BitFenix Spectre Pro 230mm Black Tinted Green LED Fan

Spectre Pro LED ups the ante with an all-new design and enhanced performance. The high pressure and CFM design and dual frame construction not only look great, but also help to dampen vibrations that cause unnecessary noise. Reinforced fan blades prevent warping at high RPM levels, while focused airflow ensures cool air can reach all of your installed components. Features FDB technology for low noise and long life, multiple color options, and on-the-fly light switching.
