All of the mosfet blocks for the current revision (Non X58) all share the same inlet/outlet design. The inlets/outlets go from 11mm ID down to roughly 5mm (I don't have the exact measurements in front of me, I'm at work still), and this just kills flow and causes significant pressure drop, I had a leak through a worm drive clamp while doing pressure drop tests.
I will not be able to provide pressure drop results up to the standard 4.5GPM on these blocks because the blocks just can't handle the flow rate or the pressure build up at the inlet, and the amount of restriction in these blocks is alarming to me.
My personal recommendation, do not run the current revision BP mosfet blocks in your CPU loop. Add them to your GPU loop or dedicated chipset loop, keep them out of a loop where pressure and flow are needed.
edit:
I was giving Vincent ample time to respond to my findings before releasing my any information. I really want to make sure this problem is being addressed.
