D.F. Storm 12cm
High-Speed Fan

Product Introduction

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.

Dust Free Rotation™ Technology

  • DFR™ (Dust Free Rotation) technology
    The patented DFR ™ technology helps to increase the product lifetime by reducing dust accumulation and therefore incresing the cooling performance.
    The fan
    reverse spins after starting to remove accumulated dust from the fan blades.
    After 10 seconds it returns to normal operation.

Speed Controls

  • Adjustable Peak Speed (APS)
    Multi-purpose fan for easy customisation according to the system requirements. With a small switch on the side, the end user can choose three different RPM ranges: Performance Mode / Overclocking Mode / Turbo Mode. The LED indicates the chosen mode.
  • PWM Speed Control
    Flexible fan speed control via mainboard pulse width modulation (PWM) within the selected RPM range Modus (1,500~2,200 RPM / 1,500~2,800 / 1,500~3,500).

Powerful Cooling

  • The 2nd Generation of the Patented Twister Bearing
    Smooth and persistently silent operation due to the patented Twister Bearing Technology. The second generation of the bearing guarantees up to 160,000 hours MTBF.
  • Storm-Flow Blade Design
    Innovative Storm-Flow blade design comes with sophisticated inclination inlet & outlet angles, which generates up to 30% more airflow than normal blades.

Easy Maintenance

  • Click Mechanism
    Detachable blades for further easy cleaning from dust.
  • Effective vibration reduction
    Four isolator mounts reduce vibrations and make the fan installation easier.
  • Warranty
    2 years

Included in Delivery

  • 12cm D.F. Storm fan
  • 4 shock-proof isolator-mounts
  • 4 screws
  • 4-Pin to 4-pin molex adapter

Dust Free Rotation™ Technology


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 2nd Generation of the Patented Twister Bearing Technology

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”.


Adjustable Peak Speed™ Function

Easy fan speed customisation according to the system requirements. With a small switch on the side, the end user can choose three different RPM ranges: Performance Mode / Overclocking Mode / Turbo Mode.

Performance Mode Oveclocking Mode Turbo Mode
1,500 ~ 2,200 RPM

1,500 ~ 3,500 RPM
