what is ur goal doing water cooling? low temps, higher overclocks or silence? i would guess silence after reading you had 60c load temps, however not sure.
pick proper case if you are going water cooling, thats FIRST. second, never ever put rads in case and then mount fans to push air into case through those rads, you can get away with this if you do dual lube and have rad dedicated to CPU only, in gaming it wont produce almost no heat to impact ur second lube with gpu's or temps inside of a case. and in other workloads i doubt it matter if it rises a bit of C on gpu's that are on idle. i have done water cooling build cpu and gpu together in same lube, and i dislike cpu temps, im about to change that. ppl want small cases and optimal temps while water cooling thats hard. also 60c on water, thats very very high but thats my opinion.
