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.
Download the Speedfan utility from the page linked below and save the installation file to your desktop.
Double click on the installation file and follow the onscreen instructions to install the program to your computer.
Reboot your computer.
Open the "Start" menu, click on the "All Programs" list, and open the "Speedfan" program.
Click on the "Readings" tab and use the up and down arrow buttons to increase the speed of your fan to 100 per cent. If you can audibly hear your fan increasing in speed, your fan is working just fine.
