Cooler Master MFX-B8NN-25NPK-R1 SickleFlow 80 - Black - 80mm Case Fan

Building upon the legacy of the SickleFlow 120 series, Cooler Master presents the next evolution with newly engineered design elements for superior performance.

The innovative SickleFlow 80 fan blades feature a refined design with larger surface area and enhanced curvature. This optimization results in improved airflow and increased air pressure. The structural integrity of the frame has been reinforced with additional ribbing, ensuring greater durability. Furthermore, enhanced dustproof and oil leakage prevention mechanisms contribute to a significantly extended lifespan.
