Noctua NH-D15: new dual-tower flagship CPU cooler

Noctua NH-D15

If you are into computer hardware and overclocking, you probably know about the Noctua NH-D14. Its the most widely acknowledged and high-performance CPU cooler. It was launched back in November 2009 but still to the day, its one of the top dogs in the CPU cooling market. Noctua iterated it later on with better fans but the main design of the CPU cooler never got a change. Now with the new Noctua NH-D15, company is bringing forward a completely new cooler which succeeds the NH-D14 and holds the crown of being Noctua’s flagship.

Noctua NH-D15:

Noctua spent over 3 years in the development of NH-D15. Initially, it was expected to be launched in late 2013 but that obviously did not happen and Noctua’s answer to the delay is that they did not want to launch a half baked product. They wanted to get it 100% right.

Having convinced tens of thousands of quiet cooling enthusiasts around the globe, our NH-D14 has become a reference for top-tier dual tower heatsinks“, explains Mag. Roland Mossig, Noctua CEO. “In the end, it took us more than three years of continuous development, countless thermal simulations and over hundred samples to come up with a substantial improvement in efficiency. Staying true to our policy of not releasing anything we’re not 100% satisfied with, we had to accept some delays in order to squeeze out the last few percent of performance, but now we’re proud to finally release the NH-D15 as a worthy successor to the venerable D14.

On a quick look, the NH-D15 looks exactly like the NH-D14 but it is not. Noctua has widened the fins stack by 10mm to a total of 150mm. This increases the distance between heatpipes running through the fins resulting in a more uniform heat distribution among the fins. Furthermore, since the effective area of fins is also increased, they also get more contact with cool air resulting in faster heat dissipation. However, Noctua has not increased the number of heatpipes. The NH-D14, exactly like its predecessor, comes with 6 heatpipes which run through two towers of fins. Height and depth of the cooler is also increased by 5mm resulting in 165mm and 135mm respectively.

To help with clearance issues, the Noctua NH-D15 has recessed lower fins on outer sides providing 64mm of clearance in single fan mode for better memory compatibility. The NH-D15 ships with two NF-A15 PWN fans with 1500 RPM at max. They can be controlled with PWN controllers on motherboard and by the provided low-noise-adapters (LNA) which limits the RPM to 1200.
