Question High CPU temp at idle ?

[HardGames323]

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!

The first thing I'd do is ditch HWmonitor and switch to HWinfo. Much more accurate. More religiously kept up to date. Much less likely to incorrectly report sensor data or wrong sensors.

The idle temperature is clearly not normal, but "idle" is highly subjective as well depending on what you have running and what processes are running in the background. Also, virus or malware activity could have a real effect on what your resources are doing even when you think it's at idle.

More likely though is a cooler that is not capable enough for the CPU, a lack of airflow through the case or an improperly installed cooler.

What are your FULL hardware specifications including the CPU cooler, case fans, etc?

Also, any chance you purchased the three year extended warranty when you bough this?

• as you already know it's a prebuilt PC, so I really don't have any idea what the CPU Cooler is

Thanks for the reply.
About the warranty, Got it from another city in my country, a tech store - My Dad got it for me and he did buy an extended warranty - 3 or 5 years, I'm not exactly sure.
I saw other reviews about the same PC and a lot of people say that the stock coolers are bad and not enough. I tried setting up the fans to a faster speed, but it gets too loud. The loudness is not really that much of a problem, but I'm not sure which ones to set to what speed..

So the obvious but perhaps not most convenient option here would be to take advantage of the warranty if possible. Those temps are clearly not acceptable, although, it would be better to have some idea of what it's actually doing at the top end of the scale. Generally speaking the idle temperatures are mostly irrelevant EXCEPT when they are as high as yours are, and then it MIGHT indicate a problem. What matters most however is what happens under a full load.

Since it seems like you might not have a great deal of experience with the hardware side of things, as you are uncertain about the fans and what is what, it might really be a good idea to simply take advantage of the warranty or take it to a reputable repair facility that can take a look at your concerns for you. In truth, I think the problem is a poor case design rather than anything else and the fact that the AIO cooler is mounted in the secondary chamber without any form of intake fan whatsoever, as indicated by this review.

Asus ROG GA35 review: A great gaming PC with some clear oversights

The Asus ROG GA35 is a compelling option with how hard graphics cards are to buy. It hits the mark for a high-end gaming PC, but it still has some issues.

www.digitaltrends.com

There are some strange design choices, though. The all-in-one (AIO) liquid cooler is installed in the back chamber, exhausting air that doesn’t have an intake. It also causes the braided liquid tubes to lay awkwardly across the motherboard, which is a trend I noticed with the internal layout of the GA35.

The only included fan is a 92mm exhaust at the back of the case, and there isn’t space to mount any other fans.

Since there is no place to mount any fans, and since the only exhaust fan is a single 92mm fan, which is about as crappy of a thermal design as you could come up with, I honestly think your very best option would be to get a real case and move everything into that, and then add a couple more fans. Probably this would cure your entire issue. Your AIO is trying to use hot air in the case and your tiny exhaust fan is just not capable of removing enough heat for it to even matter.

Thanks a lot.. I really made a mistake buying this.
Is there a way to move the AIO to a better place in the case and something like that? Or a new case is a must? I need to ask my parents and then contact the store I bought it from. Thanks a lot, once again!

 

[Darkbreeze]

There is no way to move the AIO in that case. Like I said and like the review stated, there isn't even anyplace to mount any other fans and radiators can only be moved to locations where fans might have been mounted, generally in the front or top of the case, but that is not possible with this case. It truly is a terrible case design. The hardware itself isn't terrible, although we don't know the model of the AIO cooler so I withhold judgement on that, but overall, moving everything to a case where you can actually get some airflow going and get some heat out of the case is likely the only way to improve things in this scenario.

This is exactly the type of reason we highly recommend always either building your own system or having it built for you, because then you can choose each component and ensure that it can be configured sensibly and that things can easily be replace down the road if something goes wrong. With a design like this prebuilt has, you're pretty much stuck with what it comes from the store with and that's basically it forever aside from changing things like drives or memory or graphics card.

