[SOLVED] New Ryzen 5800x rig running hot

[Tangled in the Interwebs]

Hi everyone, I am a newbie to Tom's! My first question.

I recently built a new PC:
AMD Ryzen 7 5800X 8-Core Processor 3.80 GHz
Gigabyte X570 Aorus Master Motherboard
Crucial Ballistix DDR4-3200 64 GB RAM
Noctua NH-D15 chromax black, both fans mounted
1x exhaust fan, 1x door mounted side fan (~8" diameter), 3x front fans drawing air in

I am coming from Intel, so I am not sure what temps to expect. But, on idle the system is in the upper 60s to the mid 70s C, which seems hot.

What I have done so far:

• set aggressive fan curves that by the time CPU reaches 65, they go full blast. Still have these temps
• re-seated the Noctua... and used much more thermal paste than I initially used. I got the idea from reading an article showing that for Ryzen chips, using more paste shows better cooling. But after re-seating, the temp range is now slightly higher, tending more towards mid 70s C

I must admit, I am not sure how tight to turn the screws for the Noctua.

Right now, I only have Firefox and Outlook open while I write this post. CPU shows 67 C, but anything that tickles the CPU will send temps higher immediately.

Edit: using Ryzen Master software, I ensured that I am running the "Default" speeds - no overclocking, no performance boost. But still my speeds are running ~4600 MHz

How do I get my temps lower?
How tight is enough on the Noctua mounting screws?

Thanks!

Ok 60c in idle is a no no
Have you peel the warning plastic label bottom of your cooler that said "remove before using it"
are you sure that the cooler has touch the bottom of your cpu?
and no you dont get more performace if you apply too much thermal paste. The main reason why thermal paste was invented was to replace the tiny scopic gap in the cpu and the cooler. Metals are not always cut perfectly thats why theres those tiny gaps.

PSU: make, model, wattage, age, condition?

Check air flows. If you are pushing more air in than can be exhausted then the entire air flow cooling process etc. becomes moot.

Are you able to take some photographs of the case & fan arrangements.

If so, do so and post here using imgur. (www.imgur.com)

Hi Hunger, thanks for responding.

• yes, removed the label! just shiny metal there....
• pretty sure its touching. Not only did I double check to use the right spacers with the cooler, but there is some visible paste squeeze out.
• don't think I put too much paste on only a little squeeze out. but got you that above the "right amount" more isn't going to do better

I think I have all the basics checked here....

5800x (and other Zen 3 chips) PBO settings/Temperature fix

The 5800x is well known for having heat issues on stock settings, because it's single 8 core CCX design shares the same power limits as the 2x6 (dual 6 core CCX) 5900x - so it's got a lot less space to cool itself with. A big part of the problem is that motherboards will raise the maximum TDC...

Give this a look - at least the first 2 sentences, please.

When they stop, you stop. No elbow grease required.

Too much paste isn't as bad as some people are making it out to be - it's just a little wasteful, is all.
Excess paste is going to get pushed off the sides of the IHS by the mounting pressure.

Hi Ralston, thanks for the reply:

PSU: Corsair RM850. I researched it on part picker before buying to check that it is compatable and can provide power to the system.

Not sure how to judge if I am moving enough air through... per the gigabyte system info viewer I can see that all other temps are at 40C or lower in the unit, while PSU is at about 47C and CPU is at 65C right now while I am doing nothing on the unit except for looking at the SIV.

I will be able to take pics tonight of the inside. I am trying to keep everything unobstructed on the inside, plenty of space, and the case I am using is an old Corsair CC Carbide 500R - basically the front, side panel and top are all metal mesh. It is almost open-air.

Edit: the PSU is NEW and in just-installed condition. No damage or anything visible or obvious.

Phaaze, thanks for your response.

The link you provided is helpful... but I have not seen the "low temps" in the screenshots on that post, only when I am in bios. Then I see CPU temps of 35-40C. But never when Windows is running.

I will check that the screws are just at the "stopped" point tonight.

 

[Phaaze88]

Bios and Windows don't behave the same. The cpu has no need to turbo boost, or rush to sleep state, in bios either.

The first 2 lines from the OP in the link explains why the 5800X does what it does - it's not like the other 5000X models. They do further discuss how to get thermals down, to varying effects.
I linked that topic because of it's easy explanation about the thermals, and that you're one of many coming here and elsewhere about 5800X thermals going bonkers, even though there are bigass coolers on them.
A big old air or liquid cooler can't do much of anything when the problem lies under the hood of the cpu.

Yeah, I am feeling like there is nothing to do other than check that the cooler is screwed down evenly. Kind of disappointing, actually.

Is there any point in messing around with the settings, as that OP did? He's on water, I am on air.

You might get thermals down a little without reducing performance.
The thermals you see are well within AMD's specifications, but I suppose that's no real excuse for their crappy thermal solution under the IHS?

