CPU Tower Air Cooler Noise Levels: How to Reduce Them

When it comes to your computer, noise levels are important if you want to be able to use it while others are sleeping or trying to work in the same room as you. Fortunately, there are several solutions to keep your CPU tower air cooler noise level down, so that everyone in the house can get some peace and quiet while they sleep, study, watch television, or simply relax and listen to music on their own devices.

Here’s how you can reduce the amount of noise produced by your computer’s CPU tower air cooler.

Some of you may find it convenient to have an air cooler installed on your CPU tower because it can help lower your computer’s temperature and therefore speed up its performance. However, there is a trade-off between performance and noise, especially when it comes to air coolers.

If you are one of those people who would like their CPU tower cooler as quiet as possible, keep reading and we will tell you how you can reduce noise levels while still keeping your computer running smoothly.

We have also included some helpful tips that can be used with any type of CPU tower cooler whether it is an air or liquid-cooled unit.

If you’re building a new computer or upgrading your current one, you might have heard that noise levels are a factor in selecting your CPU cooler. But what is a good CPU cooler noise level, and how can you measure it? Here’s an explanation of exactly what dB(A) measurements mean and how they affect your buying decisions.

We’ll also explain some ways to reduce noise while still getting a great cooling performance. I’m a bit confused about all these different decibels (dB) ratings on fans…what do they really mean? Decibels, abbreviated as dB, are used to express sound pressure levels.

The lower the number, or dB rating, of a fan or CPU cooler, means it makes less noise. However, just because one CPU cooler has a lower dB rating than another doesn’t necessarily mean it will be quieter, the amount of noise created by a fan is dependent on other factors too.

For example, if two fans both have 30 dB ratings but one spins at 5,000 RPM and the other at 1,500 RPM, then obviously there will be more noise from the faster-spinning fan. In order to make sure you get a quiet CPU cooler for your needs, consider not only its dB rating but also its size and speed (RPM).

What does RPM stand for? RPM stands for revolutions per minute, which is a measurement of how fast something spins. Most fans and CPU coolers spin between 800 RPM and 2,400 RPM.

Do higher speeds create more noise? Yes. Higher speeds usually create more noise, so when comparing two fans with similar dB ratings but different speeds, keep in mind that the faster-spinning fan will probably be louder.

Is 40 dB loud for a PC?

Yes, 40 dB is loud for a PC because you start to notice noise around 35db. Anything over 40dB can be considered very loud.  For example, if you have your computer in your bedroom and are trying to sleep at night, then it would definitely be too loud.

At that point, it would probably not matter what kind of fan or air cooler you have on your CPU tower as long as it was being used in that room.

In fact, there are quite a few high-end air coolers that produce less than 40dB of noise. Some examples include Noctua NH-U14S and Phanteks PH-TC14PE. The quietest air cooler we’ve tested so far is Raijintek Tisis at only 28dB.

Is bigger CPU fans better?

Size matters when it comes to choosing a CPU cooler, but so does noise level. A larger tower cooler may provide better cooling performance than a smaller heatsink, but you may end up paying for that extra cooling power with increased noise levels.

When choosing your CPU cooler, think about how much space you have available inside your case, memory clearance, and whether or not you want to sacrifice some space for better cooling efficiency.

Why Is My CPU Tower Air Cooler Making So Much Noise?

The main reason why air coolers tend to make more noise than liquid ones is that they need a lot more airflow to function properly. Most computers make some noise, especially as they heat up and try to dissipate that heat.

This means that they require more power and fans to push through large amounts of air which ultimately creates excess noise. Most modern processors get very hot under load which can cause damage if left unchecked for too long so cooling them down quickly becomes very important.

One thing to note here is that newer CPUs often come with thermal paste pre-applied so if you are planning on upgrading your CPU tower then make sure you clean off any old paste before applying the new thermal compound. Don’t forget that there is also a liquid cooler which doesn’t make a noise like the air coolers do.

They work by using water to transfer heat away from the processor rather than air which makes them much quieter but they do cost quite a bit more money. Now that we know what causes these noises, let’s see how we can reduce them.

How to reduce CPU tower air cooler noise levels significantly.

A little noise isn’t a problem, but if you want your computer in your bedroom or living room, an excessive amount of noise can be frustrating. Thankfully, a few steps can reduce CPU tower air cooler noise levels significantly.

  1. For starters, always try putting your CPU tower into a case with plenty of room for airflow. This will ensure that air can move freely throughout your system without creating unnecessary resistance and making all sorts of racket in the process.

  2. You should also make sure that all cables are properly secured within your case so they won’t block any vents. Another way to reduce noise levels is by choosing an efficient fan model.

  3. Look for models that have high static pressure ratings (measured in mm/H2O) since they offer superior airflow at low RPMs which results in less noise overall. Of course, you could always choose a higher RPM model if silence isn’t your top priority but such models usually aren’t as reliable or durable either.

  4. Clean up your fans and heatsinks regularly: It’s important to keep dust and grime from clogging up your fans and heatsinks. Make sure you check them out at least once a month, or if you notice any strange noises coming from inside your tower.

    You can use a duster, or just some compressed air if you don’t have one on hand, just make sure you get into all of those little nooks and crannies so that nothing is able to build up in there.

  5. Sometimes if your computer starts making a racket, don’t ignore it. If something breaks down inside your tower, you can bet that it’s going to make all kinds of strange noises, and possibly damage other components within your tower if it isn’t taken care of quickly.

  6. Finally, we recommend installing acoustic foam inside your case to absorb sound waves and prevent them from bouncing around inside your PC. This can greatly reduce noise levels and improve your PC’s acoustics.


So, now you know how much noise a CPU tower air cooler makes. Whether it’s worth it or not depends on your needs and preferences. While most users won’t be bothered by extra noise, others want total silence in their working space. However, despite what you might think about its loudness, don’t discount a CPU tower air cooler as a viable option.
