‧ Exclusive self-cleaning solution
‧ Super high 3,500 RPM Twister Bearing fan
‧ Perfect for overclocking and gaming system

Patented DFR™ technology instantly blows away the dust to prolong the lifespan


3,500 RPM for industrial application

Designed for extreme applications and conditions (hardcore gaming rigs, servers, industrial systems, supercomputing, etc). The maximum 3,500 RPM is set for extraordinary high cooling performance.

* Please use the 4-Pin adaptor included to power the fan directly from the power supply unit when the Turbo Mode (1500-3500RPM) is selected.


Storm-Flow blades generate +30% airflow and enhance airflow momentum

Innovative Storm-Flow blade design comes with sophisticated inclination inlet & outlet angles, which generates up to 30% more airflow than normal blades. The extremely strong airflow (up to 263.48m³/h) and high static pressure (up to 11.13mm-H2O) make D.F. STORM ideal for extreme applications


Patented APS (Adjustable Peak Speed) with control switch provides 3 peak RPM options

With LED indicator and the APS switch, users can easily indentify the current RPM setting

APS PWM Control
*Performance:1500~2200 RPM (Blue indicator)
*Overclocking:1500~2800 RPM (Green indicator)
*Turbo: 1500~3500 RPM (Red indicator)


PWM speed control keeps your system cool and silent at all times


Patented Twister Bearing technology for long lifetime and low noise

Smooth and persistently reliable operation thanks to the patented Twister Bearing technology. Along with more industrial grade components (double-layer PCB, larger magnet, etc.) to ensure 160,000 hours MTBF even at high operating temperatures.

Detachable blade for easy cleaning


Shockproof rubber on screw minimizes vibration during operation
