Thanks Budman. I actually unscrewed the fan today and was trying to clean it or make sure it was seated evenly (you can power the fan independent of the video card, I was using a shortwave radio display connection as a power source for the fan...he he), but I didn't have anything to lubricate it with on hand. Since I don't have any lying around and I'm gonna have to go out and buy it anyways, I may as well ask; what kind of oil did you use?
Thanks to every else, I'll check out the blue orb and zalman for future reference, but keeping it quiet is really the biggest priority here (and not spending money unless I have to).
