But, don’t let fan noises or the heat get you down too quickly because we’re going to teach you how to make a fan quieter so you can focus or hear clearly without the nuisance of your room fan!

Why Is My Room Fan So Noisy?

Fans come in a huge variety of designs, shapes, and sizes, but they all typically consist of the same basic parts. All of these cooling devices have rotating blades detached from a motor that’s encased in some type of blade guard.

There are quite a few things that could be causing your fan’s loud noises. Here’s a quick look at the most common culprits for loud fan noises!

Dents or Bends

Your fan or fan blade shape could have somehow changed when it was accidentally toppled over or the blades might have started leaning downward due to the gravitational pull. These shape changes could be affecting the smooth rotation and put extra strain on the motor.

Loose Parts

Fans emit quite a bit of vibration when they’re on. These vibrations can loosen up some of the parts inside the fan and might be causing a rattling noise as the blades continue to spin.

Dry Parts

The motor and other moving parts need to be greased from time to time in order to keep them in good condition. If the grease dries out, the components could start to rub against each other and cause loud noises!

Balance Is Off

If there’s lint on the blades, it could be disrupting the balance or start hitting the cage when it spins.

The fan could also be positioned on uneven ground which might be causing it to wobble.

Before you get to work on fixing your fan, you should take a close look at it while it’s on. Try to look for the above-mentioned issues and listen carefully for where the noises might be coming from!

How to Make a Fan Quieter

There are quite a few things you can do to make a fan quieter or to fix the issue that might be causing loud noise levels. Here’s a quick look at the top ways to reduce fan noise!

Place the Fan on a Level Surface

The fan will produce rattling sounds if it isn’t completely level. If it wobbles when the blades spin, then you should place it on a flat surface. It can also help if you position the fan on an anti-vibration mat, like a rubber or foam mat, that can absorb some of the vibrations and reduce the loud fan noise.

Clean the Fan

Dust, dirt, and fabric fibers can easily get stuck in the rotating components of your fan. These deposits can make it hard for the fan to rotate properly and can make the motor sound a lot louder.

The best way to reduce loud fan motor sounds is by giving the fan a good clean. Start by unplugging the fan! Next, unscrew the grill case that contains the fan blades. Now get a clean piece of cloth that you can discard after use. Hold onto the blades with one hand and use the other hand to pass a damp cloth over the sides of the blade. 

Follow with a dry cloth to dry all the components. You should also clear out the fan grills. Keep washing and rubbing it until all the dirt has been cleaned.

Tighten Loose Components

Rattling sounds are usually a sign that there might be a couple of loose screws and components within the fan. While you’re cleaning the fan, you should grab a screwdriver or wrench. Now check all screws and bolts and tighten them up firmly. 

Remember to also secure the fan grill securely. If tightening the bolts and nuts doesn’t help, then you can try and secure some of the components with some duct tape. 

Grease the Fan

The moving parts of your fan should be lubricated every six months so that all the components are able to move smoothly without putting more strain on these parts. It’s usually recommended to use a silicone lubricant on electric fan motors because these lubricants don’t become too greasy or sticky over time.

Invest in a quality silicone lubricant and oil the fan motor as well as all the other moving parts in the fan. Greasing your fan should eliminate any annoying scratching sounds and protect the rotating components of your device.

Align the Fan Blades

Fan blades can become warped after rotating for thousands of hours at incredible speeds. When this happens, the fan will start to wobble and vibrate a lot more against the floor. Misaligned blades also put a lot more strain on the motor and can make your fan motor run a lot louder.

To see if the fan blades are aligned, you can take out the blade hub and place it on the table. If you see a difference in blade height then the blades need realignment.

Now you need to align the fan blades by bending the blades that are sticking out back into position.

Replace the Cushion

Fans usually have padding in the blade hub to separate the blade from the motor. This cushion can become worn out and the components can start to scratch against the motor and produce loud sounds.

If you notice that the foam or felt cushion of the blade is all worn out then you should get a new one. The fan cushion is pretty easy to replace and can eliminate many of the loud noises that you might be hearing!
