Currently in my system I have two 120mm rads (on top) and a 240mm rad(front) to cool my 4790k at 5ghz with 1.432v and my 980ti at 1520mhz with 140% power limit at 1.25v

Im considering getting a 360mm radiator and putting it in the top of my case then putting a 120 in the rear and keeping the 240 in the front.
Would that be worth it? Because currently when stressing both the gpu and cpu the temps get to 79c on the cpu after 15 minutes.

I also plan on adding another 980ti in the future but im not sure about overclocking.

My case is the Corsair 750D so I can handle a decent amount of radiator space.

Swiftech MCP655 at full speed. Its above my res but it has enough power to pull the water.

My fans are BitFenix Spectre 120mm and during the stress testing they were at 80% speed

I should also mention the my cpu has direct die cooling with Coollaboratory Liquid Pro between the die and waterblock so thermal paste is not an issue
