Ok so i have had a TT Big Water Kit for some time now and i love it. It keeps my slightly overclocked system and 2 vid cards very cool and most importantly very quiet. Im thinking about putting this kit into a new system im building and upgrading my own system. Now the question i have is is the a significant gain in performance from a 3/8-1/2 ID tubing to 1/4 ID tubing and if running the larger tubing makes it louder bc of the larger pump needed. I really like the 1/4 tubing and i like compression fiitngs so i was thinking of goin the aqua computer innovatek route but i was wondering if i would be better of spending the same or even less maybe on going w/ DD or swiftech. I just don't want a loud computer and didn't know iff th DD5 pump was super lou or not and would ruin my quiet computer. Thanks for the help in advance.
