it really doesn't matter with the heat output in his system. i'll guarantee that there is less than a 1°C drop in temps from the inlet to the outlet side of this radiator. in these closed loop systems, the water in the rad will be at basically the same temp as the water in the pump or the water in the CPU block. unless you have something super hot, like a 600w pelt, the water temp won't change much from one part of the loop to the other.

one reason to have the pump out connected to the rad in is head and turbulence. the more turbulent the water inside the rad, the more all the molecules of the water get in contact with the surface of the rad and more heat is lost over the rad. of course the same applies for having the pump out connected to the CPU block in... more heat is picked up from the block.

and yes, OP, we need load temps.

wow, ~40°C on air cooling on a quad? that's really good. what's your ambient temp?

i'm hitting 40°C at load on my sig CPU with 26°C ambients and on a 360 rad.

i'm really have a hard time believing that you were getting the same temps on air. i've had 3 cpu's under water, 2 of them quads, and it's always been at least a 10°C decrease in load temps when on water.

well that SS only has prime up for a few seconds, maybe a minute, it's not done with the first iteration yet... that's not a true load temp, but it's close.

what are your ambient temps?
