enough flow for my loop
 

my question is
after adding component in my loop do will have enough flow?
now i have 1 Gpm (taken from Koolance flow meter)
this is what i have in my loop
it wil be more easy with a pic

Swiftech Apogee HD
Koolance Rampage IV extreme water block
2 x Kollance HD7970 water block in serial
3 x EX360 rad
a lot of 90 degree fiting
a Koolance flow metter
2 x Koolance quick disconnect
on this loop, i have 3.750 LpM (1 GpM) with 2 D5 Vario at speed 5 (in serial)
i will had another HD7970 and 2 x EK Dominator GT water block
do you think my flow will be to low?
if i connect my GPU in Parallel, this will help for having a better flow?
do you think my both pump will be enough???
or its a perfect setup for a pair of DDC 3.25 ?
or i need to do 2 separate loop?
thanks for your help

I think your pumps are more then enough for this setup. One pump might be pushing it with 3 Rads and all those components and fittings, but two will for sure be good.

I had my Video Cards in both Serial and Parallel and did not really notice a difference in temps or flow rate.

Should be fine. So long as the fluid is moving at a decent rate you are good. Nice build by the way.

Flow rate is hugely overrated. Anything over 0.2 gpm will be fine. I would suggest removing the flow meter though. The Koolance meters have something like a 30% pressure drop.

the meter itself causes the drop ... or is it just inaccurate reading?

The meter itself I believe.

Correct. They are rather restrictive. But I guess with two pumps he shouldn't ever have a problem with flow rate, even with the flow meter.
