So no idea what is wrong - I fear the d5 is simply not powerful enough for my loop...
See video here of the very poor flow:

Loop order is:
Pump - rad 240 - rad 480 - cpu - mosfet - rad 480 - dual gpu blocks - chipset - res
Also changing the pump from 100% to 1% (via aquaero) has absolutely no effect (percentage as given in top right corner on aquaero) - is my pump defective??
Hoping someone can please help!
