The extra cooling from recirculation might make up for the less flow (in the case that you used 2 high flow pumps) ?

Also, mag drive pumps have barely any pressure, so it's hard to force the water at maximum flow rate though the system, so the recirculation valve in theory would use water that wouldn't have been used in the first place since flow rate would peak out, unless you raise the pressure.

If you had the same setup with pumps that would put out a few PSI of pressure, then you would want all the water going to the blocks since theres enough pressure to move it all through without it slowing down. A recirculation valve with high pressure pumps would hurt performance since pressure is lost.

These are just ideas though.......
