Pump pulling from CPU does it make a difference?

[Jamesrt2004]

surely foams from air etc and pums just mixing it? maybe air still in the rad thats coming out etc.. ??

(I think)

Reservoir before pump, in order to prime the pump easily and bleed. Component order, what ever gives neat/shortest tubing is the way to go in my opinion.

Order will not make a difference as Vapour said, well nothing that we can really measure without stupidly calibrated/accurate thermometers.

I pretty much agree with that, I tried 2 configs for my setup and the results were identical near as dammit.

Firstly and the one I stuck with as the tubing was a lot shorter.
Pump - Radiator - GPU - CPU

And the one I didn't use.
