Bitfenix 140x140x25mm case fan with White LED lighting, spinning at 700-1800rpm RPM for 47.7CFM of airflow at 20dBA noise. Uses a Fluid Dynamic Bearing for a longer, quieter service life than a cheaper sleeve-bearing fan, and mounts in any standard 120mm/140mm case or radiator fan position. A straightforward case-airflow or radiator fan upgrade, not a full cooler.
