Noctua G2 140mm Premium Quality Quiet PC Connection NF-A14x25 LS-PWM, Fan, 4-Pin (Brown)

Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. Next generation 140x25mm design provides unprecedented quiet cooling performance in both high airflow and high static pressure applications: perfect as a PC case fan for CPU coolers and water cooling radiators. Cutting edge engineering (progressive bend impeller with winglets and centrifugal turbulators, flow acceleration channels, AAO frame) and construction (Sterrox LCP, ultra-tight tip clearance). Ultra quiet 4 pin low speed PWM version with a maximum speed of 800 rpm. Perfect for semi-passive setups (fan stops at 0% PWM) or ultra low noise applications requiring PWM control. Includes anti-vibration mounts, a 14cm anti-vibration gasket to tightly seal the radiator, fan screws, a low-noise adapter (LNA), an extension cable, and a Y-cable for running two PWM fans on the same header. Trusted Noctua quality with premium grade SSO2 bearings (MTTF ＞ 150,000h). UL and TÜV safety certified. Protected against reverse polarity, over-voltage and over-current (short circuit). Succeeding the award-winning NF-A14 and building on the innovations of the groundbreaking NF-A12x25, the NF-A14x25 G2 is Noctua's next-generation square-frame 140mm flagship. Manufactured from Sterrox LCP, it features a highly optimized progressive bend impeller with winglets, Flow Accelerator, and Acceleration Channels. Combined with a centrifugal turbulator hub and tip clearance of only 0.7mm, the NF-A14x25 G2 further improves on its predecessor's renowned quiet cooling performance. Like the NF-A14 and NF-A12x25, it is a true all-rounder that produces excellent results in all types of use, whether in low-impedance, airflow-oriented applications such as case cooling, or scenarios requiring high-impedance static pressure such as heatsinks and water-cooled radiators. For application-specific optimization, the NF-A14x25 G2 comes with a pre-installed NA-AVG2-LR anti-vibration gasket to create a tighter seal around your radiator. In addition, AAO (Advanced Acoustic Optimization) frame The NF-A14x25 G2 can be paired with the optional NA-IS1-14 inlet spacer to help achieve superior suction acoustics and flow rates in challenging intake configurations. The 4-pin LS-PWM version is a low-speed, PWM-enabled variant, ideal for semi-passive setups and ultra-low noise applications requiring near-silent acoustics and PWM-based speed control. The ultra-low loss etaPERF motor with Smooth Commutation Drive 2 technology combines unprecedented energy efficiency with exceptional running smoothness to please even the most noise-sensitive users. Topped off with Noctua's reference-class SSO2 bearings, an extensive accessory set, and a 6-year manufacturer's warranty, the NF-A14x25 G2 is a premium product. Its superior performance, comprehensive feature set, cutting-edge construction, and cutting-edge materials set a new standard in Noctua's portfolio, making it the elite choice for the most discerning demands.
