Replacing fans on an AudiaFLEX
This article explains how to replace the fans in an AudiaFLEX. The AudiaFLEX has either one or two fans, depending
on its configuration. The AudiaFLEX NC (No CobraNet) has a single fan, located on the right side of the chassis (when
viewed from the front). The AudiaFLEX CM (with CobraNet Module) has two fans: a chassis fan (same as the NC), as
well as a CobraNet fan that is internal to the unit.
The fans should be replaced if it makes excessive noise (especially grinding or groaning noises) or if it doesn't spin at all
when the unit is powered on. Note that AudiaFLEX fans are variable-speed and therefore they may not spin at all if the
temperature is low enough. However, they should always spin briefly right after the unit is powered on.
Replacement fans can be obtained from Biamp Systems, either as a warranty item or a spare part order. However, there
are several different fans available, depending on when the AudiaFLEX was manufactured. Please take note of the
serial number of the AudiaFLEX and call Biamp's Service department to ensure you receive the correct fan for
your AudiaFLEX.
