From posts I've read from those who have your block and are happy with it they are reporting up to 1C higher water temps at idle and 1-1.5C higher water temps at load in O/Ced systems. This makes sense as the extra heat removed from the chip has to go somewhere, and with a lower flow helps it show up more.
So would not the temps on other blocks have to rise closer to 1.5C due to the warmer water combined with the slightly lower flows?
This shouldn't be taken as a slam on the WW as the CPU is the most important point for cooling. And a 1-1.5C change in temp of the NB & GPU will make far less differance in a system's total O/Cing effort than a 5C differance will at the CPU!
And could you not also increase the width of the impingment slit slightly combined with a higher grade pump than the Ehiem like a Iwaki MD-15 or MD-20Z? This should allow the stronger pump to maintain the lower temps reported in testing at lower psi while also keeping flow high for best performance of other blocks? This would seem to be the solution for those concerned with the lower flow of the WW compared to other blocks when used in a 3 block system.
Cathar, just how much would you estimate the slit should be opened up to gain this? .5-1mm??
Although as noted above the CPU is the more important place for cooling. So the MD-20Z could also increase the velocity through the WW with a smaller increas in total flow but gaining perhaps a 6C + advantage at the CPU.
Some interesting possible options here, depending on where you value the cooling most.
