In Win today rolled out its Polaris Silent case fans. These 120 mm fans come in three key variants, the Polaris LED, which features a single-color LED illumination (and comes in sub-variants of red, blue, and green); the Polaris RGB, which comes with RGB multi-color LEDs; and the Polaris RGB Premium, which come with anodized aluminium frames, besides RGB LED lighting. The In Win Polaris is a 120 mm fan, with a circular frame. The mounts on the corners of the frame are rubberized to dampen vibration, and on the RGB-equipped variants, feature LED daisy-chaining headers, which let you connect up to three fans in a daisy-chain, and control them from a single fan that's plugged into a standard RGB header on your motherboard. The fan supports most modern RGB LED software standards, such as ASUS Aura Sync RGB, MSI Mystic Light, and GIGABYTE RGB Fusion.

As a fan, the Polaris series features high temperature-range PBT plastic making up the impellers, and polycarbonate frames for the Polaris LED and Polaris RGB variants; and aluminium making up the frames on the Polaris RGB Premium. Its motor features 35,000-hour rated sleeve bearing. The fans take in 4-pin PWM input, spinning between 500 to 1,280 RPM, pushing up to 43.31 CFM of air, with a noise output of up to 20.2 dBA. The fans will be sold in single-unit and two-unit packs.
