AMD Ryzen high Idle Temperature and faults discussion: 7800X3D 7900X3d 7950X3D

Hi Folks.  I'm going to try and be detailed as possible regarding high idle temps, specifically for my 7800X3D

For the first time EVER i have stepped away from Intel/nVidia and recently built my first all AMD PC with the following specs.

CASE:  Deepcool CH560 Digital (stock fan setup 3x140mm front Intake, 1x120mm rear exhaust) all controlled from mainboard
EXTRA CASE FANS:  Deepcool FC120x3 (1 intake in bottom of box, 2 exhaust in top of box) all controlled from mainboard
CPU COOLER:  Deepcool Assassin IV + Deepcool Thermal paste
CPU:  AMD Ryzen 7 7800X3D
PSU:  Asus TUF 850G ATX3.0 850W Gold
MAINBOARD:  Asus TUF X670E-PLUS WiFi
MEMORY:  Teamgroup T-Force DELTA 2X16GB DDR5-6000 cl38 EXPO
HDD:  Teamgroup T-force Cardea Z540 2TB M.2-2280 PCIe 5.0
OS:  Windows 11 home Ver. 23H2

You can see the build here:  https://pcpartpicker.com/b/3Rt8TW

Lets talk about Idle Temperatures.
After Build completed on 08/03/2024 I noticed from first boot that my idle temp for the CPU was sitting on 45c at bios (keep in mind windows was not even loaded at this point),  I instantly thought that i had seated the cooler wrong or something was up with the thermal paste application...  I then installed windows to make sure everything was running okay and so i could install various Drivers and software like ASUS Armoury Crate, GPUz, iCUE and specifically Deepcool Digital (the case has built in temp and usage monitors for CPU and GPU).  Low and behold the CPU idle is sitting at 47c on GPUz, iCUE and the Deepcool Digital.  So i re-installed and re-pasted my CPU cooler.  This yeilded the exact same results for temps.

It's since been as low as 44c but often sits around 46-47c.  After posting temps and asking around on PC parts picker ive determined that these CPU's can be as low as 30c when idling regardless of Aircooler or AIO with a rough average of between 35c-40c.  So I installed HWiNFO64 and Cinebench ready for some testing.  Looking under the CPU section in HWiNFO64 i noticed something odd, all the CPU core temps apart from "CPU (Tctl/Tdie) " and "CPU Die (average)" were about 36c-37c.  I though to myself how could the average CPU temp be 10c higher the actual temps of any or all of the cores...  It didn't make sense.  I also noticed around this time that Asus Armoury Crate had a dashboard with various senors and info showing the CPU temp to be 36c-37c...

Regardless i began a bench with Cinebench to see what temps would do using HWiNFO64.  I quickly reached 81c on the CPU (Tctl/Tdie) sensor at full load and saw a push until about 85c of which i set a thermal limit in Bios.  Clock speeds were ok but obviously throttled hitting around the 85c mark.  I checked Asus Armory crate temp to see it closer to 10c cooler than the average in CPUz or HWiNFO64.  Thats when i noticed what seemed to be causing the average of my CPU package to be 10c higher than all the other sensors.

In HWiNFO64 after the CPU section is the Motherboard sensors section.  The top 5 sensors in their are all thermals and they read:
Motherboard:  34c
CPU Package:  81c (same as CPU (Tctl/Tdie)
CPU: 70c  <10c cooler?
Temp9:  24c
TSI0 (CPU): 81c <<< This is the only sensor that isn't an average of other sensors

Turns out that the TSI0 sensor seems to be bringing my average temp up at least 10c sometimes 13c in some situations.  It is directly proportional to my overall temp, as in it completely governs the CPU temp all together.

Has anyone else noticed this causing them high readings, or even better does anyone know where to find this sensor on the motherboard?

I have already emailed ASUS support about the issue and i eagerly await their response.

Even if this doesn't really effect you, could you please post your CPU idle temps and CPU cooler model... it could help me get to the bottom of what's happening

ANYONE FROM AMD YOU ARE MORE THAN WELCOME TO COMMENT ON CPU IDLE TEMPS AND THERMALS UNDERLOAD REGUARDING THE TSI0 (CPU) SENSOR THANKS

Well at the time of this post my CPU idle temps are as low as 43c and looking at about 81c+ for 100% load pushing 5050Mhz on all cores max.  It seems that the discussion with Asus about the sensor in question was not very eventful and they don't seem to know which one i am talking about.

