has a good comparison of different air cooling options for CPUs. What I would find useful is a comparison of these with a watercooled system. All in one kits but also perhaps something like this kit from XSPC.

The kit above has different sized radiators so it would be interesting finding out how much cooling is required to dissipate the heat produced by different builds.
