Noctua NF-A20 HS-PWM chromax.black Noctua's NF-A20 has received numerous awards and recommendations from international hardware websites and magazines and is considered the reference for high-quality 200mm fans. The HS-PWM (High-Speed-PWM) version offers an attractive, all-black chromax.black design and an increased Speed of 1200rpm. Compared to the regular PWM version with 800rpm, it achieves over 40% higher flow rate and over 90% more static pressure. Award-winning NF-A20 design With dozens of recommendations and awards from the international trade press, the NF-A20 has become a reference in the field of high-quality 200mm fans. Its outstanding efficiency has already convinced tens of thousands of customers all over the world. 154mm, 110x180mm and 170mm hole spacing In order to ensure the widest possible compatibility with today's PC cases, the NF-A20 has three different hole spacings: While the 154x154mm and 110x180mm dimensions allow the replacement of most common 200mm fans, the 170x170mm dimension is used for many 230 and 250mm fans. which can also be replaced by the NF-A20.* Flow Acceleration Channels The impeller of the NF-A20 is equipped with so-called flow acceleration channels on the suction side. By accelerating the air flow in the critical outer regions of the fan blades, vortex shedding on the suction side is reduced, which leads to higher efficiency and lower turbulence-related noise emissions. AAO frame system Noctua's AAO (Advanced Acoustic Optimisation) frames feature integrated vibration buffers as well as a stepped inlet area (Stepped Inlet Design) and an inner surface microstructure, which enable even better performance/noise efficiency. Stepped Inlet Design The stepped inlet area of the Stepped Inlet Design creates more turbulence in the inlet. This facilitates the transition from laminar to turbulent flow, which adheres better to the frame (flow attachment) and thus increases the suction capacity of the fan, especially when the intake area is limited. Inner Surface Microstructures The microstructure in the inner area of the frame (Inner Surface Microstructures) creates a boundary layer through which the tips of the fan blades move. This reduces the flow separation from the suction side of the blade tips, resulting in a significant reduction in the rotational noise and an increase in pressure and airflow efficiency. has. SSO2 storage system The NF-A20 is equipped with the further optimized second generation of Noctua's proven SSO bearing system. With SSO2, the rear magnet is positioned closer to the fan axis for even better stabilization, resulting in further improved precision and durability. metal bearing shell In order to guarantee the greatest possible degree of manufacturing precision, minimal tolerances and excellent long-term stability, the fans in the chromax line use a CNC-milled brass bearing shell. PWM IC with SCD The fan supports fully automatic speed control via PWM and uses Noctua's specially designed NE-FD1 chip. This new PWM IC integrates Noctua's Smooth Commutation Drive (SCD) technology, which minimizes PWM switching noise and makes the fan even quieter at low speeds. 6-year manufacturer's warranty Noctua fans are known for their impeccable quality and outstanding durability. Like all Noctua fans, the NF-A20 has an MTTF specification of over 150,000 hours and comes with a full 6-year manufacturer's warranty.

If in doubt, please contact your case manufacturer.
Tootekood: NH-L12SX77GTIN: 9010018000504CPU Air Coolers
Der NH-L12Sx77 ist eine etwas höhere Variante des preisgekrönten NH-L12S und bietet eine verbesserte Kühlleistung sowie erweiterte Mainboard- und RAM-Kompatibilität. Mit sechs statt vier Heatpipes bietet er zusätzlichen thermischen Spielraum und wird weiterhin standardmäßig so konfiguriert, dass der Lüfter von unten nach oben durch die Kühlrippen bläst. Dies sorgt nicht nur für eine optimale Akustik in Gehäusen mit perforierten Seiten- oder Oberteilen direkt über dem Kühler, sondern hilft auch, die warme Luft aus dem System zu befördern. Durch die größere Bauhöhe konnte der Freiraum für hohe Mainboard-Kühlkörper oder RAM-Module deutlich vergrößert werden. Mit einer Höhe von 77 mm ist der NH-L12Sx77 dennoch kompakt genug, um in beliebte Small Form Factor (SFF/SFX) Gehäuse wie das Fractal Design Terra, Silverstone Milo ML12 oder Louqe Raw S1 zu passen. Ausgestattet mit dem bewährten SecuFirm2 Befestigungssystem und Noctuas preisgekrönter NT-H2 Wärmeleitpaste ist der NH-L12Sx77 die perfekte Wahl für SFF-Builds, die eine hohe Kühlleistung benötigen aber nicht ausreichend Platz für die größeren Kühlermodelle NH-C14S oder NH-D9L bieten.
