Corsair Air ML140 Pro Computer case Fan 14 cm Black, Transparent Corsair is expanding its range of fans with the introduction of the ML series, an acronym that reveals the technological nature of the new series of magnetic levitation fans. The Corsair ML fans provide quiet operation and excellent performance, thanks to magnetic levitation of the rotor and the owner of the design of the fan blades. The innovative design is able to considerably increase both the static pressure and a flow of air, thanks to the very low friction of the magnetic levitation system. Moreover, thanks to the 4-pin PWM connector is possible to adjust timely the fan rotation speed so as to manage the performance / noise ratio appropriately. The PRO version includes in the package a set of silicone nose pads, interchangeable with optional sets of various colors (red, white and blue) that have the dual function to cancel the vibrations produced by the fan itself and beautify the fan, matching the color of nose pads to that of your system! Finally, the LED version is equipped with 4 high-brightness LED inserted in the rotor of the fan, guaranteeing maximum brightness and uniform lighting along the translucent material blades.
