Noctua showed off the second generation NH-D15 cooler at Computex. But the official launch is only now. There are several changes, including an increase in the number of heatpipes.
Cooler NH-D15 for many years it was among the best in the category of air coolers. In terms of features, this model matched a whole range of all-in-one solutions and was able to handle even top-of-the-line Intel chips, which noticeably heat up. It has long been rumored that a full-fledged second generation would arrive, and now this scenario is becoming a reality. The NH-D15 G2 is not just a copied successor. It brings a number of interesting novelties.
The cooler will offer eight heatpipes and an asymmetric design that has been tuned for optimal efficiency. The package includes two NF-A14x25r G2 PWM fans designed for quiet and efficient cooling.
Three versions of the cooler
The biggest novelty is the three versions of the cooler. Each of them has a slightly different curvature of the contact surface where the cooler touches the processor. Noctua reached for this solution by optimizing the curvature of this surface. Intel processors flex more, AMD less. A number of advanced users change the heat spreader at the chip, others have it bent after years of use. The compromise in the form of a moderately convex curvature works, but it is not always optimal.
First of all, it is necessary to mention that all three versions of the NH-D15 G2 are compatible with the current LGA1700 and AM5 sockets. Compatibility also includes older AM4, LGA1851, LGA1200, LGA1156, LGA1155, LGA1151 and LGA1150.
The NH-D15 G2 LBC (low base convexity) version is optimized for chips with AMD AM5 socket and low convexity. Even without moving the cooler off-center, the cooler on these processors offers solid performance, which is enhanced by the aforementioned displacement.
If you intend to cool only Intel chips, the NH-D15 G2 HBC (high base convexity) version is ideal. Intel chips bend more in the very center and this version ensures optimal contact between the processor and the cooler.
The basic version is then a compromise between the LBC and HBC variant. It will offer high cooling performance, offset mounting for AMD chips and, in LGA1700 chips, minimal deformation due to pressure distribution. So basically, the middle version is always a good choice.
Measurable difference compared to the first generation
And how are the resulting temperatures? At a load corresponding to 250 W, the second generation cooler can reduce the temperature by 3.2 °C. At temperatures up to 60 °C, the NH-D15 G2 can transfer up to 160 W of generated heat more.
According to the manufacturer, the NSPR score thus increased from 183 to 223 points. It is the first cooler from Noctua to break the 200-point mark.
Finally, here we have the values for fitting specific chips and versions of the cooler. Noctua specifically selected Intel Core i9-13900K (250 W) and AMD Ryzen 9 7950X (180 W) processors. Of course, independent tests will reveal more.
The price tag of all three cooler variants is the same and is around 152 euros, i.e. approximately 3,800 CZK.
