5 Steps to Silence a Noisy Laptop Fan

5 Steps to Silence a Noisy Laptop Fan

A laptop cooler is an important element that should work smoothly. A laptop, like a portable computer, is very demanding on every detail of the design. Especially the cooling system should be treated demandingly and responsibly. The laptop fan dissipates heat and maintains the desired temperature of the device. This ensures uninterrupted operation of the system and prevents overheating. The cooler is always noisy, as it is a small fan that drives air to cool the "insides" of the laptop. When it's working properly, you should only hear a slight buzz that won't bother you, but if you start to hear it work louder and more often, you should probably take a closer look at it.

The increased fan noise is certainly very annoying and is undoubtedly abnormal. Let's see what can befixed so that the fan doesn't make as much noise.

Why does my laptop fan make a rattling sound?

A laptop fan is a moving part that can wear out. Loud or clanking sounds that you hear from a fan are a sign that the fan mechanisms are worn out or deformed. There are a few things that can speed up this kind of damage, including dust or improper ventilation.

Dust accumulation

One of the things that can clog up your cooling system is the accumulation of dust. When a large amount of dust accumulates inside your laptop, it can prevent the fan from working properly and even cause the device to break down. This creates extraneous sounds which heard from the fan.

Dust can also trap heat, which makes it difficult for a PC to cool. You may notice that the fan is running a lot more than usual and is making a lot of noise. This is because the fan has trouble running air through the honeycomb of the thermal module to dissipate the heat, and for this it has to exert more effort. When overloaded, the fan fails more often.

Insufficient ventilation

To properly dissipate heat, you need to ensure proper ventilation for the fan to run. This removes hot air from your laptop. To do this, it is necessary to install a laptop at the workplace so that hot air leaves the perforation holes unhindered.

This involves using a laptop on flat and clean surfaces, such as desks and laptop stands. It is not recommended to use the laptop on fabric surfaces, such as a bed, or on top of blankets. These fabric surfaces can block your laptop's vents and retain heat.

Physical malfunction or wear and tear

Laptop fans are mechanical moving parts that are in working order all the time, as their main function is to cool system elements from overheating. The natural wear of the cooler is another reason why the fan in the laptop makes noise. The cooler at high speeds begin to beat, which leads to the emergence of extraneous sounds. In order for the laptop to work stably and without braking, it is necessary to regularly monitor the condition of the fans, clean and maintain the cooling system of the laptop with the replacement of thermally conductive paste (thermal paste) and thermal pads.

Don't delay the problem

A worn or deformed fan can still run for a while despite the increased noise. Obviously, it's just going to work less efficiently and louder. Even if you can tolerate the noise, this problem should not be ignored.

Problems with the cooler threaten to overheat important components of the motherboard, for example, with a video chip. Reballing a laptop video card is an expensive repair. And replacing a laptop motherboard with a new one can be problematic. If you do not eliminate the malfunction with the fan, then the northbridge or other chip can burn out from constant overheating, and this is an additional cost when repairing the laptop.

To prevent these malfunctions, it is necessary to regularly diagnose and clean the laptop at least 1 time per year. If there are animals in the house or the laptop is often used in dusty rooms - cleaning the laptop from dust should be performed every six months.

What to do with the knocking of a laptop fan

1. Clean the air vents and fan
   
   Sometimes cleaning the fan vents can solve the problem. If you haven't cleaned the inside of your laptop in a while, take the time to do so.
   
   Engineers of our service recommend cleaning the laptop at least once a year. Carefully choose a service or specialist, preferably proven, with good experience and not at the lowest price per service. Do not disassemble and clean the laptop yourself, without having the proper skills and experience.
   
   Perform preventive cleaning on any laptop that is six months old or older. This will significantly increase the life of the laptop.
   
   
2. Replace thermal grease
   
   All systems can be clean, the fans are absolutely serviceable, however, dried thermal paste leads to a significant decrease in the ability of the cooling system to remove heat.
   
   Thermal grease is used in all computers as a thermally conductive compound. It is used to eliminate gaps between radiators and heat sources, ensuring efficient heat transfer and dissipation. We can usually find it in places where heatsinks come into contact with the CPU and GPU. The old material must be carefully removed, replacing it with a new one. Such work requires disassembling the laptop with the dismantling of the radiators. Therefore, we recommend that you contact the professionals.
   
   
3. Delete has unnecessary processes
   
   When your laptop's fan is overloaded, it could be a sign that you're overloading your processor or graphics card. This may be due to background processes that you are not aware of. They can consume and load CPU processing power. This, in turn, creates a fair amount of heat, which the fan needs to exert more effort to dissipate.
   
   You can try to give away background processes from Task Manager to free up this space for processing, which can help keep your system running smoothly.
   
   
4. Run programs check
   
   If any problems with the cooling system are detected, it is recommended to eliminate them as soon as possible to prevent overheating and subsequent failure of components. Updating the software usually helps to optimize the system for stable operation, so we recommend periodically checking and updating the software to the latest versions in the laptop.
   
   On many devices, Bios affects the activity of the cooler. Turn off the device and turn it back on. As soon as the boot screen appears, enter the BIOS menu. This can be done using the Del, F2 or ESC keys. The combination depends on the model of your device. Going to the main menu, select the Power tab responsible for the temperature of the processor and cooler. Now you will need to find the CPU Q-Fan Control and CPU Fan Profile . It is important that the first indicator is active. The second parameter is responsible for the intensity of fan rotation:
   
   
   • Silent – the minimum amount of charge is spent;
   • Optimal - the cooler will begin to turn on at the time of increased load on the laptop (often this happens when starting online games);
   • Turbo – continuous operation of the cooling system.
   
   
   For Lenovo owners this advice may not be relevant.
   
   The easiest way to find out the cause of the problems and eliminate their consequences is to use programs. You can check the serviceability of the laptop cooler using the SpeedFan program. SpeedFan is a special program for testing all installed fans, will allow you to quickly establish the state and degree of operability of the device without disassembling it. Using this utility, the user gets full control over the operation of the fan, and can adjust the rotation speed at a particular temperature.
   
   Another useful application is AIDA64. It is preferable to use it for those who are fond of heavy games, especially online.
   
   
5. Replace the fan
   
   Replacing the fan with a new one will definitely solve your problem. Usually you need to get the exact part to replace the broken one.
   
   There are many models of fans, but when choosing, you should be careful. The list of parameters that you should pay attention to will help in the selection:
   
   
   • Model: The fan must be strictly appropriate to the model of the device.
   • Brand: Coolers should be purchased only from the manufacturer. If you use a Lenovo fan, you should buy this brand of fan. If you try to apply a part, for example, from the manufacturer HP, you may encounter a compatibility problem.
   • Productivity: The higher the productivity parameters, the more power and better the cooling of the system.

And remember, laptop repair always requires special experience and some training.