By all accounts there are some people with idle temps of 35c and some with temps of 45c and the only people with worries are experiencing high load temps (like 90c-95c range).  Getting my temps down i have moved 1 fan from exhaust on top of case and put it into the bottom of the case as an intake creating more positive pressure while also reducing my GPU idle temp from 40c to around 35c which in turn is dropping CPU temps faster and having them idle slightly lower.  I also adjusted my fan curves to kick the fans in at lower temps.  This makes a bit more noise but most of the time I'm wearing noise cancelling headphones and this build was more about effective air-cooling and gaming than a quiet PC that can cook steaks.

To anyone experiencing temp issues on the idle level I hope this small forum chat helps put your mind at ease.  I would have liked lower temps on both idle and load but technically they are well within the specified operating temperatures of the CPU...  If your struggling just do your due diligence with updates and different configurations and you can always hit the forums if something still seems wrong.

Have you flashed the motherboard BIOS to latest version? Last year ASUS and some other board partners were overvolting VSOC higher than it should with EXPO enabled, it is fixed in a later BIOS release.

Ryzen R7 5700X | B550 Gaming X | 2x16GB G.Skill 3600 | Radeon RX 7900XT

Sure have man, first thing i did before windows got installed i really want someone else with this mother board to chime in if they have seen the same stats...

HeyDoeAUD, you should be using Ryzen Master (RM)  to monitor temperatures and never run more than one monitor at  a time. Please post screenshots of RM at idle and running Cinebench R24. Please post images of only RM. Thanks and enjoy, John.

Ryzen Master unable to inititalize.  Kindly Reinstall the program.

Hence Aborting!

give me a bit and i will post some stats

excuse me misterj, any thoughts on the posted temps?  do you think they warrant further investigation as i do? you may see under full load 4.8ghz @80c.  I've seen full load temps (unconfirmed) as low as 70c for the same processor or even less,  also idle temps as low as 30c...  I'm not saying its a CPU issue i honestly believe its the sensor on the mainboard.  I posted a HWiNFO64 jpeg below showing my temps and stating my issues...  Any feedback or opinions are greatly appreciated

Armoury Crate CPU sensor is a board based sensor, not a readout from the CPU sensor itself. You can change the setting, or at least it was possible before. However, the fan curve will be adjusted from this unless you do it inside the board BIOS.

As for idle temps, check if the minimum processor state (inside windows) is set to the lowest value so it can step down when not needed, thus lowering idle temps as well.

Finally, curve optimize it to get the most.

7950X with a 240 Ryujin sitting idle at 35-38C HWiNFO64/Ryzen Master/Coretemp, they all show the same. Armoury Crate shows less.

Good luck

Thanks for the stats mate i really appreciate it.  See your temps of 35-38c seem much more reasonable for an idle CPU, anything sub 40c i feel is fair.  TBH im still thinking its a Mainboard issue.  Anyone with this Asus TUF x670e PLUS WiFi board getting same issues i wonder

My minimum processor state is set to 0%,  one of the first things i do in windows is set my Advanced Power options up for gaming.  I have HDD to never sleep and display never turns off also.  you think it would make a difference?

As far as curve optimization i tried a -30 from BIOS on all cores and it booted but never ran a stress test.  i have reverted all settings to normal for now as i thought having an all core undervolt doesn't really fix the high idle temp from stock.  kind of want to get to the bottom of this

Hi Team.

From yesterday got also some strange chooke on going at Forza5 or HL_Alyx in VR,

and desktop was not neough good that have safe setup cut-off main power when reach to close upper LVL Temp or PWR better to not make barbecue.

Hard reset log again, and again crash,

first GPU soft DRV of Nvidia core make crashed after that Steam core UI was hang and crash few times.

Get that feeling that MS IT guys make latest update and again they try to takfe control of segment that not should to not have when I decide to have other manufacture in this rule. 

not clear state of with one PWR Drivers MB Bus control MS Win or AMD ect my ASrock soft deal with it higher priority, MS thinks that they do it better when rthey sing green paper directives regulations fail Economic Distribuon Electronic devices to sell them on market with new sticker A+++ f...n ending story of magic economy line that save our planet - really who belive in this sh...t. put your finger in to AC socket and check if is safe.

Getting more redfined setup at BIOS again make more FAN's dynamic reaction earlier on temp try to jump so get no delay in droping peaks on some strange needs of OS - what for not doing OS take almost full load on 16 core of CPU make stable work go bounce - taking overload mahine wichout my permision to get values points as for handle own powering BUS rule as i predict on unknown process - kill some bushy loaded ones like

new "DEV Home" that appear just like that, i din't ask such one to on my system. 

Who and Why put it to my OS wichout my approvall - way of gettin in like infecting malware bugs. 

So point guilt as to be update for x64 processors package 20H2 few days ago - some thing like black hole - not sean & nothing known good about it but we know hidden do nothing special like free space blocking. .

