Ryzen 7 7800x3d Cooling Problems

[kapone32]

One of the things about the X3Dchips is that HW Monitor has many sensors for temp. You could have one core at 35 C and another at 50 on idle. Adding a GPU has also meant more power draw on X3D chips. If you disable the IGPU you might see a minor benefit. As long as you installed all components correctly you are Golden when you see higher temps than you are used to. I have seen the 80s in CPU temp with the at 100% but I have some Cooler Master SickleFlow 120s on that AIO and they are great for fan noise. Apart from that welcome to the X3D crowd. We are so popular that AMD releases on the non X3D chips are meh for the narrative. There is no doubt that X3D has had a major impact on PC Gaming, even today my friend called me and told me he almost pulled the trigger on a 5700X3D as his 3800X was showing it's weakness. We agreed that Black Friday is coming. I am looking for a 8600G (also bad for regular AM5) on a As Rock B650I(120hz DP and HDMI MB ports) I already have the RAM and Deepcool make good inexpensive PSUs. That is going to hook up to my Hisense 4K 120Hz Smart TV for some sweet retro Gaming.


So congrats on your purchase now you can enjoy high refresh rate PC Gaming. I personally love my chip. It is the first chip that has left me sated.

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?

Those temps are perfectly fine MS flight sim uses alot of Threads on your CPU at near max % usage as for CB it uses AVX512 which also puts your CPU under abnormal stress not considered everyday usage
mine gets that high too but it's still less than the 95 degrees C AMD will let it get to before throttling core speeds downwards
So you have nothing to worry about

throttles at 89c already. also noticed that with 85c it does never boost to max clocks. after i put in a d15 g2 noctua cooler it boosts to max with better temps

You'd hope with a ridiculously expensive air cooler a cpu that rarely breaks 85w and usually 50-60w would have ok temps lol.

I've stuck 40-50 usd coolers on 7800X3D and they've gotten nowhere near throttling.... Not sure what's going on with people's setups I picture a 30C room with a person wrapping their pc in plastic and saying look/look my temps are high lol.

I should say I never had issues keeping 5800X cooled even in meh cases airflow wise either and it seems people struggled with that one too I guess.

The only thing I can think of is amd tolerances for the IHS and sensor placement for the tdie readings must suck ass.

That's some pretty shit temps then if your using an 360 AIO it should be way cooler than that D15 all I can say is that mine is cooled really well with my AIO so maybe look at reinstalling it
+ if you don't need to use the onboard gpu then turn it off in bios also make sure you have the latest bios installed too as they've made changes to what soc voltage you get limiting it to 1.3V older bios's can push it to 1.45V which way more than needed which will increase heat to no end and can make them die early too

ok thank you so much guys

I have a few observations...

Even though this is only a 32 seconds session of HWiNFO its all I have for now...

1. You have indeed higher than usual CPU utilization (10-20%) and we can see this on task manager also.

2. The CPU sits around 50-55W total socket power (CPU PPT) and its justified by your CPU usage level.
I'm sure most users with AM5 CPUs and specifically the 7800X3D would see below 30W but this is on background tasks running and also the power settings of windows (low power, balanced, high perf)
Those can make the CPU "lazy" or "jumpy" regarding frequency boosting on each small or big load.

3. Because of the above, CPU cores are powered down (Core C6 residency) to a minimum. A lot of activity (C0 Residency 27-28%) going on, also shown by "Average Active Core Count" (2-2.5cores active out of 8)

4. Last but not least
I could say that CPU temperature (50-60C) is justified by all the activity going on but what concerns me is that CPU rpm sensor showing 1600rpm. Is this the radiator fans or pump?
I dont know how this AIO is supposed to be connected (for powering) to the board/PSU but I would double check it.
If your ambient/room temp is within reasonable levels then this could indicate either a not fully proper contact of the block coldplate to CPU IHS or maybe a pump low speed (if the 1600rpm is actually the rad fans).

 

[Lost_Troll]

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.

If in doubt, pull it apart and double check it.

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.

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.

100% agree once looking at the OP's pic's. The AIO should have an idle speed of 1000 to 1200 RPM speed. The fans at 800 RPM is fine for an idle speed.

that should be all, ty for the reply

You've got Windows update running in the background, and Brave is using a fair bit of your CPU (I wonder why). Other than that, everything's normal.

Not gonna look extensively into it but there are plenty of reports of it having both high cpu usage and ram usage.... Honestly never heard of it and that's why I googled it lol.

