the fan duct down to the CPU.
Note: Lower the guide down as low as possible without touching the CPU cooler. This
is the most common way to cool a CPU that comes with a stock cooler.
Performance Mode
If you are a high performance user and you need extra cooling for your CPU.
1. Remove the side panel from the case.
2. Install a 92mm fan to the fan hood so that the air is blowing down to the CPU cooler.
3. Lower the lower air guide with fan down to the CPU cooler. This will bring extra fresh,
cool air to the CPU cooler and enhancing CPU cooling efficiency.
4. Connect the fan to the power supply or to the motherboard fan connector as instructed
by the manufacturer.
Note: We recommend lowering the air guide down so the separation distance between the
92mm fan and the CPU cooler to 20mm to get the best cooling effect.
Quiet Mode
If you are a quiet computing user and you prefer to install a passive CPU cooler (heat sink without
a fan) to get the most possible quiet operation.
1. Install a 92mm fan to the lower air guide as instructed above.
2. Lower the lower air guide down as low as possible without touching the passive heat sink.
Note: Please consult the manufacturer's recommendation for the minimum airflow to
work with the passive heat sink. You may be able to lower the fan speed beyond the man
ufacturer's recommendation, as the air guide will supply fresh cool air to the heat sink
directly. This will reduce the fan noise even further.
Maintaining the Washable Air Filter
From time to time it will be necessary to wash the installed air filter. Not washing the air filter will
result in higher system temperatures and possible stability problems. We recommend checking the
air filter at least once a month initially. The frequency will change depending on system usage
(users whose systems run 24/7 will likely have to check/wash more often than those who don't
use their systems every day) and on environmental conditions.
To remove the front door
In case you need to remove the double hinge door, open the door to 90º, and gently press the small
plastic tab on the upper hinge. Tilt the door away from the upper hinge pin, then lift the door off
the lower hinge pin. Set the door aside in a safe place.
To replace the door
Place the lower hinge slot over the lower hinge pin and press or rotate the top of the door in so
that the tab fully engages with the upper hinge pin.
