Highcompatibility version of NHD15
Compared to the awardwinning NHD15 the Sversion uses an offset asymmetrical layout and a single instead of dual NFA15 fans. This allows the NHD15S to provide stateoftheart heatsink performance while maintaining superior RAM and PCIe compatibility.
Excellent RAM compatibility
Thanks to its recessed lower fins the NHD15S provides 65mm clearance for tall memory heatsinks making it compatible with most high end modules on the market. As the lower fins are recessed on both sides of the heatsink compatibility is excellent not only on LGA115x and AMD but also on LGA2011 where there are RAM slots on both sides of the socket.
Asymmetrical layout for better PCIe compatibility
As many current motherboards have the top PCIe x16 slot sitting close to the socket bigger heatsinks tend to block it. Due to its asymmetrical layout the finstack of the NHD15S is offset towards the upper edge of the motherboard when installed in standard orientation. This allows it to clear the top PCIe x16 slot on most current ATX and ATX motherboard.*
NFA15 140mm fan
Complying with Noctuas AAO standard and featuring sophisticated aerodynamic design measures such as Flow Acceleration Channels the NFA15 has quickly built up a reputation as one of the best 140mm fans on the market. button
Using the supplied extra fan clips the NHD15S can be upgraded with either a second roundframe 140mm fan with 120mm mounting holes such as the NFA15 for maximum performance or a common 120mm fan such as the NFF12 for improving performance while maintaining compatibility with RAM modules of up to 45mm height.
PWM support and LowNoise Adaptor
The NFA15 premium fan supplied with the NHD15S supports 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 LowNoise Adaptor for even quieter operation.
Excellent component cooling
Extending below the finstacks the large NFA15 fan not only contributes to the superb CPU cooling capabilities of the NHD15S but also provides massive airflow over surrounding motherboard components and heatsinks thus ensuring excellent component cooling performance.
SecuFirm2 mounting system
Noctuas SecuFirm2 mounting systems have become synonymous with quality safety and ease of use. Supporting Intel LGA115x LGA1150 LGA1151 LGA1155 LGA1156 LGA2011 LGA20110 & LGA20113 and AMD AM3+ AM2+ FM1 FM2+ the SecuFirm2 mounting included with the NHD15S guarantees perfect contact pressure and maximum convenience on all current sockets.
Compatibility with past and future sockets
Complying with the open SecuFirm standard the NHD15S can be made compatible with the older LGA1366 and LGA775 sockets using the optional NMI3 mounting kit which is provided by Noctua free of charge. If technically possible Noctua will also provide upgrade kits for future sockets.
NTH1 thermal compound
Having received more than 100 awards and recommendations from hardware journalists around the world Noctuas NTH1 is a proven professional grade TIM solution that provides minimum thermal resistance excellent ease of use and outstanding reliability. button
