What Can Make Your PC Fan Quieter?

How to make your PC fan quieter since computers are used for countless things from leisure to work, from education to online trolling. The device has evolved incredibly since the moment it was created in its original form. Now personal computers are amongst the most commonly used electronic devices. They got smaller with all the structural components fitting into ever shrinking volumes. Fans that cool computers down sometimes make quite a lot of noise, especially if they’re functioning for quite a while. It is important to know what causes this noise and how to eliminate this problem, in case it has already emerged.

Computer fan malfunction

Loud computer/laptop fans can indicate a problem, especially if it lasts for a long time. Since they are used as the computer’s internal system thermal regulator, loud noises simply indicate that they are working harder than usual.

If this symptom is not addressed, it can have a variety of consequences, from decreased performance to blank computer screens and, in extreme cases, system crashes or endless series of reboots.

Gaming as a cause of fan over speeding

If you hear a loud buzz from inside the PC while playing games, it’s likely one (or more) of fans running too fast. Gaming demands optimal performance from all or almost all the pieces – RAM, graphics card, GPU, CPU, etc.

These elements heat a lot, and, ironically, are very sensitive and susceptible to thermal damage. Thus, to compensate for the unfolding overheating, your PC spins the fans faster. This way hot air is thrown out faster, substituted with somewhat colder air.

Sudden fan noise

Depending on the tasks you use your PC for most often, it might start making some noises. That means your hard drive or fans run at significant speed. Your hard drive might be the cause of this noise if you use water cooling. Hard drives make noise when the platters are spinning and the heads are searching for data, especially when performing intensive tasks.

Computer fan and overheating

The portability of the new generation of computers is possible because the internal components are compact and cleverly assembled for optimal smoothness. Inside your computer, there are many complex hardware components that, as mentioned above, generate a lot of heat yet can themselves get damaged by high temperatures.

That’s why the fans are so important. They reduce the temperature inside the PC, being placed right next to the key overheating elements. They do this by rotating – circulating the air inside the computer, meaning they push hot air out and let cool air in to naturally cool your PC.

Fans indeed can make noise when you’re working with large files, playing games, etc., as an extra need in cooling your PC emerges. When your PC is slowing down this effect can manifest itself as well. As long as your fans cool down after intense work, you don’t have anything to worry about. 

However, even if the noise is a normal soundtrack of a functioning PC, you should look at the possible reasons why your fans are making too much noise. Now that you know what the fan does, let’s check what are the common issues with it.

Common issues with PC fans

Physical damage

Moving parts, of course, wear out with time. So, in case the fan of your device is too loud, it could easily be due to some mechanical damage or a loose screw. It may also be caused by some bad firmware, which means that the hardware that supports the fan may be defective.

Insufficient ventilation

When your computer cannot deal with heat the fans are unable to get the hot air out and welcome the cooler air. Simply placing a laptop on your lap may cause problems – the heat will get back inside, making the cooling system’s work meaningless.

In addition, if you somehow block the vents by misplacing your PC, it will also get much hotter. Most importantly, the fan will run faster than it should to make up for the unintentional overheating.


Hair, dust, and lint can accumulate inside your PC. Once the debris stuffs one of the fans, the efficiency shall go down. Since the efficiency is now low, the system will make the fan speed higher to compensate for worsened cooling. Therefore, the noise can get more loud.

Processor overuse

Sometimes the cause may have nothing to do with fans. If some process exhausts available CPU resources, it can easily cause quick overheating. If your computer fan is making a loud noise for no obvious reason, it could easily be due to excessive CPU usage.

How to fix a loud computer fan and make your PC fan quieter

Preventing troubles is always better than dealing with their consequences. If it is possible, of course. So, if your PC fan is making quite a loud noise that is hard to stand, try using the following tips:

  • Put the PC in a place where vents won’t be blocked, and the flow of air is free.
  • Keep all the fans and vents clean.
  • For a laptop, use cooling pads.
  • Install software for better fan control.
  • Replace fans (if needed).
  • Close applications and processes that are unimportant.

Still, your computer fan may continue being too noisy. In that case, take it to a service center – Repairs Bay, for example, is a good option for New Yorkers. You can also contact the manufacturer.


Your computer fan can make a lot of noise, but here are some things you can do to eliminate this problem and make your PC fan quieter. Remember, high temperature and debris are the main causes of computer fans’ excessive noise. Hopefully, your questions about fan noise were answered here, so that you can continue to use your computer without any worries.
