Yeah absolutely, at most you're talking a few degrees difference (if that).
Gone are the days where I obsess about loop order, and whether to push, pull or both.
At one point I got so obsessed I'd be tearing down my loop every other day, trying different thermal compound, different fan configurations etc and the difference was minimal.
As has been stated already, the only "order" there has to be is res before pump, and in the past I've not even used a res, I went for a t -line instead.
To be totally honest I liken all the above to the heated debates about thermal compound application, generally the differences in temperatures (unless you apply a hell of a lot of thermal compound like you're spreading a peanut butter sandwich) is minimal, whether you apply using the grain of rice method, line, cross etc.
