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.
Based on the award-winning NH-D14
Noctua's NH-D14 has received more than 350 awards and recommendations from leading international hardware websites and magazines, making it one of the most successful premium heatsinks ever built. With its expanded layout and dual NF-A15 fans, the NH-D15 further improves the D14's much acclaimed quiet cooling performance.
6 heatpipe dual tower design
s compared to conventional single tower heatinks, the NH-D15's fine-tuned six heatpipe dual tower design provides more surface area, better heat-distribution and superior airflow efficiency in dual fan mode.
Widened fin stack and expanded heatpipe layout
Compared to the NH-D14, the NH-D15's fin-stack has been widened from 140 to 150mm and its heatpipes are now spaced further apart, which allows for a more uniform heat distribution over a larger surface area and thus contributes to the NH-D15's superior efficiency.
High RAM compatibility in single fan mode
Thanks to its recessed lower fins, the NH-D15 provides 64mm clearance for tall memory heatsinks in single fan mode, making it compatible with most high end RAM modules on the market. In dual fan mode, the NH-D15 should be used with standard height RAM (up to 32mm).*
Dual NF-A15 140mm fans
The NH-D15 features two of Noctua's premium class NF-A15 140mm fans. Complying with Noctua's AAO standard and featuring sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A15 has quickly built up a reputation as one of the best 140mm fans on the market.
PWM support and Low-Noise Adaptors
The NF-A15 premium fans supplied with the NH-D15 support PWM for convenient automatic speed control through the motherboard. In addition, the maximum fan speed can be reduced from 1500 to 1200rpm using the supplied Low-Noise Adaptors for even quieter operation.
Excellent component cooling
Extending below the fin-stacks, the large NF-A15 fans not only contribute to the NH-D15's superb CPU cooling capabilities but also provide massive airflow over surrounding motherboard components and heatsinks, thus ensuring excellent component cooling performance.
SecuFirm2™ mounting system
Noctua's SecuFirm2™ mounting systems have become synonymous with quality, safety and ease of use. Supporting Intel LGA115x (LGA1150, LGA1151, LGA1155, LGA1156), LGA2011, LGA2066 and AMD (AM4 (since 2019), AM3(+), AM2(+), FM1, FM2(+)), the SecuFirm2™ mounting included with the NH-D15 guarantees perfect contact pressure and maximum convenience on all current sockets.
Compatibility with past and future sockets
Complying with the open SecuFirm™ standard, the NH-D15 can be made compatible with the older LGA1366 and LGA775 sockets using the optional NM-I3 mounting kit, which is provided by Noctua free of charge. If technically possible, Noctua will also provide upgrade kits for future sockets.
NT-H1 thermal compound
Noctua's much-acclaimed NT-H1 is a well proven pro-grade TIM solution that provides minimum thermal resistance, excellent ease-of-use and outstanding reliability, which makes it suitable for use in professional server and workstation environments.
6-year manufacturer’s warranty
Noctua products are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the supplied NF-A15's feature an MTTF rating of more than 150.000 hours and the entire NH-D15 package comes with a full 6-year manufacturer's warranty.
Efficient. Comes with 2 large fans with 120mm mounting holes. My case was wide enough but a bit of a problem installing second fan because of ram. I just used a regular 120mm fan instead. My Ryzen 5600x was running hot with stock cooler at 40 c idle and 90 c full load. Now it runs 2 degrees above room temperature at idle and 70 c maxed out stress test. Playing COD MW MW full out I peaked at 45 c. Comes with quality brackets Easy to install.
No weakness. Should fit into any mid tower gaming case with ATX Motherboard.
Very happy with product.
Incredible Air Cooled Solution

Amazing cooling capability
You need a good size case
When I rebuilt my PC last year I did not want to use my 5 year old water cooler so I looked at some alternatives as I didn’t want to go with water cooling again. This thing is a work of art and is huge so you need a decent size case. Noctua make the best fans (already have several) and let me tell you this CPU cooler is incredible. I have a i5-9600K overclocked to 5.0 GHz and the temps rarely hit the low 70’s. Most of the time they sit around 60 - 65. I only installed 1 fan on the cooling fins in the middle and used the 2nd as a rear exhaust and have never had any heat issues whatsoever.
If you want the bling of LED lights galore this might not be for you but if you want the best passive cooling option this is a no brainer. Would highly recommend.
