How To Fix A Noisy Computer Fan

Read Time:5 Minute, 58 Second

There are a few things you can do if your computer is making a lot of noise. The first thing you should check is that you have a new fan. If the noise is coming from the same place as the noise when you’re installing a new fan, it’s probably not the fan. Although it’s possible that you’ve installed the fan incorrectly and that’s why it’s making the noise. If you’ve installed the fan correctly and the noise is still coming from the same place as the new fan, then you have a second issue. The first thing you should do is find a way to turn the noise off. Some of the noises you might hear from a computer fan are normal. If you hear a loud clicking noise when the computer is first turned on, for example.

But if the noise is getting to you, there’s a chance you can fix it. Let’s take a look at some of the most common tips for fixing a noisy computer fan.

Check your case and fans

If your computer is making a lot of noise and it’s not the case, fans, or power supply, then check your case and fans. If either of these components is making too much noise, replace it. Luckily, most mid-tower cases have easy access opening on the top or sides to make replacing your fans a breeze. Just make sure you check the manufacturer’s guide to make sure you’re replacing the right fans. If your power supply is making too much noise, your power-supply based fan, or your power supply, might be the culprit. Make sure your PSU’s fan is spinning, and if that’s not the case, then you probably just need a new power supply.

Check your power supply

Your power supply is often one of the first things to go bad on a computer. So if your computer is keeping its other parts cool but making a lot of noise, it’s a good sign that your power supply might be at fault.

Before you go out and buy a new power supply for your computer, though, first make sure you’re not just trying to do too much with it. If your computer is struggling to run a few of your most common applications, like email and streaming video, you may be trying to do too much with it. Also, check your power settings. If you’re running your computer at full speed constantly, it’s going to make a lot of noise. Even if it’s just a little bit of noise every second, it’s still adding up.

Make sure your case has good airflow

One of the easiest ways to fix a noisy computer is to make sure your case has good airflow. Take a peek inside your computer. You want to make sure there’s plenty of room for your components to breathe. Fans can add to a lot of the noise a computer makes, and if your case is too tight, they can’t do their job. You may be able to save your computer some noise by opening your case up a bit.

Even if you can’t open your case, you can still get better airflow by picking a different case and/or fan.

Check your RAM and power supply

If your computer is making a lot of noise and it’s not the fans, case, or power supply, then check your RAM and power supply.

Your RAM is one of the most common causes of a noisy computer, and it’s especially common when installing new RAM. Your computer will often have to run much slower as it bootstraps when you install new RAM, and that noise can be hard to hear over a loud computer fan.

If your computer is making a lot of noise and your power supply is still working, it’s a good sign that you probably have a power supply issue.

Make sure you have a new fan

If you’re sure you’ve checked everything else in this guide and your computer is still making a lot of noise, then you might have a fan issue.

Computer fans are meant to be loud, so if you’ve got a quieter fan, it’s likely louder than your current fan. If your computer is making a lot of noise, it’s a good sign that your current fan is probably not strong enough to keep everything cool.

Fix the noise with a software update or fan swap

Sometimes, the only way to fix a noisy computer fan is with a software update or fan swap.

A software update is an update to your operating system that could be causing your computer to make noise. If you don’t want to risk it or you don’t have enough time, patience, or skill to do it yourself, you can find someone who will do it for you.

If you’re not comfortable doing it yourself, you’re probably better off replacing the fan yourself. No matter which option you pick, you’ll want to make sure you’re replacing the right fan. There’s a fan for almost every computer component, and some fans are designed to spin faster than others. If you’re not sure which fan is right for your computer, check your manufacturer’s guide.

Other Tips

Clean your computer – Every once in a while, it’s a good idea to give your computer a nice cleaning. This will help keep any dust and debris from building up, which can make your computer make a lot of noise. A good cleaning can help you avoid a noisy computer.
Be sure to open your case – One of the easiest ways to get better airflow and make sure your fans are getting enough space to work is to open your case.
Dust your computer – Another common cause of a noisy computer is dust on your components. If you want to prevent dust from getting onto your components from building up inside your computer, you need to make sure to dust your computer regularly.
Keep your computer clean – To make sure your computer stays clean, it’s a good idea to open up your case every once in a while and give your computer a good cleaning.
Conclusion

Sometimes, no matter what you do, your computer will make a lot of noise. It could be because the fans are dirty or because your power supply is too small.

If your computer fan is overly loud, you’ll want to check all of the things above to make sure your computer is getting enough airflow, that the case is well-ventilated, and that your fans aren’t blocked by dust or debris.

If none of these things is the problem, there are a few different things you can try to make your computer run quieter. One is updating your computer’s drivers, and the other thing you can try is taking your computer apart and cleaning or replacing your fan.
