I originally posted this in water cooling but I think you guys might be more helpful.
I have a build I am slowly getting together and I have installed a EKWB 280MM radiator. The loop includes the i7-6950x processor and the Nvidia Titan Xp graphics card. Both blocks are EKWB. Do I have enough cooling capacity? Oh by the way this is my first time posting on this particular board and also my first custom loop.
