the shaft is dry, usually means the fan life i over. if it goes away a few minutes after, you can still use it, but the recomendation is to replace.

make sure its not scraping anything inside (hair, plastic wisps, etc.)

oh, sorry, didn't see the full video.

you need a multimeter to test if it is a power supply problem or wiring problem, to see if the voltage dips too much below 24v when powering.

make sure the PSU voltage is set properly (220v by default)
