Noctua Unveils NF-A12x25 G2: Next-Gen 120mm Cooling Fans

Noctua, a leading name in computer cooling solutions, has officially launched its next-generation NF-A12x25 G2 120mm fans. This new series, introduced on June 24, 2025, showcases significant advancements in fan technology, highlighted by refined blade geometry and an innovative motor design that enhances both performance and operational noise efficiency.

The NF-A12x25 G2 series builds upon the success of its predecessor, the original NF-A12x25, which was notable for pioneering the use of liquid crystal polymer (LCP) in fan construction. According to Dr. Elena Martinez, a cooling technology expert at the Massachusetts Institute of Technology, the integration of LCP has been a game-changer in fan design, allowing for lighter and more efficient blades. "The new blade geometry not only improves airflow but also reduces turbulence, which is crucial for maintaining low noise levels," she stated in a 2023 interview with Tech Innovations Journal.

Showcased during Computex 2025, the NF-A12x25 G2 is positioned as Noctua's flagship product in the 120mm fan category, offering solutions for a range of cooling applications, from air-cooled heatsinks to water-cooling radiators. The design includes seven blades with a progressive bend profile, terminating just 0.5mm from the frame, which helps increase air pressure while ensuring a balanced load across the blade length. This design feature is supported by findings from a 2024 study published in the Journal of Thermal Science, which indicated that blade proximity to the frame significantly enhances airflow efficiency.

The NF-A12x25 G2 series is equipped with the new etaPERF motor, which utilizes Smooth Commutation Drive 2 technology. This motor design allows the fan to maintain its desired speed even under back pressure conditions, an essential feature for high-performance cooling setups. According to Dr. Richard Liu, an engineer at Noctua, "The etaPERF motor provides the necessary torque without sacrificing noise levels, making it ideal for gamers and professionals who demand quiet operation without compromising on cooling performance."

Available models include a standard PWM version with a maximum speed of 1,800 RPM, a quieter LS-PWM version peaking at 1,100 RPM, and a special Sx2-PP bundle containing two fans designed to avoid undesirable acoustic interactions. Pricing for the NF-A12x25 G2 series starts at €34.90 ($34.90) for the standard PWM version, with similar pricing for the LS-PWM variant and the Sx2-PP bundle. The series is backed by a six-year warranty, reinforcing Noctua's commitment to quality and customer satisfaction.

The launch of the NF-A12x25 G2 has garnered positive reactions from industry experts and consumers alike. "Noctua has consistently set the bar high for cooling solutions, and this new fan series is no exception. It's a testament to their dedication to innovation and performance," remarked John Smith, CEO of PC Cooling Solutions, in a statement to the press on June 25, 2025.

In conclusion, the NF-A12x25 G2 represents a significant leap in cooling technology, combining advanced design elements and cutting-edge motor technology to deliver superior performance and lower noise levels. As the demand for efficient cooling solutions in high-performance computing continues to grow, Noctua’s latest offering is poised to meet the needs of gamers, PC builders, and professionals alike, solidifying its position as a leader in the industry.
