So after doing a lazy amount of research, I elected to keep the fan.
The Diamond logo with some fan stats were on one side, but the true model was on the sticker on the back.

They also made the fan that was in the AT power supply I recently recapped. I saw that it said Hypro bearing. AddA actually has some reading for it. http://www.adda.com.tw/tech.php?no=7
I know that some fans have caps over the bearing. This one did not. It basically used the rear sticker to cover to bearing.

I cleaned the dust from the fan and the heatsink. Then I added 3-In-One oil that I picked up at the grocery store and closed up.

Naturally, the sticker isn't quite as sticky as it was! I waited a bit to put it back on the heatsink - I wiped down the edges of the sticker, turned the fan over, made sure it wasn't leaving any oil residue, etc. After it seemed like I got the excess oil cleaned up, I place the fan back on the heatsink and tightened it down.
Two notes regarding the "sticker over the oil" -
1: I peeled the sticker away at the top of the fan assembly (where the wires come out) so any sticker that is peeling away is at the top of the heatsink/card. Good for system use as it will either be at the top when upright (desktop case) or upside down with sticker facing straight up (tower case).
2: More importantly, the back of the fan/back sticker is firmly clamped to the heatsink with the 4-screw bracket that held it in place. There was no dust between the back of the fan and the inside of the heatsink because there was basically no space between the two (see dust pattern inside heatsink in the second photo above). The clamp should therefore keep the sticker sealed.
Ideally, I suppose a new sticker (or even better - a cap) would do best on the back rather than reusing a peeled sticker. Funny - I actually did a bit of reading after I did the oil work using the search term "hypro bearing oil cap," and what do you know but this came up - http://www.dansdata.com/fanmaint.htm
I may experiment with the Banshee on the bench a bit prior to integrating it into one of my systems, but the darn thing is super quiet now.
