Noctua unveiled two new super-slim A-series fans at Computex 2015. These include the all-white Slim 120 mm spinner, and the Slim 200 mm. The 120 mm Slim A-series is just 15 mm thick (compared to 25 mm standard); and features an all-white frame and impeller. It features an acoustic-optimized frame, with inner surface micro-structures that serve an anti-acoustic function; and vibration-dampening pads along its frame-mount, and included rubber bolts. An SS02 bearing gives the fan six-figure-hour MTBF. The 200 mm version features all those, plus a common Noctua-brown color scheme, and a 200 mm low-noise impeller.
