The NH-D15 G2 is the further improved second generation of Noctua’s iconic NH-D15. With its state-of-the-art, speed-offset NF-A14x25r G2 PWM fans, eight heatpipes and asymmetrical fin-stacks that have been carefully fine-tuned to work in tandem with the new fans, it achieves even better quiet cooling performance than its award-winning predecessor. As such, the G2 version is a true flagship model that continues the legacy of the original NH-D15 by pushing the boundaries of air cooling and rivalling the efficiency of many all-in-one (AIO) water cooling solutions. Optimised for relatively flat CPUs, the specialised Low Base Convexity (LBC) version provides excellent contact quality on AMD’s AM5 processors, even if the included offset mounting option isn’t used. In addition to its further improved performance, the NH-D15 G2 also offers enhanced compatibility thanks to an offset construction that allows it to clear the top PCIe x16 slot on most current motherboards. Last but not least, the G2 version has been upgraded to the Torx-based SecuFirm2+ multi-socket mounting system with included NM-SD1 screwdriver as well as to Noctua’s superior NT-H2 thermal compound. In short, the NH-D15 G2 has been further refined in virtually all respects from the heatsink and the fans all the way down to the mounting, thermal paste and accessory package, making it an ideal choice for customers who demand the best of the best in air cooling.
More performance, smaller size
Thanks to the higher fin density made possible by the new NF-A14x25r G2 fans as well as the asymmetrical fin-stacks and a slightly smaller gap between the stacks, the G2 version combines improved performance with a slightly smaller size compared to the original NH-D15 (9mm less heatsink depth, same heatsink width, same total height including fans).
8 heatpipes for superior performance at higher heat-loads
The NH-D15 G2 utilises eight instead of six heatpipes compared to the original NH-D15. The increased thermal capacity of the extra heatpipes is especially helpful at extreme heat-loads such as 250W and beyond, where the performance boost over the original NH-D15 is the biggest.
Two NF-A14x25r G2 fans
Noctua’s next-generation NF-A14x25r G2 fans set a new benchmark for performance-to-noise efficiency in round-frame 140mm fans. Their superb acoustics as well as their superior airflow and pressure characteristics are one of the cornerstones that enable the NH-D15 G2 to push beyond its legendary predecessor.
Specialised LBC (Low Base Convexity) version
The Low Base Convexity (LBC) version achieves optimal contact quality on relatively flat CPUs. As such, it is ideal for AM5 even if the offset mounting isn't used or if users seek to combine the lowest possible CCD temperatures with the lowest possible IOD temperatures. The LBC version is also recommended for AM4, LGA2066 and LGA2011 (-3) (free-of-charge NM-i20xx mounting kit required), direct die applications as well as CPUs that have been lapped flat or outfitted with flat custom heat-spreaders.

Next-generation performance
For an entire decade, the original NH-D15 was widely regarded as the best air cooler on the market. The G2 version continues this legacy by further improving the renowned quiet cooling performance of its iconic predecessor.

You get what you pay for. In this case, you are getting an air cooler that is literally the best of the best with refinement and attention to detail. My maximum temp on my Ryzen 7 9800X3D won't exceed 73 deg C and that is with the fans at 70%. Speaking of the fans, I cannot hear them and there are TWO of them mounted to this cooler. Even at 70% I still cannot hear them.I think the stellar performance is due to the fact this is a LBC cooler, specifically machined super flat with no concavity or convexity, so contact with the IHS is superb.Included are some very important accessories:1. Socket AM5 processor thermal paste guard/shield2. Noctua NH-2 thermal paste (as good as Arctic MX-6, but easier to spread)3. Easy to use off-set mounting solution that can also be used in "standard" mode without the 7mm AMD offset4. Low noise adapter cable, but you won't need it!NOTE: DO NOT use this with any Intel CPU. Intel CPUs don't have a flat IHS and tend to distort under their mounting pressure over time anyway. Get the regular NH-D15 G2 (AMD or Intel) or NH-D15 G2 HBC (high base convexity) for Intel specific applications.The only downside is the price. That said, the only way you will get a better cooler for your AM5 CPU is if you switch to water cooling and the issues that can come with.

