Is a single D5 pump enough for this water loop?

Wondering whether a single D5 pump is sufficient to run the loop I am building with appropriate flow etc.

My setup is going in a Cosmos II, which is large so will probably have around 3 - 4.5 feet of tubing (3/8 ID / 5/8 OD) between components total.

Parts on the loop will be:
Pump - Single D5
Reservoir - EK-XRES 140 D5
CPU Block - EK Supremacy EVO
Radiator 1 - Alphacool NexXxoS XT45 Full Copper Triple 120mm
GPU - EK Block
Radiator 2 - Alphacool NexXxoS Monsta 120

Would this still be sufficient with a second GPU block?

Also, I know that the 2 rads may be overkill but I'd like to use both in my loop.

Thank you!
