Exclusive self-cleaning solution
Super high 3,500 RPM Twister Bearing fan
Perfect for overclocking and gaming system
D.F. STORM – a high speed 3,500 RPM fan, equipped with
leading Twister Bearing technology. This industrial-grade fan
features the patented DFRTM technology, which allows the
fan to blow away dust to prolong its lifespan. D.F. STORM
also incorporates the patented APS PWM control for 3
different RPM ranges: 1500-2200/2800/3500, enabling
users to adjust the fan speed range according to their
system needs.
Features
Patented DFRTM technology instantly blows away the dust to prolong the lifespan
How it works
○
After 6 months
1. Patented DFR blows away the dust (full speed)
Within 10 sec.
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.
2. Shift back to normal spin
After 10 sec.
With DFR technology Without DFR technology
(more dust accumulates)
Super 3500 RPM

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 263.48m
(up to 11.13mm-H
2O) 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
