i'm currently planning to invest in dual sli for the MSI gtx 970's and i'd like to overclock them. now the problem is i don't really know how to water cool them both. well i know i need an sli bridge but what else do i need? i've seen some sort of devices you put on top and put your tubing through it but i'm very nervous of getting a wrong type of waterblock/water cooling sli thing
