Corsair AF and AR fans are very similar both in appearance and in terms of technical characteristics. The difference is that AR models are one step lower in the brand hierarchy, most of them lack anti-vibration cushions, and the average warranty period has been reduced from five years to two. AF fans have 9 small blades so the gaps between them are larger, unlike AR fans which have 7 large blades and smaller gaps. AR fans are presented on sale mainly in standard 120 mm versions, AF coolers in most cases can be purchased in both 120 and 140 mm.


Otherwise, these are classic case fans with durable hydrodynamic bearings, PWM control and a maximum rotation speed of up to 2200 rpm. A relatively quiet and durable hydrodynamic bearing is usually used as the basis. For convenience, the cooling system can be purchased individually or as a set of three fans. Given the growing popularity of snow-white cases and components, Corsair is trying to release all new products in both black and white.

As is typical for Corsair, the fans are equipped with dual light loops with addressable RGB LEDs, allowing for complex and colorful visual effects. Lighting and fans are controlled through Corsair's iCUE software, allowing users to customize shades and lighting effects to match the rest of the system. Due to their high cost, iCUE LL fans are primarily aimed at use in showroom/modding PCs and high-performance gaming systems equipped with components with high heat generation.
