Can I Lubricate A Fluid Dynamic Bearing Fan?

[MrBananington]

I've got an Aerocool DS 140mm fan with fluid dynamic bearings. I'm attempting to lubricate the bearing, bu when I took the sticker off there wasn't any cap to remove. Is it a sealed system or something?

I uploaded a picture of the fan showing that it doesn't seem to have a cap.

Yeah fluid bearings are sealed

Crap. Thanks for the info.
