Design Concept of Silent Spirit:
a) Fan Structural Design
The top-flow cooler “Silent Spirit” follows an
open frame structure concept whereby both design and dimensions
have been improved to eliminate humming and buzzing noises while
maintaining a compact overall size. The 92mm fan has been chosen
for silent operation and high airflow and comes with an
intelligent PWM control to allow users to set the fan speed in
their BIOS accordingly. In addition the anti-vibration fan
mounts are made of high quality rubber thus guaranteeing a long
life span even during high temperatures.
By precise calculations and proven by prototype tests during
the development stage, GELID's product developers concluded that
1. the optimal distance between the upper
holding rib and the Silent Spirit fan blade is around 5 to 5.5
mm to achieve minimum turbulent flow caused by the upper support
rib at minimum height.
2. the optimal distance between the side
support rib and the outer diameter of the Silent Spirit fan
blade is around 9 mm to achieve lowest turbulent flow caused by
the side support rib.
3. the location of two cable guards must be
especially designed to protect the fan impeller wedge by cables
and provide max space for incoming air with minimum resistance
from the fan holder structure.
4. thanks to the GELID intelligent PWM control
technology it is possible to keep silent operation at low CPU
temperature and to accelerate the fan speed when the CPU
temperature becomes higher.

b) Heatsink Structural Design
The cooler fan is installed on the heatsink at
an optimal position and angle to maximize the utilization of
cooling air to cool the heatsink.

3. Four high performance heatpipes soldered on
the copper base at full round shape, which can ensure heat
generated by single core, dual cores or quad cores CPUs can
evenly distribute to 4 heatpipes.

4. The nickel plated aluminum heatsink
connected with the heatpipe and copper base by soldering to
ensure heat transfer area of heatpipe can be fully utilized and
also prevent heat accumulation problem at low fan speed like
traditional tower heatsinks.
