i have not noticed until yesterday, but my wii is warm to the touch. I have it standing upright and the sides when you touch it you can feel the heat off the case. This is when the system is turned off. Orange light. I have not tested how hot the system gets with a game in it playing. I was at my friends today and his system was cold after playing about 2 hours. Should i be conserned about the system overheating. Should you feel air comming out of the back of the wii, i noticed the fan holes in the back and the bottom. but don feel any air comming out. I have had the system since it was released. Thanks.
