Hello, I got this Asus PC a ~year ago (GA35 G35DX-WB9931 - 90PD02W1-M00H10) with a Ryzen 5900x
I just saw that it runs 65-70 degrees Celsius on Idle (Liquid cooling system) while just watching twitch on 2nd monitor and browsing the internet on the other.. Is it normal?
If I could, I would attach a file from HWMonitor with it's readings.. Thanks in advance!
 
Yes I’d consider it normal. I have a Ryzen 3900X with Noctua air cooler and it hits 60-70 regularly on moderate loads (aforementioned auto turbo boosting). But booting up on windows safe mode and not touching anything, temps will be in 30-40s.

Used to run same CPU on stock Wraith Prism cooler and render video, it would happily sit on 90C whilst sounding like a jet taking off. Perfectly safe for the CPU… just loud.

I’d just leave your AIO alone. Attempting a repaste might void your warranty.
90C is safe for CPU? wow
By the way, by "same CPU" you meant your 3900x or mine 5900x? I got confused there.
Also for the QFan settings that I asked whether I should touch.. should I? Either I'm too tired right now and can't see where in your text you wrote about it. Sorry
 
I meant my 3900X.

A lot of laptops sit on 90-95C under load. Numbers look scary but the CPUs are designed for it.

Playing with QFan is up to you. Fan profiles are always a compromise between low temps vs low noise, so it’s up to you to decide what’s acceptable. Eg you could keep your CPU cool by running fan/pump at 100% all the time, if you don’t mind the noise and wearing the AIO out prematurely.

At what % should I run my fan/pump at?
Also if I run it at 100% all the time, how long would it last?
 
I should also add that one reason why enthusiasts obsess over CPU cooling is because modern CPUs turbo boost their frequencies according to a temperature matrix. I recall Intel Precision Boost having 3 frequency/temp tiers. It matters less with sustained workloads utilising all cores though. But we’re now getting into nitty gritty that you shouldn’t be too worried about.

I’d just run QFan at standard setting, and select “silent” or “performance” profiles (or equivalent) based on noise preference.
 
The temperatures shown on HWInfo in your pics look normal to me.
Not really. 70°C while doing nothing more than watching a video or sitting at idle is definitely not "normal". You are looking at only the "current" temp sensor reading, not the "maximum temp" sensor reading. You need to look at ALL the sensors, which is why it would be a good idea to post FULL screenshots of ALL sensors, which might take three or more screenshots per series, for both full "idle" and while running a full load. I would not recommend cinebench for this as it is not a steady state all core load. I would recommend something like Prime95 using the Small FFT option with all of the AVX options disabled, or the OCCT CPU stress test with the AVX options disabled. In any case, take full screenshots of both idle and full load sensor values. Not just one section of sensors, ALL of them in the HWinfo window. We can find discrepancies this way. And make sure all of the current, min, max are visible.

And as to posting the images, put them here, not where we have to go back and forth looking for them. As outlined here:

Intel does not have "Precision boost".

That is AMD and that is it's normal turbo behavior. It also has PBO, or Precision boost overdrive, which is the factory overclock and is generally enabled by default on the majority of B and X series boards. Even with a stock cooler, although it will be annoying, many of the Ryzen CPUs work just fine with PBO enabled and any of them should work fine if an adequate enough CPU cooler is installed, with PBO enabled.

My bad, getting them mixed up. Probably because Intel has renamed PL2/PL1 several times in the last few generations. But point applies to OP regardless.

OP’s HWInfo screenshot showed:
Min CPU temp - 44.1C (lowest 35C for CCD1 die)
Max CPU temp - 77C (highest 78.3C for CCD2 die)
Max CPU package power - 145W
Thermal throttling (for all 3 domains) - No

Nothing looked particularly concerning to me, but I’m happy to stand corrected.
I’m currently ignoring OP’s anecdotal reported “idle” temps, as they might have misread them (or erred in their recollections).

Here you go, 50 minutes. Like you said - Small FFT with all AVX options disabled.

This all looks fine to me, core temps at min/idle <40C and max temp 77.5C with no indicated throttling/Tjmax. Nothing suggests to me a major hardware problem.

If there’s anything to investigate, it would be OP’s software setup and the number of active processes/apps that get loaded up on startup and general use. Including malware.

