4) Connect new fan.
5) Insert the new fan case into the enclosure until the cover locks. The fan
must be installed so that it intakes air (the labels on the fan must point
toward the inside of the cooling element) and the tab at the bottom side
of the fan case must be inserted into the designated slot.
Caution
When inserting the fan case ensure that the cable of the fan is placed be-
tween the cooling fins of the cooling element and does not extend into the
fan blades!
