I am a person that does not like to open my wii up for any reason, but it is the better way to clean out the dust. When using compressed air to blast it through, I would do it though the cooling slots. that is where it is sucking in air anyways and it will come out where the fan is.
However do keep in mind that you have to be careful when using compressed air to clean your wii. Make sure you hold the can right side up. Also make sure your wii is unpluged when doing this.
Some people feel that compressed air does not help and just stirs up the dust, it didnt hurt my system at all, but it is your call
Also, I joined up for season 2 of the Mario Kart tournament. I look forward to racing you aging
