H20 Cooling Config Questions

[cureboy]

I'm thinking about building my own liquid cooling rig, and was wondering if people could give some insight.

My system is a Duron850@7.5x133Mhz@1.75V on an Abit KT7A-RAID board. For the HSF I have a Thermaltake VolcanoII. With the stock fans on the HSF, the northbridge, the Radeon, and the three 80mm ones in my case (a Lian Li PC-60) the CPU temp is in the 27-29°C range, and at the absolute worst is 48°C (ambient case temp is 22-26°C). I've got a mid-speed Delta fan (not the leafblower) which I'm guessing should push those down another 5-10&degC.

So, water-cooling is on the table, especially as summer apporaches. Realistically, I only truly need to worrk about the CPU, as it's the only thing I'm overclocking, but ideally I'd like to cool the Radeon and Northbridge with watercooling as well. Some setups I've been thinking about:

Config 1:
2 closed cooling systems

a: Pump#1 - CPU - Radiator#1

b: Pump#2 - Northbridge - Radeon - Radiator#2


Config 2:
1 closed system all inline

Pump - Northbridge - Radeon - CPU - Radiator

Config 3:
1 closed system w/ forking

Pump -(fork1:CPU, fork2:Northbridge and Radeon) - Radiator

Config 1 would use two small radiators, 2 and 3 would use 1 bigger one. I think right behind the two front fans in my case are the logical place for that. I've seen all the parts I'd need online, except for one sized for the Northbridge.. anyone seen one?

I think that due to the lack of room in the case of a PC, the best way to go would be one larger radiator with a distribution block for the hoses.

I second that, you get the best, most consistent cooling with the least amount of space...

Ok, so I presume a "distribution block" is a glorified splitter? Or is there more complicated plumbing involved?
