Why does my laptop sound like a jet engine?
Sharing is Caring

Laptops are designed to be portable and lightweight devices that can be used for a variety of purposes. However, it can be incredibly disruptive and even embarrassing when your laptop starts making a loud, high-pitched noise that sounds like a jet engine.

Why does my laptop sound like a jet engine? This issue is commonly referred to as “fan noise” and can be caused by many factors. In some cases, fan noise may indicate that your laptop is overheating and is struggling to dissipate heat. This can damage your laptop’s internal components, including the processor, graphics card, and hard drive. 

In other cases, fan noise may result from the laptop’s cooling system working harder than usual, either due to demanding software or simply because the laptop is getting older. 

Regardless of the cause, fan noise is not only a nuisance but can also indicate a serious underlying issue that needs to be addressed to keep your laptop functioning optimally. 

In this article, we will explore the common causes of fan noise and what you can do to resolve this issue.

Why does my laptop sound like a jet engine?

Fan noise in laptops can be caused by many factors, ranging from overheating to software demands. Regardless of the cause, this problem is not only a nuisance but also a sign of an underlying issue that needs to be addressed.

Laptop Overheating 

One of the most common causes of fan noise in laptops is overheating. When your laptop’s components, such as the processor, graphics card, and hard drive, generate too much heat, the cooling system will work harder to dissipate it. This can make the fan more noise, indicating that your laptop needs to cool down. Overheating can damage your laptop’s components if left unattended, leading to costly repairs.

Dust Accumulation

Laptops are designed with cooling systems that prevent overheating and prolong their lifespan. These cooling systems include fans and vents, which also serve as entry points for dust and other particles. Laptops on soft surfaces like beds or couches can also attract more dust than laptops on hard surfaces like desks. Also, dusty environments can contribute to dust accumulation in laptops.

Faulty Laptop Fan

A laptop fan is a small device that helps regulate the laptop’s temperature by dissipating heat. The fan operates by drawing air from the surrounding and passing it over the hot components of the laptop, thus keeping the temperature in check.

Faulty Laptop Fan

Causes of a Faulty Laptop Fan

  • Dust Build-Up
  • Worn Out Bearings
  • Software Issues
  • Hardware Issues

High-Performance Settings

Using your laptop for demanding gaming, video editing, or multitasking with multiple open applications requires more processing power. The increased demand for processing power results in increased heat generation, which can cause the laptop to overheat. To prevent this, the fan is used to dissipate the heat, thus keeping the laptop at a safe temperature. However, when the fan works harder, it can be loud and annoying, and in some cases, it can even reduce the fan’s life.

Software Issues

Software Issues

Several software issues can cause a high-speed fan noise. Some of the most common ones include:

  • Malware can cause high CPU usage, which in turn can cause a high-speed fan noise.
  • A misconfigured operating system can also cause high-speed fan noises.
  • Outdated drivers can also cause high-speed fan noises.

How do I stop my laptop from making a sound like a jet engine?

If your laptop is making excessive noise due to one of these factors, there are several steps you can take to try to fix the problem:

Clean the Air Vents

Your laptop relies on air vents to circulate air and regulate its temperature. If these vents become clogged with dust and other particles, your laptop may overheat, which can cause permanent damage to the internal components and reduce lifespan. Cleaning the air vents on your laptop is an easy and inexpensive way to prevent these issues and ensure that your laptop runs smoothly for years to come.

Check for Malware

Malware, short for malicious software, is any software designed to harm or damage a computer system. Malware can cause significant harm to your computer and steal sensitive information such as passwords, financial data, and other personal information. It can also slow down your computer, delete files, and render it completely inoperable. 

Check for Malware

There are several ways to check your laptop for malware. Here are some of the most effective methods:

  • Anti-Virus Software
  • Windows Defender
  • Online Scanners

Once you have identified the presence of malware on your laptop, it is essential to remove it as soon as possible. Here are some steps you can take to remove malware:

  • If you have anti-virus software installed on your laptop, it will most likely have a malware removal tool. Run a scan and follow the instructions to remove the malware.
  • Sometimes, the only way to remove malware from your laptop is by restoring it to its original state. This will erase all the data on your laptop, so back up your important files before proceeding with the restoration process.

Preventing malware infections is much easier than removing them. Here are some tips to protect your laptop from malware:

  • Keeping your operating system and software up-to-date can help prevent malware infections.
  • Avoid downloading files from unreliable websites.

Close Unneeded Programs

To keep your laptop running smoothly, it’s important to take steps to reduce the load and heat generation.

  • Close Unused Programs: The first and most obvious step to reducing the load on your laptop is to close any programs you’re not using. This frees up memory and processing power and reduces the amount of heat generated.
  • Disable Startup Programs: Many programs are set to start automatically when your laptop turns on, even if you don’t need them immediately. Disabling these programs can reduce your laptop’s load and increase its performance.
  • Uninstall Unused Programs: If you have installed programs you no longer use, uninstalling them is a good idea. This frees up storage space and reduces the load on your laptop.

Install Software Updates

Software updates are designed to improve your laptop’s performance, security, and functionality. They often fix bugs and security vulnerabilities that hackers could exploit. Updating your software regularly ensures that your system is protected against these threats and that you can take advantage of new features and improvements.

Upgrade your Thermal Paste

Thermal paste is a soft, heat-conductive material applied to a processor’s surface. It fills in the microscopic gaps between the processor and the heatsink, allowing for more efficient heat transfer. The paste also helps to maintain good contact between the processor and heatsink, even when there is slight bending or warping.

Over time, the thermal paste can dry out, crack, or become contaminated with dust and other debris, reducing its ability to transfer heat effectively. In extreme cases, a malfunctioning thermal paste can cause the processor to overheat, leading to system crashes and permanent damage to the processor.

Upgrading your thermal paste is a relatively straightforward process that can be done at home with the right tools and materials. Here’s a step-by-step guide to help you upgrade your thermal paste:

How to Upgrade Your Thermal Paste

  • Turn off your computer and unplug it from the power source.
  • Remove the screws securing the heatsink to the processor and gently lift it off.
  • Clean the surface of the processor and the heatsink with a soft, lint-free cloth and alcohol to remove any dirt or debris.
  • Apply a small amount of thermal paste to the centre of the processor, following the manufacturer’s instructions.
  • Reattach the heatsink to the processor and secure it with screws.
  • Turn your computer back on and monitor the temperature to ensure it operates within a safe range.

Replace the Fan

If the problem persists even after you have tried the above steps, you may need to replace the fan on your laptop. This is a complex task and should be performed by a professional.


If you want to find the answer to why my laptop sounds like a jet engine? Then it is clear that a laptop that sounds like a jet engine can signal an overheating problem, dust accumulation, malware, or software issues.
