 How to Clean Computer Fans? Not all laptop computer repairs are created equal. The same computer repair can vary greatly from model to model.

This article will walk you through the steps of how to repair a computer to keep you cool. In some portable models of pc or laptops, it is very easy to remove and clean the CPU fan but in others, you will need a skilled technician to do the job. 

Cleaning a computer fan, such as the Acer Extensa, is very easy. To get started, you will need the following equipment.

  1. Small screwdriver
  2. Can of compressed air
  3. Tube of thermal paste

How to Clean Computer Fans?

Step 1. Start by removing the five screws on the bottom of the laptop. Gently pry the cover. You may hear a slight bouncing noise during removal, but do not worry that it should come out without a problem. 

Next, you need to remove the five screws that hold the heat sink and then the two screws that hold the CPU fan. Be careful there is a connector attached to the fan. You need to make sure you pull the plastic connector to remove it and do not pull on the cable.

Step 2. To clean your PC fans remove the heatsink from the laptop or computer and spray it in the compressed air to blow up dust and dirt that has accumulated to keep laptop dust free. 

Then remove the fan and do the same but be sure to hold the fan wheel in place when you blow it out into the air. You do not want the fan to rotate because the blades are delicate and they may be damaged.

Step 3. The final step in repairing this computer is to check the heat sink to see if the thermal adhesive, which was sitting on a small copper plate, has hardened and cracked. If the glue is still the consistency of toothpaste, there is no need to replace it. 

If however, it has hardened, take a credit card or some other thin piece of plastic that you can use to gently scrape the hard material both on the heat sink you removed and on the board inside the computer. 

Do not use a knife or any other metal object to ensure that you do not scratch the copper surface. When you are ready to apply a new ointment, first wipe the surfaces with a paper towel and then blow them out again with the compressed air. 

Put a little drop of dough on the heat sink and spread it evenly and place the part back on the computer.

Now you are ready to replace the fan with the two screws and do not forget to reconnect the connector. Do not start the screws, you do not want to distort the motherboard underneath by making the screws too tight. Even when you replace the back cover, rotating in a star pattern while tightening the five screws, it will help to get a uniform fit throughout the cover.
