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
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

5. Four rubber fan mounts should be used to absorb
even the slightest vibrations from the running fan.

The cooler fan is installed on the heatsink at an optimal position
and angle to maximize the utilization of cooling air to cool the

The design of heatsink body contains two major elements a)
unique fin architecture and b) heatsink orientation angle.

The precise calculated fins arrangement and architecture can
help the air from the cooling fan evenly flow and pass through
all areas of the fins to maximize the air cooling performance.

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.

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.
