If you are someone that spends most of your time around the computer and all its equipment (like me), you must know how loud and annoying the noise coming from the computer equipment can be. Not only are they irritating, but they are also a distraction making very hard to concentrate and can reduce productivity.

You must be wondering to yourself where all this noise is coming from.

Well, there are multiple possibilities. The first and most obvious one is the cooling fan. However, the cooling fan plays an important role because it helps to prevent the servers from overheating and the second possibility is the walls of your server room. If the walls are too thin, then the sound will spread to other rooms, which is why the thicker the walls, the better.

Another thing you might be wondering is what’s the best way to reduce server noise. Well, there are several methods you can follow to get the job done. Some methods tend to cost more than others, so your budget will determine how well you will be able to minimize the noise.

How to Soundproof a Server Rack

After doing hours of research, here is everything I have found to be effective when it comes to soundproofing a server rack.

1. Use an Enclosed Soundproof Server Rack

One of the best ways to soundproof a server rack is to use an enclosed server rack. These are specifically designed to house a server. However, you must be careful when choosing an enclosed server rack or server cabinet because buying one that’s made of low-quality materials like thin metal or any racks that have too many gaps in them will serve you no good.

The right choice would be to invest in one that is made of thick and solid material and has only a few amounts of gaps. It’s also important that they have their own fans.

This high quality enclosed server rack from Amazon is the perfect example of what a solid soundproof cabinet should look like. If you are on a tight budget this product may be a bit pricey for you due to its massive size. There are many different sizes on the market to choose from. Otherwise from the size, the main thing you should pay close attention to is the ventilation, you want the server rack to have enough ventilation, but not too much.

2. Mass Loaded Vinyl

Mass loaded vinyl is one of the most popular and effective soundproofing materials on the market for many years to help with sound isolation. Installing it around your server rack will help to eliminate vibration noise that is caused by your servers or fans.

The installation process is quite easy. All you need to do is simply cut the material to the specific size and lay the vinyl on top of the rack and then place your servers back on top. You can also use glue or any other adhesive to help keep the material in place. If you are interested then click here to check the current pricing on Amazon.

3. Sound Deadening Mats

These mats come in different forms for various purposes. They are a variation of MLV and were developed as sound deadening mats especially for cars, studios or homes because of their superb sound deadening abilities.

These mats can also be used on the floors of the racks, you can either glue it to the walls or back of the cabinet, it’s up to you to choose. By using sound deadening mat you will notice a significant difference in noise.

4. Rubberized Undercoating

This is a great choice. It’s easy to use a protective coating that does not run when applied. It provides anti-corrosive protection, sounds deadening and insulation to cars, trucks and on many other surfaces. Rubberized undercoating only serves two purposes; it adds mass to dampen sound and it helps to protect from rust. This is an excellent option for metal racks.

Before using this spray you must first prepare for the unpleasant smell and delay of dry time which means you will be unable to use the cabinet for a few days. Another thing that you should keep in mind is that using this soundproof option attracts a lot of heat, but as we mentioned earlier, a soundproof cabinet will require cooling fans to quell the heat.

5. Clean Your Cooling Fans

One of the biggest problems with fans is that they tend to collect a lot of dust if they are not clean on a regular basis. The dust and debris will cause the fan to slow down and then they even get louder.

The dust will automatically cause your server to overheat, which will result in more noise over time. So what you will need to do is check your fans at least twice a month to make sure they are all clean and working properly.

If your fans are not running correctly, which will result in your servers been overheat, the outcome will certainly not be good.

6. Invest in a Quieter Fan

If you take the time out and clean your fans, but they still keep making some irritating noise, then the best option would be to invest in some quieter fans.

If you are on a tight budget you don’t have to worry because new fans are really not as expensive as you probably expect them to be.

For example, you can check this high-quality fan out on Amazon that is much quieter and a lot more efficient. The overall performance is of a much higher level. The positive reviews from users prove that despite being cheap, it still works magic, improve the airflow and reduces the noise.

Before making the purchase make sure to check if the fan is the right size for your particular server.

7. Replace the Old Server With a New Quieter One

You should keep in mind that technology is always changing. Electronics are always getting more advanced and the same goes for the server. If you have an old server that’s not functioning properly then the only choice you have is to replace it with a new one that doesn’t make any sort of unwanted noise. The newer server tends to be faster, quiet and a lot more efficient than the older ones.

Even though am not an expert when it comes to the server, I’ve done a great amount of researching and I have managed to find a perfect server for you.

This Dell PowerEdge T30 Tower Server System is a very popular pick and for a good reason. It’s small, compact and has modern technology. There are lots of positive user reviews that stated that they are satisfied with how well this server performs.

It is also very versatile and affordable in comparison to most of the other servers on the market. If you have a small lot of servers, then purchasing a new server may be the best option.


These are the ultimate steps you must follow in order to make your server rack silent once and for all. Has you can see all these methods are pretty easy to implement, however, if you are on a budget then the most affordable option would be to replace all of the fans with quieter ones. Changing out the fans will help to reduce unwanted noises from vibrations and squeaking from old fans.

If money is not an issue for you, then what is recommend doing is to replace all your equipment with new servers. This is probably the most effective option.
