Why Does My Laptop Sound Like A Jet Engine

Why Does My Laptop Sound Like A Jet Engine

Why does my laptop sound like a jet engine? Do you ever wonder or question yourself? If you are experiencing this issue, you should inspect your laptop’s cooling fan. While other factors may play, the cooling fan remains at the top of the list of causes for such technical troubles.


That’s the thing about laptops: in exchange for portability and the flexibility to work (and play) from anywhere, you get a computer prone to overheating. There’s not enough area for air to move freely, and there aren’t enough fans to make it so, unlike a full-fledged desktop PC. And, with all of those components, like the hard drive and batteries, crammed together, heat may easily build up within your laptop, even during normal use.

Why does my laptop sound like a jet engine?

The sound you are hearing is typically caused by a fan belt slipping. When the fan belt slips, it rubs against the pulleys, creating a distinctive jet engine sound. To prevent this from happening, check to see if the fan is turning by looking for the light on the front of the computer case. If the fan is not turning, the belt has likely slipped. To fix the issue, you will need to replace the fan belt.

Other factors

There could be some other factors at work. On the other hand, a problem like this is usually caused by a cooling fan. It usually means dirt has gathered on or around the cooling fan when this happens. Let’s take a closer look at some of the most prevalent causes of a noisy laptop.

1. Heavy Duty Causes a Noisy Fan to Work: When a laptop computer is overworked, the cooling fan produces weird noises that are rather unpleasant. If you leave your computer on for an extended period, it will most likely emit the jet engine sound.

2. Fairly Hot Environment: A fairly hot or warm climate could also contribute to a noisy cooling fan. If you spend most of your time in such an atmosphere, your laptop will likely make some unpleasant noises, particularly from the fan area.

3. Blocked Vents: If your laptop isn’t getting enough air, it could sound like a jet engine. It could be due to the surface on which you operate the system.

4. Dust & Fragments: Having clean and clear air vents is related to overheating indirectly. With visible vents, the risk of overheating is reduced. However, certain dust buildup is unavoidable, which should not be a problem.

5. Age: Like other forms of technology, a laptop can quickly become obsolete. Certain components begin to fail to function properly as a result of this. As a result, it may produce some unwelcome noises.

6. Existence of Malware: The presence of malware in your system can cause the cooling fan’s processes to fail. It is just one of several issues that make the fan’s job more difficult.

7. Soft Surfaces: Placing our laptops on our mattresses or other soft surfaces is common for most of us. This action, however, is not recommended because it may cause the system to overheat.

8. Multiple Running Apps: You may not realize it, but leaving your computer on for an extended period can keep several programs running. This, too, could lead to a noisy system.

9. Failing Hard Drive: A laptop’s hard drive can make some loud noises. When it fails, this is noticeable. So, if your computer system is emitting an undesirable sound, make sure to include the hard drive in your troubleshooting.

Why is my computer loud?

When your desktop computer sounds like a jet taking off, fans and the hard disk, there are two possible culprits. When these components get older, wear and tear, dust settle in, and they’re more likely to be loud.

The computer system is a complicated piece of machinery. So, to comprehend the right measures to follow to resolve a certain issue with your laptop, you must first determine the root of the issue. It does not include a computer that makes a loud whirring noise.

As previously noted, the whirring sound could be caused by the cooling fan. Let’s look at some strategies for dealing with unusual noises in your computer system.

How do I deal with my laptop’s loud fan?

Modern computers do an excellent job of keeping their internal temperatures cool. They normally have a single fan that draws in cool air and blows it throughout the machine. The heated air is subsequently evacuated through vents on the back or bottom of the laptop’s case. When everything is working properly, the laptop makes hardly little noise.

The sound of a jet engine coming from your laptop indicates a problem. It indicates that something is amiss with your laptop’s cooling system and that the fan is working overtime to maintain things at a safe temperature. The next step is to determine what is creating this overheated scenario.

How to cool down the fan


Is your laptop propped up on a large blanket? Or maybe on your lap?

Surprisingly, your lap isn’t the greatest spot for a laptop. Clothes, blankets, rugs, bed sheets, pillowcases, and cushions are excellent heat insulation materials. As a result, sitting your laptop on them can trap heat under the laptop, causing it to overheat. Not to mention the potential of burn injury from using your laptop on your lap for extended periods.

