Ryzen 7 7800x3d Cooling Problems

[sospicyy]

hi guys, i made a build last week and im noticing right now that my temps are kinda high.
I have mounted a ryzen 7 7800x3d with a thermalright 360 notte, with a total of 9 fans (two in the bottom, three on the diagonal, three on the radiator, and one in the back) my case is the h9 flow by nzxt.
My idle temps are between 55-65 degrees and with 10m of cpu stress test with cinebench and the 100% load i reached max 81.8 celsius. Yesterday i was playing at microsoft flight simulator and i noticed that my temps peaked 81.8.

I am sure that my thermalpaste is placed correctly and that there arent any stickers/plastic pieces on the radiator pump. Am i ok with that or i should maybe change radiator?

What is "idle" for you? All background crap closed? Your idle temps seem more like light load temps.

Your cinebench temps are completely fine, mine runs about the same, as does TPUs review unit.

Did you remove the plastic cover for the block?

AM5 chips run hot because they're dense and the heatspreader isn't great.

82 C is below throttle point so you don't have anything to worry about.

This is all normal for these chips. My X3D will skyrocket to 86c if I keep a full load on it for a while, but it never gets "hot" in day to day or games. You have nothing to worry about.

 

[AusWolf]

Your idle temp is quite high (are you sure nothing is running in the background?), but 81 °C at load is perfectly normal.

Almost any Ryzen CPU will peak north of 75C eventually.
And its more likely to reach 75~80+C on low loads and gaming than full (100%) CPU load.
With default settings that is.

For example my 5900X is peaking usually at 77-78C but under full load max temp is under 70C.

Peak temp is like spiking briefly, like frequency is spiking to max briefly. Those going hand to hand and its normal. High frequency bursts are happening so fast that the "produced" heat doesn't have time to reach the cooler. Heat dissipation needs some time to pass from core die to CPU heat spreader, to cooler cold plate and fins... and eventually to water/air
The peak °C you see under normal usage or gaming is probably not the temperature of the entire Core Die (CCD). There are small parts into the CCD that get hotter than others.
At least from Zen2 Ryzens are reporting those hotspots.

X3Ds are hard-er to cool because of the extra layer above the classic 8-core CCD.





If you run any full CPU load then I bet the temp will settle lower.
89C is your CPU max operating temp. If you get peaks at 80~85C but the average overtime is lower, you are more than fine.

Your idle temp is looking a bit high but that depends on your system settings on how true idle it is, and how fan rpm are curved with temp.

If you are willing to dig into your CPUs operating conditions then HWiNFO64 is your best friend

Other than temperatures you can look A LOT!

Like CPU core C-State Residency (States of cores)
C0: Active state
C1: Sleep/Parked state
C6: PowerDown state

Average Active Core Count: how many cores are active on any given time
PPT is whole CPU package power draw (Watt)
CPU usage

...to name a few

This screenshot below is 12hours mixture of normal every day usage and "idling".



To me all sensor readings have some value depending on what you want to see. And also min/max/avg values.

You can leave it on your tray running and use your system. The more you leave it the better.
If you want to see it during gaming sessions, click the clock down right and go into the game. When finish gaming (at least 1hour) take screenshot, save it and then you can study it.

For more accurate readings go to main settings (tray icon) and:

Also I'm not sure how accurate Tdie is anyways on ryzen 7000 seems amd set a large buffer to keep the silicon at a specific temp. They moved it with 9000 to make it more accurate allegedly.


Op Idle temps are slightly high but even just moving the mouse can jump you 10-15c on Ryzen. 81c is pretty normal on a 7800X3D on a CB load all 5 that I've worked with sat in the 78-83 range after an hour of blender on a 360 aio so yours is basically right dab in the center.... Without knowing your ambient and how good that aio is you sound fine.

I agree with others above there are plenty of data points of ryzen behavior it will boost to a specific temp right up to the thermal limit if allowed and every board is slightly different in behavior. Unless you are consistently over or near 85C it's a non issue if it bothers you set a lower thermal limit or lower your TDP.

My idle temps are between 55-65 degrees

Mounting problem.

 

[sospicyy]

yeah im sure, 13% of cpu usage with only brave open, my mins are 51.3 celsius and max 66.5, i dont really know why

Mounting problem.

can you be a little more specific please? It's my first build and I may have made some mistakes, but I installed the computer without problems, and the thermal paste seems good to me

 

[Lost_Troll]

I am sure that my thermalpaste is placed correctly and that there arent any stickers/plastic pieces on the radiator pump. Am i ok with that or i should maybe change radiator?

