Noctua NH-U9S trouble cooling my 9700k

[Sorenson]

I just got the Streacom Da 2 and one of the best air cooling options for it is apparently the Noctua NH-U9s. I installed it on my 9700k, with all core sync enabled (only cpu setting changed), on my Strix z390-i motherboard. I tried playing a game of TFT and my CPU temps were getting to 80c. Am I missing something or is this cooler just not beefy enough to cool my 9700k?

depends on how much voltage MCE is pumping into the CPU, which is always too much

I figured it was that, I just didn't want to do voltage/stability testing -.- I'm not sure if I spend more time fiddling with my gaming PC or actually gaming on it. 

 

Do you think a corsair H60 would be better?

I fiddle with my PC more than I game on it that's for sure

 

but you could do it quick, just keep stress testing in 2 min intervals. If it's stable in P95 for 2mins, keep going down. When it fails 2 mins, add 0.05V to the last stable voltage and you're good.

Thanks, I'll give that a try when I get home. My only concern is that if it couldn't handle league at stock, then there won't be terribly much room for improvement.

Just disabling MCU will do wonders. But 80C isn't terrible. Not that good, but not terrible either.

I disabled MCU, turned off all core sync, and made sure the voltage was set to auto (I think, Asus’ bios is confusing to me). I was still getting really hot temps. I installed my h80i V2 that I was going to instal on my GPU with the kraken g12, and the temps in games are now down to 60-70c and it’s running much quieter. I might try a different air cooler, but for now I think I’ll stick with the AIO. The problem is, I can only fit really small ones in my case.

Have you checked what the voltages actually are? U9S is small cooler, so getting 120mm AIO is better in comparison.

My voltage is around 1.208 while in League. I put a - .005 voltage offset on the CPU and hooked the radiator fan directly up to the motherboard for better fan control. I have a support ticket out with Noctua to see if they have recommendations to make it work better.

Thats still bit higher than what it should be needing for stock clocks. But better than what it could be at worse (seen 1.37 volts with MCE).

Make it better? Its a small heatsink, it has limits even with fan running at full speed. If you were to install it back with current settings, MCE off and voltage controlled, results would be better too. Recommendation to make it work better would be to get bigger heatsink, U12S/U14S or even D15.

Thanks for the advice, I think i'm just going to stick with the h80i then and get a an h60 for my GPU if needed. I can't really fit a bigger heatsink in my case since it only accommodates air coolers up to 140mm in height.

Do you think this is acceptable? I'm running The Witcher at 4k here for 15 min.

dont see temperature of the CPU, but that voltage seems good for 4.8GHz medium load.

 

what did you do to the voltage/frequency curve of the GPU?

The cpu temps are at high 60s to low 70s. 

The GPU is set to max out at 1875mhz at .935v.  I just undervolted it to get the fan noise down.

actually better for performance if you lower the power limit to a number you like then pull the core clock slider to the right. It will automatically scale down voltage and frequency to meet your power limit settings.

How so? 1875 is where my gpu settles in after 10 minutes of gaming on stock. So I just found where I could run that stably with a manual undervolt. Am I missing something?

It just means the GPU power draw still fluctuates in different tasks. Say in workloads that arent as heavy in power draw, you're losing frame rates as it couldnt clock higher.

Your temps seem normal and are safe.

I'd say you're expecting too much out of that small cooler. 80c is fine, not great but fine. A larger cooler like the NH-15 will probably have the chip in the 60's.
