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.

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.
