Question Temperature of CPU is 60, cores 100? How can this be right?

Is my CPU overheating? I am running a i7 4790k at 4.0ghz. Not over clocked or anything. I have an H60 corsair cooler for it. Here is what it looks like when I play a game of overwatch start to finish:

I really don't understand, I would have never thought there was any problems by CPU temperature (which is always at 60 or lower during the game) but cores are hitting 100C?!?!

Is this just bad data from speedfan?

SpeedFan has a known issue with a 15°C offset in Core temperatures with certain motherboards, which means your hottest Core might be around 85°C. However, we can't be certain until you cross check your results with a know accurate monitoring utility. Also, many monitoring utilities will mislabel or misreport thermal values for various sensors, which can be highly confusing and misleading.

Since the i7-4790K does not have a "CPU" thermal sensor, SpeedFan has most likely mislabeled another sensor such as VRM and is instead calling it CPU temperature.

The monitoring utilities "Core Temp" and "Hardware Info" are frequently updated and known to be quite accurate. For simplified monitoring use Core Temp, but advanced monitoring details use Hardware Info (not Hardware Monitor or Open Hardware Monitor). When running Hardware Info, select "Sensors Only".

If these utilities verify that your hottest Core is actually running near "Throttle" temperature at 100°C, then the most likely cause is a failing H60, which prompts additional questions such as:

How old is your H60?

Is the radiator and fan free of dust?

Did your temperature problem seemingly occur overnight or gradually?

What is your ambient (room) temperature?

Hey, thank you for the detailed response. Didn't get a chance to get back to this til now.

I checked the radiator on my CPU, it was covered in dust, after cleaning, I believe the temperatures dropped. I barely get any stuttering now in Overwatch (less hardware intensive game). However, I still get stuttering in games like PUBG/rocket league/mordhau/others. I don't think it is related to the video card, I think it is more related to the CPU or RAM. I recently upgraded to a RTX 2060, thinking my GTX 760 was the reason for the stuttering. However, none of the stuttering went away, but my frames did go up in all games. When I cleaned the h60 radiator, the stuttering got better. So I think I am on the right track, but how do I make it all stop?

That is my PC currently. Do you think the stuttering could be due to the fact that the RAM might exceed the CPU voltage a tiny bit?

Also, here is a screen cap of coretemp after a few games of PUBG:

EDIT: To clarify, PUBG was still running when I took this screencap.

(also why does it say my frequency is 4.4ghz? I thought it was supposed to be 4ghz processor?)

Not sure why I am getting such high temps still... It might be throttling down if it is hitting 97 degrees C? Is there another part of PC I forgot to clean? the radiator had a TON of dust. Like it was filled with dust. I used a vaccum and compressed air to clean. I forgot to clean that in the past (I clean the PC somewhat regularly with compressed air) because I had to take the H60 fan apart in order to get to that dust. I didn't see how bad it was during past cleanings.

Also my H60 is 3 years old.

My room temperature is normal, about 72 degrees Fahrenheit. (~22 celcius) Might go up a degree or two during summer months.

"Throttle" temperature (Tj Max) for your i7-4790K is 100°C, so your frame stuttering problem is still due to excessively high Core temperatures. Here's the nominal operating range for Core temperature:

Core temperatures above 85°C are not recommended.

Core temperatures below 80°C are ideal.



Core temperatures increase and decrease with Ambient temperature.

Standard or "normal" ambient room temperature is 22°C or 72°F, so in that respect, your conditions are ideal.

The i7-4790K has a base clock of 4.0GHz. Turbo Boost is 4.4GHz. All quite normal and expected.

Testing thermal performance by running games or apps doesn't provide us with definitive information. You need to test your CPU the same way Intel does. There's an established and proper method to do so.

Remove case covers.
Manually set BIOS to run case and cooler fans, as well as the H60 pump at 100% RPM.

Download Hardware Info - https://www.hwinfo.com/download.php
When first run, select "Sensors Only". This monitoring utility will provide the detailed information we need.

Download Prime95 version 26.6 - http://www.mersenneforum.org/showthread.php?t=15504
Run Small FFT's for 10 minutes. This utility and test will provide a non-AVX workload which is steady-state with steady Core temperatures at 100% TDP.

Post your Core temperatures and CPU Package Power from Hardware Info's "Maximum" column. This will help us troubleshoot the problem.
