Safe lubricants for GPU fans?

[AshkanVafaee]

Hi. One of my gpu fans is spinning significantly slower than the other. I'ver heard that I can lubricate this fan to make it run smooth again. Which lubricant should I use/is safe to use? I know vegetable oil is safe as it is not electrically conductive but I was wondering about motor oil and petroleum jelly.

Thanks

i'd use powered graphite in the bearing, maybe add some oil to help it coat the bearing better. (like what a watch smith uses)

WD-40 isn't recommended as its a water displacement soultion. (it will work but once it drys out your back to square one)

any light machine oil will work just fine.vegetable oil will gum up and get sticky so i wouldnt use it.
