The primary items interacting with the air flow is the blades of the fan. Therefore to create more white noise, I suggest roughing up the surface of the blades so that it creates more turbulence. The front edge of the blades is what hits the air first while the face of the blade is in contact with the air much longer.
What makes a fan noisy?
The principal causes of fan noise are airstream turbulence and mechanical components connected to the fan. The term fan noise describes a type of unwanted sound produced by the fan or its components which may require corrective action to bring the fan sound to an acceptable level.
Why do table fans make noise?
If your table fan is noisy, then it could be the dust particles that have accumulated in the parts of the fan. This a common problem that arises due to continuous usage of table fans. Cleaning your fan is a simple solution to the problem.
Why is my table fan slow?
The torque to drive the motor of your electric fan comes from the magnetic field induced in the motor coils when electricity passes through the coils. When the fan slows down and stops, it could simply be because the coils are worn out, but it’s often a burned-out capacitor.
Where do you put oil in an electric fan?

Do more blades make a fan quieter?
Fans with more blades are known to be quieter than those with fewer blades. Further, fans with more blades tend to be better balanced and less ambient noise.
Are metal fans quieter?
4. Select a fan with large, metal blades. The metal blades are slightly louder than plastic blades, but they are capable of moving more air. Typically, more blades move more air.
How do you lubricate a table fan?
- Remove the front grill of the fan. …
- Lay the fan down on a flat surface with the exposed face up. …
- Apply a light nondetergent household oil that is SAE20. …
- Spray the shaft carefully with lightweight lubricant. …
- Reassemble the fan and test.
- Remove the front blade guard by prying off the clips or removing the screws.
Can I use cooking oil in electric fan?
Cooking oil will “gum up” after a while and the fans will literally stop spinning. Machine oil is better, but even then, it can catch dust and ultimately increase friction. Your best solution is simply to replace the fan, if it is noisy.
Can I use WD-40 on electric fan?
Apparently WD-40 was the wrong oil to use. [Never put WD-40 in] any electric motor, even if the rotor is stuck from filthy dried-up lubricant! It not only removes any remaining lube, but it can melt coil wires (the lightly-coated copper wires twisted up in electric motors) and cause an electrical short.
What can I use to lubricate a fan?
Use 10- 15- or 20-weight non-detergent motor oil to lubricate your fan. It’s important to avoid detergent, which can gum up the bearings. Don’t rely on penetrating oils, such as 3-in-1 oil. They are fine for loosening stuck screws but aren’t heavy enough to lubricate a fan.
Can you oil a fan?
To oil a ceiling fan, use a non-detergent, electric motor oil, which is safe to use with an electric motor. Before you add the oil, clean off the fan and oil hole using an all-purpose cleaner. Then, slowly pour 1-2 ounces of oil into the oil hole.
