What causes a fan, most often the one on top of a stove to be so loud when turned on?
I mean is it the air moving or the motor?

crx said:Because of the water vapors (humidity) that makes the air more dense ,and creates more turbulence around the blades... . .)
sophiecentaur said:In fact, humid air is less dense than air with no water molecules. The molecular mass of H2O is less than that of O2 and N2 and there are the same number of molecules (total) per unit volume at any given pressure. This is a popular misconception - along with "Air is like a sponge".
you are completely right but i think that water will saturate the air rather than diffuse at a molecular level (above a stove for example or in the bathroom) and will form microscopic droplets of millions of molecules which at that level will have a higher density than dry air.
And the oil / fat molecules which are very much more massive and which soon will coat the blades and increase drag and turbulence.sophiecentaur said:crx
You have a point about the droplets.

There are several reasons why an oven fan can be noisy. One possible reason is that the fan may be dirty or clogged with debris, which can cause it to work harder and produce more noise. Another possible reason is that the fan blades may be damaged or misaligned, which can also lead to increased noise. Additionally, as ovens age, their fans may become louder due to wear and tear.
No, not all oven fans are noisy. The noise level of an oven fan can vary depending on the model and brand of the oven. Some newer models have quieter fans due to advances in technology and design. However, it is normal for an oven fan to produce some level of noise while in use.
Yes, there are a few steps you can take to make your oven fan quieter. First, make sure the fan and its components are clean and free of debris. If the fan blades are misaligned or damaged, you may need to have them repaired or replaced. Additionally, you can try placing sound-absorbing materials such as rubber pads or insulation around the fan to reduce noise.
In most cases, the noise from an oven fan is not harmful. However, if the noise level is excessive, it can be a sign of a larger issue with the fan or oven. It is important to address any unusual or loud noises coming from your oven to prevent potential damage to the appliance.
It is not recommended to use your oven if the fan is noisy. The noise could be an indication of a problem with the fan or other components of the oven, which could potentially lead to further damage. If your oven fan is unusually loud, it is best to have it inspected and repaired before using the oven again.
