I am in the process of planning my first water cooling setup. However I thought it best to ask about my plan for the loop. My system consists of: MSI 955X platinum motherboard, Pentium D 3GHz dual core proc, Corsair XMS2-6400 2GB DDR2 Ram ATI X1800XT graphics card, ATI 9250 graphics card, So far for the cooling side of things I have: 1x Laing DDC-1 Plus with Plexi Top, 1x Alphacool NexXxoS ATI X1800XL/XT/XT PE Graphics Card Cooler, 1x Aquatube (res), 1x Aqua Cuplex Evo (cpu block), 1x Aqua Twinplex Graphics Card cooler (for 9250), 2x Aqua Twinplex Chipset (for north bridge and south bridge). 1x 120.2 rad + various connectors and 10mm OD tubing. I have 2 loops in mind, the first would be: Res, pump, cpu, x1800xt, 9250, northbridge, southbridge, rad, res. However I think that maybe the heat from the cpu and x1800 may overpower the other components. so the other loop i'm thinking of would involve another pump (probably a Laing DDC with Plexi Top) , and a 120.1 rad and would go: Res, pump 1, cpu, x1800, 120.2 res, then from the same res, pump 2, 9250, chipsets, 120.1, res. Thoughts? Is it over kill? i'm not really into overclocking although it may end up being clocked a little I just want it to be quiet (at the moment with the fans on it you can hear it downstairs and thats at low speed).
Personally, presuming its a BIX2, I'd think it'd be ok. But only with good airflow. Temps won't be that good, but the idle>load ratio will be improved, aswell as silence. Should be fine though I'd of thought. Rads can deal with far heat than people think
if you are not overclocking then it will be fine, you could probably run the 9520 and south bridge passively?? the 120.2 is a big enough rad.
