The Air Series SP140 LED White High Static Pressure 140mm Fan from Corsair is a PC case fan that combines efficient high pressure airflow with striking LED lighting. It is 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. Air Series SP fan is designed for use in restricted spaces. It is suitable 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.