What case would you recommend? Also it will void warranty, right?

Also, I just found out that in BIOS, it says that Water pump+ is N/A.. Could it be installed incorrectly?

 

[NedSmelly]

Agree with @Darkbreeze , use your warranty and/or run it with the side panel off. Replacing the entire case is a good option if you're confident in your skills, but yes it would void your warranty.

Hi, thanks for the reply! You mean to remove the side panel and use it without it? I tried once, but saw a video of a dude smashing the window while carefully trying to remove it and I sketched out. Also do you know why my Water pump+ in BIOS is N/A ? Tyia

 

[NedSmelly]

Yeah I was also wondering if the water pump in the AIO had failed. In which case it's a warranty thing.

Yes just remove the side panel gently and run it open to the environment. If the temps drop significantly, then you know it's bad case ventilation.

Sounds like that video dude was an unsophisticated gorilla, unlike yourself

I will probably have to use the warranty if I can't find a fix for the water pump..
about the glass, the glass touched the desk I think and it smashed because of that

See how it goes without the side panel first. If idle temps drop, and HWinfo tells you the CPU isn't hitting 90C or higher under full load, then it's just the case ventilation.

But if nothing really changes, then yes it might be the pump at fault.

Edit: Had a look at a few review videos to familiarise with the case. Lay the case on its side, with glass panel facing up. Unscrew two screws adjacent to the glass panel on the back. Place your hands on the glass and pull backwards towards the I/O ports / rear fan - it should slide around 2cm or so. Now you can lift the glass panel off the case.

 

[Darkbreeze]

It might also be that the pump is not being powered via the AIO fan header on the board but instead is a model that simply uses SATA or another power source from the PSU for pump operation. Is there any monitoring software installed on your desktop for the AIO?

As for the case and panel, if you are afraid of taking the side panel off then there is probably very little chance that you are going to be capable or handy enough to want to try swapping all the parts out to another case, in which case, no pun intended, you might want to get a local shop or builder to do that for you. But I'd agree that taking off the side panel will probably help at least a little bit until you can pursue an actual fix like a warranty return or change of case.

What are you temps doing when you are not at idle? Again, I'd install HWinfo and I can explain, in great detail, exactly why I recommend ditching HWmonitor and installing HWinfo (After installing choose the "Sensors only" option when you start it up), and then see what the temps do when browsing, or running a game, or running some kind of stress test like Prime95 (Small FFT, all AVX options disabled), OCCT, Heavyload or even something like Cinebench, just to see what is happening with the core temps under a full load. If the temps at any point exceed 90°C stop the test and report back here.

Hello,
I uploaded some pictures, I got the glass panel off and had a look around the PC.
I also uploaded results of Cinebench (multi core test) and HWInfo next to it.
About the temps while browsing the internet, I have 1080p twitch on my 2nd monitor and I browse the web on my main, or I could be watching a 1440p video (with the 1080p twitch running on 2nd monitor 😀) and the temps were about 52-58max (also discord running on the background) no other heavy apps other than malwarebytes.
While the Cinebench multi core test was running, I touched both tubes of the AIO and they were vibrating, feeling something in there 😀. After the test was done, they were warm.. so that must mean it is working...
I uploaded also pics of the Fan cables and where they are connected, I tried unplugging some and plugging them in other ports (mixing them up) and nothing changed (I reverted them).
I don't know if the Temps shown in the screenshot were normal or actually good.. but why when I browse the web, which isn't a hardware heavy task.. my cpu gets to 70 degrees sometimes.
Also is it normal that if I for example open Steam and my temperature goes for 2-3 seconds to 68-69 and then it goes back to 53-55.
Should I change the thermal paste? A friend suggested.
ALL TESTS I MENTIONED ABOVE WERE MADE WITH MY GLASS PANEL OFF! ( I saw it dropped like 2-3 degrees at most, so the case isn't that bad?) Thanks a lot! I'm now worried if I should use my PC with such high temperatures just browsing.. till we find a solution

Edit: forgot the link

[Darkbreeze]

So, something doesn't seem right at all with what you're reporting.

