High static pressure cooling with LED illumination. Corsair Air Series LED high static pressure PC case fans combine efficient high pressure airflow with striking LED lighting. They're custom designed to deliver air directly to high-temperature components with less noise and turbulence than ordinary fans. The custom-molded blades are translucent and have a frosted texture, so the light from the four LEDs adds a dramatic effect. Designed for restricted spaces Air Series SP fan models are designed for use in restricted spaces. They're ideal for radiator and heatsink use, as well as drive bay intakes and other locations where you're mounting a fan directly adjacent to a heat source. For general purpose case ventilation where you'd like high airflow with minimal excess noise, check out our AF120 and AF140 LED fans.
