Thermal Throttleing With a Noctua NH-D15

[xxMega11xx]

I have a 5820K overclocked to 4.5ghz at 1.35v and whenever I put heavy load it goes to 4ghz or even lower. Temps are fine around 65C. Help

[ReHWolution]

Which temperature is 65 °C? Do you have a way of reading all of the cores temperatures?

Yes that is about on all cores and the entire package.

[ReHWolution]

What's the program you're reading your temps with?

What motherboard do you have?

Please, use a proper tool like AIDA64 (it's not free though) or HWiNFO64. AI Suite 3 sucks very hard. What about the VRM temperatures? It could also be power throttling.

I have the Asus X99 Deluxe

Ok I will try HWINFO64 and see what happens. The VRMs are at 60C as well.

In the bios, change the load frequencies. There is a frequency for 1-6 core load, so make the 4, 5, and 6 core frequencies higher. I had to change it myself recently on a Maximus board.

[ReHWolution]

Or he can just set the All-Core frequency to 4.5 GHz. That's much easier

[xxMega11xx]

@ReHWolution@fasauceome So my CPU is thermal throttling but I do not under stand why I did everything you guys had said and my cooler is beafy enough. It just doesn't make sense. The temps are like 87 and up.  

[ReHWolution]

X99 isn't easy to tame with air cooling. I had a 5960X and without liquid cooling I couldn't push it much.

Honestly, even with liquid cooling (a full custom setup) I couldn't keep it stable @ 4.5 GHz. Sooooo yeah, try to find a sweet spot between frequency and voltage, 'cause if you're gonna stay on air, you won't be able to get to 4.5 GHz.

I used to use a corsair h100i and I had the same issue and that is why I moved to the nocuta. Should I just tame the voltages and lower my frequencies

[ReHWolution]

Yeah there's not much difference between an AIO and a high end air cooler, honestly. Yes, I'd suggest you to dial down the voltage (around 1.25-1.27) and reduce your OC.

Is the cooler installed correctly so it's making full contact? What thermal paste are you using? Did you add enough? Whats the airflow in the case look like?

We had trouble installing the cooler but I believe it is installed correctly. The thermal paste is the stuff that is included with the cooler (it is quite good) and I put about a grain of rice and a half.

I have a cooler master Mastercase 5. Extremely good airflow

[geo3]

Then I would take the cooler off and check the dispersion pattern of the paste. It should cover the entire cold plate of the heatsink. If it doesn't then either the cooler wasn't making proper contact or your didn't put enough paste. It's been tested that adding too much is better than adding to little.

Case alone says nothing about airflow. Your fan set up needs to be considered as well. One way to test this is to take the side panel off and point a window or stand fan at the case. If that immediately fixes the problem it points to poor airflow.
