Hello, I just set up an SFF PC with a Lian Li white PSU of 750W. Everything seems to be functioning properly, but I’m noticing a quiet buzzing from the power supply and the fan isn’t turning on despite using the 6900XT and 5900X models. This is unusual since those should activate the cooling fans. I’m worried about possibly getting a faulty PSU. Could anyone help explain what might have caused this issue? Your feedback would be really appreciated.

The unit will stop the fan once the load goes past 40%. Ensure it’s not just idle—avoid false alarms during gameplay. The humming noise is typical coil whine and doesn’t indicate a problem.
