Question Unexplained high CPU temperatures and possible faulty readings ?

[InTheCity]

Hey everyone,

I'm reaching out to this community with a rather perplexing issue concerning my AMD Ryzen Threadripper 3970X CPU on an ASRock TRX40 Taichi motherboard. I've been experiencing some insane max temperatures (118°C max), and I'm starting to wonder if there might be a faulty reading somewhere.

Here's the situation: My BIOS temps idle at a comfortable 44°C, but once the machine boots up, the temps average around 70°C on idle. Under load, they can push to 95°C very quickly (no OC), with max temps I've seen reaching an astonishing 118°C while running Cinebench. What's even more puzzling is that there's no throttling or shutdowns happening at these temperatures.

The worst part? On a fresh reformat, idle temps are in the 55°C range. But after a few Windows updates, they jump right back up again.

Currently, I'm running Project Lasso and keeping all my non-essential processes on low priority. I've also underclocked the voltage down to 1 volt and the clock speed to only 3000MHz. This ensures that I don't routinely exceed that 95°C mark just doing everyday tasks.

Now, you might be thinking it's a cooler or thermal paste issue. Believe me, I've considered that. I've gone through four different coolers, and the last one was a professionally installed custom loop. It hasn't helped at all.

Monitoring in HWiNFO and Ryzen Master shows similar readings, with Ryzen Master being a few degrees cooler unless things get really hot. So I'm at a loss here, I'm concerned about possible faulty temperature readings, but I can't figure out what's going wrong.

Has anyone else experienced something like this with the Threadripper 3970X and ASRock TRX40 Taichi? Any insights or suggestions would be greatly appreciated. I'm eager to get to the bottom of this and ensure my system is running as it should.

Thanks in advance for your help!

Best

Hey there,

Is your bios up to date/? What version are you running? It should be 1.70 as a min. This may solve the issue.

What is the make/model of your case?
What is your cooling fan arrangement?
What is your ambient(room) temperature?
Do you have the ability to measure the temperature inside your case? (some multimeters have a temperature probe)

Does your setup provide adequate airflow over the motherboard vrm coolers?

CPU World shows the maximum operating temperature for the 3970X as 95°C and I'm reasonably sure the chip will start to throttle at this temperature. My first guess is to discount these abnormally high readings as false data. At a true 118°C I'd expect the BIOS to shut down the system.

If your custom loop is capable of cooling the nominal 280W TDP max ouput of the 3970X, with a bit of headroom for comfort, I think the readings from the thermal sensors in the CPU or mobo are being misinterpreted by your monitoring programs.

Do you know if HWInfo and Ryzen Master specifically support your motherboard's BIOS and the 3970X? They might only be calibrated for non-professional chips and not the Threadripper.

When I start up old versions of Aida64 on modern systems, I receive a message saying the motherboard is too new to be included in Aida's database. As a result, some data is missing in Aida and I treat other values with caution.

In the lab at work, I'd glue thermocouples on multiple hot spots to monitor temperatures inside the case, but measuring the CPU die temperature this way is not possible without cutting a channel in the CPU's IHS.

If none of your apps place as much strain on the system as Cinebench (which I'd only use for stability stress tests) and your system has never crashed with the CPU at stock voltage, I think you can disregard the alarming temperature readings.

My bios is 1.73 - Going to take care of that now. Thank you.
The case is a Corsair Airflow something or other. Flow is good; I have custom fan inside and an external fan I sometimes mount on hot days.
Ambient room temp is warm, about 76°c during the day at the mo.
There's an RTX 4090 in there, that never exceeds 70° - When that runs, the back of the machine blows out warm air.
Here's the catch, when the CPU is allegedly running at 118°, the air from the PC is cold.

Misgar, I agree with your assessment, it should shut down, there should be some ill effects from these temps.
I let them sit like that yesterday for at least a few mins. What's troubling is the last Windows updates pushing temps higher and higher.

With regard to Cinebench, I actually use C4D for work. Thankfully I do 90% of that work in Redshift (GPU render) and the Cinebench is obviously a CPU test.

Thanks for the advice, I'll report back if I have updates.

Good news. Updated the bios and it finally caps at 95°c - Still hot, but better than 118
Always wondered about the discrepancy in between Ryzen Master and Hwiw.
When Tctl is at 95 however, Ryzen Master is too!
My Fan Control profile is set to Tctl, because there's no better option. But it does mean my fans ramping up and ramping down all day long.

This seems like a good short term fix.

What about my clock down to 3200Mhz and 1.1 volt as a manual underclock?
When rendering, this keeps temps down to about 80° - And only slows down the machine a hair.

All temporary until I simply go back to Intel and get their 24 core CPU for $600. (slightly less power, but cheap)
This processor has been a pain in the a$$ for 3 years and still sells for $2500

I hope you meant your room ambient is 76F and not 76C.

I used to design equipment for 55C ambient air temp in vehicles without AC and we assumed that inside equipment cases the temp could reach 70C.

If you put your finger on the side of the water block, do you burn your finger? Does the coolant entering the radiator feel hot enough to make a cup of coffee?

Obviously there will be a significant temp drop between the silicon die and the water block, but it should still feel quite warm/hot to the touch, if CPU Tjunc is 95C.

Your GPU is running about 10C cooler than mine. My 7950X is sitting at 85C under an NH-D15 during a video render. Room is quite warm tonight around 78F. I run my hard disk fans flat out all the time.

Perhaps I'll skip the 3970X and buy a 5995WX if I win the lottery.
