A desk fan (table fan) fell down when it was off.
Curiously, a small portion of a blade broke by itself without being hit by anything.
The loss of a small piece of plastic in the blade should result in a small loss of air flow like a degraded performance.
Unfortunately no! The size does not matter! The fan made a commotion and vibrations, wobbled and moved its own body hither and thither!
Why ?
The blade was fixed and the answer was sought from the Internet.
Thanks to these videos which motivated me to repair the fan.
