What Is the Laptop’s Fan Used For?
A laptop fun is not just there for decorations. It is one of the major components of your laptop. Typically, it plays a vital role in its performance. But what is it used for? Let’s have a look.
The fan inside your laptop is responsible for cooling the internal components. When the laptop gets too hot, the fan will start to spin faster in an attempt to cool it down. This can cause a lot of noise, and in some cases, it can be so loud that it’s difficult to concentrate on anything else.
In addition to cooling the internal components, the loud laptop fan also helps to prevent the laptop from overheating. If the fan wasn’t there to cool the system down, the laptop would eventually overheat and shut down.
The fan also helps to protect the hardware inside your laptop. When the laptop gets too hot, it can damage the internal components. The fan prevents this from happening by cooling the system down.
Why Might My Laptop Be Running Loud?
There are a few reasons why your laptop fans might be running loudly, these include;
Dust and Dirt Buildup
If there is too much dust or dirt buildup on the fan blades, it will cause the fan to spin slower and make excessive fan noise. The best way to fix this issue is to clean the fan blades. You can do this by using a can of compressed air or a vacuum cleaner with the hose attachment. Be sure to avoid getting any liquid inside your laptop.
Problem with Fan Motor
If there is a problem with the fan motor, it will cause the fan to run loudly and make it difficult for you to concentrate. The only way to fix this issue is to replace the fan motor.
Your Laptop’s CPU is Overheating
As discussed, heat is the number one enemy of any electronic device. Your laptop’s CPU is the center of the heated battle. It’s where the heat is generated, so it makes sense that it would be the first thing to get fried. Therefore, you should keep an eye on your CPU temperature. If it’s consistently going above 80 degrees or going above 90 degrees while you’re doing everyday tasks, you should probably replace your laptop.
If you’ve taken good care of your laptop and recently changed the battery, there’s a chance your overheating is due to a bad CPU.
You Have a Loud Graphics Card
The graphics card is responsible for taking the data sent by the CPU and turning it into images that you can see on your screen. If your laptop is making a lot of noise, it’s because the graphics card is working harder than normal.
This usually happens when you’re running 3D games or other applications that require a lot of power. The louder your laptop’s fan is, the louder the roar of the graphics card. You should consider buying a new laptop if you think your current one is too loud.
You Have a Bad Case Fan
Case fans are meant to move air into and out of your laptop. If your case fan is making a lot of noise, then the air inside your laptop is also making a lot of noise. The good news is that you can replace case fans on your own. You’ll need to unscrew a few screws, pop open your laptop, and remove a few panels. After that, you can swap out your old fan for a new, quieter model.
The Fan Is Defective
In some cases, the fan itself might be defective. This can cause the fan to run loudly, even when there’s no dust or dirt inside the case. If you think your fan is defective, you should take it to a repair shop and have them look at it.
Defective Cooling System
If your laptop computer is making a lot of noise, but it’s not getting too hot, there’s a chance it’s not getting enough airflow. Take a look at your laptop’s vents. If they’re covered or have some kind of filter over them, it could prevent your laptop from getting enough air.
If your laptop is hot but not too hot, it means the cooling system isn’t working as effectively as it could be. The fan is trying its best to cool your laptop down, but they’re just isn’t enough air getting inside the laptop. This is usually a result of poor case ventilation.
How Can I Fix My Laptop’s Loud Fan Noise?
There are a few things you can do to try and fix your laptop’s loud fan;
Clean the Dust and Dirt from Inside the Case
One of the easiest ways to reduce noise from your laptop fan is to clean the dust and dirt from inside the case. You can do this by using a compressed air duster. Be sure to blow out all the vents and fan blades.
Replace the Battery
If your laptop is getting too hot, it might be because the battery is old and needs to be replaced. When a battery ages, it loses its ability to hold a charge. This can cause the CPU to work harder, which generates more heat. If you’re not sure whether or not your battery is bad, you can use a tool like Battery Eater to test it.
Turn Off Unnecessary Hardware
One of the best ways to reduce noise from your laptop fans is to turn off unnecessary hardware. You can do this by going into your computer’s BIOS and disabling some devices that aren’t being used.
Replace the Fan
In some cases, faulty fans themselves might be defective. This can cause the fan to run loudly, even when there’s no dust or dirt inside the case. If you think your fan is defective, you should take it to a repair shop and have them look at it.
It Could Be Time for a New Laptop
If none of this works, then it’s time for a new laptop. Newer laptops are designed with quieter fans. If your laptop is too old, or if the fan is just too noisy for you to live with, this could be your last option.
How do I know If My Laptop Needs A New Fan?
There are a few ways to tell if your laptop fans are broken or defective and need to be replaced:
- Suppose the fan speed is running loudly, even when there’s no dust or dirt inside the case.
- If your laptop is making a lot of noise, but it’s not getting too hot.
- When the cooling system isn’t working as effectively as it could be.
- Listen to the fun and evaluate the extent of the noise coming from your laptop.
- You can also check the air vents on the side of your laptop. If they’re covered with dust or dirt, there’s not enough airflow getting to the fan. This can cause your laptop to overheat and make a lot of noise.
If you’ve been hearing a lot of noise coming from your laptop, it might be time to clean the dust and dirt out to boost air circulation or replace the fan. It can also help if you turn off unnecessary hardware in BIOS settings and make sure that there are no filters covering any vents on your device. If none of these suggestions work, it may be time to buy a new laptop with quieter fans. We hope this answers the question: “Why is my laptop fan so loud?“
