The Noctua NH-D15 is an iconic product in the PC enthusiast community and a top recommendation if you are looking for the best CPU air cooler. And now, the Austrian cooling solutions giant has finally released its eagerly awaited successor.

Recently showcased at Computex 2024, the new NH-D15 G2 is said to offer significant improvements in cooling efficiency, noise reduction, and overall design, making it suitable for both gamers and professionals.

The biggest change comes in the form of the NF-A14x25r G2 round-frame 140mm fans. Noctua is using a liquid-crystal polymer (LCP) called Sterrox to make these new fans as this material offers much better dimensional stability as compared to conventional plastics. The fans are also quieter while improving the overall cooling capability compared to its predecessor.

The NH-D15 G2 also features a total of eight heat pipes and redesigned asymmetrical fin stacks that combine to offer up to 20% more surface area. Despite having a height of 168mm and a width of 150mm, Noctua says that its new flagship should offer enough clearance for graphics cards in the top PCIe slot in standard configurations.

The cooler will now come with a Torx-based multi-socket mounting system for improved stability and ease of installation. Noctua will sell the NH-D15 G2 in three different versions: Standard, HBC (High Base Convexivity), and LBC (Low Base Convexivity).

The standard NH-D15 G2 features the same medium base convexity as most other Noctua heatsinks for optimal performance on AM5 sockets with the included offset mounting and on LGA1700 CPUs by using the provided washers or optional contact frames to mitigate CPU deformation caused by ILM pressure.

The HBC (High Base Convexity) variant is optimized for LGA1700 processors subjected to full ILM pressure or deformation from long-term use, ensuring excellent contact quality despite a concave CPU shape. Conversely, the LBC (Low Base Convexity) variant is tailored for flatter CPUs, providing proper contact on AMD AM5 without the need for offset mounting, and other flat CPUs (AM4, LGA2066, LGA2011) or lapped or custom flat heat spreaders.

The NH-D15 G2 cooler is available for $150, which includes an NM-SD1 screwdriver and Noctua’s latest NT-H2 thermal compound. To top it all off, the company will be offering a six-year warranty, making it a solid future-proof cooling solution for your PC.

What’s the biggest CPU cooler ever made?
DeepCool Assassin IV in a PC.

Modern processors keep getting hotter, and it seems like CPU coolers just keep getting bigger to accommodate them. There are some truly monstrous modern CPU coolers -- especially passive models designed to operate without any fans at all. It makes you wonder what is the biggest CPU cooler ever made? Is it one of these latest modern monstrosities? Or has a cooler from the past beat them to the punch?

I did a little deep dive into CPU cooler history to find some truly massive coolers -- and one that reigns supreme to this day.

I knew when AMD announced the Ryzen 9 7945HX3D that it would be a great gaming laptop CPU. It was even more clear when AMD announced it would release first in the Asus ROG Strix Scar 17, which is one of the fastest gaming laptops you can buy. I've tested it, and it lives up to AMD's hype. But I still don't think you should buy it yet. Let me explain.

Between reviewing desktop CPUs like the Ryzen 7 7800X3D and the Asus ROG Strix Scar 17 itself (read our Asus Scar 17 review for more), this new chip didn't hold any surprises. It's AMD's fastest laptop CPU, bolstered by the company's remarkable 3D V-Cache to boost gaming performance. It's a known quantity.

We don't see a ton of innovation in the world of gaming CPUs, but AMD's 3D V-Cache tech catapulted Team Red to the front of the best gaming CPU pack. And now, AMD is bringing that tech to laptops.

The AMD Ryzen 9 7945HX3D is the first mobile processor sporting AMD's 3D V-Cache tech, packing 144MB of cache on top of the chip to improve gaming performance. In addition, the processor comes with 16 cores, up to a 5.4GHz boost clock speed, and a 55-watt power design.
