Lapinator. It's a pad you put under your laptop which absorbs and dissipates heat. If you have a laptop with fan/heat issues, this will be the best 25$ you have ever spent. I used to have a toshiba qosmio which started to constantly overheat and shut down after about a year of use, and this basically brought it back to life. If you sit with your laptop on your lap this this is awesome.
