Easy fixes for a loud laptop fan

Although we all want a quiet PC, most of us have experienced loud fan noises that seem to come from nowhere. Most often, this is your fan doing what it’s supposed to (cooling your machine), so as well as dealing with this issue, you need to prevent it in the future. Read this article to discover techniques and methods for dealing with laptop fan noises.

  1. Remove dust

Dust is the most common cause of laptop noises. Dust damages your system in various ways including obstructing your laptops fan, which causes it to make loud noises.

Your laptop’s processor is essentially its brain; hence, we advise that you clean the processor’s cooler from time to time. To clean it; you need to open up your laptop using a screwdriver and use a blower to remove all dust particles. This should be done yearly.

If you are not a technically-minded person or don’t feel confident opening up your laptop, it’s best you send it to an engineer or ask a friend or family member to help you.

  1. Remove malware

Malware can contribute to loud fan noises as it can increase a laptop’s working temperature and cause it not to obey commands correctly. A good antivirus is an essential security and PC maintenance tool and your PC should never be without it.

If you install antivirus for the first time believing your PC may already be infected, you may be able to check this by checking the ‘Process’ tab of your machine’s Task Manager (which you can find by holding CTRL + Alt + Del). On the ‘Process’ tab of Task Manager, weird letters, disorganized arrangements, or strangely named processes are all signs of virus or malware presence.

  1. End processes

If you have many browser tabs and software running, or many processes running in the background, you might be overburdening your laptop’s processor and RAM and causing it to overheat. To end processes quickly, you can make use of Task Manager (which you can find by holding CTRL + Alt + Del). Simply launch the tool, right-click on a process, and hit ‘End task’ on the items you know you can quit.

  1. Use your laptop on the correct surface

As most manufacturers put laptop fans underneath the system, you can quickly dissipate excess heat simply by lifting your laptop for a few moments to let the air beneath it flow naturally. Then, ensure you only use your laptop on a hard, flat surface so airflow to and from the fan is not obstructed. 

  1. Use an additional cooler

If you’re gaming on your laptop or your job requires you to run many processes at once, you might wish to consider an additional cooler. Cooling your laptop will mean that its fan won’t have to work so hard, and noise will be reduced.

In conclusion

If you’ve noticed increased noise from your laptops fan, use CTRL + ALT + DEL to end some processes, lift it briefly, and then let it rest on a hard, flat surface. Make sure it’s cleaned internally and always ensure you’re running a reputable antivirus.
