Is 2x EK Coolstream 480 XT enough for 2 loops, VGA & MOBO+Processor+VRM

I'm planning my next build and I have a question regarding radiators.

Equipment:
2x evga 780 Ti in SLI
Intel i7 4960x
Asus - Rive
Corsair 900D

I am planning to watercool them with the following kit:
VGAs: 2x EK-FC780 GTX Ti - Nickel
Processor: EK-Supremacy Elite - Intel 2011
Motherboard + VRM: EK-FB KIT RE4 - Nickel CSQ

Pumps: 2x Aqua Computer D5 pump motor with USB and aquabus interface
Brain: Aquaero 6 XT

Fans: Either Noctua NF-F12 or Corsair SP120 PWM Quiet edition, 16+3 for intake in the front

I'm planning to control the fans and pumps partially based on the coolant's temperature that is coming out from the radiators.

I want to implement two loops:
1st: res-pump-VGAs-rad->res
2nd: res-pump-proc-MOBO-VRM-rad->res

I want to monitor & control the fans/pumps

The question is, can two Coolstream 480 XT handle the load (with push&pull vents), or do I need to implement a 3rd radiator somewhere?

If someone could also advise on the fans that would be great smile.gif

You'll be fine. General rule of thumb is 120mm of rad space per waterblock plus an extra 120mm on top of that. If Mobo and VRM are separate blocks, count them as one block since the motherboard doesn't put off much heat.

2 480 rads would be plenty for that rig, you could even get away (with average temps) with just 1 480.
