Following the success of our Spectre Fan Series, Spectre Pro ups the ante with an all-new design and enhanced performance. The high pressure and CFM design produces wicked cooling and is also perfect for watercooling setups. Its dual frame construction not only looks great, but also helps 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. With FDB technology for low noise and long life, multiple color options, and on-the-fly light switching, Spectre Pro is the new gold standard in performance case fans.Specification- Dimensions (mm): 230x200x30mm- Current (A): 0.41A 10%- Speed (RPM): 900 RPM 10%- Air Flow (CFM): 156.27 CFM 10%- Air Pressure (mmH2O): 1.81 mmH2O- Noise (dB-A): 25.6 dB(A)
