Just saw a build log video were a guy said that you had to be aware of the flow direction in EK GPU blocks due to the jet-plate design, so i have just had a look at my EK block on my GTX 970 G1, and it seems i have been doing it wrong, as in the loop config i have now it pushes the water backwards through the jet-plate, so i must be leaving a ton of cooling performance on the table, as the water flows worse backwards it would seem even though EK claim it doesn't matter hints why that don't openly say which is the optimal flow direction, but it is quite clear that is does matter.
The red line is my current and the green line is the optimal flow direction:
I'll have have to change it for the new loop config, as my goal is to optimize my cooling config for my hardware, as i have made alot of mistakes in the current loop... So need to fix it all soon. But worst of all is this tight tube that is bend very hard, i think i lose alot off pump pressure due to it maybe kinking abit.
So with the radiator, GPU flow and pump/res changes in the loop then i might see a huge load water temp change as my water gets about 35*c while during the torture test called The Crew, so i think it will be possible to knock off 5-8*c of my water temp.
