Noctua NH-U14S CPU Air Cooler

The Noctua NH-U14S is the flagship 140mm model in Noctua's long-running NH-U single-tower series, a line that has accumulated more than 400 awards and editorial recommendations from international hardware publications since its introduction in 2005. Designed for builders who prioritise low noise alongside strong thermal performance in a form factor that remains compatible with high-end components, the NH-U14S strikes a deliberate balance between cooling capacity and physical restraint. At the heart of the cooler sits a six-heatpipe copper base connected to aluminium cooling fins, with all joints soldered and surfaces nickel-plated for corrosion resistance and long-term reliability. The tower stands 165 mm tall and measures just 52 mm deep (without fan), a purposefully slim profile that preserves full clearance for tall memory modules on LGA2011 and LGA2066 platforms. Including the fan and clips, total width reaches 150 mm, keeping the NH-U14S compatible with most SLI and CrossFire configurations. The included NF-A15 premium 140mm fan uses Noctua's SSO2 bearing and features Flow Acceleration Channels for refined aerodynamics. It spins up to 1,500 RPM at full speed, delivering up to 140.2 m³/h of airflow at a maximum acoustic output of 24.6 dB(A). Connecting the supplied Low-Noise Adaptor caps speed at 1,200 RPM, reducing airflow to 115.5 m³/h and noise to 19.2 dB(A) for near-silent operation. PWM support allows the motherboard to manage fan speed automatically, with a minimum of 300 RPM at the low end. The cooler also ships with fan clips and an additional set of anti-vibration pads so a second optional NF-A15 can be added in push/pull configuration, with the rear fan offsettable by 5 mm for improved acoustics in dual-fan mode. Mounting is handled by Noctua's SecuFirm2 system, widely regarded for ease of installation and consistent contact pressure. Out of the box it supports Intel LGA1200, LGA115x (LGA1150, LGA1151, LGA1155, LGA1156), LGA2011-0, LGA2011-3 (Square ILM), and LGA2066, plus AMD AM4 (kit included for coolers manufactured since 2019), AM3(+), AM2(+), FM1, and FM2(+). The product listing also references LGA1700 and AM5 socket support in the merged attributes; buyers should confirm current compatibility with Noctua's official socket list or contact support, as the source description does not explicitly enumerate those sockets. Noctua includes its NT-H1 thermal compound in the box — a professional-grade thermal interface material that has earned more than 100 editorial recommendations in its own right. The entire NH-U14S package carries a six-year manufacturer's warranty.
