How to Reduce the Fan Noise on a Compaq Evo N1020
The fan is essential to keeping the CPU cool. (blades of fan image by TEA from

The Compaq Evo N1020 laptop uses a fan to cool the CPU (central processing unit) and prevent overheating. However the fan can become quite loud. To fix this problem you should first clean the fan to see if this solves the problem. If this does not solve the problem then you can change your fan settings from within the BIOS (Basic Input/Output System) options menu. Making the fan spin more slowly will make it quieter, but less effective at cooling the laptop.

  1. 1

    Turn off your Compaq Evo laptop, and then unplug it and take out the battery.

  2. 2

    Place the laptop upside down---you will be able to see the fan vents. Compaq laptops are designed to be insulated against static shock, but, to be safe, you should touch a metal surface to discharge any static you may be carrying before going on.

  3. 3

    Unscrew the screws on the bottom of the laptop and lift the panel up and away to expose the inside of the device.

  4. 4

    Use a can of compressed air to blow any dust out from the inner workings of the laptop, especially the fan.

  5. 5

    Replace the panel on the bottom of your Compaq laptop, replace the battery, and turn it on. If you find that the fan is still too loud then you should try altering the fan settings.

  1. 1

    Restart your Compaq Evo laptop and hold down the F10 key to open the BIOS options menu. Here you can use the arrow keys to move around and the "Enter" key to select options.

  2. 2

    Select "H/W Monitor" and then select "Fan Settings." You can return to the previous menu by pressing the "Esc" key at any point if you go wrong.

  3. 3

    Make adjustments in small amounts and then start the laptop to check that it does not overheat. If not, then you can make more small adjustments. However, if your system becomes hot or unstable, you can go back and undo the most recent changes.

  4. 4

    Increase the "Fan Low Temperature" and "Fan High Temperature" settings to make the fan run less, and to run at its higher speed less often. Decrease the "Fan High Voltage" and "Fan Low Voltage" settings to decrease the fan voltage, which determines the fan speed.

  5. 5

    Return to the main menu by selecting "Save Settings and Exit" and then choose "Exit" to restart your laptop. The new fan settings will take effect immediately.

Tips and warnings

  • Slowing the speed of your cooling fan may cause the laptop to overheat, which can cause permanent damage to the system.
