A laptop computer has a fan built into the case. It’s designed to circulate air and make sure that everything in the case does not get hot. This is the main reason why laptop fans are used and why they can be noisy when it is operating at its maximum capacity.

Check your Laptop Components

The reason for this is that the heat from the processor, the graphics card, the hard drive, and the other components are released during use. Since the temperature can reach up to a few hundred degrees Fahrenheit, there is a great amount of moisture that condenses on the parts that receive the maximum amount of heat.

If the components are not placed properly or if they are not cleaned properly, the condensation will cause a lot of noise.

The fan itself is an electronic device. In most cases, it works properly but it does occasionally run a little hot. If it happens more than once a day, then there’s a problem. It could be anything from dust or even a buildup of grease.


There are a couple of things that can cause the fan to overheat. Some computers have a very small amount of memory, which causes them to run a little hot. The fans that come with these computers are designed to cool off the memory. However, it can’t do its job properly without running a little hot as well. That’s when it’s time to check the cooling unit.

If you’re wondering why is my laptop fan so noisy, then it’s probably due to one of the three reasons. You can fix this problem by first getting rid of the bad parts of your computer and then making sure that your fans are running efficiently. However, this isn’t going to be easy for you unless you have a good grasp of computer science.

If you’re familiar with the working mechanism of a computer, then you’ll realize that a computer fan works by blowing air into a room. It’s like breathing for your computer, the better your air filter, the better your computer will run.

Fan Air Filter is Dirty

To avoid the problems caused by overheating and vibrations, proper cleaning should be done on the dust and other such devices. The cleaning process includes dusting the exterior of the machine and cleaning the components in order to prevent the build-up of dirt and other contaminants. There are also mechanical components such as blades, brushes, and fans that can cause excessive noise. when not properly maintained.

The first and most obvious bad part is that if you don’t have a good air filter, you’ll have lots of dirt on your machine. This will build up in the fan and start to make it noisy. A good air filter is one that can filter out 99.9% of the dust particles. If you do need to buy an air filter, you need to ensure that it is effective.

Cooling System

If the computer’s fan is overheating, that means something is wrong with the cooling system. Look at the cooling unit carefully and make sure that it’s not broken. You’ll need to check all the fans in the case as well.

Check the Power Supply

Your laptop fan may be too large for its electrical power supply. Some people get this problem when they use their computers with AC power instead of DC power.

You may find that your fan may not work when you plug it into an AC outlet. This is because the power is much lower in your laptop compared to the power that’s used by your computer for the AC cord.

If none of the other fans are working properly, then your computer may be overheating because it’s trying to cool the entire machine down. If this is the case, you’ll have to check the power and cooling unit and then the main power supply to make sure that everything is OK. 

Your Fan Needs Lubrication

Your laptop fan may be loud because you have run out of oil. Your laptop’s fan may run out of lubricant once in a while. This lubricant may get dirty or go bad and clog your fan up. When this happens, your laptop may not work anymore.

Broken Fan

If none of those things work, then your fan may be broken. This can be a lot easier to fix than an overheating fan. Most computer repair shops sell special fans that will be able to take care of your situation.

If you find that your laptop is overheating, you’ll want to figure out just why that is. The most likely reason is that you don’t have enough fans in the case to circulate the air correctly. or you’re installing a new cooling unit in an older model. Whatever the reason, the answer is, your fan is probably not cooling your computer properly.

The first thing you should do if you find that your fan is overheating is to turn on your laptop, let it heat up for a few minutes, and then look at the fans. If they’re overheating as well, then your fan may be broken. You can easily replace the fans yourself.

After you’ve checked the fans, you should also check the cooling unit. Check the speed controller switch to make sure it’s turned on. And operating properly. If it is, then it is possible that there’s no problem at all.

Loss of Efficiency

Your fan may have lost its efficiency. The more efficient the airflow gets, the more electricity it needs to operate. As its efficiency goes down, the amount of electricity that your laptop needs to run will also go down. As a result, you may notice that the fan that is on your laptop stops working and makes noise.

Call a Technician

If you find that your fan is broken, you may not need to call a technician. Your fan may be broken because the motor has broken or stopped working. In this case, you should simply pull it out and replace the broken parts.

Frequently Asked Questions

Why is my new laptop so loud?

There are times when a laptop fan noise can be caused by software related issues. Software issues can cause your temperature to run hot on your laptop. So in order for the laptop to cool down and avoid damage, it will increase the fan speed, sometimes causing fan noise.

How to Clean a Laptop Fan?

One thing that you need to be careful about when cleaning your laptop fan is to avoid using abrasives on your fan blades. Acrylic polish can easily chip away at the protective coating on your blades, which can lead to a short life span for your fan.

This can even be a safety hazard if the blades are not properly lubricated. You should only use compressed air when cleaning your laptop fan blades.

When cleaning your laptop fan, you will need to get a soft cloth, a small can of compressed air, and a towel. Before you begin, lay the towel on the bottom of the fan, so that the dust is on the top. Use the compressed air to suck up any dust that has built up on the fan’s blades.

You will also need to unplug the power supply, and then remove the laptop fan from its casing. Use the towel to wipe down the fan. Then, you will need to use the clean cloth to vacuum out all of the dust that is still left behind.


If your cooling unit is damaged, then you may have to replace the cooling fan and coolant. Make sure you read the manual for your laptop to determine how to properly care for the cooling unit.
