2xD5 vs 2xDDC long loop comparison (serial scaling)

[luke997]

Thats because u lacked the restriction component.

In a open flow, a D5 is better.
Once u start connecting things down the loop, the DDC's head pressure works out the restriction and pushes water.

What do you mean by lacking restriction component?

This is a closed loop with 7 waterblocks, 3 radiators and ~ 1m of tubing, there should be enough restriction for DDCs to shine.
