Hi I just bought a Titan XP sli & I'm starting to get concerned that I didn't think about heat, I saw a video that said you will need to water cool them, so my question is should I or will they be ok in stock coolers? Also I've never done water cooling that wasn't self contained.. I bought a nzxt Kraken X62 self contained for CPU so with the Titan XP should I think about water cooling them?:This is not my first build its my third, but this is the most powerful one. I bought the Formula iX just incase I wanted to go water, with a i7 7700k
