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.
