Almost forgot. I do agree for more exact testing it will be interesting to note however who will that level of testing be the most beneficial for? The end user who cannot ever recreate those results? The companies that make the product? Both? If we assume both then why is this so?

Any way my bet is that it will the most beneficial to the companies to be able to see this kind of result. Were as some of the end users only want to see how well will pump a perform with waterblock b and rad c. Of course there will be a 2c or so margin for error at the most but for the end user is 2c close enough for them to make a determination? It will probably be closer to .5c but as billa pointed out in his test equipment he only found .7c difference between the highest and lowest. Will or can they ever be able to get the same results as you, I or bill if they are not using a high presure pump. The answer here is of course no. Some blocks will have a higher pressure drop witch will in turn cause that system with pump b to perform at a less than optimum level as compared to the same system when using a differrrent block with less restriction.

Anyway enough. Suffice it to say the testing will be having a second round when I've collected all the pieces for the next level of testing. I like you want to see these results.
