This motor sounds fine at higher speeds (air noise exceeds motor noise), but at lower speeds this thing used to be whisper quiet. It continues to operate well, even at low speeds, but sounds very noisy at lower speeds. I tried a couple of drops on either side of the motor shaft, but it did jack squat to the noise.
The video below was actually taken AFTER using a few drops of 3-in-1 oil and then allowing a few minutes for gravity to work on each side of the rotor shaft. I then reassembled the fan and ran it for a minute or so at low, then high, then low speeds and it still exhibits the EXACT same volume-tone noise as before - no perceptible change...
Any suggestions? I find that most of my filters fans/motors get noisy and I've never been able to figure out how to lubricate them to get rid of the noise. I had to toss an older one, because its flow rate was so low for how much current it was drawing - even with the filter removed! I tried lubricating it and it made now difference.