Air, water - doesn't matter, when some of the heat from the dies underneath gets lost in the socket before it can properly go up through the cooler.

 

[bprojectx]

Yeah I run into this topic a lot when researching for my girlfriend PC. It's a good starting point with great upgrade path in the future but the heat is the only thing that kind of putting me off. However, to justify for AMD, it's well within their "spec", but honestly a disappointing reason imho.

I guess there is nothing you can do or you can but insignificant, it is what it is, perhaps. Have fun with your 5800x, don't think too much about the heat issue, enjoy your rig 😀

Yeah, starting to get the gist of this. I think I am going to try making sure the cooler is tightened down tonight, take a pic for record here... but otherwise it seems like as long as I can get it below 60 C on idle, the range for this cpu is higher than I knew it would be. 😕

Got it. Well, will see if I can get it down a few degrees, but yeah.

 

[Ralston18]

Yes. Post the case photos when you can. Someone may spot something or otherwise have additional questions.

However, if the heat is an inherent problem with the 5800 then hopefully you will be able to manage that heat and avoid any related problems.

 

[Phaaze88]

Yeah, pictures might help.

Now, when some people suggest the 5800X as an upgrade, as opposed to a 5600X, 5900X, or an Intel cpu, in my mind, I'm like:
They'll be back here or there before long...

Plenty of room to breathe. I could prolly manage my cables better, but they are not constraining airflow. Added in an old USB expansion in the bottom PCIE slot for VR.

I played a little bit with Ryzen Master, and a drop of voltage - any drop of voltage no matter how small - instantly makes the temps drop into the mid 50s on idle with no other changes. But I loose the spikes of >3800 MHz boost.

I will have to mess around with the tweaking a bit more

I can't seem to get the imgur image to show properly when pasting the link.....

Link is broken. Even copy-paste didn't work.

Not sure how to fix that

 

[Phaaze88]

Oh, it works now. Did it fix itself?

 

[Phaaze88]

I'm not seeing anything out of place. 🤔
It looks good to me! The problem is just the cpu.

 

[mamasan2000]

Do you have any fans on the top?
The air around the GPU might just be going round and round before it is dumped on components higher up, like the CPU. You have sidedoor fan, 2 fans that look to be 120mm, PSU fan and GPU fan all competing for the same airspace. Is the sidedoor fan at least pulling air out?

On that case, it pulls air in, to bring fresh air, to the GPU. The case design is similar to my old CM HAF 932 Advanced.

It looks like this link works: https://imgur.com/a/G09qrah

Since I started this thread, I have followed up more on the heat issues with the 5800x. I am more of the mind that tweaking the voltages is going to have the greater effect.

But, I could reverse the side fan to flush air out, and I have a couple extra 120 mm fans to flush air out the top. But, as my prior Intel rig in the same case and fan setup as the current...I am guessing that the fan arrangement are not the primary cause of the heat. I might try out different fan arrangements once I get the CPU heat generally stabilized.

 

[Tangled in the Interwebs]

Hi all, Yesterday I did some work on the system.

Re-adjusted the Noctua ... One of the screws was bottomed out, the other one was pretty tight. I got slightly better thermals when I backed off the screws just a touch.

I investigated reversing the side door fan to flush air out. Unfortunately, the mounts on the fan are one way only. Also discovered I didn't have proper mounting screws to mount a fan or two on top of the case. So all that was a no-go, with what I had at hand.

But... I am thinking that adding more fans doesn't look necessary. After reading more of the reference material above, and researching youtube's covering the Ryzen heat issues, I tweaked my BIOS settings, lowering the heat output and getting better performance vs default values (as measured by Cinebench R23 scores). Cinebench increased 1000 points, and heat decreased by ~10 to 20 C!

Default CPU / out of box: VCORE: Auto, CPU Ratio: Auto, CPU VCORE: 1.2
Cinebench score: 13756, idle temp: ~69 C, Cinebench temp: 89 C, Prime95 small FFT torture test: system restart/exceeding 90 C

Tweaked settings: VCORE: Static, CPU Ratio: 44, CPU VCORE: 1.1875
Cinebench score: 14648, idle temp: ~50 C, Cinebench temp: 70 C, Prime95 small FFT Torture test: ~80 C after 5 mins

I will keep the current tweaked settings and use them over the next weeks, test them out IRL. But right now they appear stable and, as I write this note in Firefox (no other major work going on in background), my idle is 46 C, far cooler than the 60 C + temps I had when I started the thread.

Thanks to everyone who gave me suggestions!!

 

[Phaaze88]

That is a red herring.
An all core benchmark does not represent overall performance. Performance scales with how many cores are active at a time.
The cpu ratio of 44 will reduce performance when fewer cores are active.