Build quality is immaculate. Assembly instructions are simple and easy to follow, no missing parts. I used the offset position and had no clearance issues, fit was perfect I had 2mm of space between the cooler and my ram. As for the looks, it's Noctua lol I wish they had the black version out already. Cooling performance is superb (dropped 10°C in idle and gaming) paired it with some ptm7950 for an additional 3°C reduction. My 7800x3d idles at 46°C and almost never goes above 60°C while gaming, except for more cpu heavy games although i do usually aim for 120fps. In Call of Duty it does hit 70°C (highest temp for my games) but I am pushing 170fps. (Alienware Qd-oled ultrawide with a 4080) Also my pc is silent even under gaming and I have open back headphones 🎧. Good job to Noctua, as always.

Bästa luftkylaren som finns. Men den ger ändå bara några få grader lägre temperatur än sin föregångare.Så mycket pengar att betala för några grader svalare CPU

Prima di questo aio andavo ad aria avevo il famoso termaltake Phantom con 6 tubi di calore poi a il più performante e grosso termaltake assassin a 7 Tubi di calore, questo gigante ne ha ben 8 di heat pipe, le dimensioni sono portate al massimo possibile e un processore and 5900x overcloccato resta sotto gli 80 gradi sotto stress, con pasta termica artic 6 , termaltake tx 8 o termaltake tfx spalmata bene a caldo con l'aiuto di un asciugacapelli le ventole fanno poco rumore e si possono benissimo tenere al massimo anche con case aperto.Fa lo stesso lavoro di un AIO con case aperto, non ho mai superato i 65 gradi con nessun processore amd serie 5000 o 9000 con case chiuso ovviamente rispetto ad un radiatore a liquido in aspirazione da ambiente esterno ha 5-10 gradi in più. Il costo è alto ma dura una vita e non fa praticamente rumore perché le ventole sono più grandi e lente, meglio progettate. Fa più rumore un aio che aspira da dentro come molti li montano, che quindi deve fare andare andare più veloce le due ontre sue ventole, rispetto a questo. Inoltre un aio con radiatore da 280 o 360mm montato in alto in aspirazione da dentro al case chiuso col calore prodotto soprattutto dalla scheda video ha le stesse performance di questo ma con più rumore.

Könnte man 6 Sterne geben, dann würde ich sie geben.Ich hatte zuvor den Vorgänger, Noctua NH D15 S im PC, mit dem ich auch schon sehr zufrieden war,aber ich habe jetzt aufgerüstet auf den neuen NH D15 G2 LBC,und habe es nicht bereut, ja was sage ich, ich bin äußerst zufrieden !Der Neue kühlt jetzt im Idle und bei geringer bis hoher Last um schätzungsweise 5-6 Grad besser als sein Vorgänger, gemessen bei gleicher Lüfterdrehzahl als der Vorgänger,und ist dabei genau so leise, wenn nicht sogar noch leiser, als sein Vorgänger.Irgendwelche andere störende Geräusche (Rattel-Gate) bis maximal Lüfterdrehzahl konnte ich auch nicht feststellen.Ich betreibe den Nh D15 G2 - in der LBC - Version auf einem Intel LGA 2066 Sytem,auf einem Motherboard, Asus ProWorkstation X299 SAGE2 LGA 2066 mit einer CPU Intel Core i9 10940X mit 14 Kernen und einer TDP von 165 Watt.Es gibt im Internet Leute, die jammern daß dieser Kühler zu teuer sei,und vergleichen Ihn dabei mit verschiedenen billigst-AIO Wasserkühlungen, und manche sogar mit günstigen120mm Luftkühlern,und das passt für mich einfach überhaupt nicht.Denn, dass ist so, als vergleiche man den Kaufpreis eines Mercedes mit dem eines Fiat.Außerdem sind jetzt beim Neuem (Kaufpreis 150,-) jetzt 2 Lüfter dabei, der Vorgänger, der nur ca. 100,- Euro kostete, hatte nur einen Lüfter dabei, und das haben diese Leute, denen der Neue zu teuer ist, auch noch nicht "behirnt" !Mir würde es niemals einfallen, auf meinen mehrere tausend Euro PC, dann als letztes, eine billigst AIO WAKÜ. draufzu monieren. (alleine nur die CPU meines PC kostetet ca. 1000,- Euro !!!)Denn, jede Wasserkühlung wird irgendwann mal kaputt, (=Wasserschwund, Pumpendefekt) und dann ist auch die CPU kaputt, und vielleicht sogar der ganze PC.Aber ein Kühlkörper mit Lamellen kann nicht kaputt gehen, und sollte mal ein Lüfter kaputt gehen, dann läuft der 2te. Lüfter immer noch.
