£9.99 buys a LOT of Duracells in Costco.
Not only will your Duracells eventually run out, but I'm pretty sure two rechargable batteries are less harmfull to environment than a bucket full.

If the Wii needed another cooling fan, Nintendo would have included one.
Yes, because console manufacturers always get the cooling systems correct the first time around (Microsoft proved that with the XBOX 360, right? right?).
More cooling is never a bad thing, as long as it's not too noisy.
Don't forget your coat.