Initially you said the system was sitting at 65-70°C at "idle". Then you said taking the side panel off allowed the idle temp to drop by about 2-3°C which means it would now be idling at 62-67°C. But then you say that browsing the web or watching a 1440p video your temps were "52-58 max" which is significantly lower than at idle, and honestly, not possible. Systems don't get cooling when they do more work, they get hotter.

What is the exact model of your motherboard? It should be printed directly on the motherboard somewhere.

In bios, it says GA35DX ver. 321
On the motherboard, it says "E148299"

Also, sorry for the confusion. Yesterday, I had been running the pc for 7-8 hours, so that's why it was probably warmer.

A friend of mine offered me his thermal paste by NZXT l, specifically: https://nzxt.com/product/thermal-paste-3g
Should I try it? Thanks once again

 

[Darkbreeze]

I don't think thermal paste is your problem, especially since most of these AIO coolers come with a preapplied thermal pad that is pretty much foolproof so long as the water block is installed correctly.

As for the motherboard model, none of those are the model. Somewhere on the motherboard it will say something like "TUF Gaming X570-Plus" or "X570-Pro" or "X570-P" or something along those lines. You can also try looking for the board model in system information. You can run that by typing msinfo32 into your start menu search box and hitting enter. Should list the board model there somewhere in the right hand side of the window that opens.

There really isn't much visibility of the motherboard, because of the GPU. In msinfo32 it says the same GA35DX. You can check this reddit post out: https://www.reddit.com/r/ASUSROG/comments/1bcgmj6/x570f_gaming_vs_ga35dx/
Looks like my prebuilt is a "modified" version of possibly X570F Gaming?

 

[HardGames323]

I also read that putting power setting to "Balanced" in Windows settings could fix potential overheating issues. Didn't really work. But putting it to Power Saving made my CPU temps stay at 45 degrees, I have no idea if it decreases performance while playing games though.

Edit: it does

 

[NedSmelly]

The temperatures shown on HWInfo in your pics look normal to me.

You think so? What do you think a normal temperature playing for example Hitman 3, Uncharted 4, GTA 5, and other games like that? (Highest settings) I'm getting quite worried of all this.. I'm thinking of making my Qfan settings in bios higher, is it worth trying it? Thanks Ned

CPUs are designed to hit 100C before they throttle. I wouldn’t worry about anything until a peak temp of over 85C is hit mid-Cinebench (or Prime95 stress test). You didn’t go above 77C so the AIO is doing its job.

Ryzen CPUs from 3000 series upwards just run hot because they turbo boost themselves during transient loads. So episodes of 60-70C whilst loading a busy website etc isn’t that surprising.

So after all this I’m getting the vibe that this might have been a storm in a teacup and we based our discussions upon incomplete info, until now. But at least you now know how to remove the side panel.

PostScript: in retrospect your “idle” isn’t really a true idle as you’re watching a stream channel and browsing. That’s actually quite a bit of processing work Involving video decode and JavaScript (amongst other things).

Yeah, at least I learned how to remove the panel.. So it's unnecessary to try putting a new thermal paste?

I have the HWInfo open on my 2nd monitor and just seeing how it goes to 68-71 degrees just opening something is very weird. All my Bios overclock settings are set on Auto by default, I hope that is not messing something up.

Also, should I try messing with QFan settings or no??

So you are saying that its normal for 5900x and that it will still handle very good with these temps everyday + more when gaming for a coupe more years? Let's say 4-5?? Possible? Thanks once again, Ned and everyone else!

Also sorry for a lot of stupid questions, I just want to learn and possibly one day give advice to people like me.

 

[NedSmelly]

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.