 

[FreedomEclipse]

Well, the thermal paste that Thermalright gives you is meh at best,

Actually It performs better than Noctua NT-H2. Thermalright bundle TF-7 with just about EVERYTHING

You can find out more about it here

As far as I know, Brave is a web browser for people who value data privacy so much that even Firefox won't do for them. Personally, I think privacy is cool, but I don't want to compromise on normal operation. With Chrome, at least I know that background tabs don't eat into my CPU.

I wonder if they send you a tinfoil hat in the mail after a year of using it.... JKJK

But yeah it looks like it's probably at least part of the problem small price to pay for privacy I guess.

Remount and tighten in a "star" pattern. In other words, top right 1-2 turns, bottom left 1-2 turns, top left 1-2 turns, bottom right 1-2 turns. Then repeat until all screws are tightened.
That ensures even pressure for your mount.

Set your CPU curve via curve optimizer's negative offset
Maximizing Ryzen 5000 Performance With AMD Curve Optimizer | HotHardware
Still applies to the 7800x3d.

If you are using XMP/EXPO, certain profiles will bump the voltage which causes more power consumption which results in more heat. One set of DDR5 6400 XMP kits i have idles at about 36w with max power savings set as the power plan in windows. A DDR5 5600 XMP kit i have idles at about 26w.

I have a large external custom loop, MO-RA3 420 with 4x 200mm Noctua fans at 100% RPM which is massive overkill and my CPU idles at 38-40c with a 31c coolant temp. Cinebench 23 runs at about 74c. Note that it is with ALL settings above, -30 curve optimizer offset and the DDR5 5600 kit installed.

Edit: I'm also running my PC on a BC1 v2 mini bench, not in a case. It's the ITX only version of this

which has exceptional thermal performance.

@Op can you put up a screenshot of the task managers startup apps tab please

One way to permanently reduce temps on AM5 chips is via lapping the IHS. Not for the faint of heart though & voids your warranty of course. But I have done it with my 7600X using Thermal Grizzley AM5 lapping tool (shave 1mm off) & have idle temps with a tower cooler of 31C in a closed up case ( MSI MPG Sekira 100R)
The dreaded extra thick IHS of AM5 chips is a curse but can be resolved by modifications either physically or electrically.

Another way to reduce cpu temps is to offset the Vcore &/or adjust LLC settings but some boards don't have both those options, this is apart from PBO tuning, that can come later. My Gigabyte B650 Aorus Ultra board for example does not have Vcore offset option but my other AM5 boards do.

There are ways to get around this problem.

80c++ would make me sweat my nuts already, I rarely even see my 13900KS on 6Ghz go over 36c while gaming and go over 60c while benching..(custom loop 480x60mm rads in use, direct die waterblock), though locals tell me idling in 40c and 80c load temps are normal for AMD..lol

I owned a 5900X and that statement went never true, my 5900X idles on 26c and just barely reaches 40c while gaming and while benching it would really hit mid 70c's on the same watercooling setup..

You cannot compare a 480x60 mm custom loop with any kind of "more accessible" cooling option. 95% of people don't do custom loops for various reasons. For them, 40 idle / 80 load is normal and within spec.

Brave is based on Chromium so both browsers should behave about the same.

Either way with ~15% cpu usage that explains the higher temps at 'idle'

If you're going to the effort of lapping the IHS might as well just delid and use a better one, with better TIM, the upgrade heatspreader from TG is good.

You can grit your teeth all you want, my 7800X3D still does BOINC fine at 82-83 °C non-stop 24/7 without any issue.

Custom loop cooling is a niche thing, unless every single AM5 CPU and Core i7/i9 is only meant for custom loop cooling.

I would say 99% do not use a custom loop

Don't forget, he also said "direct die wareblock"

If you looked at his pics in an earlier post, his cooler uses the existing AMD hardware to mount to.
Not 4 screws but two clips with screws.

and that kinda translate to 99% people complaining (or gonna complain) about the unusually high..ehem!!

I just find it illogical not to buy a comparable "worth" of cooling solution, when you (or everyone) can afford that expensive hardware upgrade.

What's illogical is wasting money on an overpowered cooling solution for an 85W CPU with little to no tuning headroom.

People with money don't grow it by wasting it. A decent air cooler performs fine with a 7800x3d, and there are near top end 360mm AiO options available for $60 (such as the FX360 Pro).

Custom loop is dead for people not running an intel space heater or people wanting the additional 2mhz in curve optimizer headroom you'd gain on a 7800x3d with a custom loop.

Hell someone may spend a ridiculous amount on a custom loop only to find the CPU won't do more than -10 CO due to silicon lottery.
