There's plenty of room for fluff reviews and "good enough is good enough".
Hooray!

I have already heard them and somewhat understand them, but still have yet to see any real evidence it is usefull to the average Joe.

Truth is you have to be mentally off kilter to spend thousands of dollars to test $40 waterblocks. I've cobbled together an almost acceptable test rig for a few hundred, and it's a pain to use. But I enjoy going downstairs and fiddling with it and making my little at home heat transfer discoveries. It will be really satisfying to have it all come together and post a new waterbock comparison article here on Procooling. Would you honestly be satisfied if that article DIDNT include a pressure drop vs flow rate chart? Or a C/W vs flow rate comparison for all blocks? The readers of this site are sophisticated enough to deal with that I think. Now the statistics behind whether a line running through points on a graph is meaningful or complete bullshit may be a bit too much for the average reader of this site. That doesn't make it any less important a question though... [/b]

Your refering to procooling.com and I am not. I "guess" I would expect those things to be in the review here as maybe 2-5% (that percentage unfortuantly doesn't seem to be rising, but falling) of the people on this site might be able to use those numbers to their advantage (if they actually do is another subject) and especially being we are more anal about things here. But I am not talking just about procooling.com. I am talking about my own site and the hundreds of other tech sites that do not have readers and never will have readers to the same level as a few here are. I see consistantly on many sites where readers get pissed off at how anal some are about testing. They don't want all this tech lingo and graphs. They just want to be told this is better than that and have a temp number from your test to show it. I feel this will never change as there is no other product in the world that has accomplished this even the one's with standards tagged on them like "UL" and "SAE" ect...
Maybe I am just not sure what "good enough" is anymore. If I can say with some reasonable certainty that block A is better than Block B on my system then I think I can live with that. I really don't see (yet) how the C/W value on my test system is going to be usefull for anyone being it will be impossible to replicate that C/W value on any other system (especially now that you say proffesional labs can't even do it with $100,000 equipment!). So I don't really grasp why it is important. Seems to me a temp number would be just as usefull and more easily understood to the average reader. Hell most people don't understand a lower C/W is better than a higher one!
But you say you have only got a few hundred into your system and you feel your capable of doing these measurments? If that is the case I will have to re-read your articles again and try and emulate your setup as I can handle a few hundred $'s! Ben is talking about what $9,000 just for temp monitoring? All I can say is **** that, I got better things to piss money away on strip clubs included!
I have been pondering what is good enough for a bout a year now when trying to put together my test bench, but I have yet to decide where I need to stop thinking and when to start doing. And if I start doing will it be good enough.
Bah, back to work....
