Automatic fan control
The built-in 120 millimeter fan has a smooth-running slide bearing, which ensures extremely smooth running during operation and a long service life. Seasonic's automatic Smart-and-Silent-Fan-Control-Technology (S2FC) ensures that the fan only starts when the load is 50 percent. This is particularly noticeable in the noise development and the maximum possible cooling performance, depending on how much the power supply is currently being used.
