I would keep the rads in series and put your second rad between two components. For example for your setup this would probably be best:
pump -> rad1 -> CPU -> rad2 -> GFX -> NB -> pump

My case is a mid-tower, so it's quite small for all this extra stuff, and doesn't have a lot of room to bend.
The order does not matter and it does not work like you are describing above. The water temp does not change quickly due to its large thermal capacity and it certainly doesn't bounce up and down 5-10C as it goes around the water loop. Do you really think it changes that much in one pass through a block or radiator? The way radiators work is not intuitive but they are key to understanding how watercooling works.honhon said:that ^^ would probably be the best solution, b/c the CPU will heat the liquid then go into another cooler be cooled and then get some more heat and then go into a cooler again.
very good idea if i do say so myself.

What actually happens is the water and cpu temps slowly rise as the blocks add a steady amount of heat to the circulating water. As the water temp rises, the radiator starts to dissipate heat more effectively. The water temp will continue to rise until equalibrium occurs between the heat added by the blocks and heat dissipated in the rad. The heat dissipated by a rad is controlled mainly by the temperature delta between the air temp and water temp.
A given rad can dissipate much more heat IF you allow the delta between the air and water temps to rise. Increased airflow may be required for the higher heat dissipation.
The cpu temp is determined by the temp of the water in the loop plus the C/W rating of the water block multiplied by the CPU power dissipation.
Less than 1C water temp delta around the loop.lowfat said:very interesting. So lets say i put a temperature probe in the water just after the cpu, and right after the rad... so there wouldn't be a big difference in temps?
bmartin said:I already have a single 120 mm Black Ice rad for my A64.
I'm looking to add a chipset block and a block to my pcie 6800GT.
would adding another rad be a good idea?
or what should I do?
Thanks in advance for suggestions
