oh sorry, it's rated at 250L/H, and about 35 or 40cm head,(and a HUGE 6w power draw!) I've streamlined the flow paths though so it does almost 300L/H (like porting an engine intake manifold)
Before I chopped the pump up I ran it through my new U1 heatsink block so I could get some sort of baseline performance figures to compare it to.
The copper base is only 1.7mm thick, I've deliberatly limited the copper to water surface area (about 25-30mm^2) so it really is a test of how the turbulence from the impeller effects the boundary layer, the impeller is around 1.5mm above the surface of the copper.
I have another identical copper plate that I intend to set up a "conventional" water block using the same surface area(same shape even) as the pump block, like a control in an expriment.
Though I may be able to get away with simply leaving the pump-block un-powered and pumping water through the block with another pump throttled back to the same water flow, we'll have to wait and see...
