This means that ?
You'll want to calculate your total loop TDP and then choose components that will suit your heat load needs.
You are looking at the neighborhood of 450 watts total in that loop (with CPU+GPU). Most average 360 rads will dissipate 500-600 watts or so with 1500 rpm fans, so this would be a good place to start, or something similar, like a 240+120. Even some good 240 rads will reach this, like the XPSC RX and EX series, Magicool's thick 240 as well as others.
