Laptops are more powerful than ever - and more processing power means more heat to be dissipated.
Unfortunately, due to their small size, laptops tend to be fitted with small cooling fans. If you want to keep your laptop cool - which will make it run faster and last longer - you should use a laptop cooling pad.
There are two types - passive, with no fans and active, with one or more fans.
If you have a powerful laptop, or if your laptop is on for a lot of the time, then a passive laptop cooling pad is probably the best choice for you.
