for $25 you can get either  a. a cool pad that has 2 fans that plug into usb that keeps it super cool but drains a little bit of battery, or  b. get a riser pad thing that allows more air to get under the bottom and takes advantage of the built in fan, and doen'st waste any battery, both work well, go with A if you plug it in a lot, go with B if your using it a lot wihout an ac plug
