Enough pump?

At the moment i have a small-ish loop consisting of:

EK supremacy block
EK Crosshair V formula Z block
240mm EK radiator
EK 25cm tube reservoir
EK 4.0 (700lph) pump

I use to have a watercooled GPU but it didnt last too long since i sold it for my current GPU. I am thinking of expanding and upgrading my loop with a Phobya 200mm radiator, RAM block (mainly for aesthetics) and eventually a EK GPU full cover block to go SLI on my GTX 580, in the future if i can find one cheap.

My problem im having is that my pump is a little on the weak side compare to some of these D5 pump's people use.

I want to know if my pump can handle it if i were to just stretch the loop by the 200mm radiator and the RAM block?

In terms of head and speed, are all d5 pump's the same?

Cheapest route would be to add another EK 4.0 in series... this will beat the pants off a d5 for and save you a load of money over binning the one you have

That is what I have and I'm running 4 blocks and a 1260 rad with loads of spare capacity

i would say go for a d5 pump and save the hassle of having 2 pumps

I cant really see much hassle in having two pumps. I am leaning towards getting another pump considering the costs.

Hi, been using one for just over 3 years with the latest Gigabyte Easy 6 utility, gaming the pump hovers around 2600rpm quiet as a lamb, idle's round 1600rpm.
