Dell Inspiron 15 7000 is a computer with a good display with perfect inches for the screen; it has a faster CPU frequency, and the storage is quite remarkable for use in the office. The fan noises from the Dell Inspiron 15 7000 result from overheating the CPU that causes the fan to work faster to cool the machine that causes damages to the fan, and reduces the rates of working of the computer.

Even though it is normal for the fan to make noise when running, it is good to find the noise causes and fix them if it is because of some faults. Loud fan noises indicate that the fan has problems or that the computer has issues that make the fan run faster, making the noise.

Below are the possible solutions to the Dell Inspiron 15 7000 fan noise, it will take you through the troubleshooting process of fan noise.

However, before fixing the noise, it is essential to identify the noise causes to make the fixing process more manageable in your machine. Follow the article to identify the causes of the noises and how to fix them.

Causes of Dell Inspiron 15 7000 fan noise

1. CPU is getting hot

Dell Inspiron 15 7000 CPU is getting hot

When the CPU gets hot after a long time of usage, it tends to make the fan strain in working as it works hard to blow air into the machine for cooling. When the CPU is hot, it makes the fan run faster to remove the heat; the process of faster movement of the fan causes it to make noise in the laptop.

2. Availability of dirty particles

When using the laptops in an open environment that can easily access dust, the dust particles tend to accumulate in the air vents, CPU, and other parts that can cause either overheating of the machine or prevent the flow of air in and out of the machine. Therefore, the dirty particles make the fan work hard to blow air through the dirty surfaces making noise.

3. Faulty bearings

Faulty bearings

A bearing with faults creates loud noises in the laptop when the fan runs faster when blowing air. Sometimes it causes grinding noise due to the effects from the motor where its lubrications do fail in some cases. Faulty bearing causes overheating of the computer, making the fan make noise when straining to blow the air for cooling the computer.

4. Faulty hard drive

A faulty hard drive fails to work, causing loud grinding noise when the laptop gets access to the hard drive. Sometimes the hard disc displays data errors in the laptop that results from the fan’s noises. A faulty hard drive fails to perform its functions that lower the higher temperatures in the laptop, forcing the fan to work alone causing it to make loud noises.

Solutions of Dell inspiron 15 7000 fan noise

1. Eliminate the processes in the laptop

Some processes in a laptop cause overheating of the CPU as they are heavy and light tasks in the machine. When the processes are running, the CPU then works harder hence overheating that later makes the fan run faster when trying to cool down the laptop, which causes noises.

Therefore, to reduce the noises in the fan, eliminate all the processes running in the laptop that mainly occur when booting the laptop. To eliminate the processes, open the task manager and close all the processes in the processes tab.

2. Buy a computer cooler

A cooler is a device that helps cool the laptop in place of the fan, as it also helps the fan reduce its work. Therefore, when trying to reduce the noise from the fan, use a cooler to cool the laptop. A cooler not only reduces the heat in the laptop but also enhances the user’s comfort.

This Isn’t just a Purchase.. A Cooler Can Increases Your Laptop Battery Health Up to 3x.

There are three types of coolers that one can use to cool laptops; coolers include active coolers, passive coolers, and multipurpose coolers. Active coolers provide an extra flow of air into the laptops using small fans, while the passive coolers use thermal conductive materials to draw away the heat.

3. Clean the internal components of the laptop

Fan noise results from dust that accumulates in the air vents and some other parts in the fan and the laptop. The noise occurs when the fan is blowing air hard, and the air forces itself out through the dust particles in the air vents.

Best Cleaner For Your Laptop

Laptops quickly pick up grime, dust, dirt, and smudges. To keep them clean, you’ll need several tools specific to electronics. These are the best tools to clean your laptop from keeping crumbs out of your keyboard to removing smudges off of the touchscreen.

After blocking the flow of air in and out of the laptop, the CPU will overheat, and it forces the fan to work again harder to reduce the heat inside, which causes noise. Therefore, to reduce the noises, consider cleaning the computer’s internal parts since they attract dust that accumulates into them, causing overheating of the machine.

4. Install software

Dell Inspiron 15 700 machines allow the user to take control of the fan speed using the software. Using the software reduces the fan noises; however, the software affects the laptop as it will make it be hotter and lower its lifespan.

Moreover, the software can know the whole information in the machine, so it is better to use the speed fan than the software. Speed fan controls the fan’s speed and can increase if it is shallow or reduce when it is compelling faster.

Frequently asked questions:

  • What preventive measures to take when fixing the fan noise in the Dell Inspiron 15 7000 laptops?

When fixing fan noise in a laptop, consider taking preventive measures to avoid causing damages to some parts of the laptop and injuries to your body. The preventive measures are as follows:

i. Always keep off the computer before opening the internal parts by disconnecting the power cables before using the compressed air to clean the machine since the compressed air can damage the machine when it is on.

ii. Ensure you clean the air vents by spraying the compressed air but do not blow air with your mouth since air from the mouth contains moisture that can damage parts that are not compatible with water. Also, avoid using vacuum cleaners and blowers as they cause static and damage the computer’s electronic parts.

iii. Avoid opening the power supply units that have a fan when trying to clean. Opening the power supply can destroy the cabling direction and the cables can fail to provide power to the computer and get the computer damaged later. It can either provide excess power or less power.


Dell Inspiron 15 7000 fan noise is normal sometimes since fans have to propel to blow air in and out of the machine. The process of compressing the fan causes the production of noise. However, the noises can turn and be loud, which affects the regular operation of the user. The article above shows the causes of the fan noises and the possible solutions for reducing the noises.

Therefore, follow the guide carefully to identify why a fan makes noise in a Dell Inspiron and how to fix it. It is always good to take preventive measures when fixing the noises to avoid damaging some other machine parts.

To prevent the noises, keep checking the system frequently and remember to clean the air vents. If the fixing process fails to work in your machine, consider consulting a technician to help you fix the problems.
