As with the other Titan products that I've looked at, the fit and finish was of a very high caliber, the back of this heatsink is in fact mirror bright. The fan assembly drops right into the center of the heatsink and uses 3 very tiny Phillips screw to attach directly to the fins. 3 different clips are provided and because of the tight tolerances involved much trial and error "dry" assembly is required to insure that you are using the correct clip.
