Well, its actually the coils.i remeber reading somewhere about capacitors squeeling, it may not blow but you will be able to claim on the warranty!
i suggest you go through the warranty
Well, its actually the coils.
What you are experiencing is called coil whine, at worst its just annoying. Power Supplies, Motherboards, Graphics cards, all can exhibit coil whine. RMAing the unit may get you one that doesnt whine, but coil whine will not affect life expectancy of the unit.
Try contacting OCZ themselves.They said I have to send it to neverlands its so far it would cost me half the supply price so I have contacted the place I brought it from. I cant belive this now its got so loud and high pitched that its hurting my ears so I am using ear plugs I have from work its unbelievable im not joking. Also it does it even when the pc is shut down..
