Word of warning: If you buy one of these, I'd put some motherboard washers around the little posts that stick up through the motherboard. (not inc.) I did not, found (like others) the hoses are stiff and I screwed into the motherboard itself. P6T/i7 965 burned due to scored traces shorting. There are plastic housings around the screws which obscure your view of what you're screwing into, and there is nothing in their mounting pack to protect your motherboard if you're not perfectly on target to the posts. At this point, I prefer the Corsair H5O in my other rig, but would prefer the ECO with safer mounting brackets as it expels air rather than drawing it in.