1. Check where your laptop is placed.

A flat, smooth surface, such as a desk or a lap tray, is always the best location to put your laptop. The bottom of your laptop should not touch the surface as much as possible. Check to see if the unit’s rubber feet on the bottom are still intact, as these raise the device slightly from the surface, letting air circulate through the bottom and keeping the chassis cool.

2. Kill running processes

Kill Running Processes

Several startup programs are one source of overheating in a computer system. When these programs are kept running for an extended time, the computer can generate heat, leading to overheating. So keep an eye out for any unwanted running apps and terminate them.

Fans can go into overdrive if too much strain is placed on the hardware, particularly the GPU and CPU. Suppose you’re playing a very graphics-intensive game or working with an application that puts a strain on your CPU, for example. In that case, you might notice your laptop suddenly making loud noises again (e.g. 3D-rendering programs, compilers, data mining programs, etcetera).

In this scenario, the easiest solution to resolve the overheating problem is to terminate the heavy tasks causing your laptop to overheat. These tasks can be completed with the Task Manager in Windows or the Activity Manager in macOS. It is especially handy for Windows customers who have laptops that generate a lot of noise during startup, which is frequently caused by many superfluous starting routines that run every time they turn on their computers.

3. Clean your laptop.


Clean Your Laptop

Dust, hair, and ash can clog up your laptop’s fans, causing them to malfunction. They also decrease airflow within the device, causing everything to run hotter. You might need to clean the insides of your laptop if this happens manually. If your laptop is still under warranty, you can take it to a service shop or do it yourself.

You’ll need a can of compressed air, a screwdriver, and a little soft brush if you want to do it yourself. First, blow out as much dust as you can from your laptop’s vents with compressed air. Make sure you’re just using the air in short spurts. Then, using the brush, clean away any remaining dust that the air couldn’t reach. The screwdriver is used to open up your laptop; only do so if you’re familiar with your laptop’s internals to avoid unnecessary harm.

4. Make use of a blower

A blower is a device that uses air to force dust or other similar particles from the surface of a cooling fan. To keep the cooling fan free of dust, use a blower. Turn off the computer system and use the blower to remove any particles or dust.

5. Use Thermal Toothpaste

If the noise is caused by overheating, thermal toothpaste may be beneficial. To lower the temperature of the computer system, apply a small amount of thermal toothpaste to the C P U.

6. Check Voltage, Power Supply, and Settings

Overheating can be caused by the voltage and power supply delivered to the computer system and the power settings, resulting in unusual computer noises. This can happen if these factors aren’t in good working order. As a result, make sure the laptop’s voltage, power supply, and settings are all working.

7. Control the vibration

If the noise is caused by the hard disk vibrating against the computer chassis, you can choose this option. The first step is to locate any rubber substance. Cut it into thin pieces and lay it between the computer case and the hard disk once you’ve found one. Check out this one for a good option that will readily stick to the application’s surfaces.

The source of unusual noises is frequently more sophisticated than simple. In such a case, enlisting the help of a professional is the best option. They are best positioned to determine what will work and what will not.

What is the best way to make my computer fan quieter?

Working with your computer system in a well-ventilated environment and keeping the fan vents clear are the simplest ways to keep your computer fan quiet. Also, make sure they’re in good working order.

2. Make sure the fan vents aren’t blocked.

Because the cooling fan is the most common source of computer whirring, it’s recommended to maintain these fans clean. It is likewise true of the fan vents. The cooling fans’ effectiveness can be harmed by the accumulation of dust and other similar particles. As a result, certain sensitive components in the system may become overheated.

To this end, keep the fan vents free of dust and other particles that obstruct the free passage of air through the system. It is required for the computer to function properly in terms of self-cooling.

Ensure the computer is turned off and all power supplies are disconnected before proceeding.


3. Check if the cooling fans are working properly.

Check If The Cooling Fans Are Working Properly

When all of the preceding processes have been followed to a tee, the cooling fans must be checked for good operation. The startup and typical spinning of the fans are what you’re looking for at this time. If you notice that the fans are still making noises, they need to be changed.

Most cooling fans can be replaced individually; however, if the power supply fan malfunctions, the best action is to replace the entire power supply component.

Attempting to repair the power supply unit might be intimidating and potentially dangerous. Furthermore, if a power supply unit overheats, it will not provide enough power to critical computer components. As a result, a replacement will be more appropriate than a repair.
