So I think my wii is getting too hot. Started seeing some artifacting while playing Ghostbusters last night. Its gone today, but I don't want it coming back. Whats the best to keep my wii cool? The mod listed here: http://diy.sickmods.net/Tutorials/Wii/Prevent_Overheating/ (does the wii fan have different speed settings? I assume if it does, this circumvents this and has it on high? Also is the stock fan enough? even on high?) or should I just buy one of those external fans? Any recommendations on which one? The last time I took apart a wii was before I had one. Does the gpu have any sort of heat sink on it? Can I apply/reapply new thermal paste? Im a pretty good hardware modder, so have no problems adding a better fan internally if theres any good tutorials around.
