Zalman VF900-Cu VGA Cooler
 

Following Zalman's directions to the T, I install the uh, nipples and rubber rings onto the base. But wait a minute, which set of holes do I use for my 6600? According to the compatibility table I need to put them in either position 1, 2 or 3. Gee, thanks. In other words, try them in each position until you find one that fits.
