Tailored to provide superior RAM and PCIe compatibility, the NH-D15S is an asymmetrical single fan version of Noctua’s renowned flagship model, the NH-D15. Thanks to its asymmetrical design, the NH-D15S clears the top PCIe slot on most µATX and ATX motherboards. At the same time, the single fan setup and recessed lower fins ensures 100% RAM compatibility with memory modules of up to 65mm height. Users who have sufficient room can also upgrade the cooler with either a 120mm or round 140mm fan on the front fin stack for further improved performance in dual fan mode. Topped off with the trusted, pro-grade SecuFirm2 multi-socket mounting system and Noctua’s proven NT-H1 thermal compound, the NH-D15S forms a complete premium quality solution that combines dual tower efficiency with excellent compatibility and flexible upgrade options.

Excellent RAM compatibilityThanks to its recessed lower fins, the NH-D15S provides 65mm clearance for tall memory heatsinks, making it compatible with most high end modules on the market. As the lower fins are recessed on both sides of the heatsink, compatibility is excellent not only on LGA115x and AMD, but also on LGA2011 where there are RAM slots on both sides of the socket. |
Asymmetrical layout for better PCIe compatibilityAs many current motherboards have the top PCIe x16 slot sitting close to the socket, bigger heatsinks tend to block it. Due to its asymmetrical layout, the fin-stack of the NH-D15S is off-set towards the upper edge of the motherboard when installed in standard orientation. This allows it to clear the top PCIe x16 slot on most current µATX and ATX motherboard. |
Dual-fan readyUsing the supplied extra fan clips, the NH-D15S can be upgraded with either a second round-frame 140mm fan with 120mm mounting holes (such as the NF-A15) for maximum performance or a common 120mm fan (such as the NF-F12) for improving performance while maintaining compatibility with RAM modules of up to 45mm height. |
SecuFirm2 mounting systemNoctua's SecuFirm2 mounting systems have become synonymous with quality, safety and ease of use. Supporting Intel LGA1200, LGA115x (LGA1150, LGA1151, LGA1155, LGA1156), LGA2011 (LGA2011-0 & LGA2011-3), LGA2066 and AMD (AM4, AM3(+), AM2(+), FM1, FM2(+)), the SecuFirm2 mounting included with the NH-D15S ensures perfect contact pressure and maximum convenience on all current sockets. |

High-compatibility version of NH-D15
Compared to the award-winning NH-D15, the S-version uses an off-set, asymmetrical layout and a single instead of dual NF-A15 fans. This allows the NH-D15S to provide state-of-the-art heatsink performance while maintaining superior RAM and PCIe compatibility.

Well, recently, I've been wanting higher cooling capacity than the 240mm radiator I have can offer... but I have no room for a better radiator or another radiator in my case - and my system needs to be reasonably portable. So my only option was to buy a case which could handle my system along with another radiator or two. Looking around, about all I could find was spending about $300 on the entire upgrade... for what would be a more difficult system to lug around. Much more money than I wanted to spend on this...
So, I figured I'd look around at what the best air cooling systems available and, naturally, came across the NH-D15 (and the S variant). After measuring everything, and as Noctua has already demonstrated their AM4 kit - and said it will be free - I knew this would be a rather safe way to guarantee early adopter compatibility... I grabbed the NH-D15S.
I didn't expect the cooler to work as well as my water-cooling setup, but I figured it'd work well enough to cover my actual needs - and I could hold on to my water-cooling kit for any time in the future when I really want to go all out and spend a fortune on a sweet rig that isn't going to be moving about. As it turns out, I was wrong. This thing works every bit as good as my custom loop did with it setup for reasonable acoustic performance.
Sure, I could crank my pump to 100% and my fans to 100% and the D15S would have no chance of keeping up, but this system is a foot from my head and I just can't stand the noise the pump makes over 50%. Using PWM, my fans were usually all at idle, as well as the pump, and they'd all ramp up with temperatures. I didn't want them ramping up while playing games, so I set the target temperatures to 60C for the fans and at 45C for the pump. The result was that my idle temperatures were about 35C on the CPU and the max temps were about 78C (i7 2600k @ 4.8GHz + ~0.015V), but could momentarily hit 80C.
The D15S, however, with just one fan, outperformed my water-cooling setup using the same PWM settings! Idle is at 32C and the max is 77C (using IBT @ Very High). What really got me was just how much more quiet this thing is than my rather quiet water-cooling setup. I added another fan to the D15S (a Cougar 120mm PWM fan) which keeps the highs down to 76C - so not much change.
Clearly, *IF* I go back to water-cooling, I will only consider doing so with much greater radiator surface area. which will require a new, expensive, case on top of the radiator and tubing costs... so I am having a hard time justifying such a move. I may well stick with air cooling... and what better praise can you give a heatsink than that?
Also, the install was simple, everything is very high quality, yadda yadda...

With the 15S I have nothing to worry and a very silent cooling tower with the performance to show. I had it stress run with 1.315 volt at 5 ghz all cores and never went above 80c. I used the thermal paste that came with it I plan to use artic silver 5 soon after typing this review or kyonaut.
Fits a Z390 Tuf Micro atx gaming no issues with clearance. Added another noctua 120m to the front with ease still quiet.

I ended up getting the NH-U12S instead, which worked fine, but I wasn't able to overclock the CPU as much as I would like. A few months later, Noctua announced the NH-D15S, and it is exactly what I needed. The NH-D15 touched the backplate of my first GPU, but the NH-D15S has a good inch of space the edge of the fan and the backplate.
For reference, I am using this with an Intel 5820K. With the NH-U12S I was able to go up to 4.2 GHz at 1.2 volts while maintaining temperatures below 85 C at full load (Intel XTU stress testing). After upgrading to the NH-D15S, I'm currently stable with 4.5 GHz at 1.275 volts with temperatures staying below 80 C (I haven't tried going higher than this yet). It was well worth the upgrade and my dream PC just got a little better :)

My cons have to do with installation. First off, the fins are very sharp, while this isn't unusual for heat sinks like this, the way you install it requires a pretty long screwdriver in order to get to the mounting screws between the fins. Fortunately, they do include a long screw driver tool, unfortunately, it's not quite long enough to allow your knuckles to completely clear the fins when turning the screws.
My second issue with installation was getting the mounting screws to line up properly so both could get a good initial "bite". If you got one side to grab, but turned it just a little too much, then getting the screw on the other side to grab is almost impossible. You have to alternate a teeny bit at a time between each screw, one turn too many and the screw on the other side would pop out of the hole and you have to start all over again. That combined with the too short screw driver led to s couple of bloody knuckles.
Would I purchase again? Meh, probably not. I'm not looking for insane over-clocks. I was happy enough with the performance of the Hyper 212, and while mounting those can be a bit tricky, it wasn't nearly as frustrating as installing this one. I would recommend anyone buying this to have a long (at least 8-inches, not including handle) screw driver handy.
