I have a laptop that runs pretty hot - the fan is on all the time and it is physically hot to the touch. Do those cooling pads for laptops do a good job of cooling them down, or is it just hi-tech snake oil?
Cooling pad work but so does a pencil as Bostonian suggested. Anything that give the laptop room. A typical cooling pad has a built in fan as well so it forces the air flow, allowing the laptop to cool better/faster. However most of the overheating is caused by dust that blocks fans from circulating air. Blow your laptop out with compressed air and you should see a big difference.
