    Hey all,

    For whatever reason I decided to pick up my power brick to see how hot it got while charging. Needless to say, it was extremely hot. This is to be expected though, and is not the cause of this thread. My question is, and dont ask me why I did this lol. But has anyone else heard noises, similar to a fan, coming from their power brick? I put mine next to my ear, for whatever reason, and this is a loud fan like buzzing noise, particularly on one side of the adaptor. Any ideas why? I think its just the energy moving around in there, but maybe I'm missing something?

    They do make some noise, as all transformers do. Nothing to be concerned about there.