Well, the thermal paste that Thermalright gives you is meh at best, I used MX6 on mine. It also seems that you do not have the plastic cover on as the working temps seem too low, but I have seen it happen.

When you instilled the pump on the CPU, did you tighten the two screws with the springs until they had a hard stop? You do not need allot of force to do this, just go slow with the screwdriver while tightening them. I would check the other two brackets that mount on the motherboard as well, and make sure they are tight.

The other thing I would do, is enable PBO and do a negative under volt. It will make the CPU run cooler and clock higher longer.

Edit: Make sure that you have the pump power plugged into the correct port on the motherboard, and you have it set correctly in the BIOS. I would also setup a curve for the pump and fans.

 

[Laurijan]

Same CPU here and 43C idle temp. Cinebench goes up for me too to about 82C.
I bought an Noctua D15 G2 aircooler and used the included offset mounts for optimal baseplate position for new AMD CPUs. The offset mount kit is good to have (not a must) since on the AMD CPUs the dies under the heatspreader are somewhat in the south position and not middle.

 

[kiddagoat]

Your temps are fine. Mine will spike to 82C on occasion and I have an open loop on mine with a 4090. As others have said, it will keep itself in check. No need fixing what isn't broken.

 

[mc_Joe]

This situation is fine, many of the 78x3D have the same temperature status as you, so don't need to worry about that. I have seen lots of Ryzen 7000 series idle temperatures around 55℃, most users don't know what programs are running in their background.

 

[AusWolf]

yeah im sure, 13% of cpu usage with only brave open, my mins are 51.3 celsius and max 66.5, i dont really know why

13% usage is not idle. Idle is 1-2%. Something seems to be eating away your CPU's power. I'd monitor that if I were you.

 

[Blaeza]

Mine hits 85C in CineR23 with air cooling. But as I have been told, these chips are designed to be hitting those temps.

 

[thesmokingman]

Cpu with high idle is telltale sign of a bad mounting, ie. in your case your aio's cpu block. Idle should be around 30c w/o load, putting ambient aside. With a higher ambient that could swing upto 40c but even so you're into the 55-60s.

Yeah, but a 13% CPU usage is not idle. That's basically one core in full blast. I think that's the problem here.

Edit: Also, Zen 5 idles a bit warmish, especially with high speed RAM and a high VSOC. Around 40-45 degrees is quite normal.

 

[euphoria842]

I think that as long as your idle/low-load temp is within spec and is not thermal-throttling the CPU then you should not worry about it. You should really only care about it if you're having issues during intensive applications and high-load scenarios. I have my 7800x3d at 40-42c at low CPU load because I prefer having the fans in my case to be whisper quiet, only when I launch a game or something do they pick up and the temp stays in check to prevent thermal-throttling.

Mounting issues can be a lot of stuff.
Not correct tightening, wrong paste application...to name a couple.

But before you get into that and re-do installation other aspects need to be investigated first like...

Show us please a full screenshot of HWiNFO64 like what I've shown on previous post and also a task manager one like this:

You want to get to the bottom of this, you have to show us what we ask and answer questions we ask.
We dont have any crystal balls here that we can magically know what is happening

We spend time to think and write regarding your concerns.

You are fine

 

[freeagent]

I am not seeing anything that jumps out. temps arent that high, and look relatively stable. CPU has not seen very much load at all, so no heat. The potential for spiciness is there though..

i also used the mx6 from arctic, my pump is mounted into the cpu_opt slot in the mobo, and the screws should be tightened pretty good. I also got pbo enable at level 2 80. i was thinking about doing an undervolting

yeah thats why im asking, i thought that my aio wasnt mounted correctly, i just realized that my ring on the cooler can be the cause of the high temperatures, take a look at the photos it seems that it isnt fully in.

You have it in CPU opt but your rpm show your sys fans are at like 800rpm. The CPU fan is higher which I’m assuming are your rad fans going to the cpu fan header. This isn’t right though. You should ramp that pump up.

also please stop double posting. Edit your posts.

Edit: see if you can go into bios and modify the CPU_Opt header. If you can try maxing it out and see if those readings change. You should not touch the controls for your fans at all.
