Successor to the award-winning NH-C14, the NH-C14S is an elite class top-flow CPU cooler that is extremely efficient, highly
compatible and remarkably adjustable. Thanks to its deeper fin stack and the renowned NF-A14 PWM fan, the single fan
NH-C14S provides similar quiet cooling performance to its dual fan predecessor while being even more versatile: With the fan
installed on top of the fins, the cooler is compatible with RAM modules of up to 70mm height. With the fan installed underneath
the fins, the total height of the cooler is only 115mm, making it suitable for use in many HTPC cases. At the same time, the new
offset layout allows it to clear the top PCIe slot on most µATX and ATX motherboards. 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-C14S is a premium quality top-flow solution for the highest demands.

Based on the award-winning NH-C14
Having received more than 200 awards and recommendations from leading international hardware websites and magazines,
the NH-C14 has become an established reference for 140mm top-flow coolers. With its deeper fin stack and more efficient
NF-A14 PWM fan, the new S-version provides similar performance and further improved compatibility.
C-Type top-flow design
The c-type top-flow design of the NH-C14S not only allows for superb quiet cooling performance while maintaining a much
lower profile than today's 140mm tower-style coolers but also ensures excellent airflow over RAM modules and near-socket motherboard components.
Low Profile Mode
Run with the NF-A14 fan installed underneath the fin stack, the NH-C14S stands only 115mm tall, which is much lower than
tower coolers with 140mm or 120mm fans and allows it to fit many desktop style or HTPC cases.
High Clearance Mode
Run with the NF-A14 fan installed on top, the NH-C14S provides extended clearance underneath the fin stack. This way,
it is fully compatible with chipset coolers and RAM modules with heat-spreaders of up to 70mm height.
Offset design for PCIe clearance
Compared to the original NH-C14, the layout of the NH-C14S has been offset in two axis. Thanks to this measure, the
heatsink will clear the top PCIe slot on most µATX and ATX motherboards when the bendings of the heatpipes face the PCIe
slots or the I/O panel.*
NF-A14 140mm premium fan
Featuring sophisticated aerodynamic optimisations such as Flow Acceleration Channels, the NF-A14 is renowned to be
among the best quiet 140mm fans on the market. Combined with the deeper fin stack of the NH-C14S, it allows the cooler to achieve similar performance levels as its dual fan predecessor despite only using a single NF-A14.
PWM support and Low-Noise Adaptor
The NF-A14 premium fan supplied with the NH-C14S 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 Low-Noise
Adaptor for even quieter operation.
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 (LGA2011-0 & LGA2011-3), LGA2066 and AMD (AM3(+),
AM2(+), FM1, FM2(+)), the SecuFirm2™ mounting included with the NH-C14S guarantees perfect contact pressure and
maximum convenience on all current sockets.
Compatibility with past and future sockets
Complying with the open SecuFirm™ standard, the cooler 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
Having received more than 100 awards and recommendations from hardware journalists around the world, Noctua's NT-H1 is a proven professional grade TIM solution that provides minimum thermal resistance, excellent ease of use and outstanding
6-year manufacturer’s warranty
Noctua products are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the supplied
NF-A14 features an MTTF rating of more than 150.000 hours and the entire NH-C14S package comes with a full 6-year manufacturer’s warranty.
