Table of Contents

It’s a great time to be a custom PC enthusiast: with new innovations like CAMM2 RAM on the horizon, and now Noctua has thrown its hat into the ring. With the new Noctua NH-D15 G2 release date revealed, the next generation of CPU coolers is officially on the way.

Noctua NH-D15 G2: Possible Release Window

It’s been 10 years since the original launch of the NH-D15 CPU cooler, and the fact that it’s still popular today highlights the hype for an updated model. Displayed at Computex 2024 this weekend, users won’t have long to wait. Three versions of the NH-D15 are due to begin shipping this month, from June 2024. A base NH-D15 G2, a Low Base Convexity, and a High Base Convexity option are all soon to be available to buy from select retailers. With one of the fastest turnarounds from revelation to publication (albeit with a decade between generations), this could be a great option for new PC builds.

Noctua NH-D15 G2 Specs

Having unveiled the new CPU cooler, Noctua is pleased to present the overall package that the cooler offers. Redesigned to allow for the best contact between cooler and CPU – meaning less cumbersome thermal paste (though it’s still needed), the NH-D15 G2 has a 20% greater surface area than the original model – with a temperature improvement of 3.2°C. Though that may not sound like much on paper, it’s sure to make a difference in practice.

Employing 8 heat pipes for more even heat distribution, the G2’s design philosophy is one of improvement rather than major change. There’s improved clearance from the PCiE buses, and the fans have been tailored for the most noise-free cooling. Noctua claims that this means the new cooler can maintain a solid 60°C at above-600W temperatures for extended periods, as long as 15 minutes. However, we’ll be waiting until we get our hands on one to properly benchmark it.

Additionally, there are a few quality-of-life additions we appreciate. AM5 users will be provided with a thermal paste guard, and though the design is broadly the same as the NH-D15, it’s slightly more compact and efficient. And whilst the NH-D15 G2 is launching with 240mm as standard, 120mm variants are due to hit the market in Q2 2025, meaning that there will be a new Noctua cooler for all PC builders.

In Summary

All-in-all, we’re keen to find out the final Noctua NH-D15 G2 release date, and we won’t have long to wait. Noctua is one of our favorite manufacturers of CPU coolers, so a refresh of an acclaimed older model is well worth the short wait!