But besides that I think it’s time to stop, and not generate any further untoward anxiety. IMHO. I’m checking out 😎

Well, I don't see any problems there, at all. So, that is with the side panel off though. Let's do it again, with the side panel back on, and see if the results are much changed. The idle temps are still higher than expected, but that might well be a result of the pump and radiator fan settings. They may have been set unexpectedly low to account for sound. IDK because I don't know what is connected where or how it's set on this machine, but it still feels like something is not optimal although the peak temps are what we are most concerned with. What it idles at or usually rides on doesn't really matter much so long as the max temps are within spec and for this, 90° is max SAFE spec. You'd really prefer to see about 5°C less max temps than that but all things considered where you are seeing right now is pretty ok. Check again with panel on.

I will do it when I get home. Thanks.
Also, that previous test was made with the glass panel on the pc. Later, I will do it with it off, and I will upload the results again! Thanks once again.
 
So, if that was with the side panel on, then you should be fine. Looking at the images of the inside of your case, seems like you might be able to figure out a way to get at least one, if not two, 120mm front intake fans in there if you make a few small changes but that's an entirely different subject. They even sell some that are only like 15mm thick that will fit in many places that standard thickness fans won't fit.

Here is the same thing, but with the glass panel off -

Also about the fans, if needed I can take more pictures of inside the case so if you could please tell me where exactly I could place them? They would make things even better :). I haven't mounted fans never, or even bought any.. so I don't know what mm would fit in there :)
 
So, temps look fine, but there is clearly something that isn't because your maximum all core boost frequency is showing as only 3.6Ghz and it should be above 4Ghz somewhere. Most the reviews show an all core boost frequency of like at least 4.4Ghz so something seems off there.

Could it be something, because of Power settings in Windows settings? BIOS? Maybe Armoury Crate App by Asus? Even though there isn't anything to change CPU related in there.

About the temps once again.. the fact that it runs 53-58 degrees on having youtube music on 2nd monitor and just this forum page open on main monitor makes me feel very weird.. like it's gonna damage the CPU? (Yes I remember NedSmelly saying that safe temp for this cpu is much higher.. but still)
 
Those temps are fine. Anything under 90°C max is within safe limits. Anything above that, is not. Idle or minimum temps don't matter much, only maximum temps. It can all day long at 80°C and it would be fine, but, boost clocks ARE related to temps so lower maximum temps often result in higher boost clocks or longer sustained boost clocks.

Yes, the power settings might affect that. Ryzen should be on balanced. It's also possible you might not have Precision boost overdrive enabled in the BIOS or another BIOS setting.

As for Armory Crate, I'd highly recommend getting rid of that. All those motherboard utilities from Asus, Gigabyte, ASRock and MSI do nothing but cause problems for most people. As for drivers, those should be updated manually anyhow. Armory crate is garbage and I'd uninstall it unless you absolutely have to have it. Even for RGB stuff there is usually an open source third party alternative that will work to control lighting so it's worth looking into if that is the only reason you use it.

I got Armoury crate only because of RGB, when I delete it the RGB just turns off. I haven't personally heard of other programs that can control them.

My power settings are on Balanced. I will check whether I got PBO enabled in BIOS, but what other options Have to be enabled?
And about the fans, could you help me and tell me where I could put them in the case? Thanks
**Also should I put the glass panel back on??

Ok I have to chime in. Are you looking at the correct column? I see >4.6GHz in the maximum column for core clocks

@HardGames323 imho this is kinda going off the rails for you. If you like the RGB then just run Armoury Crate - it’s an Asus prebuilt after all. I see nothing wrong with your reposted HWInfo screenshots, things seem to be boosting fine when reading the correct columns. If you still want to dig deeper into your ‘idle’ temps then please upload a screenshot of Windows Task Manager, Processes tab, sorted by CPU column. Cheers 🍻

Edit - also your minimum CPU frequency is around 3.4GHz all core, which seems high for doing nothing. Probably related to your chosen BIOS performance profile in Easy Mode.

You’re worried about your computer. I get it. I’d like to offer reassurance that, based on the info you provided, that things are OK and safe. For what it’s worth. Sure it’s not perfect to the standards of some enthusiasts, but that’s how it is sometimes with prebuilts etc. Let’s not unnecessarily escalate your anxiety.
