CPU Temperatures Goes Crazy - i7-6700

Smily7 · Jul 9, 2016

Hello guys I bought my new PC week ago and last night my PC just freezed and the restart button didn't helped I had to turn the power off and then to turn the computer ON again.. Today this happened again like 2-3times. I realiesed that it can be an overheating problem. I downloaded some CPU Temp monitors and this is what I saw as a maximum temp of every core. http://prntscr.com/bqt4b5

In the right is the max temp and max value, in the middle minimum and in the left the temperature at the moment. I don't think this is normal.. I tried 3-4 programs for CPU temp and its happening again.. Sometimes when I just stay idle and do nothing just watching the temperature monitor I can see that its going up and down with like 20-30 degrees. I don't think this is normal and I can't understand what is happening.. Any suggestions ? Any ideas ?

What are you using for a cooler?

Is the fan turning?

Is there thermal paste between the heatsink and the CPU? Please note that you have to apply new thermal paste every time you mount the cooler.

I am using the stock cooler which came with the CPU and yeah it has a thermal paste on the heatsink. What you mean with the "Is the fan turning" ?

Those temperatures are high. Make sure the CPU fan is working correctly. Check the CPU cooler to see if it is securely mounted. If you're using the stock Intel cooler, one of the locking pins may not be pushed in correctly.

Smily7 :

There is a fan mounted to the heatsink array which is mounted to the CPU. Make sure it spins when you turn the computer on. If it is not spinning, then the heatsink will not be able to cool the CPU properly.

If there is no fan then we have a problem.

Smily7 · Jul 9, 2016

Oh you mean is the fan spinning, yeah of course it is spinning. I think temperatures higher than 80 is a lot

I usually say to keep it below 85C.

I also see from the image you posted that your clocks are all over the place? Do you have it set to downclock at low usage, or is that thermal throttling?

Smily7 · Jul 9, 2016

No I just captured it in that moment and after gaming. Here is now when im in GTA V .. http://prntscr.com/bqumc8 when I look at the temp monitor I can see that its going up and down with 10-15 is that normal I mean how can move around just like that with 15 degrees for a second.

Please consider getting a better CPU cooler. Something like the Cryorig H7 would work fine for you.

Temperature of the individual cores will fluctuate based on how much load they have (and not all cores are used or loaded the same) because the frequency and voltage will change. Since loads very, especially in gaming, so will the temps. But the 97C in your first screenshot is too high and your CPU is throttling.

i would repaste cooler and see if it is well seated on cpu your temp on load are to high and did you overclock it .

Smily7 · Jul 9, 2016

No I didnt. I don't think to overclock it at all..

scout_03 · Jul 9, 2016

then recheck cooler and repaste using mx 2 or mx 4 they do not need cure time .

Smily7 · Jul 9, 2016

My CPU is 5-6days old can I just repaste the cooler with the old thermal paste which was on the heatsink (stock) ?

scout_03 · Jul 9, 2016

then it still under warranty bring it back to the and complain about high temp they should fix it .

weberdarren97 · Jul 9, 2016

scout_03 :

Assuming he filled out the warranty card and didn't just throw it away like a lot of people tend to do

Smily7 · Jul 9, 2016

Okay I will try that. I have one more question. When I look at the CPU Temperature Monitor is it normal to jump up and go down with 15-25 degrees within 2-3sec ?

weberdarren97 · Jul 9, 2016

That would be representative of the cooler not doing it's job. The only time it should go up that quickly is when you go from idle to like a stress test or something

scout_03 · Jul 9, 2016

no it should raise up when you ask load on it should not go up and down like that .

Smily7 · Jul 9, 2016

Okay.. I'll call tommorow and talk with them about this. What you guys think about the normal temperature in idle ? 30-40 ?

scout_03 · Jul 9, 2016

on stock cooler that is good .

weberdarren97 · Jul 9, 2016

scout_03 :

I think you misunderstood... I meant that it shouldn't spike and fall like that unless you suddenly put a load on it (like running a stress test). But even then, the fall should be more controlled.

Smily7 · Jul 9, 2016

Okay guys I captured it. https://www.youtube.com/watch?v=n8XDHVik_tQ Don't skip just watch. Check this out and tell me if this is normal it's going from 40 to 60 within 2-3sec and its just crazy I don't know.. Im not a specialist but I don't think this is normal. I downloaded more than one applications to be sure but yeah. I am using a trial bandicam sorry for that.

weberdarren97 · Jul 10, 2016

That is really erratic... Wow

Have you reseated the cooler?

Smily7 · Jul 10, 2016

Yep I've done this last night I've changed the thermal paste and set it up on spot. I can't understand why the voltages are going like that and the frequency when im not doing anything im just watching the CPU temperatures (idle)..
