Enermax presents D.F. Storm: an industrial-high-speed fan with selectable speed up to 3,500 RPM. The Storm-flow fan blades are specifically designed to be used under extreme conditions. The sturdy design and the special shape of the fan blades will ensure a low-vibration operation, even at a rotating speed of up to 3,500 RPM. The extremely strong air flow and high static pressure of the D.F. Storm is ideal for radiators of CPU coolers in overclocked or high-end gaming systems. High quality and heat resistant components ensure 160,000 hours MTBF even at high operating temperatures.

The patented DFR™ technology allows the D. F. Pressure to remove automatically the dust from the fan blades. After starting the PC, the fan spins in reverse at full speed removing the dust. After that it will shift back to the normal operation mode.

The bearing shaft is fixed to the rotor. When you turn the fan on, a small magnet inside the bearing holds the shaft in position. The convex surface of the base reduces the frictional resistance and ensures a quiet and smooth fan rotation. The sleeve is made from a self-lubricating material and prevents the bearing from draining and corrosion. That way, Enermax guarantees an exceptionally long lifetime of 160,000 hours (MTBF). Another useful feature of the Twister fans is the “Click Mechanism”. By pressing the rear side of the blades, you can detach the rotor and clean it from dust. Put it back on the base and press it down until you hear a “click”.
