I've never experienced any heating issues with my wii. But I do sometimes just turn it off all the way just in case..
Same, It never seems to get "hot" maybe a little warm though. What are all the changes? Can anyone name them all? BTW I like the new sig Almo, I see you followed the tutorial perfectly!
Check the news portal 
wow, with all of the good new update features, they make the wii cooler too? WORSHIP NINTENDO!!!! lol
Maybe they were influenced by Microsoft? Better safe than sorry.
My Wii tends to get very hot, but it doesn't overheat. As long as this continues, it'll be fine by me.
Yes, it's does feel alot cooler now.
