Note: 2 rads in series is better than one rad because of the greater exchange surface....
I'd have to disagree with this one...

2 rads in series < one rad < 2 rads in parallel

IMHO it's better to have a good high-flow rad and make the WB as efficient as possible, most any semi-decent rad will have no problem dissipating 100W of heat that a CPU puts out. But putting 2 rads in series cuts your overall flow-rate through the system down considerably. In my experience, it's not the block, but the rad that is the most restrictive to water-flow (not counting tiny chipset/GPU blocks, some of those are way too small)

Then again, my rad is a BI Prime - so I might be biased in my judgement of where the flow-restriction is in a system after looking at billa's graph there.
