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.80 PLUS & CYBENETICS CERTIFIEDThe Steel Legend series power supply unit offers options of 1200W, 1000W, 850W, 750W, and 650W, available in \"Steel Black\" and \"Steel White\" ideal for mainstream systems.
