HI everyone, I had a new build in mind.. i was thinking of water cooling (Never done a water cooling build before), I was going to buy the corsair 900D, 4 asus r9 290's, corsair ax1500w psu + asus rampge black & i7 4930K with 64gb's of kinston beast 2133mhz memory.. My problem is i've got no idea what i need to cool all these.. i have viewed a few builds & thought maybe doing two closed loops? with two 480mm rads & two 240mm.. So what pump,res,rads,fittings etc would i need to buy?
