i am choosing between AC and DC motor. The price of DC motor fan is double of the AC motor fan.
I know the AC motor fan may be slowing down after long time due to capacitor issue, is DC motor fan will have the same issue (capacitor issue)?

Just installed Alpha Vannus Luna and I found the motor generate low noise like tik-tik-tik...
Hardly can hear from a distance. But when standing below the fan, I can hear it.

Thought want to purchase a DC fan because it is claimed to be quiet, end up i can hear this tik-tik-tik noise.
Just asking anyone who has a Alpha Vannus Luna fan or DC fan, is it normal that the motor still generating low noise when rotating? Or it is my fan problem, i need to ask for service?


See the uploaded the video. My phone hardly can record the noise until it is very close to the motor. But in actual condition, I can hear this tik-tik-tik noise when standing below.

Second question, is it normal for the rotating plate wobbling? (see the last part of video)

Actually the noise is there with the blade...i removed the blade for the purpose of recording the noise.
