What is the function of the fans inside the Laptop?
The function of a fan is simple but extremely important. It keeps the environment cool and calm by pulling cold air through vents and keyboard holes. This cold air is circulated all over the electrically connected components and keeps cool as they are vulnerable to high temperatures.
Most of the time, people purchase laptops based on their required specifications and quality of the components and ignore the performance of the cooling fans in the laptops. Therefore, they experience an unpleasant event in damage and fires inside the laptops.
Typically, Laptop fans remain calm and quiet, but this is not the case. Someone must have an understanding of the reasons why a laptop fan makes a loud noise. In the following line, we will discuss the common reasons for the loud sound produced by laptop fans.
Why a Laptop fan makes loud noise?
You may have observed the fan sound in a brand-new laptop, making almost zero noise. But, sometimes, fans suddenly produce a louder sound and achieve a supersonic speed. So, here are the top reasons why a laptop fan starts rattling and has a loud noise:
1. Dusty Environment
When you have a congested workplace, you will have no vent for fresh air. Dust inside the room gets to settle in the Laptop, and the fan starts getting stuck. Resultantly, heat builds up, and Laptop struggles, and performance goes down. Therefore, fans and other debris starts making a buzzing sound.
2. Physical Obstacle
People habit using laptops on their laps, pillows, and blankets. These create a physical blockage of air circulation within laptops, and fresh air doesn’t come, which keeps the temperature controlled.
3. Extensive Multitasking
When buying a laptop, quality and best specifications are considered so that they can run a lot of programs at the same time. This multitasking lowers the performance and applies extensive pressure over the components. Opening more than ten web tabs can impede the speed of fans. It is considered one of the common reasons for laptop fans making a loud sound.
In the online world, attacks on computers and laptops are always the talk of the town. Free and cracked software are reasons for such hacking. This malware goes deep into the system and steals critical information. Due to this malware, Laptop tries to keep the level of performance consistent, and the fan tries to keep it cool and makes a loud sound.
5. Heavy Software
Cryptocurrency mining and AAA games demand heavy software and a lot of power consumption. If you are doing all this on your Laptop and it’s working well, then luckier you are. During crypto mining, a lot of heat is emitted through the CPU, and the fan speeds up to expel it through vents, which compels the fan to make a loud sound.
6. Hot Environment
If the workplace has ventilation points, it will be easier for the fresh air to come into the room. It will keep the system’s temperature on the lower side, and the fan remains calm and cool.
On the other side, playing heavy games on hot summer days outside the room seems a good idea if the fan doesn’t make a sound. But, the loud sound of a fan, if observed, then neighbors may think it’s a jet engine instead of a laptop fan.
7. Too Hard CPU
Sometimes, the fan doesn’t have any problem at all. Suppose an application eats more CPU resources than required, which causes the building up of heat inside the Laptop. So, at this time, when a fan makes a loud noise, then it indicates a more than expected share of CPU resources.
Methods to Make Your Laptop Fans Quieter
Here are some easy but crucial steps you can follow to stop the fan from making a loud sound, maximize the performance, and vent the heat completely;
Method – 1: Remove Dust from Fan of Laptop
A newly purchased laptop works cool and quiet. But, with time, it starts accommodating dust particles inside the fan and other connected electrical components. These may include unmanageable craps and insects, which will hinder the proper flow of air through the components. As a result, the temperature gets higher, and performance goes down.
The good news is that you don’t have to be a computer mechanic to clean this dust. All you need is an air blower or can have compressed air which is available in the stores.
Using this compressed air is to blow it through the vents inside the Laptop. It will not only clean the motherboard but also the noise of the fan is dramatically reduced.
Disassembly of a laptop and its components will be a plus point for you if you hold knowledge of the internal parts of a computer. Doing this must not affect the warranty, and be careful about fragile cables.
Method – 2: Close Heavy Applications
most people open various programs concurrently, i.e., web browsers, games, editing, and rendering software. This act will put a lot of stress over the machine – causing a fan to make a loud noise.
