Gelid Silent Spirit Quiet CPU Cooler

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 quiet operation and high airflow. It features an intelligent PWM control to allow users to control the fan speed in their BIOS accordingly. In addition the anti-vibration fan mounts are made of high quality rubber which guarantees a long lifespan even during high temperatures.

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.

The design of heatsink body contains two major elements a) unique fin architecture and b) heatsink orientation angle. The precisely calculated fins arrangement and architecture help the air from the fan to flow evenly and pass through all areas of the fins to maximize the air cooling performance. The unique heatsink angle helps to cool the components around the CPU but without generating a back flow of air. Also, the deliberate angle and the heatpipe arrangement can provide constant liquid circulation inside the heatsink at any orientation of the heatsink to ensure the stability of heat transfer.

Four high performance heatpipes soldered on the copper base on a full round shape, which can ensure heat generated by single core, dual core or quad core CPUs can be evenly distributed by the four heatpipes. The nickel plated aluminium heatsink connected with the heatpipe and copper base are soldered to ensure that the heat transfer of heatpipe can be fully utilised which prevents a heat accumulation problem at low fan speed as on traditional tower heatsinks.
