The shroud w/fan simply has some edged fingers that snap onto the heatsink. I found by squeezing the shroud that it would flex out the finger enough for me to pry them off. Otherwise, use a flat blade screwdriver to pry out the fingers. My P3 was actually a Slot2 cartridge (and why its tangs didn't fit in the holes in the mobo brackters for the cartridge so I just used wire ties).
I had tried oiling mine, too, but that didn't last too long in quieting the fan. In under a month, it was noisy again and I wasn't going to keep oiling it. Hope it lasts longer for you.
