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 micro-ATX and ATX motherboards. Topped off with the trusted, pro-grade SecuFirm2 multi-socket mounting system, Noctua\'s proven NT-H1 thermal compound and full six years manufacturer\'s warranty, the NH-C14S is a premium quality top-flow solution for the highest demands.Based on the award-winning NH-C14Having 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 designThe 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 ModeRun 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 ModeRun 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 clearanceCompared 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 micro-ATX and ATX motherboards when the bendings of the heatpipes face the PCIe slots or the I/O panel.NF-A14 140mm premium fanFeaturing 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 AdaptorThe 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 1200 RPM using the supplied Low-Noise Adaptor for even quieter operation.Specification:Max TDP: AllInstallation Method: Intel and AMD - backplate, requires motherboard removalHeight (without fan): 115 mmWidth (without fan): 140 mmDepth (without fan):163 mmHeight (with fan): 115/142 mmWidth (with fan): 140 mmDepth (with fan): 163 mmWeight (without fan): 820 gWeight (with fan(s)): 1015gMaterial: Copper (base and heat-pipes), aluminium (cooling fins), soldered joints & nickel platingFan compatibility: 140x140x25mm (with square frame)Fan specifications: Model: Noctua NF-A14 PWMBearing: SSO2-BearingRotational Speed (+/- 10%): 1500 RPMRotational Speed with L.N.A.
