Yea that is what my question was, if it had an oil well, my xfx 5830 fan didn't, it seized long ago, since then I been using a huge 120mm x 38mm panaflo on the xfx 5830 hs.

So, I am guessing the sapphire extreme fans do have an oil well? If, so, I gotta contact my seller, see if it is still under warranty or what not, if not, Ima give er some lube. From reading, removing/unscrewing the fan from the HS eliminates the warranty, if so, how stupid.
