iCOOL Intelligent Fan Control Mode
iCOOL Mode ON: The power supply runs more efficiently. The fan stays off during low to medium loads, reducing noise and improving energy efficiency. The fan only activates when the load or temperature increases.
iCOOL Mode OFF: The fan runs continuously, regardless of load. This may increase noise slightly but provides consistent cooling and better performance under heavy loads.
