i9 9900k cooling with Noctua

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?

I get it. Thanks for explaining.

I am not much of an overclocker, but I will probably see how far it can go, and after that set it back on stock.

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

fan on the CPU block is quite - don't be fooled into thinking that difference in flow or the copper rad will make any difference.

I would run your NH-U12A and see what your temps are like first.

those noctua 3000rpm fans are stupidly loud.



if you want an AIO I would get the arctic freezer II 280 or 360mm.

Agree. I will test first with U12A and see what kind of temps. I'm getting.

Uhhh AC Freezer II with that little buzzer is just no way for me. It reminds me of that chipset buzzer on new AMD boards :D

it is the quietest AIO you can buy. The fan doesn't make any noise that you can hear over the other fans.

Sorry but saying it's the quietest AIO is simply not true. Besides, isn't it really a CLC? A Closed Loop Cooler with no fill port, threaded fittings, etc. so it can be to serviced, add water or repair if soming fails (almost always pump).

Kit Guru noise level in testing has it at 41.2dBA in 5th place out of 16 coolers including NH-D15 at 44.1dBA. Quietest is be quiet! Dark Rock Pro 4 at 39.2dBA and loudest is H100i V2 at 53.7dBA. Noise levels were taken at 1 meter distance which is industry standard. Interestingly TomsHardware review has noise level of 25.4dBA at 1 meter with other coolers tested maxing out at 28.2dB, which is quieter than a very quiet room (quiet bedroom at night 30dBA). There has be be about 3dB reading change at 1 meter for human ear to hear a change in volume, so total spread of 14.5dBA in aKit Guru's testing it's much varience. Other reviews show be quiet! Silent Loop coolers being quieter than Arctic Freezer II at 31-35.7dBA.

Any way we look at it Tom's Harware sound measurments are obviously wrong, and without any other reviews to compare with I'm not going to believe Kit Guru either.

My systems never go above about 40dBA. In fact they rarely go above 37dBA, and that's measured with a good sound meter, not a phone or similar My enviroment is typically 28-30dBA without talking, music, etc.

Is it worth in your opinion going from U12A to D15 ?

To me it would depend on how hot CPU is with NH-U12A and how well case airflow is. Might be worth finding out what the air temp into your U12A is under heavy load by using something like shown at end in below link:

AnandTech review has graph you can set voltage from 60w to 300w load. At 300w load NH-U12A is 15.6c hotter than D15 with delta temps of 44.4c and 28.8c delta. Add about 25c for air tem and that is 69.4c and 53.8c .. and 68.4c is well below maximum safe operating temp of most CPUs.
