I have a question about the CPU temp at 3930k

Hi I have a question about the CPU temp at 3930k
When you look at such as Aida64 is where 7 different types of temp.
1 pc only CPU
1 st named CPU Package
Then is there one on each core
My question is where is the temp diode on the named only CPU Where is it.
Is it the CPU or sits on the motherboard?

If you look at the picture that I have and you will see that I have two different temp.
A temperature of 21 C
A temperature of 31 C
Completely????
When I'm in the Bios and check the temp, it is sometimes 21 and sometimes 31
The temp is when starting from cold start.
Sometimes it settles at 21 C and sometimes at 31 C
This is????
10 degrees difference, My question is this the way with you? When you look at the other temperature limits are the same as always, it is only the first CPU that I am different (21-31) at various reboots.
If I just sit in the bios and save and restart and go into the Biso directly and check the temp no so it is in the example 31 degrees then if I save and restart a few times quite sudden as it stands at 21 degrees. Hm!! ??

Hey asard,

While I can not answer your specific question (still looking for answer though), I would have two question to you...

Are you using the latest version of AIDA64 (which edition do you have)?
Are you running any other temp monitoring software in the same time?

I'm not sure that I'll completely answer your question but following info should be useful for you (at least I hope it will)

"CPU temperature" itself is the temperature of the middle of the CPU's IHS.

In fact there's no temperature sensor (just like any other functional parts) in this place so you couldn't know it's real temperature. And you actually don't need that.

First of all you should know is the difference between CPU temperature (CPU Max temperature) and TjMax.
CPU max temperature or TCASE is just one of specifications that Intel posts in their press release. It's like Max TDP, some average value that they think the chip will/should newer cross (while being used on stock settings, without any OC)
In times of single-core CPU's, IHS had their own DTS and TCASE was the part of thermal protection system, and when reached it starts CPU throttling. Now, when CPU's have multiple cores TCASE is replaced with TjMax for this function.
For now TCASE is the temperature of CPU's IHS of CPU that was tested by Intel guys by stressing it to TjMax.

The thing that really matters is core temperature. Every core has personal DTS (Digital Thermal Sensor) and can be monitored easily.

So if you worry about your CPU's "health" look at core temp and forget about CPU temp)

Would it not just get hot cold anyways seems cpu fan is cooling it cpu will change temp up and down even if nothing is running ??? this is weird

Clocked to 4.5GHz

Im a girl 🙂 so be nice as i bite

If you are running two applications that poll the sensors there is a strong likelihood you are getting false readings. I do not recommend even having two applications that can measure or record temperatures installed on the same system.



The only temperatures that are meaningful to me are the individual core temperatures, the socket temperature is not relevant in my view.

Agreed!!! Core temp usually does this job well and dont install anything else. My view also.

Thanks to all who responded.
To all of you

I run with the newest Aida64 beta.
No other program.
Then it's not just in the windows I see a difference.
For when I am with you on your mind.
That is when I start the computer the first time in the day when it is cold.
Then I go directly into the Bios and check.
Here I see two different temp.
If you look then at each new start.
Sometimes 21 times Sometimes 31 So you see, this is already there in the bios.
Then if you start AIDA64 directly before the computer start to get warm so you can see where also different 21-31
I'm going to cut shots of the bios so you can see
What I think is questioning is that it's 10 degrees difference, I think it should be a just always at every cold start.

Well said great pack

The 21 and the 31 temperature are not important. The individual cores are.

It is very possible that a sensor is not functioning correctly, maybe a BIOS flash or switching to the B BIOS will rectify that. Do you get the same effect when you swap to the B bios?

What would be interesting is to see if you have different readings with another program. HWMonitor is a stand alone application, no installation. I trust HWMonitor far more than I do most other software that monitor hardware. More than the ASUS suite for example.

Give that a try and just ensure that you have terminated the AIDA service before you do.

My idea that there is a sensor that is bad.
That's why I ask you where the sensor is located?
If it is in the CPU or the motherboard?
Should The individual cores to be wrong, I would be worried.
But it is not.
The same always. I just watch some of you what you whims of it.
Once you've never set this before you become puzzled.
Like now when I started the computer from cold boot to a low of 27 C then 28 C, it is in when I look in Windows.
I BIOS flash the same one as
