Noctua NH-D15 Air CPU Cooler Review

Introduction to the Noctua NH-D15 CPU Cooler

Noctua is a name that I bet the majority of our readers have heard of, being that they make a vast array of highly successful and quality cooling fans, CPU coolers, and thermal pastes. Noctua’s premium products are aimed at those who seek reliable coolers that provide extreme and quiet performance, so the cooler that we’re going to review today has some high expectations. Designed off of the highly successful NH-D14 cooler, the NH-D15 was born and tweaked for improved performance.

“Built on the basis of the legendary NH-D14 and carrying on its quest for ultimate quiet cooling performance, Noctua’s flagship model NH-D15 is an elite-class dual tower cooler for the highest demands. Its expanded heatpipe layout and two premium grade NF-A15 140mm fans with PWM support for automatic speed control allow it to further improve the NH-D14’s award-winning efficiency. Topped off with the trusted, pro-grade SecuFirm2 multi-socket mounting system, Noctua’s proven NT-H1 thermal compound and full 6 years manufacturer’s warranty, the NH-D15 forms a complete premium quality solution that represents a deluxe choice for overclockers and silent-enthusiasts alike.”

The NH-D15 is a massive air cooler with nickel plating throughout, featuring dual cooling stacks with six 6mm heat pipes running through them. This dual tower heatsink will provide more surface area, better heat distribution, and superior airflow when utilizing two fans. The copper heat pipes between the two cooler stacks are shared and run through a copper cold plate.

Attached to the cooling stacks are either one or two – depending on the space availability in your chassis – NF-A15 140mm PWM fans, which are capable of pushing 82.5 CFM at 1500 RPM, producing a mere 24.6 dBA. The static pressure was not listed on the D15 product page, however the NF-A15 page states 1.51 mmH2O at a different (lower) RPM and CFM spec. If the 24.6 dBA noise level is too much for you, you can tame the fans with a low-noise adapter (LNA). The LNA will drop the max RPMs to 1200 at 19.2 dBA.

The NH-D15 features a widened aluminum fin stack, when compared to the D14, widening the stack from 140mm to 150mm. In turn the heat pipes are placed farther apart in the stack, with the end result being more uniform heat distribution over the now larger surface area.

Mounting this cooler will be made easy thanks to the SecuFirm2 mounting system, and in this review you’ll see exactly how easy it is. You will end up mating this cooler to your system with Noctua’s NT-H1 high grade thermal compound.

While the NH-D15 has been out on the market for over a year now, we wanted to see how it faired against some of the modern air and liquid coolers you find today. Will it set the bar high for the air coolers that we’ve recently reviewed, or will it get into the liquid cooler territory? Those are answers that we can’t wait to find out!

You can currently grab the NH-D15 for $93.04 shipped on Amazon, which this cooler includes a whopping 6-year warranty!

    ¡Excellente cooler!, sobretodo en el acceso a memorias RAM; fácil instalación con accesorios de excelente calidad; ventiladores de larga vida útil de 4 pin; viene incluido un destornillador muy bien pensado para la ocasión; nada que envidiar a los cooler hidráulicos (está a la altura); está diseñado de tal manera que puede refrigerar eficazmente el Northbridge de la placa madre; sus ventiladores pueden ser instalados a diferentes alturas y lugar.
    Mantengo mi CPU AMD FX 8150 a 20ºC en invierno y en verano a 26ºC, con los dos ventiladores instalados.
    Soporta mínimo 16,5cms de profundidad de gabinete.
    Nada que decir, totalmente recomendado.

    Saludos
