Hi, I am upgrading my PC soon with i9 9900k and MSI MEG z390 MBO. I have 6700k now with Z170 Extreme 4 MBO. And I am cooling it with NH-U12A with 1 fan. I know that i9 9900k is heater of CPU I already work with it, but I wasn't able to test it with air coolers, only AiO solutions. So I was wondering if my NH-U12A with push pull setup will be enough for i9 9900k CPU ? I will buy some AiO one day, but not in the mood of buying one these days, so I would like to use my air cooler if someone test it and can confirm that it's ok.


P.S
Any suggestions for AiO in future for that cpu ?

If you want run 9900k with a Noctua aircooling. I think you should change that NH-U12A to a NH-D15 what is the best of Noctua. AIO isn’t that much better even a 360mm radiator what NH-D15 is capable of. Those two are almost as same cooling capabilities around +/-2 degrees difference.

Customloop makes a big difference if you want overclocking all out of your 9900k.

If not going to overclock 9900k almost at all. That Noctua NH-12A will manage fine.

Edit. AIO H150i PRO RGB is 360mm and also worked fine for my setup earlier with push/pull configuration with 6 Noctua fans. I ran those fans with manual fan control panel so I could change speed rpm when need be. I do not know how other AIO manufacturers products work.

Thanks for your answer. Merry Christmas.

I know about custom loop that it makes a big difference, but I just don't have time for it now.

I won't overclock it, but I am worried if turbo boost kicks in on 5Ghz while playing or some heavy work, and U12A won't be able to cool it properly.

H150i won't fit in my case only 240mm rad. I have CM690 II so my only choice is 240mm.
 
You’re welcome and thank you!

If only 240mm fit in your case. Then your best option is that NH-D15 what also give overclocking option. 240mm isn’t that good, actually worse than Noctua in many tests. Doesn’t matter is it stock or overclocked.

I also got earlier Corsair 240mm, 280mm and 360mm. Still Noctua aircooler is more reliable than AIO and still Noctua performing better than AIO in temperatures. Only 360mm I could recommended if want AIO.

Merry Christmas!

As everyone told me U12A have same cooling performance as D15, even few Celsius better. Plus D15 is huuughe and I have high memories with heatsink so It won't fit, U12A have acceptable dimension.

Then you can keep that NH-U12A as well. Just follow the temperatures with HWinfo64 or Afterburner at real time so you know how tempetatures acting.

I’ve used many builds D15 and it kept all overclocked systems cool for me.
 

I saw that review, interesting. But Alphacool Eisbaer 240 AiO should performe way more better than that Artic AiO. It has Flow rate of 70L/h, and that Artic AiO I doubt it has anything near that.

P.S
Is that a little fan on the cpu block wtf. ?? No way for me with that little buzzer :D reminds me of this new AMD motherboards with buzzer on chipset :D

Did you test it to say it doesn't or you are just saying it like that.

It's the people who told you that the NH-U12A is better than the NH-D15 that are just saying it, or making a mess of testing. Luckily we have Noctua themselves stating that the NH-U12A comes close to the performance of big 140mm coolers but does not quite match or surpass their D15 or D15S.

1-2C higher comparing them is nothing. And it saves a lot space around cpu.

I have the 360mm version. I had the alphacool 360 lt before this. The mount on the arctic unit is miles ahead. The vrm fan is inaudible. Do what works for you.
 
I'll agree that the U12A has no chance of beating a D15 if you're talking about performance only, and neither has Noctua ever said this either. But what has always been the selling point of the U12A, is that you can get performance that is very close to the D15 in a much smaller (and much more compatible) package.

If I'm not mistaken, the U12A with both fans at high speeds should be able to allow you to run that CPU fine so long as you can get cool air to it and not trying to set world overclock settings on it. Something which isn't as easy to do inside a case however, especially the CM690 II that you're sporting as there's a lot of obstructions in the way inside that case.

I agree. That reveiw leaves a lot of unknowns, like actual air temp into cooler vs CPU temp. Results of any testing that does not record both air into cooler / rad at same time as CPU temp is taken can easily be off by several degrees .. even 10-20c if testing is done in a case with poor airflow to air coolers.

I also agree with posts about NH-U12A does not cool as well as NH-D15. While NH-U12A is quite good it is not as good as D15 and other top tier coolers. Below link clearly shows the difference. Even at 150w U12A is 3.4c warmer, and at 340w it's 15.6c hotter than D15.

OK point taken D15 is better than U12A.



Another question

What do you think about getting Alphacool Eisbaer 240 and getting some better static pressure fans ? I see that those coming with AiO are not that good with static pressure only 1.25 mmH20. Or do you suggest some better AiO ? Maybe Celsius S24 ?

What do you think about Noctua NF-F12 industrial PPC 3000 with 7,63 mmH20 ? Or you suggest some better fan ?

NF-A12's best performance balance.

You are talking about spending a lot of money on things you have no real nead for. U12A is plenty good for your application, even with some overclocking it will do very well. While AIOs like Alphacool Eisbaer are better than CLCs, they are still not near as dependable as air coolers and still cost way more money. So why spend a lot of money for very little gain?
