Why does my laptop sound like a jet engine?

Have you ever been sitting in a quiet room, using your laptop, and suddenly heard what sounded like a jet engine revving up? If so, you’re not alone. Many laptop users have experienced this phenomenon, and it can be both annoying and concerning. In this blog post, we’ll explore why laptops sound like jet engine and what you can do to fix the problem.

Why Does My Laptop Sound Like a Jet Engine?

There are a few reasons why your laptop might be making a loud, whirring noise that sounds like a jet engine. Here are some of the most common causes:


generate a lot of heat, and if they don’t have adequate cooling systems, that heat can build up and cause the processor to overheat. When this happens, the laptop’s fans will kick in at high speeds to try to cool down the processor, and that’s what causes the loud noise.

Dust buildup

Over time, dust and other particles can build up inside your laptop’s fans and other components, obstructing airflow and causing the fans to work harder than they should. This can also cause your laptop to overheat and sound like a jet engine.

Running intensive programs

If you’re running resource-intensive programs like video editing software or games, your laptop’s fans may need to work harder to keep the processor cool. This can cause the fans to make more noise than usual.

Age of Laptops

As laptops get older, their fans and other components can start to wear out, which can cause them to make more noise.

One disadvantage of older laptops is that they may not be able to keep up with the demands of modern software and applications. As technology advances, software programs become more complex and require more resources to run smoothly. This means that older laptops with less powerful hardware may struggle to run these programs and could become slow or unresponsive. Additionally, older laptops may not be compatible with newer operating systems, which could limit their usefulness and functionality. Finally, older laptops may be more prone to hardware failures or malfunctions, which could lead to costly repairs or the need for a replacement.

What Can You Do About It?

If your laptop sounds like a jet engine, there are a few things you can do to fix the problem,

Clean the fans

One of the most effective ways to reduce fan noise is to clean out any dust or debris that may be clogging them. To do this, you can use compressed air to blow out the fans or open up your laptop and clean them manually.

Use a cooling pad

If your laptop is overheating, a cooling pad can help to reduce the temperature and make your laptop quieter. These are small, portable devices that sit under your laptop and have built-in fans to help keep the laptop cool.

Adjust power settings

You can also adjust your laptop’s power settings to reduce the workload on the processor and make your laptop run quieter. For example, you can lower the screen brightness, turn off Wi-Fi and Bluetooth when you’re not using them, and close any programs you’re not actively using.

Upgrade your laptop

If your laptop is older and the fans and other components are starting to wear out, it might be time to upgrade to a newer model. Newer laptops often have more efficient cooling systems and are designed to run quieter than older models.


Insulating a laptop is not recommended as it can cause the device to overheat and damage the internal components. Laptops are designed to dissipate heat through the use of cooling systems such as fans, heat sinks, and thermal paste. Insulating a laptop can impede the proper functioning of these systems and lead to overheating, which can cause permanent damage to the device.

Additionally, insulating a laptop can also increase the risk of fire or electric shock. Laptops contain high-capacity lithium-ion batteries that can overheat and catch fire if they are not properly ventilated. Insulating a laptop can trap heat inside the device and increase the risk of battery failure, which can be dangerous.

In short, insulating a laptop is not a safe or effective way to improve its performance. If you are experiencing issues with your laptop overheating, it is best to address the underlying issue by cleaning the device’s cooling system, replacing damaged components, or adjusting the laptop’s power settings to reduce heat output.


If your laptop sounds like a jet engine, it’s usually a sign that something isn’t working as it should be. Whether it’s overheating, dust buildup, running intensive programs, or just old age, there are several things you can do to fix the problem.

By cleaning the fans, using a cooling pad, adjusting power settings, or upgrading to a newer laptop, you can make your laptop run quieter and more efficiently.
