Mhh for one i dont think he bases his assumptions on "a semester of mechanical under [his] belts", like i said he's a pro. Do not underestimate him.
For two he maybe has badly formulated his thought, please bear with him he's a technical guy. Ya know, all technical guys have difficulties being clear to other people. (and to suits, but thats another problem)
In this very case he tried to be short and to-the-point, since this very topic has been beaten dead and buried 50ft under a long time ago.
What everyone agreed on, was the basic thermal equation:
q=UAdT
where A is the surface area of transfer. The higher the flow, the higher A is (and the lower U is due to laminar vs turbulent etc..)
That's true for WBs, thats true for rads, thats true for air on a heatsink, thats true for air on a rad, thats true for your car radiator.
Putting rads in parallel will increase the dT, while not killing A too much since the mean water path will be shorter (ie backpressure will be lower) - so resultant flow wont be divided by two (compared to flow in series setup).
The result, a parallel is winning.
Ah and please stop flaming ppl , read the first (sticky) thread on this forum....
