Noctua has announced the chromax.black edition of its flagship NF-A12x25 G2 120mm fan. The new all-black variants maintain the technical specifications of the regular G2 model, including the Progressive Bend impeller and Sterrox liquid-crystal polymer construction. The fans are available immediately in single units and speed-offset dual-packs.

The NF-A12x25 G2 features a 0.5mm tip clearance and a Centrifugal Turbulator hub to improve performance-to-noise efficiency. It features Noctua's etaPERF motor with SupraTorque technology, providing additional torque headroom for high-impedance applications, such as water-cooling radiators. The chromax.black version is compatible with Noctua's optional coloured anti-vibration pads for aesthetic customisation.

For multi-fan configurations, Noctua offers the Sx2-PP set, which includes two fans with a ±50rpm speed offset. This design is intended to prevent acoustic interference and harmonic phenomena, such as periodic humming, when fans are used in push-pull or side-by-side on 240mm or 360mm radiators.

The fans feature the SSO2 bearing system and carry an MTTF rating exceeding 150,000 hours. Noctua backs the series with a 6-year manufacturer's warranty. The NF-A12x25 G2 PWM chromax.black is priced at €34.90/$34.90 for the single fan, while the Sx2-PP dual-pack is available for €64.90/$64.90.

Thermaltake has expanded its ecosystem with the launch of the CT120 EX Infinity, a more streamlined alternative to the Swafan EX Infinity series that recently hit the market. While the CT series has traditionally served as the brand's entry-level offering, these new models elevate the aesthetic by incorporating an infinity mirror lighting system.

As seen by the images shared by Thermaltake (via Cowcotland), this design features a fixed white inner ring on the fan hub paired with a fully customisable ARGB outer ring. This creates a layered visual effect that is far more refined than previous standard CT models. The CT120 EX Infinity 3-packs are available in black and white versions.

Performance-wise, Thermaltake has pushed the CT120 EX Infinity well beyond the typical “case fan” expectations. The fans operate at a PWM range of 500 to 2000 RPM, generating a robust 68.20 CFM of airflow and a static pressure of 3.05mmH₂O. Despite these figures, the hydraulic bearing design and non-detachable anti-vibration rubber pads help keep noise levels at approximately 28.5 dBA, ensuring the fans remain relatively quiet even at full throttle. To further improve cooling efficiency, Thermaltake has increased the fan frame thickness to 28mm, enabling better air pressure and airflow than conventional 25mm models thanks to the thicker fan blades.

These new fans also feature MagForce 2.0 Quick Connect, a magnetic daisy-chaining system that uses Pogo pins twice the size of those on original Swafan EX models. Thanks to this system, the risk of misalignment and the mess of multiple cables is reduced. For builders who still require individual placements, Thermaltake includes three separate magnetic cables in the 3-fan pack, allowing each unit to function independently with standard PWM and ARGB connections. Additionally, the fans feature a “hidden screw” design with small plastic covers that snap over the mounting screws.

KitGuru says: Pricing isn't known yet, but considering they're part of the CT series, we expect it to be relatively affordable, even considering its feature set.
