Just wanted to make a thread to see what other people are using to cool there 9000 series CPUs. And what temperatures they are getting in trying to cool these CPUs.

I'm using the Noctua NH-U14S with two fans on the heatsink. On an i9 9900k right now.

And while gaming I'm getting an average of 65c in both Destiny 2 and Forza Horizon 4. This is with Asus MCE enabled and runs on all cores at 4.8GHz and peaks at 5GHz on all cores.

I've run Prime95 and temps can hit 80c. But haven't seen any throttling on the cores.
 
Temps don't seem high unless I run Prime, which is to be expected. My 8700k did the same.

With MCE enabled I was getting all core boosts to 5GHz with a NH-D15s, but obviously Prime pushed temps sky high.

Under water it idles around 24 or so and when gaming can be 40s max, again with MCE enabled. Ambient 17-18 ish. The CPU shares the loop with an Aorus 1080 Ti and the VRMs using a single 40mm 360 rad (3 fans total, pull), fans don't go over 1000rpm until i hit 50. No throttling. Leaving the PC on with tasks going in the background I see low 30s. This is stock motherboard fan settings in response to CPU temp.

I'm going to OC once I've got the PC moved in to the space I want it in. I haven't tweaked the fans and the loop doesn't monitor the GPU temp right now so while gaming the loop temp very slowly rises. It is kept in check by the temp rising on the CPU as the fluid temp increases but I will be addressing that.
 
With my current setup, it's fine. But I'm thinking if I want to overclock. Then I'm going to have to water cool my system.

I've looked at AIO CLC models, but they don't seem much better than the HSF that I already have.

eisbaer 360 only one i could recommend for aio- more the fact you can add gpu to it later or change it around to suit your tastes later on without breaking the bank
 
I'm on a custom loop with a fair amount of rad space. (1x360, 1x 280 and 1x140).

9900k at 5GHZ All Core. No avx offset.

Ambient temp of 23C

Prime 26.6. They generally sit around 69-72C. FFT of 1344
With small fft it sits at around 84C. This isn't really stable though unless I correct for Vdroop manually. (More below)

Realbench Stress Test, 16GB. Average out to about 82C, though one core hits 86C Peak.

OCCT Large Data Set average of around 66-67C. Spikes well up to 79 on one core though. Core 5 is a hotter one for me apparently.

However, I run water-cooling for quiet operation. So my fans are hardly what you'd call aggressive, spinning very slow. I'm also taking the voltage as low as I can go.

I'm running at 1.252V in the bios.
This shows as 1.243V VCore under load in hwinfo.

With the Prime 26.6 small fft the Vdroop is worse, something like 0.03-0.04v. I can't keep the small fft stable unless I correct for this manually and up my voltages.

Setting the LLC to a more aggressive setting makes it over volt significantly. Does anyone have a suggestion for sorting out the Droop? SVID is set to best case, and I have IA AC/DC loadline at 0.01.

Maximus XI Formula is the motherboard.

Edit : I have had to change the voltage for better stability when testing with Realbench.

Prime 29.4 (with avx) with small fft sky rockets my temperatures.

5ghz all core, no avx offset. GPU RTX 2080ti shares loop.
Hottest core:
Destiny 2: 59 (average 45-55) 1440p
1hr OCCT large: 62
1hr Prime95 avx: 85 (Coolest 79, may try reseat?)

All rads of the thicker variety. 360x2 + 240.

I am finding that I am getting better gaming temps than my 6700k at 4.7. Seems a lot less spiky. My 6700k using to have a bigger delta between average and hottest temp sikes.

I've started to run some tests myself. But still, need to get better cooling. Starting at 4.8 and 1.30v, and working my way up.

I watched this video guide by Der8auer earlier. Its based on the Asus Maximus so it was very helpful. As it has the same Bios layout as my Hero board.


Looking at my case and setup. I don't think a proper water cooling setup will be practical for me. So the Eisbaer is looking like the best option for me right now.

Thanks for pointing that cooler out to me Orbittalwalsh.

What is your system? Case, case fan setup, cooler, etc. Do you know what the air temp into cooler is while gaming for 30 minutes? Below is link to basic guide to airflow. At the bottom is image and short discription of how to setup a low cost indoor/outdoor thermometer to monitor airflow temp into cooler fans.

Corsair 450D case. Two 140mm intakes at the front. Two 140mm outlets on the top. And a 120mm fan at the rear. Running with a Noctua NH-U14S at the moment.

I'm looking at placing an AIO on the top of my case for better temps on the CPU.

Plus thanks for the link, I'll take a look at that now.

Try unplugging the top exhaust fans and removing all PCIe back slot covers. I'm guessing the cool air coming in from front intake fans is being drawn up and out the top as well as drawing the heated air up from GPU. Removing PCIe back covers gives case more rear vent area around GPU and with top fans not pulling air up and the front fans can push the heated air back and out of case and allow cool air to move to CPU cooler.

Thanks, I'll remove all the backplates first. As my vid card is an aftermarket cooler with three fans that keep the heat inside the case.

I've ordered an AIO cooler. So that will be sat where the two top exhaust fans are at the moment.

Please let us know how it works out. I learn as much from how others setup their systems as from the ones' I build. ;)

Well. After placing the rad and fans at the top of the case. With the rad fans bringing air into the top of the case. I now have four 140mm fans as intakes and just the one 120mm as an outlet.

But just by placing my hand over the rear of the case near the PCI brackets I can feel a lot of warm air coming out of the back. So there is much more positive pressure in the case.

Temps have dropped with the AIO fitted and I changed the ML 140 fans, with some Red LED ML140 fans. They can run at 2000rpm, but I don't have them at that speed of course.

So now running at 5GHz on the CPU at 1.35v. Still running some tests and tweaking too make sure everything is stable.

make sure the eisbaer pump is 100% ! alphacool recommend it and no reason why it shouldnt be, would be the most quietest part in the system :)

I didn't end up buying the Eisbaer. After looking at various pro's and con's I had two choices of either the Corsair H115i Pro or Kraken X62.

The Corsair won out of those two due to it's better software. But thanks for the advice all the same Oritalwalsh. :)

Hey Robin66, how have you found the temps so far with the H115i, I've got a 9900K arriving tomorrow and I'm a little concerned that I'll be using an H100i Pro in a mATX case (Corsair 240). I've seen reviews online where they reckon you need to have a 360mm AIO at the very least. If that's the case I'll need to rethink my motherboard/case/AIO.
