I was unplugging my hard drive so I could put in my computer after using my Wii. As I'm pulling it out it has a strange smell from the rear vent. The wii itself is also pretty warm after 15 minutes of use but I don't know if that's normal or not. Does the back of the wii have a fan? It looks like it does and if it does should I be able to see it spinning or feel the intake/outtake? I just don't want it to melt. Also the wii itself sits laying down on top of a plastic tv stand with plenty of room around it's vents.
