What watercooling system? Ambient temps? Load temps are okay?
I'll steer you to some more technical links, please spend a few days (DAYS) reading posts, searching, learning. Don't forget to look for your case with WC. Google your case and the word watercool or some combination of that. WC stuff is larger than you think, I know from experience. WC setups done right are awesome and almost silent.
Great place, not wayyy over the top with uber WC guys.
