The D15/S are designed to work optimally with 140mm fans - for low noise and great cooling, could add a 2nd A14 and connect both with the LNAs. However if you have your fins set on 120mm spinners, check out the Darkside PWM GT s. The GTs are legend for strong airflow/static pressure at humane sound levels. Air cooler that would give better temps for my 13900K than Noctua NH-D15. *Using Core i9 13900K with e-cores disabled and all P cores clock at 5.6GHz with VCORE static set to 1.35 at LLC 6 on an MSI Z690 MEG Unify X motherboard. Now when running Cinebench R23 full load, temps hit 90C and average 90C and only go as low as 89C and peak as high as The NH-D15 allows for a RAM module height of 32 mm in its default configuration. The RAM clearance can be improved by moving the front fan up by a few millimetres. However, please note that this also increases the total height of the cooler, so please verify that your case has sufficient clearance as well. their third most-powerful retail CPU fan (only behind D15 and D15S. U12A is their second best retail cooler. If you look at the NSPR, you'll see U12A is rated higher than D15S. U12A is 169. D15S is 167. D15 is 183. In practice, U12A cools 7950x, for example, within 0.5C of D15. DJ_Marxman. • 6 mo. ago. I've upgraded from an i7-4790K to the i9-12900K a couple of months ago and have reused the NH-D15. While the previous processor was happily sitting at about 60 degrees at full load, the 12900K is quite a bit hotter, topping out at 90 (idle about 30 while regular workload seems to be around 50-60). I understand fully the 12900K is a power hungry The best performing fans on the market in terms of CFM and static pressure are (IMO) the Noctua A14 iPPC 3000s @160CFM. The D15 performs extremely well under 250W sustained loads, but struggles when you start to go north of 280W. The thermal performance also starts to stagnate when the fans push past ~2300RPM.

Using one fan only makes cooler slight less efficient. 1-2c difference at full speed under heavy load. The lower the fan speed the more difference there will be because 2x fans at half speed can overcome way more resistance than a single fan at half speed. Some reviewers found the NH-D15 to be slightly louder when using a single fan.

Like the previous model, the Noctua NH-D15, is placed among the top air cooling systems on the market, offering a very good performance being silent at the same time. The SecuFirm 2 mounting system is efficient, the cooler being easy to install, the average installation time is about 5 minutes. The accessory package is rich including all the

I know there’s already a lot of debate around this, but is it better to get a noctua nh d15 or an aio( a good 240/280mm for around the same price) for a 5950x? Reply reply DevAnalyzeOperate

The d15 is no joke. I know a lot of people think noctua has some hype. I really don't. Just the weight of the heat sink alone it's got quite a lot of thermal mass, and their fans are quite good and that cooler has a ton of flexibility. on cooling: I'm cooling a 13900kf, and it usually runs about 29-30c on idle, and up to low 70's while gaming.

The pattern on a 14900k with a Noctua NH-D15 air cooler. The NH-D15s bottom isn‘t flat. Noctua said me that the 14th gen CPUs are also aren‘t flat like former gens. Though igorsLab says the 14th gens are flat. Keep in mind that everything is manufactured with a certain margin of precision. Applies to the Noctua and CPU headspreader.
I use -0,030V. My 13700k tops out at 85c-90c during Cinebench, using 230w. That's with 5.4 all cores and a -0.06v offset. My NHD15 runs with a single fan in a case with terrible airflow. To me, that cooling performance is very impressive, especially given that the D15 couldn't handle more than 170w with the 7950x.
Recenlty i upgraded my MOBO + RAM+ CPU and kept the old noctua cooler NH-D15, thinking it will be good enough. After installation i noticed that, the CPU is thermal throttling when i'm doing the stress test in cpu-z. The odd part is that, the temperatures don't change, even when i'm keeping the side panel open.
If your case has good air flow, a NH-D15 should be more than enough for a 13900K. But really if you feel the need to upgrade beyond the NH-D15 you should maybe consider an AIO. I get they’re expensive, but if your getting a 13900K I would expect you would have the cash for a nice AIO.
