Is your laptop fan noisy and annoying you? Find out about laptop fan noise, why it happens and what can be done to fix the problem without taking it to the repair shop and spending a lot of money. Sometimes the fixes are easy to do and it can keep your system from crashing.
Having computer issues can be frustrating, especially if it is the same issue over and over again. If your laptop fan is too noisy, you may be able to easily fix it if you choose the right way to do so. The best way to resolve laptop fan noise is to know what causes the problem.
Causes Of Noisy Laptop Fans
The main cause of fan noise in a laptop is overheating. When a laptop is working and starts to heat up, then the fan switches on, which is what it is designed to do. There are several reasons why a laptop can overheat.
If the room you’re working in is too hot, then your computer or laptop’s temperatures can rise, which will trigger the fan. Also, if you are working on a soft surface, such as your bed or your lap, then it can start overheating as well.
If you’re trying to game on your laptop or run a large program that it’s not designed for, that can cause overheating as well. Of course, the fan can be malfunctioning, which will require replacing it. If the fan seems always to be too noisy or a continuous problem, here are 10 ways to fix the problem.
Use A Cooling Mat
If you’re working in a warm room and the fan on your laptop is triggered due to the temperature, buy a laptop cooling mat. The mats have built-in fans, which are usually quiet, and it can help keep your system cooler. Cooling mats are inexpensive, and they can keep your laptop from crashing due to overheating.
A cooling mat is also a good idea if you work on your laptop while in bed or on a carpet. Most laptop designs have the fans on the bottom of the system, so if you’re placing it on a soft surface, you’re blocking the fans. Place the system on a cooling mat while in bed or using it on your lap, so it stays cool.
Run A Virus Scan
The more programs you have open, the harder a laptop will work, which generates heat. Close some of the programs you’re running if they are not in use or run a virus scan to make sure you don’t have malware or viruses running in the background.
If the virus scan is positive, then isolate the virus or malware by using the laptop’s virus protection software to get rid of it. If it doesn’t show anything, then use a cooling mat or put your laptop on a hard surface like a desk. Using your laptop on a soft surface can quickly overheat your system.
Clean The System
Another reason for an overheating fan is dust in the vents or your computer. There are several ways to clean the vents and clean the inside of the laptop. If you only want to clean the vents, use a cotton swab or an old paintbrush to clean the individual slots.
To get inside of the system, buy canned, or compressed, air and blow the air through the vents to clean it out. If you have a small screwdriver, you could open the case and brush out the dust bunnies from the inside of the system to ensure it is clean. However, a can of air should work well for cleaning it.
Upgrade Your System
While you may not need to buy a new laptop, you can upgrade some of the components to keep yours from overheating. The best way to tell if you need a new processor or RAM is to open the task manager on your operating system.
If you’re running Windows, this is done by pressing CTRL+ALT+DELETE simultaneously. When it opens, select the “Performance” tab. This tab will allow you to find out how of the system’s resources the processor, RAM, and the storage is using.
If the bar is near or touching the top, then you’re using 100% or slightly less of those resources. You may need to replace the processor, add more RAM, and/or more storage. You’ll need to know what type of processor, how much RAM and storage that you currently have before considering an upgrade.
In some cases, especially if you’ve had your laptop for a while, buying a new system may be cheaper. However, if you want to upgrade what you have, find a good computer shop and take it to them for help.
Replace The Fan
If your computer is overheating or the fan continues to make noise no matter what you do, you may need to replace the fan. Like all moving parts, fans can wear out, so you will need to replace it. A laptop fan isn’t very expensive and having one replaced shouldn’t be very costly.
The Three Main Symptoms Of A Malfunctioning Laptop Fan Are:
• Overheating – If the fans are not working correctly, then the system will easily overheat.
• System shutdowns – An overheating laptop, or PC, can trigger Windows to shut down the system to prevent it from crashing and losing data. If it was the main CPU that triggered a random shutdown, then you may get a message on the system stating, "CPU fan failure." If you get that message, or anything similar or if your system is shutting down randomly, take it in to have it diagnosed, and the fans replaced.
• Fan noise – Malfunctioning laptop fans will often make noise if they are failing. However, they could go out without making a sound. So, if you don’t hear a fan starting to keep your system cool, have it checked out.
Check The Battery
The battery of a laptop isn’t meant to be stored at full capacity or when it is fully drained. Many people leave their laptops plugged into the charger, not using the battery at all, which can reduce the battery’s life. As the battery starts to fail, it generates heat, and you may hear laptop fan noise.
Consider replacing the battery if it is getting too hot or remove it from your system and leave it plugged into the charger. Removing the battery should remove the overheating problem, and your system should still work fine. If you do replace the battery, unplug your laptop and use the battery, so it continues to operate correctly.
Defrag The System
If your laptop is running hot and its performance has slowed, then you may want to defragment your hard drive. Files stored on a hard drive can fragment when you do things like deleting them, move them from one folder to another or change the file's name.
These small pieces of files are scattered throughout the hard drive and can cause your system to slow as it looks through the drive searching for the information you want to pull up. Defragging brings the scattered pieces back together and forms them in columns and rows.
After defragging, the system will run quicker and not overheat as its searching for the file you want. Although Windows systems (7,8 and 10) automatically defrag the system, it isn’t always consistent. You should defrag the hard driveabout once a month to keep your drive in order.
Check Compatibility Of Operating System
Upgrading the operating system can sometimes cause a laptop to overheat because the new OS is incompatible with the computer. For instance, if you were using Windows 7 and upgraded to 10, then it may be using more resources, which can cause a system to overheat.
Similarly, if you upgraded the hardware with more RAM or a new processor, then the system may not be able to handle the upgrades adequately. Consider using a cooling mat or take your system to a repair shop to find the reason for overheating and get it fixed.
Overheating Graphics Card
If you notice lines or snow suddenly appearing on your screen, then your graphics card could be overheating. There are several reasons for an overheating graphics card, including overclocking the system, faulty drivers or bad air flow.
A new graphics card may not be necessary if you fix the air flow or stop pushing your system’s resources too hard. However, if you get a blank or black screen, it may be time to invest in a new graphics card.
Buy A New Laptop
If you’re still running a laptop that has Windows 7 or 8, then you may want to consider a new system if you plan to update to Windows 10. An outdated system will have problems running all the resources that come with the updated Windows OS.
If your system runs too slow or you need more storage, you could upgrade the hardware. However, if you’re planning on upgrading the processor, you may be able to buy a new laptop for the price of most new processors. Also, a new system should have more RAM and a larger hard drive your older laptop.
To resolve laptop fan noise, one of these 10 solutions should be able to fix the problem. Most of the time the issue is simple to fix, such as cleaning the air vents, and with regular maintenance, you won’t need to worry about an overheating laptop.
