Dissipador de CPU Noctua NH-U12S, ventoinha de 120 mm, 1500 rpm, 93,4 m³/h de fluxo de ar, 22,4 dB, aço inoxidável, 158×125×71 mm

The Noctua NH-U12S is a 120mm single-tower CPU cooler from Noctua's U-series, featuring a slim 45mm fin stack and the NF-F12 120mm Focused Flow™ PWM fan. The design ensures full compatibility with tall RAM modules and common motherboard layouts while providing quiet cooling performance. The package includes the SecuFirm2™ multi-socket mounting system, Noctua NT-H1 thermal compound and a 6-year manufacturer warranty.

Advantages

The NH-U12S offers 100% RAM compatibility thanks to its 45mm fin depth, a compact 158mm height that fits most mid- and high-end tower cases, and a 125mm total width that keeps it clear of top PCIe slots on standard ATX and Micro-ATX boards. The NF-F12 fan delivers high static pressure and low noise, with PWM support for automatic speed control and an included Low-Noise Adaptor to reduce peak RPM. The cooler also supports an optional second NF-F12 in a push/pull configuration with supplied fan clips and anti-vibration pads. The SecuFirm2™ mounting provides secure multi-socket compatibility and easy installation, and the NT-H1 thermal compound ensures reliable thermal transfer.

Key specifications

• Form factor: 120mm single-tower cooler
• Fin depth: 45 mm (slim design)
• Height: 158 mm
• Width (including fan and clips): 125 mm
• Included fan: NF-F12 120mm Focused Flow™ (PWM)

• Thermal compound: NT-H1 included
• Warranty: 6 years manufacturer warranty

How to use

Install the SecuFirm2™ mounting brackets onto the motherboard following the supplied instructions for the target CPU socket. Apply a small, pea-sized amount of the included NT-H1 thermal compound to the CPU heatspreader, position the NH-U12S heatsink on top and secure it with the mounting hardware to ensure even contact pressure. Connect the NF-F12 PWM fan to the CPU fan header for automatic speed control and optionally fit the Low-Noise Adaptor for reduced maximum RPM. If a push/pull configuration is desired, attach the second NF-F12 using the supplied fan clips and anti-vibration pads, offsetting the rear fan by 5 mm if needed for better acoustics.

Recommendations

For best results, verify case clearance for the 158 mm cooler height and the 125 mm width relative to the top PCIe slot on your motherboard. Ensure the CPU fan header supports PWM control for automatic fan speed management and keep the NT-H1 compound store instructions in case of future reinstallation.
