Are you frustrated by how loud your fan is? The average room fan can produce a noise level of around 50 decibels which can really start to grate on you after a while, especially if you’re trying to sleep. Yes, they’re good at keeping you cool but it shouldn’t be at your expense of peace of mind.

So if you’re annoyed by the noise your room fan makes know that you don’t have to live with it. In this post, we’re going to cover 9 tips on how to make a fan quieter to help you get some quiet.

1. Ensure the Fan is on a Flat, Level Surface

It sounds obvious but the first thing to check is that your fan is on a flat, level surface.

This will not only ensure that you get balanced airflow but it will, more importantly, reduce the risk of wobbling which can cause noise as the blades spin and vibrate on whatever surface you have it on.

If your fan has feet to stand on or adjustable screws then use them to level out the base.

2. Use the Slowest Setting Possible

Most room fans have different speed settings you can choose from: low medium and high.

Obviously, you want to select the lowest setting possible as with most fans, the slower they go, the less noise they produce so it’s worth sacrificing some cooling in exchange for a bit more silence…

You should also turn off the oscillating feature if you have it on. The more moving parts your fan has the louder it will be so simply turning off the rotation function on the fan can actually make the fan quieter.

3. Place it on a Rug or Carpet

The worst thing you can do is to place your fan on a hard, tiled, or wooden floor. These types of surfaces will amplify the sound produced by the fan blades and it’ll make everything louder.

To help prevent this, always place your fan on a rug or carpet as this will absorb a lot of the vibrations and reduce the noise levels.

The thicker the rug the better and even a blanket can work if you don’t have carpets or thick rugs.

4. Keep it Clean and Free of Dust

Our next tip is to give your fan a clean. No one likes cleaning so we understand if you want to sweep this task under the rug but when the fan is on it will generate heat which in turn will accumulate dust on the blades and around the fan motor.

It’s important to clean the blades regularly and wipe down the motor and grille every few months. Doing so will ensure that your fan stays in good condition, will last for longer, and also reduces noise by keeping dust away from the moving parts.

To clean it get a dry cloth and gently wipe down the motor and grille. You can also use a vacuum cleaner with a brush attachment to get rid of stubborn dust.

5. Check the Screws are Tight

Next, check that there aren’t any loose screws and that the bolts are all tight and secure.

Loose screws can cause vibrations or rattling which not only produces noise but it could be dangerous too as the fan may fall off whatever surface you have it on and onto someone or something below.

So, grab your screwdriver and make sure that there aren’t any loose parts and everything is nice and tight to maintain a safe, quiet environment.

6. Align the Fan’s Blades

Another thing you’ll want to look at to make your fan quieter is to check the fan blades are properly aligned. If they’re not, this can cause it to wobble or vibrate which will make it louder than normal.

Fortunately, in most cases, the blades are simple to realign by loosening the screws and then gently moving them into position. Once you’ve done so securely tighten the screws again and your fan should be much quieter.

Occasionally though, a blade might become completely misshapen due to being banged around or knocked over so if you notice anything odd like this then you’ll need to replace the blade as soon as possible otherwise it could snap off at some point.

We recommend that you align the blades with the airflow so that it allows for a smooth and even airflow. If you’ve got an adjustable fan then this is easy to do but if not, try rotating the fan around until you find your most comfortable setting.

7. Oil the Fan’s Motor

Depending on what type of fan you have and how handy you are, you may want to consider giving it a bit of oil.

If your fan has ball bearings, they need to be lubricated occasionally otherwise they’ll wear out faster and it may reduce the lifespan of your fan significantly. So get your oil canister or spray on some WD40 and give them a top-up…

Lubricating them in this way will often make things run quieter as there is less friction between moving parts which can reduce noise levels.

8. Buy a Quieter Fan

And lastly, if you’ve tried all the above tips and it’s still making too much noise, then it’s probably time to swap out your noisy fan for something quieter.

Fan’s aren’t made to last forever and while it might have started off quiet, most fans get louder as they age.

New fan technology means that modern fans can be extremely quiet with some only producing noise levels of 30 decibels or less.

If you’re looking for something really quiet and want to upgrade to a new one check out the Honeywell QuietSet Tower Fan which is well worth the money and not even that expensive.

Common Causes of a Loud Room Fan

The reasons behind a noisy fan can vary, but they most likely have to do with wear and tear.

As time goes by, fans typically become louder and may produce unpleasant vibrations from internal parts that are not aligned properly or in need of repair.

Dust buildup along the fan blades may cause noise as well, requiring you to pull out a feather duster once in a while and keep things clean for a more quiet environment.

Airflow is another issue that could affect how loud your fan runs, especially if it’s leaning precariously or wobbling severely on uneven surfaces.

If the airflow is restricted because of surrounding objects such as furniture or walls, then consider removing obstructions and see if that makes a difference in making it quieter.

Summing up

As you can see, there are lots of ways to reduce the noise levels from your fan so you’ll be able to get some peace. The best thing you can do is take a look at what’s actually causing the problem in the first place, then fix it.

If none of these tips work for you then grab a new one with good reviews from previous customers who’ve commented on how quiet is.
