No problems here, and I have been playing for a few hours.

My advice to u is not to get a usb fan that blows air into the wii. Im pretty sure all the wii stand fans blow air in. It will blow dust into the wii and decrease it's lifespan. Try to find a fan that attaches to the back and sucks air out of the wii.
