Do you ever wonder or ask yourself, why does my laptop sound like a jet engine? If you have such a problem, you need to check the cooling fan of your laptop. While there could be other factors responsible for this, the cooling fan stays at the top of the reasons for such technical issues.

This article will help you discover why a laptop sounds like a jet engine on startup. Furthermore, we will show you some effective tips for easily and quickly solving this issue.

Why Does My Laptop Sound Like a Jet Engine?

One major reason a pc would sound like a jet engine on startup or whilst using could be due to dirt or dust around the cooling fan. While this is true, some other factors may include a faulty hard disk or overheating from inside the machine.

There could be some additional factors. However, a problem like this mainly occurs from the cooling fan. Usually, it indicates dirt on or around the cooling fan. Let us now take a more detailed look at these common reasons for a noisy laptop.

  • Heavy Duty Results in a Noisy Working Fan

Usually, when a laptop computer gets overworked, the cooling fan tends to generate strange noises that are quite unpleasant. Using your computer system for extended periods will likely create that jet engine sound.

  • Fairly Hot Environment

A fairly hot or warm environment could be another factor that contributes to a noisy cooling fan. In this environment, there is a tendency for your laptop to generate some unpleasant noises, particularly from the fan region.

  • Blocked Vents

If your laptop is not getting adequate air, it could produce jet-engine-like noise, which could be due to the surface on which it is placed.

  • Dust & Fragments

Having clean and clear air vents is indirectly proportional to overheating, which means that a lesser risk of overheating comes with clear vents. However, you cannot avoid inevitable dust buildup, which should not cause any issue.

  • Age

Similar to other forms of technology, a laptop can go out of date quite fast. Once this happens, specific components tend to stop working efficiently. As a result, it could develop some unwanted noises.

  • Existence of Malware

The existence of malware in your system can pose failure to the processes of the cooling fan. This is just a part of other problems, making the fan work heavier.

  • Soft Surfaces

For most of us, it is quite easy to place our laptops on our beds or similar soft surfaces. However, this action is not advisable as it can cause the system to overheat.

  • Several Running Programs

You may not know this, but leaving your computer system on can keep several programs running for a long time resulting in a noisy system.

  • Failing Hard Drive

The hard drive of a laptop can also generate some loud noises, which is noticeable when it is failing. So, if you get that unwanted sound from your computer system, ensure to include the hard drive in your troubleshooting.

Strange Noises in Computer Solution

The computer system is quite a complex machine. So, for you to understand the proper steps to take to solve a particular issue with your laptop, it is crucial to understand the actual source of the problem. A computer making loud whirring noise is not an exception to this.

Strange Noises in Computer Solution

As stated above, the cooling fan could be the most likely cause of the whirring sound. Let’s consider some tips you can employ to tackle such strange noises in your computer system.

  • Use a Blower

A blower is a tool that uses air to force dust or some other similar particles out of the cooling fan’s surface. Use a blower to keep the cooling fan from dust. Turn off the computer system and blow off particles and dust with the blower.

  • Thermal paste Application

Suppose the noise results from overheating, then applying thermal paste can help the situation. Just use a small quantity of the thermal paste on the C P U to reduce the temperature of the computer system.

  • End Unwanted Running Programs

One thing that brings about overheating in a computer system is several startup programs. Often, if these programs are left running for a long time, the computer could generate heat and result in overheating. So check out for such unwanted running programs and end them.

  • Check the Voltage, Power Supply, and Settings

The voltage and power supply conveying into the computer system, or even the power settings, can also bring about overheating, leading to strange noises in the computer. This can occur if these factors are not in their proper state.

Check the laptop’s voltage, power supply, and settings to ensure they are in the right state.

  • Control Vibrations

You can use this option if the noise results from the continuous vibration transfer of the hard disk to the computer case. The procedure here is to find any rubber material, cut it into thin strips and place it between the computer case and the hard disk. For a good choice, check out this one that will stick easily to surfaces on the application.

  • Talk to a Professional

Often, the cause of such strange noises could be more technical. In such a situation, the best option is to involve the assistance of a professional. They are in the best position to decide and know what would work or wouldn’t.

How Can I Make My Computer Fan Quieter?

The simplest way to make your computer fan stay quiet is by working with your computer system in a well-ventilated area and keeping the fan vents clear. Also, ensure they are working correctly.How Can I Make My Computer Fan Quieter

It is much better and cheaper to prevent damages than repair or fix them. We have included some of the most effective tips to help you maintain a quiet computer and spare yourself the expense of fixing them. In addition, they will help you sustain your laptop’s overall soundness in the long run.

Work in a well-ventilated Area

Working with your computer system in a cool environment is the first thing to keep in mind before considering the system’s internal parts. To do this, always make sure your computer system is placed on a levelled and smooth surface while working with it. Such a surface may include a floor or a desk surface.

While working with your laptop, avoid placing it on a soft surface like a bed or a foam surface. Furthermore, you must avoid surfaces such as that of a carpet. Doing this will allow cool air to flow throughout the computer. This applies to a desktop or a laptop computer.

Keep the Fan Vents Clear

Since the cooling fan is the most common cause of the whirring sounds in computers, it is best to keep these fans clean. And this also applies to the fan vents. The dust buildup and other similar particles can reduce the cooling fans’ effectiveness. This, in turn, can result in the overheating of specific sensitive components in the system.

It would help if you always kept the fan vents clear of dust and particles that hinder the free flow of air through the system. This is essential to allow the computer to perform proper self-cooling.

Before performing this action, ensure the computer is turned off and disconnected from all power supplies.

Confirm the Proper Operation of the Cooling Fans

When all the above steps are followed, what follows is to confirm the proper operation of the cooling fans. At this point, what you are looking out for is the startup and normal spinning of the fans. If you observe that noises are coming from the fans, they need replacing.

It is possible to replace most cooling fans individually. However, if the fan for the power supply is faulty, the right course of action in such a case is to replace the whole power supply component.

Attempting to fix the power supply unit can be daunting and possibly risky. If a power supply unit is overheating, then, in that case, it will not dispense adequate power to essential elements in the computer system. Therefore, instead of a repair, a replacement will be more appropriate.

Bottom line

One of the most common computer systems issues is an unpleasant whirring noise. This is why most people would want to ask, why does my laptop sound like a jet engine? The most common reason this could occur is a faulty or dirty cooling fan. Also, the issue can generate from overheating or damaged hard disk.

Keeping your fan vents clear and working with your laptop in a well-ventilated area is an effective way of maintaining a quiet computer system.
