I usually use this to calculate my wattage, then look up the specs of different radiators and their heat dissipation either from the manufacturers or from places like skinneelabs.com or MartinM's site.

It's hard to get good numbers for any of this stuff because the variation is so high depending on mounts, trials, TIM, ambient temperature, and other conditions. It's more art at this point than science, though there is a lot of science behind it, just no real unifying solutions.

there is a wattage calculator floating around some where, it was made in 2006, but it works just fine, but you need to know the stock volts/tdp to calculate the overclocked tdp
i forget where i found it, but i'm pretty sure it was someone on overclock.net

edit: let me have a look around and see if i can find it for you
edit #2: heh, it was the second result from a search of "tdp calculator" http://www.overclock.net/application-programming/126350-heat-cpu-w.html

How do skinneelabs's tests translate to dissipation?

When I decide to use one I use that, but I found it a long time ago here.

Because components only use about 60% of their TDP at stock, I like to add up the total TDP of all of the components I will be cooling. This information is readily available online with a simple google search on the manufacturer website.

After you factor in overclocking you are back up to around the TDP of the product as nothing other than extreme overvolting will put you past that level. I have accurate measuring equipment and have found this model works very well.