Get fixed stability and CPU load drop down rapidly,  CPU and GPU temps are now even lower than before but is only that I redefine react graph points at dynamic set FANs RPMs via Temp relations to go earlier colling as in profile was.

Get faster fan spin with +400rpm on standard values with same temp -5deg. from basic profile. 

Maybe some one get use of it - in my case works with harmfull soft MS get off my system hidden tasks go out now permanently in best way hard way.

 **bleep** how i do not like those MS IT do some thing in way of make other users go no way to do some repair thier bad way to do any thing in any bad way of anything.

MS Help desk service is for IT MS team not for users help to go on. 

Take reverse undestanding U help solving issues IT MS team on service help desk site wroted - ar we now clear what is for Helpdesk MS web --- YEP real solution for profit cash at not their work distribution.

 

100% No Mistaques - Exist Only If 0% Work Is Done

well.  Not sure I am fully following you my brother.  anyone else able to help BartPP

No Bro I no need solution just got my case placed at some similar symptoms of crashing OS at no stress operations, got some removed updates from MS KB packages as always they got something more than supposed have on DLL files and all work of system gets pretty sick, after that system get back stable cool handling, so I fit rework at fan adjust vs CPU temp. time start to spin fans when reach some points got dropped than previous state so get think maybe some also can use this little Tweak OC on CPU and MB and GPU parameters. 

No need normally help from specialist - I'm kind of fanatic those toys so I will fix by myself take advance new problematic situations as challenge.   

But thanks for fast respone never can be so fast timing at Corpo MS HelpDesk service.

Haydn Durnin CPU temps.jpgI know everyone should only use Ryzen Master but check this shot of what i think is happening

CPU Package is the right temperature, the line bellow that says only CPU is the sensor i mentioned before, its not actually on the CPU. Thats what Armoury Crate reads and FansXpert will adjust the fans from.

I'll try to post a screenshot of mine once I get home.

The Englishman

Do you see the sensor I'm taking about down on the motherboard,  it seems to be the thing bringing my temps up as all the other sensor are at least 10c lower.  I have spoken to a few people on pcpartspicker they have similar temps to me though mine seems to be the highest I've come across.  i may actually take the 3 extra fans out and see if that makes a difference with a greater positive pressure. though i doubt it will...

Greetings bro,

 

I am facing the same problem with you. I build my first pc on 04-16-2024 with 7950x3d and a 360mm water cooler.

 

The idle temperature is about 45-50C with a room temperature of about 20-25C。When I open a webpage of a game (eg. Baldur's gate 3), the cpu Tctl will be up to more than 55 shortly. But the temp for cores are always about 10C less than that for Tctl. It seems that the Tctl sensor is put in a hot place. So I do not think the temp matters.

 

But when I look at the idle power consumption,it reaches more than 50W. 

 

I have tried all possible methods I can to low the idle power consumption but none of them works.

 

Could you please show your cpu's power consumption so that I can I can get a general idea of what's going on with the x3d cpu. If your cpu's idle consumption is not very high but the temp is high, that might indicate this is the problem of amd's design, which lead to the situation that the Heat collects at the top of the cpu and can't be carried away by the cooler. 

 

Best wishes.

Alot of it depends on ambient air temperature also. Example, If you are a cold bunny and keep it @75F in your house, your idle and load temps are going to be higher. The fans are pulling that air also to cool the system and through the radiator on your AIO. Would work the same with a custom loop also. But you will always get better cooling UNDER LOADS with a custom loop because the blocks / pumps are just better. You could stick a couple radiators in a bucket of ice and watch temps drop or I have seen someone build a bracket for a MO-RA3 and hang it out the window and extreme benchmark with his temps because of the gains.

I am running a 7800x3d and 7900xtx. I idle @40C CPU and 25C GPU and it is 69F in the house and 40F outside (Littleton, CO). After running a quick Superposition benchmark, no OC, CPU 63C, and GPU 39C. Now that EK 7900xtx block is the most badass on the planet. No matter what I do I have a hard time to get it to 50C, on a custom loop. Just as reference. To me these are the little things that separates the 10C everyone is looking for. And now you can de-lid the 7000 series to gain a little more on the CPU side.

1. Custom loop will always get better cooling. 

2. Ambient air makes a pretty big difference.

3. Remember, we are always talking about 10C difference. Everyone is always fighting and worried over 10C and as long as you are within the manufacturer's specs under full loads, who cares, don't worry, it will be ok. 

4. I tried to put a few ideas in here for anyone to try. I especially like the MO-RA hangar outside the window. You could gain -20C!!!