Sometimes, just like applications in android phones, programs remain active in the background. Shutting these programs down will positively reduce the noise of the fan and increase the efficiency and performance of the Laptop.
Just right-click on task manager on Laptop’s taskbar. When the task manager is open right, click on the program, which is draining energy and occupying the memory of RAM. A popup will appear to end the task, hit it, and close the program.
Method – 3: Purchase a Laptop Cooling Pad
Suppose you are comfortable with desktops and static machines, then purchase a cooling pad for your Laptop to provide air circulation inside it. Fan coolers with vacuum technology will suck all the heat and give a cooling effect to the Laptop. It will enhance the performance, reduce stress over the fan and diminish the noise of the laptop fan for some time.
Cooling pads are considered essential parts of laptops used to run heavy 3D games, rendering software, and other highly complex applications. But the sad thing is that a cooling pad is not a final solution if the fan is still making noise.
Method – 4: Remove Malware
Malware is thrown through the internet on the computers/laptops to hack them and fulfill the required purpose. These malware work behind the scene, i.e., in the background, and absorb the energy and memory of RAM. This action will cause the system to slow down and don’t follow the given commands. The laptop fan will have to make more effort to reduce stress and make more noise.
But, how will you know whether malware is working or not? Simple to check malware is to go to the task manager and look at the programs which are stranger to you, then remove them quickly by right-clicking and end the process. Furthermore, you can collect information about such programs from Google. It doesn’t mean that if you didn’t find any malware, it’s not present. The best solution for invisible malware is the usage of Antivirus. So, scan your Laptop routinely to avoid any risky malware.
Method – 5: Applying thermal paste inside the Laptop
Most users don’t know the thermal paste for the CPU of the Laptop is essential, and it can keep the temperature 0-20 degree. For example, Arctic Silver 5 – you can apply this thermal paste to control the temperature up to 20 degrees. These thermal pastes work best for the laptops used for rendering and 3D printing. Otherwise, laptops will get heated. It’s simple as that. Using this thermal paste will reduce the noise of the laptop fan.
Method – 6: Install an SSD Disk on Laptop
SSDs are popular nowadays, and they are the best replacement for HDDs. These SSDs enhance the performance while opening a lot of web pages and give breath to RAM as well.
All of the new laptops have the option to install an SSD. The only requirement to handle this procedure is matching the motherboard connectors with the connectors of the SSD.
This method will require a capital cost for purchasing an SSD, but it will eliminate the noise of the laptop fan in the longer run.
Method – 7: Keep the Laptop have breath
Keep in mind – give some space under the Laptop while keeping it on a table as the vents usually are placed on sides or bottom panels. When you keep using a Laptop on your lap or any soft place, then a tiny rubber pad cannot provide the required space for cooling the system.
Suppose you are addicted to technology and use a Laptop even on a blanket, then it’s not suitable for your Laptop. We highly recommend you to buy a stand for the Laptop or use a large one at least.
Method – 8: Use an Advance Operating system (OS)
It may feel strange to many, but older operating systems have cons that affect the performance of the Laptop. Installing a new Windows 10 in your system will make it faster, and all the options start working instantly with one click.
If you have a great budget, you can install SSD, RAM, thermal paste, and Windows 10. It will surely drastically boost the operating speed and reduce the fan’s noise to zero level.
Method – 9: Control the Speed of the Laptop’s Fan
Our last method is potentially risky as it can make the Laptop overheated and unstable. It is only recommended if you have no other option and are confident enough that the fan’s spin can be made slower and make the laptop fan quieter.
Keep in mind that all laptops don’t have the option of manual control for the fan. Applications such as the lm-sensors and fan control can be used for this task.
If you own ThinkPad laptops, they provide a software named think fan, which controls the fan’s speed. It can download from Github or other repositories.
In this article, we have discussed the most common causes of a noisy fan of laptops and listed the best methods to make your laptop fan quieter.
If none of the above methods work for you to make a noisy laptop fan quieter, then take it to an expert or factory reset the Laptop to remove any malware or hardware issue.
