High-speed fans are the best ways to keep the room cool by ensuring proper ventilation. These fans make the air inside the house spin and make it cool. High-speed fans are better than ACs, based on energy consumption and no use of harmful gases. A high-speed ceiling fan has become an essential part of a modern house.

A high-speed fan consists of various parts connected by multiple screws. A fan has blades that are connected with a bracket through screws. A motor that moves the fan in a circular motion stays above the bracket, covered by the canopy, and finally, a rod connects the fan with the ceiling. There can be multiple reasons for fans to produce unnecessary noise related to these parts.

Reasons a High-Speed Fan Causes Noise.

High-speed fans usually produce undesirable noises, a commonly encountered problem. The unwanted noise can cause nuisance and disturb your peaceful sleep at night. High-speed ceiling fans sometimes create noise while moving at peak speeds, which is not a big issue, but if the noise is heard at lower speeds, it can indicate major issues when it moves slowly.

The unwanted sounds are created for various reasons. Here are some possible reasons discussed below.

Dimmer Switch

Some high-speed fans use a dimmer switch to adjust the fan speed. These dimmer switches are not a convenient option for high-speed fans. Using these types of switches can create humming sounds while changing the speed.

Loose Screw

The various parts of the fan are connected with the help of some screws. If a screw is loosened or absent, it can create a lot of noise, and it may even fall out of place if not repaired on time. The loosened screw makes the fan generate a rattling sound.

Loose Canopy

The canopies cover the motor, hanging below the down rod. These are plastic cups that cover and protect the motor. If a canopy is loose, it will constantly rub against the motor or the down rod to create unsettling sounds.

Down Rod Issue

Down rods hangs the fan from the ceiling. The down rods are unique for fans and have a specific fitting. If the rods are replaced, it can cause a regular noise.


If multiple fans are connected to one circuit, the capacitor may fail to work, creating irritating noises that can disturb your sleep.

Uneven Voltage

The motor inside the fan that helps the high-speed ceiling fan move requires an optimum electricity voltage. If the voltage is lower than 105 volts A/C, it will fail to move the motor in the manner required, which might also cause noise.

Old Bearing

The bearing must be capable enough to hold the fan rotors steady. If a bearing is either old or damaged, it can create a grinding sound.

Absence of Lubrication

A fan is usually installed with lubricants that reduce friction and makes it easy to rotate. If the fan has lost its lubrication, the dust can accumulate easily, and the friction can increase noise.

How to Fix the Issue

There are many ways to prevent the sounds generated by the fan.

Use of Standard Speed Control:- The traditional dimmers are often used for lights, but those are not convenient for fans. The dimmers used by fans must be replaced with standard speed control settings for better control. It will stop the sounds caused by dimmers.

Changing Capacitor:- If a Capacitor is old or in bad condition, it can't provide power to the blades. Replacing the capacitor can reduce the noise and make your fan operate smoothly.

Tighten Screws:- Sometimes the screws that hold the entire body, including the blades of the fan together, could become loose. Tightening the screws will fix the parts together. By doing this, you can avoid the unsettling noises generated by it.

Clean & Lubricate Parts:- Proper cleaning of parts of the fan is necessary to avoid rusting and dust accumulation. If a fan is not cleaned periodically, it will create a lot of noise. Lubricating the fan reduces the friction and makes the fan smooth.

Balance the Blades:- If the blades of a fan are not placed rightly, they can generate noise and even fall apart with time. Rearranging the blades can make them stay in the place and reduce noise.

Call a Professional:- If you can't stop the noise produced by your high-speed ceiling fan yourself, it's better to call a professional mechanic to fix the issue.

Replace the Fan:- If the problem doesn't stop even after following the steps mentioned above, you may require to replace the fan.


High-speed ceiling fans must contribute to your peaceful sleep; if they start hampering it by creating unnecessary noises, it's better to solve the issues first. Follow the article and fix the irritating noises generated by your fan.
