How to Test the Fan on My Laptop

The laptop fan is an integral part of the system, responsible for keeping the internals of your laptop cool under pressure. Without the fan, your computer would overheat in mere minutes, ruining an investment of several hundred (or thousand) dollars. Testing your computer fan requires the use of the free Speedfan software utility, a one-of-a-kind utility designed to work with a variety of computer models.
