Buzzing sound coming from PSU

Thread Starter 
I'm hearing a very feint buzzing sound coming from my PSU. I applied a bit of pressure to where the fan is to see if it was loose, but that wasn't it. I can only hear it when it's really quiet, like right now. I'm wondering what this might be and if I should take action to replace it right away. I don't want my PSU taking my whole system with it.

It's called coil whine. It isn't a really bad thing, but if it bothers you, RMA it.

As long as it's not a bad thing I think I can live with it. It doesn't do it a whole lot. Just every now and then I'll hear it.

Thanks ^^
