The QL family from the American brand Corsair includes replaceable case fans designed for additional cooling of computer hardware. They can be useful in cases where the purchased case does not have its own cooling system or its efficiency leaves much to be desired. They can also be used to replace stock fans in tower coolers, video card cooling systems, and liquid cooling systems for CPUs.


From a technical point of view, QL series fans are largely the same as LL models. The maximum fan speed in most cases is in the range from 1800 to 2100 rpm. The minimum is most often 200 rpm. Torque is provided by a long-lasting hydrodynamic bearing.

Most fans are equipped with 8 individually addressable RGB LEDs, distributed between two separate light circuits. Lighting and fans are controlled through Corsair's iCUE software, allowing users to customize colors and effects to perfectly match the rest of the system.

As for the model range, traditionally for Corsair, almost all models are presented in two form factors (120 and 140 mm), as well as in two colors (black and white). For convenience, all turntables are sold individually or in sets consisting of two or three fans, as well as an optional controller for controlling the backlight.
