Why Is My Laptop Fan So Loud?

Chris Campbell17 Jan 2022

When it comes to getting work done in your desired setting, nothing beats a laptop. However, mobility comes with a price. Because of the confined space within and the high-capacity batteries, heat accumulation is frequently an issue. When things become hot, your laptop fan will start to suffer.

Why Is My Laptop Making a Fan Noise?

So why is your laptop fan making noise? Fans are included in laptops for one reason: to disperse heat by moving air. When your fans turn on, it's usually because they're intended to. However, it may be disturbing and, in some situations, rather loud. When under tremendous pressure, even the most costly laptop, such as the newest MacBook Pro, sounds like a helicopter taking flight.

If the temperature outside is high, your laptop will have to work more to disperse heat, resulting in increased fan noise. Likewise, if the vents are blocked, like when you're working on your bed or sofa, the laptop will become heated. Similarly, if you're running a 3D game, utilizing WebGL, or processing videos, heat will accumulate.

Why Is My Laptop Fan So Loud All of a Sudden?

You're typing away when the usual pleasant buzz of your laptop suddenly becomes louder. Then all of a sudden it escalates to a whizzing and crunching noise worse than your mower.

Heat accumulates due to the confined area within the machine and the large capacity batteries it runs on. And when things heat up, your laptop fan speeds up, resulting in noise.  The fan is the nosiest laptop component, spinning faster when there is more heat to disperse. 

Although some laptops are inherently noisier than others, the following may be the source of a sudden loud laptop:

  • Laptops overheat more as they age, particularly if you haven't cleaned your laptop vents regularly. The fans could be rotating quicker owing to dust in the system, but it might also be due to how you use the laptop.  Using your laptop on a soft surface like your bed might cause the vents to get blocked, decreasing airflow and causing the fans to spin faster.
  • You may be faced with an increased system load if you've upgraded the computer system or installed any program that runs continually in the background. When you place a strain on your system, they heat up and turn on their fans. Consider what you're doing when the fans begin to spin noisily. Games, editing, or viewing videos place greater strain on a laptop than surfing the internet.
  • It's likely that the loud noise is coming from the hard drive rather than the fans. Back up the data as soon as you notice a more audible whirling, churning, or popping sound near your hard disk. Whenever the mechanical components within an HDD fail, the effect is a louder hard disk. After backing up data, the only solution is to replace the hard disk with a new one.

Why Is My New Laptop Fan So Loud?

You've just gotten a new laptop, but something doesn't feel quite right. Although it is new, your laptop's fan is much louder than it ought to be, which is quite bothersome. These could be the reasons why your new laptop is suddenly so loud:

  • Dust and dirt can accumulate even in a new laptop, causing a loud fan.
  • When your laptop's CPU is under intense demand, your fans will spin quicker.
  • Having outdated drivers may also result in your device not performing to its full capacity; including a loud fan noise.
  • A faulty BIOS might also be to blame for extremely noisy fans. Because the fan speed is regulated and changed by your motherboard's BIOS, you must maintain it up to date.
  • A loud laptop fan can also be caused by a software issue. Heavy applications and programs, may boost CPU and GPU consumption, causing the fans to rotate faster than usual.
  • Unnecessary programs running in the background can also be the culprit. Although you may not be actively utilizing or interacting with them, they will consume some of your system's RAM and CPU.

Why Is My Laptop Fan So Loud: Mac Computer

You could have an issue if your MacBook's fan is spinning too loudly for too long and too often. Fans are an inevitable part of a laptop.  People sweat, animals pant, and computers use fans to stay cool. Unless you have the compact, fanless MacBook, your MacBook Pro or MacBook Air may sometimes activate its cooling system to keep its thermals under control.

Having the fans running at full throttle isn't always a clue that something is amiss with your Mac.  If you're using computationally intensive programs like HD video editors or high-end games, your Mac will be working hard, producing heat. When the fan sensor detects a temperature rise, it promptly activates the fans to protect the system from overheating.

But if your Mac's fan has progressed from sometimes spinning to frequently and noisily whirling, you should slow it down by:

  • Reviewing your applications and tabs.
  • Keeping vents free of debris.
  • Cleaning up your Mac.
  • Trying out your fans.
  • Resetting the System Management Controller.

How To Reduce Fan Noise on Laptop

Nothing is more aggravating than when a laptop fan makes frantic sounds as if it's about to take off. The irritating sound creates a barrier between you and your efficiency. But don't panic, there are solutions if your new laptop is too loud.

  • Regularly clean your hardware. Your laptop may, and almost certainly will, accumulate dust over time. Even if your fan is brand new, the accumulation of dust and dirt will have an impact on its performance. Take your time cleaning your hardware and removing all dirtiness.
  • End unnecessary computer tasks. It's likely that your laptop's fan is excessively noisy because you're putting it through more effort than it can handle. Slow things down and terminate any unneeded processes. If you run more processes than you need to, your CPU will become increasingly heated, affecting the performance of your fan. 
  • Purchase a laptop cooler. Laptops appear to get hotter.  While prior laptop models take more than a year to begin heating up, it appears that the new ones need a laptop cooler from the start. This approach may necessitate some additional cash from you, however, if you have no other options, you should strongly consider it.
  • Make use of fan speed software. Perhaps the solution is to use software to manage your fan speed to keep your laptop quieter at safe temperatures. Keep in mind, though, that overheating your laptop to lessen the noise is a poor idea. It is advised that you keep your fan speed at a reasonable level.

The next time you hear your laptop fan whizzing, don’t stress. You just need to figure out what’s causing the noise and then fix the problem.
