Radiator Position in a Loop?

I was hoping to get a bit of confirmation on position of a radiator relative to a loop.

Intuitively I would think that if you have a radiator after each component being cooled the overall temperature of the water should be cooler for each component. But I thought I remember reading that the position of radiators relative to components in the loop don't really matter because of the speed at which the water is pumped around.

Is that true?

Thanks.

Yes its true, it doesn't matter where the radiator is in the loop. The flow of water is continuous, and you are not really directly cooling just the water going into the cpu block, you are just cooling all the water in the loop.

For multiple radiators, and multiple components (2x rads, GPUx2 and CPU+Chipset) I personally have never seen a real difference with both of the rads before everything, (ie: Pump --> 2x Rad --> GPU --> CPU --> Chip --> Pump) versus interleaved: (Pump --> Rad1 --> GPU --> Rad2 --> CPU --> Chip --> Pump). I have tried both in the past, but there was no real noticeable difference to me - maybe a degree in there somewhere that I did not really see - but overall it was basically the same.
