i5 6600 temperature jumps

Hello, I have bought an i5 6600 non k tdp 65w cpu 2 years ago(msi z170a tomahawk). Than I put good air cooling on that and observed the temperatures for the first month. Iddle at arround 24-26 degrees celsius, under a full load it went !slowly! up to 39-42 degrees. I was happy, I have built my new pc to be power efficient, cool and silent, as it sits in the living room and feeds the telly as well.

I have not checked the temperatures since, but about a month ago I did and I was suprised, how they jum from 29 to 50 degrees in just ONE second. Any small load causes that. When back to iddle, temperature goes back to 30 degrees in 2 seconds.

Now the temperatures jump up and down like crazy. CPUZ stress test puts it up to 60 after few minutes, it will not go any higher than. Do You think it is the thermal paste uder the lid?

Changing the thermal paste under the heat sink and cleaning had no effect at all.

Hello frantizsekk,

Thank you for posting.

Can you please provide the system configuration for your new PC built?

I have had no problems with the cpu temperature jumping up and down, when it was new. Now it is from 29 to 50 degrees in one second, it does not go any higher than 55-60, thanks to the cooler. I thin, that the thermal paste between the chip and the lid is bad quality and cannot transfer the heat fast enough after a period of time. Or, could that be caused after the security updates to your cpus? I have no other ideas.

It is not new, I have built that two years ago.

Thanks.

Let's check the temperatures with the https://downloadcenter.intel.com/download/19792/Intel-Processor-Diagnostic-Tool Download Intel® Processor Diagnostic Tool. It is completely safe to use this to diagnose your processor, download it and run the default test.

To attach a file, the "attach" option will appear in the bottom right corner of the response box.

I ran that test, all pass. Of course.. Temps did not go any high, it is a low tdp cpu and there is a good cooler on top of it. I could not save the file from that test to show everything, so just sending a picture. My problem is the teperature jump to 50 degrees in one second between no load and any load. That did not happen, when it was new. Temperatures moved up and down smoothly.

The temperatures captured by the Intel® Processor Diagnostic Tool are correct, and since the test was successfully we can confirm that the processor is not faulty.

Do you have any idea what could have changed the temperatures? Maybe a recent hardware or software change? Windows® 10 update?

You may want to check the following:

  • Double check that you are running the default settings in your BIOS. This to confirm that none of the settings of your BIOS are interfering with the temperature change.
  • Check with MSI if you are running the latest BIOS version.
  • Make sure you are running the latest chipset driver for your motherboard. Check with MSI for this driver.

Yes, all default and stock, latest bios and chipset driver. Same problem. Temperatures jump 20 degrees up or down in one second, depends to the load.

That is actually how I have spotted the temperatures, i was going to install a new bios version, 18 months after the purchase. Same problem before and after.

Here You can see that, when I stress the cpu and back to idle, how quickly they change.

Thank you for the video.

I understand that the temperatures while idling changed, but these are still running under the specification for the processor. The Intel® Processor Diagnostic Tool report is confirming this with the results you got.

Our recommendation in this case to double check that your Windows® 10 version is not related to this behavior. Additionally, you could check with MSI if a BIOS setting that might help to lower the idle temperatures. From, our your processor is working fine and under its specifications.

When idling, they are fine.Check the video once again, please. My question is still unanswered though: why do the temperatures go up by 20 degrees in 1 second, when it is under a load? They go back down to 30 degrees in one second, when the load is gone. Yes, the cpu works fine, passed the test, temperatures are ok as well. All ok, stock, new bios(default settings), new chipset drivers, win 10 latest updates etc. No processes/apps in the background(I keep monitoring cpu load, ram usage, hd usage and network speeds on my taskbar). When the cpu was new, temps changed smoothly and did not go over 36 degrees. I don´t think, that everything is fine, even when within the safe range. I keep asking that question since my first post.

Everything *is* fine. Why does it act like this? Well, because Intel cheaped out and used TIM instead of solder to connect the processor die to its heat spreader (lid). As a result, this generation of processors (amongst others) is thermally more volatile. That is, because TIM is significantly less efficient than solder in transferring heat, temperatures will increase more rapidly and to higher levels. This is my opinion; Intel will deny it - but the radical changes in temperature *do* occur and there are sites that have documented these differences in efficiency and there are posting here on the Intel Communities site that discuss this phenomenon.

Just saying,

Thank You, that is a logical explanation(or one of), but if intel deny that, I want to see them to get my problem sorted. I have paid this company for something, that is not working properly.

Hey, no one said it wasn't working properly. Intel is saying that there is nothing wrong and that it is perfectly normal for temperatures to be this volatile. I was simply adding that this volatility is the result of their decision to use TIM.

So it is a characteristic of this cpu, but you have to wait for it

There is no panic on intel, thought it is a decent company. My next MB and CPU will be AMD.

I have bought a new pc for my son, AMD, Ryzen cpu. Thanks to intel :]

My intel cpu will be delided, I will try a thermal pad instead of that cement from intel.
