um... i'm not getting your question. that's a cpu water block, generally you need more parts then that... a radiator, pump, tubing, reservoir... that antec fan is part of an open benching case... i suspect it blows down on the mb, not up, so you'd be blowing hot air down on your mb, when the whole point of such a rig is to cool the mb parts... not heat them up. furthermore large fans rarely have good static pressure, which means they move air poorly through a radiator, you'd likely be much better off sticking some fans on the rad and set the rad up pointing away and perpendicular to the benching fan so it doesn't interfere with it's airflow..
