If you’ve ever been startled by your computer suddenly sounding like a jet engine, you’re not alone. This noise can be alarming and might have you worried about your device’s health. But don’t panic! While a noisy computer can be a symptom of an issue, it doesn’t always mean your device is on the brink of failure.

This guide will delve into the reasons why your computer may sound like a jet engine and provide practical solutions to fix it.


Whether new, refurbished or second-hand, computers are bound to make strange noises at some point, and this is a clear sign that your processor is getting hot. Overheating can be due to numerous factors, from dust blocking air vents in the system’s ventilation to disk troubles.

This problem is more prevalent in laptops, as they are designed with portability in mind, trading off an excellent cooling system for ease of transportation. This article aims to help you understand and resolve the irksome noise coming from your computer without further ado.

Dust buildup within the computer can impact cooling efficiency. A study by Enermax found that excessive dust can reduce a computer’s cooling capacity by up to 50%, leading to increased fan speed and noise.

Common Causes Of Loud Computer Noise

The root causes of a noisy computer system are varied, but they all boil down to a few common culprits. Let’s explore them in greater detail.

1. Dust And Dirt Buildup

The accumulation of dust and dirt in your computer can block its cooling fans and ventilation system, causing it to overheat. When the processor gets heated, the cooling fan takes on the responsibility to dissipate the heat.

However, if the fan’s function is hindered due to the clog, it may result in your PC sounding like a jet taking off. Regular cleaning of your computer’s ventilation system can prevent this issue.

Inefficient thermal management can lead to increased fan speed and noise. A report by TechRepublic suggests that inadequate cooling systems or blocked air vents can cause the computer’s fans to work harder to dissipate heat, resulting in jet-like sounds.

2. Overheating

Computers, especially laptops, are prone to overheating due to their compact design. Overheating your laptop can cause the fans to work harder, leading to loud noises. Investing in a cooling pad can drastically improve your computer’s heat dissipation, allowing you to run heavy-duty applications without worrying about your processor overheating.

3. Fan Issues

Apart from dust and overheating, worn-out fan motors and fan blades can also cause your computer to emit loud noises. It’s important to inspect your fan regularly and replace any faulty parts as needed. To avoid further damage, it’s recommended to hire a computer repair technician for this job.

4. Hard Drive Problems

Issues with the hard drive can also cause your computer fan to produce loud noises. Hard disks, particularly older ones, can generate low-pitched noises when running heavy-duty tasks. If the noise persists even after cleaning and inspecting the fan, it’s best to check the hard drive.

According to a study by Cornell University, computer fans can generate noise levels ranging from 20 to 60 decibels (dB), depending on their speed and efficiency. Higher fan speeds often result in louder noise.

How To Fix A Noisy Computer

Now that we’ve looked at the common causes of a noisy computer, let’s discuss the possible solutions.

1. Cleaning The Computer

Start with cleaning the built-in fan and the ventilation system. After powering down and unplugging your laptop, open it up and carefully clean the fan using a soft brush or canned compressed air can. Remember to be gentle to avoid damaging the delicate components.

2. Checking For Hardware Issues

If the loud noise still persists even after cleaning, it’s time to investigate potential hardware issues. Loose internal components around the cooling fan can cause your computer to make loud noises. Inspect these components and tighten them if needed. For this task, it’s best to seek assistance from a professional if you lack experience working with computers.

As computer hardware ages, fans may become less efficient and noisier. A report by TechSpot highlights that worn-out or failing fans can contribute to the jet-like sounds emitted by the computer.

3. Replacing Or Repairing Fans

If the noise is attributable to a faulty fan motor or blade, replacing or repairing the fan can fix the issue. Again, it’s better to hire a computer repair technician for this task to make more noise and avoid causing further damage.

4. Checking The Hard Drive

If none of the above-mentioned solutions work, checking your hard drive for issues is the next step. If your hard drive is making unusual or weird noises while running heavy-duty tasks, it could be a sign that it needs replacement.

5. Adjusting Power Settings

Often, a poor power supply can cause a computer to produce loud noises. Adjusting the laptop fan power settings or using the correct adapter can alleviate this issue.

6. Updating Drivers and Software

Outdated drivers and software can also cause your computer to work harder than necessary, resulting in loud noises. Regularly updating your drivers and software can keep your computer running smoothly and louder noise more quietly.

Overclocking, a practice of running computer components at higher frequencies than intended, can generate excessive heat and strain the CPU. According to PCMag, high CPU usage from resource-intensive tasks can also trigger increased fan speed and noise.
