Thank you for feedback guys. I will be buying 360 Aquacomputer radiator. Below is my current rig with gtx980 and 240 rad btw.

Here is what I know: a typical 2 section radiator wont be enough to do that. I know because I tried. Water gets dangerously hot. My problem is I don't know if this brand can do it better, can it? Please, if you use this brand radiator tell me about your rig and your temps and what size you have and what are you cooling. CPU, CPU plus GPU, GPU alone. I could use any help now.
