Laptops are meant to be portable and easy to carry, but when their fans suddenly start making loud noises and you don’t know how to fix them, your laptops are not very convenient to carry around!
One of the most annoying things about laptops is their noise. The fan inside the computer hard drive is loud and noisy. This is not very pleasant during lectures, meetings, or even relaxing in a coffee shop.
But why does it happen? What is causing my laptop fan to make such a loud noise? What can you do? This article will discuss why your laptop fan is so loud and help you fix the problem with fixes. continue reading!
1. Dirty/blocked fans
The most common cause of loud laptop fans is dirt or blockage. Over time, dust and other debris can build up and get between the cooling fan blades, making it harder for air to pass through them.
When this happens, the fan will have to work harder and spin faster to keep your device cool. This causes more friction between the fan blades and the frame, and generates more noise and heat than normal.
To prevent this from happening in the first place, keep your laptop clean by regularly dusting the inside or under the case, and blowing compressed air through the vents at least once a month if possible. Clean debris inside and outside the laptop fan assembly.
2. Blocked vents
If your laptop doesn’t get enough air through the vents, it will overheat and shut down automatically. This is a common problem with laptops as they are forced into unnatural positions so they drop or crush in their case.
To fix this, you can open the laptop and check for dust clogs in the vents on either side of the CPU fan (near where the screen hinge connects to the bottom of the laptop). Use a can of compressed air to blow out dust that’s been stuck there for months or years!
3. Faulty fan
If your laptop is hot, it may be due to a faulty fan. The fan should move air through the system to keep it cool and prevent overheating. When a fan fails, you can expect a lot of heat to build up inside the case, which will cause the CPU and other components to overheat.
The first sign of a failing fan is if your laptop is making strange noises, or if it’s completely silent when running on battery power. This can happen if something gets stuck between the fan blades, preventing it from spinning freely.
If this happens, take your laptop apart and remove any dust or dirt clogging the blades. If your laptop runs fine on AC power, but starts making weird noises when running on battery, it might be time for a new fan!
4. CPU overheating
If your laptop is running hot and loud, it could mean your CPU is overheating due to lack of cooling. When your computer overheats, it automatically shuts down to prevent damage to itself.
The solution here is to remove all the dust inside the laptop. Use compressed air or a vacuum cleaner to remove dust that has built up inside the computer. Many laptops have detachable keyboards that you can remove and use compressed air.
If that doesn’t fix the problem, your fan may have stopped working properly or has become clogged with dust, preventing it from spinning properly. Here, replacing the fan will solve the problem.
5. Insufficient ventilation
If your laptop lacks ventilation due to its design or location, it may overheat faster. For example, if you use your laptop in bed with it under a pillow or blanket, there won’t be enough airflow for cooling purposes. If there isn’t enough ventilation for proper cooling, consider moving it elsewhere (for example, on top of a desk) so that airflow can easily reach all system areas.
6. Outdated drivers
The drivers installed on your computer determine how well it operates, so if your drivers are outdated, this can cause problems with your laptop’s fan speed. For example, if you have an older version of Windows 10 installed on your computer, you may have an outdated driver installed. Make sure you have updated these drivers before trying other solutions to resolve fan speed issues.
7. Software bugs
Software errors, such as viruses and malware, can cause your laptop to overheat. Viruses and malware can drain your system resources and make your computer work harder than it should.
This will cause the fan to work harder, making it louder. If you have any doubts about the security of your computer, run a scan with an antivirus program to check for any problems. If found, you can remove it by following the instructions given by the program.
8. Outdated BIOS
If your laptop is more than two years old, it might be worth checking the BIOS to see if it needs an update. BIOS (Basic Input/Output System) is the software that runs when you turn on your computer and check all hardware components to make sure they are working properly.
The new version available for your system will notify you during the boot process with a message like “BIOS update required”. If you’ve been ignoring this message for months or even years, there’s a good chance you have a bug in your current BIOS that’s causing problems such as overheating and loud fans.
Malware is a virus that infects your computer by hiding in websites or email attachments. If you keep using the same password across different websites and services, this makes you more vulnerable to malware. If you suspect malware is causing problems with your laptop fan, scan your system for viruses and other unwanted programs with an antivirus program such as Avast Antivirus.
10. A large number of background programs occupy resources
If your laptop is slow or feels sluggish, it may be due to many background programs running on your computer. You may not even know these programs are running or using resources.
Some programs may use more help than others, resulting in an overall increase in the sound from the laptop cooling fan. The only way to fix this is to close all unnecessary programs so your system doesn’t get loaded with too much work.
11. Maybe other hardware than a fan to handle the added noise.
The increased noise of laptop cooling fans may be that they have other problems besides being dirty or clogged with dust and dirt particles. A faulty fan motor or not spinning at the proper speed can also cause this problem, and faulty bearings inside the fan itself can also cause it to spin too fast, causing it to vibrate more than usual when operating.
12. You have a lot of tabs open
The more tabs you have open, the more processor and memory resources your browser needs to load everything. This can cause your laptop to overheat and the fans to spin louder than usual. If you are using one tab, close all other tabs and see if that helps.
If the fan is making a lot of noise, there could be several reasons. The problem can be anything from a buildup of dirt and dust to a damaged laptop. It all depends on the laptop and how you use it.
