Heh.
How to (liquid-)cool a laptop:
0) Open freezer door
1) Place laptop inside
2) Wait 24 hrs, remove from freezer, thaw
3) Buy a new laptop as a result of internal water damage to old laptop.
i was thinking of more along the lines of just take your hose, and turn it on high and fire water at it, then sit in your freezer. hahahahaha.
on a more serious note, what i would suggest is do regular clean outs of it with the compressed air. clean it out at the end of every week. ya know, play on it for a week and on Friday or Saturday, give it a nice cleaning.
