Is running two dual radiators in series in one loop a good/bad idea - I suppose the question is, would a decent pump (18W DDC) cope?

E.g. res->pump->rad->cpu->nb->gpu->rad

I guess it would be best to avoid a very restrictive CPU block for this type of setup?
 
Adding anything to a loop increases restriction.

In an ideal world you should aim for more than 1.5 gallons per minute.

Adding an additional rad will decrease the flow rate so the lower the restriction of your cpu,nb and gpu block the better.

This is a handy tool:

It will give you some idea of the drop in flowrate/performance.

May be slightly better if you could have it as follows:

res->pump->rad->cpu->rad->nb->gpu->

They say though that the water will reach equilibrium after a while but it does make some sense to cool the water after the cpu so the nb and gpu are getting cooler water.
 
Thanks - will look at the flow rate estimator, looks useful!
Having the rad between cpu and nb would be tricky for my setup (external box, would have to go out + into case again).
