The MULTIFAN series is designed to cool various AV components by accelerating cool air intake or
heat exhausting. Make sure the following requirements are met to ensure optimal cooling.
PRODUCT REQUIREMENTS
FULLY ENCLOSED CABINETS
USB cooling fans are ineffective in enclosed
cabinet applications. Air must be able to flow
in and out of the cabinet to be ventilated. Make
sure your cabinet is open in the front or has
ventilation holes.
REAR EXHAUST MODELS
Your cabinet’s ventilation holes must be located
at its rear to optimize the MULTIFAN S2. Hot air
blown out by the USB fan will flow out from the
cabinet’s rear openings.

SILICONE FEET
FEET DETACHMENT - FANS
The fan’s silicone feet can be detached to save
space. Easily unscrew the feet from the fan’s
frame. Put the screw back in after to secure the
fan guard.
FEET DETACHMENT - BLOWERS
The silicone feet is necessary to
prevent the blower from scratching your
electronics. It also reduces noise caused by
airflow turbulence from underneath the blower.
To remove, please pull on the bottom of the feet
carefully.

10
FEET REATTACHMENT - FANS
If you want to install the feet back, simply insert the silicone feet through the guard and onto the
fan’s screw hole. Turn until you feel the screw tightening but do not overextend or the screw will slip
through the rubber feet.
FEET REATTACHMENT - BLOWERS
If you are powering the register fan with an external outlet, run the power cord towards the groove
on the side of the register fan.

POWERING
USB PORT
Plug the fan’s USB connector into a
standard USB port. Please use a dedicated
USB port rated 500 mA or higher, the
standard on most electronics.
Please note that some electronics will have
active power for their USB ports even when the
electronic is powered off. This causes the fans
to run even if the electronic device is powered
off.
POWER OUTLET (SOLD SEPARATELY)
Check the LCD display to see if it is lit and
shows a number reading.

INLINE 3-SPEED CONTROLLER
The speed controller located on the cord
allows you to adjust the fan’s speed from off to
low, medium, and high. This enables you to set
the fan to optimal noise and airflow levels for
various environments.
Any fans that are daisy chained will also have
their speed changed. Please make sure that the
additional fans connected to the fan closest to the
power source have their speed set on high.

ADDING MORE UNITS
DAISY CHAINING FANS
Up to four fans can be daisy chained to share the same USB port. Up to six fans can be daisy
chained to share the same Boost Speed Adapter or Thermostat Fan Controller, both sold
separately. Dual fans such as MULTIFAN S7 count as two fans.

14
TOP EXHAUST - FANS
The USB cooling fans can be placed on top of
electronics that have vents on the top, such as
a DVR receiver to help draw out hot air. Unused
rubber feet can be detached to save space.
APPLICATIONS
TARGET COOLING - FANS
The USB fans can also stand upright to target
a specific electronic, component, or area you
wish to cool. They can also help circulate air
in narrow places such as inside a computer
desk or home theater cabinet by pushing hot
air away.
PC TOWER

15
APPLICATIONS
REAR EXHAUST - BLOWERS
The USB blowers are designed to help exhaust hot air from electronics housed in tight shelves
in which a fan may not have adequate space to blow upwards. They should be placed on top of
electronics that have ventilations holes on top such as receivers, amplifiers, and other audio video
equipment.
