TROUBLESHOOTING
Insufficient cooling performance
Ensure the CPU block is mounted as described
■
in the instructions. Use only the mounting
equipment supplied with the unit.
Please operate the pump with 9 to 12 volts.
■
No voltage regulator below 9V should be used,
because this can damage the device.
Have you applied too much or too little thermal
■
paste? It is sufficient when it thinly covers the
back of the CPU.
After a drop in coolant is apparent, it is
■
advisable to top up the coolant level to
maintain optimum cooling performance. For
the correct way to top up the coolant, refer to
the installation instructions.
Please ensure that the airflow of the fans is
■
not restricted, to guarantee their maximum
performance.
Check that sufficient room is allocated to
■
the radiator, so it is able to draw in sufficient
cooling air and expel the warmed air.
Produces more noise
Check the coolant level and if necessary top
■
it up. The right way to do this is described in
the installation instructions. When the coolant
level is too low, it leads to more noise and can
damage the device.
The radiator must be mounted in a suitable
■
position in the case to prevent vibration and
turbulence in the airflow. Please also note any
advice given by the manufacturer of the case.

Make sure that no tubes or cables come into
■
contact with fans in the case. Bubbles of air
may have become trapped in the pump's
impeller during transportation. It may be
possible to free the impeller by repeated
switching on and/or loading cycles.
Painted surfaces of the radiator
The Silent Loop 2 water cooler uses an
■
aluminum radiator, which is originally silver in
color. The radiator is lightly tinted with black
paint, which from certain perspectives might
not be entirely opaque. This outer paint cover
does not affect the cooling performance in any
way.
The Silent Loop 2 water cooler is a cooling
■
unit intended for the cooling of processors
and made solely for that purpose. If you plan
to open up or modify its closed system we are
no longer able to guarantee its functionality
or cooling performance in any way. Please
only allow authorized service technicians to
undertake repairs. Opening the device besides
of the refillport voids the warranty.
Should you experience any other problems
■
with the water cooler, please get in touch
with our service department. You will find our
contact details at www.bequiet.com.
