I would agree that the needless flaming of newcomers and "Post your CPU temps here" people is not a good thing. But I fear you are headed pretty far into the "placate rather than educate" side of things now which is an even worse thing.

Ok, I'll take that as "some progress".
So is there any hope for a DIY block maker to measure anything?
I don't know how [H] conducted their test, which would probably have been more accurate, if they had repeated it three times (at least), no? They should have at least been able to see that there's a problem with their testing, because of the variance, no?
Ok, so what about using a thermal pad: wouldn't it give more consistent results?
Otherwise, I can see what's emerging here, in what GTA said. Since the power applied, which is an unknown to a home user, will result in various CPU temps, system to system comparisons aren't valid, and we have to make that clear, and understandable to our new guys.
Example: The White Water waterblock was tested (uinder a specific set of circumstances) to have a C/W rating of 0.19. So if the source power is 50 Watts, the CPU temp will be 0.19 * 50 = 9.5 degrees above ambient.
On someone else's PC, if the power is 60 Watts, either because it's overclocked, or because it's a different CPU alltogether, whatever, then the temp difference would be 0.19 * 60 = 11.4 degrees above ambient.
Add to that, the different set of circumstances, which will include the flow rate (most important) and the different cooling solutions, and room temp.
