get any better by changing the thermal paste as it's already pretty good. Based on paste reviews, even if going from worst to best the most you'll get is a couple degrees C anyway so it's probably not worth the trouble and risk of damaging something IMO.

I definitely agree that working with curve optimizer can help. Even if you don't see a dramatic change in temps you will definitely see improved performance if you also add in some boost offset. That's because the boost algorithm uses the 90C Tjmax temperature as a limiter so it will tends to boost higher with the offset, and longer, until it reaches higher temps, above 80C generally. Curve Optimizer lowers the voltage so it will be able to run a higher clock at a given temperature with increased performance a result.

Fairly normal. I get 88C with a Peerless Assassin 120 on a 5800x3d with a CineBench23 all core run.

You are good to go as the cpu is not being throttled due to heat. It's rare in general pc usage and gaming to load all cores at the same time for an extended period.

Hey there,

IIRC the Noctua doesn't benefit much from the extra fan. Will try remember and link the article!

Your mobo hasn't got a very robust power phase/vrm set up. Don't go overclocking the CPU, as you might find some throttling going on.

As the others have said, higher temps with a 5800x is to be expected, for the most part.

Try core Optimizer with -20 all cores, that got me down about 5c with CB r23 score above 16000 and temps up to 82-83c at 1.32v with a 360 AIO.,some times less is more. Although AMD says that up to 90c is fine,it still limits boost over 85/86c. Best results at up to 80c.
Edit,
in CB r23 all core max is 4.76 and single core 5.05GHz.CPU stepping isB3 and with B0 you should get some 100MHz more with same settings.

Sorry for the late reply, I wanted to say thank you everyone for your help! I used the core optimizier and it recommended an offset of -30. After applying the offset it looks like the average temperatures dropped a few degrees and increased the cinebench score. Here are how things currently look.

Looks about right. Ryzen don't have a 'set' boost, they have an 'upto' boost. Low loads don't punish a Ryzen with heat-work, so they'll boost high, heavier loads are more taxing so boosts are respondent to the voltages and cooling. With enough cooling ability, you'll still get the boosts, high and long, because voltage will be the limiter instead. Drop the voltages and you can see max boosts, for max time, at minimum temps.
