Reducing Fan Noise using Lubricant

[artemis0007]

Hi all!
I just read an old article on tweak3d which said that you could use some sort of lube to quiet down a noisy fan.

I was curious if anybody tried this out, and if so did it help?

I had something posted on that well over a year ago ;)

and yes it does work.

I did that to all my fans, just poured some sewing machine oil into the bearing.

Brad you gotta reconize what that green goop is that I used, you work at an R/C shop :)

[Brad]

hehe, of course. Tamiya have their own name for it, which I can't remember right now. I do have a couple of tubes of it somewhere around here

How much does it quieten things down? My 172 makes a fair bit of bearing noise (being huge and all)I might lube it up a bit. Incidentally I have stripped it down previously and can get to the bearings themselves, would this be a better bet or not worth the effort? (it's a PITA to reassamble).

[Brad]

just pour a whole pile of oil into the fan, see what it does to it's noise. if it doesn't drop it too much, then I'd look into playing with pulling it apart

[Butcher]

Hmm need to get some oil I think :)

[Brad]

on my sunon's at low speed I could hear the motors quite a bit, now I can just hear wind noise

with a fan there are usually 2 bearing disks... how do you oil the one that is farther in there without takin everything apart?

[Brad]

no idea, unless the oil goes all the way through to the second bearing
