The good news is that there are multiple solutions to the problem of a noisy laptop fan. A vital preventative precaution is regular cleaning of the vents to remove dust buildup.

The performance of your laptop can be improved by closing unused programs, controlling background processes, and installing the most recent versions of the operating system and drivers. If the issue persists, you may need to upgrade your gear or consult a specialist.

Here, we’ll examine each possible explanation for a noisy laptop fan in detail and offer helpful hints for resolving the issue.

Why Is My Brand-New Laptop Fan So Loud?

There are several potential explanations for why the fan on your brand-new laptop is so loud. Here are some probable explanations:

Dust and debris:

When there is a buildup of dust inside the laptop, the fan may have to work harder to maintain the desired temperature. If the laptop wasn’t thoroughly cleaned before shipping, even a brand-new one could have some dust inside.

High levels of computer processing:

When executing activities or programs requiring a significant amount of system resources, your laptop may produce more heat, which may cause the fan to spin more quickly and make more noise.

Inadequate levels of cooling:

The laptop’s cooling system wasn’t designed to withstand the heat created by the components all the time. Because of this, the fan trying to keep the system cool may make more noise as a result.

The fan that doesn’t work correctly:

There could be a problem with the actual fan itself in certain instances. It may be broken or misaligned, producing an abnormally high noise volume.

Taking place in the background:

Some of the programs or processes running in the background on your laptop are using up an excessive amount of system resources, causing the fan to work harder and make more noise.

BIOS settings:

Ensure that your laptop’s BIOS settings are set up correctly so that it can properly cool down. Incorrect settings may occasionally cause the fan to operate at a higher volume than is desirable.


When you overclock the components of your laptop, such as the CPU or the GPU, you may experience greater temperatures and an increase in the fan’s noise.

You can address the issue by attempting the steps that are listed below:

Make sure the laptop is clean:

You may use compressed air or a soft brush to clean the fan and the vents. This will remove any dust or debris, preventing air from flowing freely.

Keep an eye on and regulate the usage of the CPU:

Check Task Manager or similar programs to see if any processes take up excessive resources. You may need to exit programs that aren’t necessary or consider upgrading your hardware if your usage warrants it.

Make use of a heating pad:

Purchasing a cooling pad can help increase airflow around your laptop, minimizing the strain on the device’s internal fan.

Bringing drivers and the BIOS up to date:

Ensure that the drivers and the BIOS on your laptop are up to date, as laptop makers frequently provide updates to improve overall performance and fix issues related to fans.

Check for activities going on in the background:

To reduce the system’s resources, you should look for any extra apps running in the background and close them.

Final Views:

You should contact the manufacturer’s support or take the laptop to a repair center for additional assistance if the problem continues and the fan noise appears strange for a new laptop.

Why Is My Laptop Fan So Loud When Charging?

There are several potential causes for a laptop’s fan to increase in volume when charging. Some explanations could include the following:

Elevated Energy Use:

There is an increase in power consumption from the AC adapter when your laptop is charging. The internal components may overheat as a result of higher power usage.

The fan and other components of the laptop’s cooling system ramp up to full speed to disperse the extra heat and keep the device from overheating.

High Resource Consumption:

While it charges, your laptop could perform power-hungry tasks like software updates, virus scans, or taxing software. These actions may increase CPU (Central Processing Unit) consumption, increasing heat production.

So, the fan ramps up to keep the central processing unit at an appropriate temperature for continued operation.

Amount of Dust:

A laptop’s fan and heat sink are vulnerable to accumulating dust and debris over time. A decrease in cooling efficiency and an increase in fan noise result from this buildup. This problem may be solved by just cleaning the fan and vents.

Intensity Levels:

Some laptops’ power management systems optimize performance when plugged into an outlet. These configurations put performance ahead of noise suppression, resulting in higher fan speeds and more noticeable noise. If your laptop has a noise-reducing power setting, try it out.

Broken Air Conditioner or Fan:

A hardware problem could cause an abnormally loud fan noise during charging. The fan could break or malfunction, or the laptop’s cooling system could not work. If you think there’s a problem with the hardware, you should call a repairer to have a look.

Final Views:

It’s important to remember that the usual operation of a laptop fan is to increase in volume as the device is charged or under high strain.

However, it is advisable to consult a professional for diagnosis and repair if the noise is deafening, consistent, or accompanied by other strange symptoms such as overheating or unexpected shutdowns.

If your laptop is slow, here is the solution post for this: Why Is My Laptop So Slow?

Why Is My Gaming Laptop Fan So Loud?

Gaming laptop fans are loud for numerous reasons:

CPU/GPU overuse:

Running intensive games or apps on your laptop’s processor or graphics card generates heat. The laptop’s fan speeds up to prevent overheating, making more noise.

Dust and debris:

Dust and debris on fan blades and vents can block airflow. This buildup makes the fan work harder to cool components, generating noise. Cleaning the laptop’s cooling system regularly can help.

Low cooling:

Gaming laptops feature powerful hardware in a small space, which can limit cooling systems. If the laptop’s cooling design is poor, the fan may need to operate faster to maintain appropriate temperatures, making more noise.

Hardware issues:

Loud fans can indicate hardware issues. A noisy fan can result from a worn bearing or misalignment. If so, contact the manufacturer or a technician.

Performance settings:

Check your laptop’s power and performance. The high-performance mode may prioritize performance above noise reduction. The laptop’s power plan or fan settings may lessen noise.

Background processes:

Disable unneeded background processes. Gaming programs can use a lot of system resources, causing fan noise.

Final Views:

During strenuous tasks, fan noise is usual. However, if the noise is extreme or has increased without explanation, it’s best to examine and fix the problem. If you want the best gaming laptops, please check the Best 4K Gaming Laptops.
