I used to go outside and sit my laptop on the snow when it used to get too hot.

It... sort of worked. It cooled the laptop. Performance was discernibly better.

Until one day water (melted snow) got in and laptop stopped working. Totally serious, this happened.

Haha :) Before I retired it, I sometimes put my Asus Eee netbook in the fridge to cool it down. Somehow I managed to avoid getting ice inside the chassis. Pure luck probably :)
