Keep Your Laptop Cool

Overheating laptops have gotten a lot of press over the last few years. The problem first gained popular attention around 2006, when reports of laptops actually catching fire started trickling in around the globe. The problem there was faulty batteries, and companies like Dell, Sony and Acer had to initiate major recalls.


The general issue of hot laptops is separate from those bad batteries, but laptop "explosions" certainly brought attention to the basic cause: Scorching heat is a bad trait for something that sits on your lap. People have actually gotten burned [source: BBC]. Short of that, hard drives are damaged by excessive heat.


But if the problem isn't a bad battery, what's making these laptops so hot?


You've probably noticed that all of your electronics get hot when they run for a while -- try putting your hand on the DVD player after you play a movie. Electronic components generate heat when they're working, and your laptop is no different.


In this article, we'll find out why laptops get so hot and see what you can do -- in terms of both maintenance and add-ons -- to keep yours cool. You don't even have to spend any money to do it.


There are two major reasons why laptops have more of an overheating problem than desktops. First, since laptops are smaller than desktops, those electronic components are crammed in there more tightly. Since they're closer together, and since the casing of a laptop is so narrow, there's not much room for the heat to dissipate.
