recommended for heavy graphics processing, extreme gaming or overclocking.
• High Cooling Mode (Yellow)
When the system is not running at its maximum load but needs extra cooling, the fan runs
at 80 % of its maximum speed. This setting is recommended for intensive or prolonged
usage, or when multiple graphics cards are installed.
• Medium Cooling Mode (Green)
The fan speed is set at around 65 % as the computer turns on and it will gradually
increase as the system load exceeds 80 % of its maximum possible load. This setting is
ideal for everyday, normal operation.
• Low Cooling Mode (Blue) (Default setting for new power supplies)
Light cooling is provided up to about 60 % of the maximum possible load. This setting is
most commonly used for an average computer build and light usage.
• Silent Mode (White)
This is the most ideal setting for average office usage and for the most silent operation.
The fan control optimizes fan speed according to the following three stages:
I. Zero fan speed under 40 % load
II. Medium cooling between 40 % and 80 % load
III. Intensive cooling between 80 % and 100 % load
