SilverStone today introduced the Air Slimmer 140, a slimline 140 mm case fan. The fan comes with a thickness of just 15.5 mm, compared to the 25 mm that's typical of 140 mm fans. This should come in handy if you choose a thicker radiator, or are building an SFF machine. The fan features a copper fluid dynamic bearing, although the company didn't specify endurance numbers. The 9-blade impeller features what SilverStone brands as Shark Force patterns, which improve noise characteristics.

The fan takes in 4-pin PWM input, and supports ultra-low speeds. It turns at speeds ranging between 0 and 1,700 RPM, with a maximum airflow of 82 CFM, at 2 mm H₂O static pressure, and 33 dBA maximum noise. It includes cables for daisy-chaining. There are two key variants of the fan, the base variant comes with a black impeller and lacks any lighting, and then there's the Air Slimmer 140 ARGB, which has a white impeller and 9 LEDs studded in the hub. It takes in 3-pin ARGB input for the lighting. The all-black version is priced at $19.99, and the ARGB version at $24.99.
