What size rad for 2600k + gtx 780

[ultimakrel]

always wanted to do a custom water loop and finances permitting after the new year im fancying taking the plunge, I have a HAF X case with a 2600k at 4.5ghz (currently on auto vcore but thats another story thanks to my motherboard) under a noctua nh-d14 and a gtx 780 that i want to include on the same loop. temps are really quite fine im doing it simply for the aesthetics. possibly may add a 2nd 780 down the line so would a 360mm rad be enough or with some modding would the HAF X hold a 420mm rad? any help is greatly appreciated

Youd want a 360mm 60mm thick rad for that fella and still be able to run the fans quiet

Cheers dude, yeah ill defo be aiming to keep it fairly quiet. I share yr sentiments on keeping noise levels to a minimum whilst managing temps. mind the nh-d14 keeps it pretty cool and is nice and quiet. after being very impressed with that cooler I want to use noctua fans on the rad but as shallow as it is the beige and brown will spoil the look of my system haha
