If I remember my fluid dynamics and heat transfer classes correctly, you will have to be careful of a few things:
1) that the pressure drops/friction losses across all of the separate circuits are of similar magnitudes. If not, you may end up starving one of them as the coolant takes the "easy" way through a more freely flowing one.
2) It is possible, IIRC, to have to fast of a flow rate. If there is not enough contact time, very little heat is transferred until the deltaT is bigger -- defeating the purpose of liquid cooling.
Thermo and fluids were more than 20 years ago now, so I could be wrong. :frown:20 years -- I've become an old fart:frown:
