another tip when fitting the Tuniq, undo the 4 small phillips screws on top of the cooler, they're the ones that lock the 120CM fan in place, pull the fan up out of the cooler by approx 3" and use anything to wedge it in that raised position (i use the handle of the screwdriver) your fingers now have more room to manouver when screwing down those brass thumbscrews, when you're done remove the screwdriver push the fan back down and lock in place withe the 4 phillips screws.
