I have a Corsair 1Kw PSU and there is a noticeable “ticking” noise that is quite audible, sometimes louder than others. I have removed the PSU and spun the fan by hand and if I listen close then I can hear a faint ticking in the background. Obviously as the fan spins so much faster when being powered the noise gets louder. One weird thing is the noise level can fluctuate from very audible to just audible. I have inspected the top part of the fan to see if I could see anything touching the blades of the fan but can see nothing, so there has got to be something going on inside.
Has anyone else had an experience like this or does anyone have any advice as if anything can be done? The supply itself works fine and cost me more than I could afford so I can’t afford to replace it.
The PSU is about 6 months old and I don’t have any receipts or anything so I can’t take it back.
