Question After disabling the eco mode my psu fan starts making an bzzz fan

[raudemik]

It's not an cheap PSU it's an evga 1000w gq gold 80+ and after i disable eco mode i dont know why it's making that strange bzzz from fan.
Should i worry? and put eco mode back on?

You should be concerned. It’s either the fan has a fault or something is touching the fan. If it’s an internal wire in the psu touching the fan that is a defect. If it’s something in the pc case pushing through the fan grill that needs to be sorted. If it’s the fan itself then the fan may soon fail.

i enable eco mode again an when this is on the sound dissapears even when the fan is on

Are you sure the sound is coming from the PSU. I would expect a desktop system fans to speed up a bit when not in eco mode but not the PSU, they are usually self contained.
