from friction on the leading edge of the blades
To troubleshoot a spinning ceiling fan making a loud noise, first check for loose screws or blades. Tighten any loose parts. If the noise persists, check for dust or debris on the blades and clean them. If the problem continues, the motor may be faulty and may need to be replaced.
Inspect it carefully, in fine detail. Make sure that all mating parts are tightly joined, and there are no loose screws. Then make sure that it is perfectly centered, and that the prop blades are not higher on one side than they are when they reach the other side. The center axis of the fan should not try to wiggle as the blades turn.
This phenomenon is due to inertia, where the blades of the fan will continue to spin briefly after the fan is turned off until the force causing them to move is dissipated. The air resistance and momentum of the spinning blades contribute to this delayed stopping effect.
A fan spinning has energy because it is converting electrical energy from the power source into kinetic energy which is responsible for the movement of the fan blades. This kinetic energy is what generates the airflow that the fan produces.
Sounds like one of the fan blades are loose, or bent or out of balance. By saying whopping noise points to a problem with uneven air currents. Almost like a ceiling fan noise would make under these circumstances..... Tom
More blades on a fan can contribute to quieter operation, but it's not a strict rule. Generally, fans with more blades can move air more efficiently at lower speeds, which can reduce noise. However, other factors like blade shape, motor quality, and fan design also play significant roles in determining the overall noise level. Ultimately, a well-designed fan with fewer blades can be quieter than a poorly designed one with more blades.
The fan blades are most likely rubbing the sides of the heater casing. The fan could be loose, the motor bad, or the fan blades broken. There is also the chance that something (candy wrapper etc.) has been sucked into the system and is rubbing the blades.

you cant. the sound is probably either a disk spinning, or the fan running so the machine doesnt melt. if its not making noise, its probably off or broken.
To make a ceiling fan quieter, you can try tightening any loose screws or connections, balancing the fan blades, and lubricating the motor. Additionally, consider installing a noise-reducing ceiling fan blade or purchasing a new, quieter fan model.
To reduce the Samsung freezer fan noise in your refrigerator, you can try cleaning the fan blades, ensuring the refrigerator is level, and checking for any obstructions around the fan. If the noise persists, you may need to contact Samsung for further assistance.
To reduce noise from a noisy fan, you can try cleaning the fan blades, tightening any loose screws, placing rubber pads between the fan and its mounting surface, or replacing the fan with a quieter model.
