Why do the Overclockers.com(new guys) test results have a lower C/W compared to Bill Adam's (old guy) test results?

JoeC's die simulator has a larger surface area, therefore lower C/W numbers.

It's not that serious, we're just keeping CPU's cool enough that they don't burn up.
AngryAlpaca said:Well if you want to buy a crappy waterblock for a high price, YOU can go for it. "So they don't burn up"? They don't have issues until the 90s. Why don't YOU just put a passive heatsink on? It will keep it cool enough, so it doesn't burn up.

The goal of watercooling, orignally anyway, was to have a quieter way to cool the CPU. I went with watercooling so that the heat from the CPU isn't being thrown all around the case and is contained. Everyone around here wants the freeze their cpu with as little effort as possible
No, what happens is that the throttling valve drops the extra pressure from the bigger pump. All other components behave exactly the same, dropping the pressure according to the flow rate.Diggrr said:Does anyone know what pumps the two guys are using? I read for a while but coulnd't find it.
I believe that if you simply regulate the flow on a pump, the pressure stays the same (works that way in hydraulics and pneumatics anyway). Therefore any test with a "lowered flowrate" would still be at pressures that most magdrives can't achieve if their pumps were like Iwaki's or something.
Wouldn't that also affect c/w? as well as the comparison of c/w in their systems .vs c/w achievable in MY system?
As for pressure drop measurements, I'd think that .5 psi pressure drop against an Iwaki would change tests little, however against a maxi-jet....well, you get the idea.
Just wondering

Not if the testing is done properly Caffinehog. Bill uses a 'standard' system typical of most H20 systems? Have you ever seen a picture of his situp? Looks like a mad scientist lab! AFAIK, BillA has the most comprehensive test bench out there for testing water blocks. If the C/W in ANY test is based on anything EXCEPT the block itself, then that test is no good in my book. The goal is to isolate the blocks performance.Caffinehog said:
The C/W also depends on the rest of the system, not just the block. Bill uses a very standard system that would be typical of most watercooling systems. This allows you to compare the blocks more fairly. What the other guys have may be better than Bill's setup.
