How to Adjust the Fan Speed on a Dell Laptop

All laptops have a fan installed inside to control the temperature and keep the computer from overheating. You can occasionally hear or feel the fan when it is running fast to cool down the computer. Sometimes, however, the fan doesn't run when the computer is too hot, or it is running too often. If you have problems with your fan's speed on a Dell laptop, you can easily adjust it using the Control Panel in Windows XP, Vista or 7.
