I am assuming 1.5m of 3/8" tubing and all barbs are converted to 3/8".
I am using a MCW55 as I have not plugged in the numbers for the MCW60 yet.
Assuming 90 CPU Watts and 50 GPU watts, and all temperatures are based on RoboTech's die simulator.

Anyway, as an approximation, I get 2.5 LPM flow rate.
Fans @ 5v
Water temp at exit of 2nd rad: 8.87 dCaa (degrees Celsius above ambient)
CPU temp: 22.47 dCaa
GPU temp excluding TIM: 9.4 dCaa

Fans @ 7v
Water temp at exit of 2nd rad: 5.93 dCaa (degrees Celsius above ambient)
CPU temp: 19.52 dCaa
GPU temp excluding TIM: 6.44 dCaa

Fans @ 12v
Water temp at exit of 2nd rad: 3.92 dCaa (degrees Celsius above ambient)
CPU temp: 17.52 dCaa
GPU temp excluding TIM: 4.43 dCaa

Leaving the fans at 7v, and changing the pump to a MCP655 @ 5, you'd only get a half degree or less improvement.

When you assemble, please do the bucket fill flow test and let me know how close I am with my approximations
