View Full Version : Reducing Fan Noise using Lubricant

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.

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).

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

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?

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