CPU chladič Noctua NH-C14S, 140 mm ventilátor, 12 V, 1500 RPM max, 163…

The Noctua NH-C14S is a top-flow CPU cooler that combines a deep fin stack with a single 140 mm NF-A14 PWM fan to deliver efficient heat dissipation with low noise. Designed as the successor to the award-winning NH-C14, the NH-C14S offers an adjustable layout that supports a low-profile 115 mm height mode for compact cases and a high-clearance mode that accommodates RAM modules up to 70 mm tall. The cooler uses Noctua's SecuFirm2™ multi-socket mounting system and ships with NT-H1 thermal compound.

Advantages

The C-type top-flow design provides effective airflow over RAM modules and motherboard socket areas while maintaining a lower profile than typical 140 mm tower coolers. The included NF-A14 fan features aerodynamic optimizations for quiet operation and supports PWM for automatic speed control; a Low-Noise Adaptor is also included to limit maximum speed. The cooler's offset layout improves clearance for the top PCIe slot on most µATX and ATX motherboards. SecuFirm2™ mounting and the proven NT-H1 thermal paste ensure reliable contact pressure and thermal transfer.

Suitable for (tasks / use cases)

• Quiet desktop systems and HTPC builds where low height is required
• Systems that need good RAM clearance (heat-spreaders up to 70 mm)
• Motherboards where top PCIe slot clearance is important (µATX and ATX)
• Environments prioritizing quiet cooling with efficient heat dissipation

Key specifications

• Fan diameter: 140 mm (NF-A14 PWM)
• Fan speed range: 300–1500 RPM (1200 RPM with Low-Noise Adaptor)
• Operating voltage: 12 V
• Dimensions (W × D × H): 140 × 163 × 115 mm (low-profile mode height)
• Weight: 0.82 kg
• Supported sockets: Intel LGA1851, LGA1700, LGA1200, LGA115x; AMD AM4, AM5

How to use

Choose the mounting orientation based on clearance needs: install the NF-A14 fan underneath the fin stack for low-profile mode (115 mm total height) or on top of the fin stack for high-clearance mode to allow up to 70 mm RAM height. Install the cooler using the supplied SecuFirm2™ mounting hardware following the included instructions for your CPU socket. Apply a thin, even layer of the supplied NT-H1 thermal compound to the CPU heatspreader before seating the cooler to ensure optimal thermal contact.

Recommendations

For quieter operation, enable PWM fan control in the motherboard BIOS/UEFI and use the supplied Low-Noise Adaptor to cap maximum fan speed at 1200 RPM. Verify clearance around the top PCIe slot and RAM modules before final installation, and periodically check mounting screws for secure contact.
