In normal usage, your CPU-dedicated 120mm radiator will see ~120 Watts at full CPU load, whereas in a serial loop composed of a 120 + a 220, this load will be shared by the ~equivalent of a triple rad, or ~40 Watts per 120mm fan if you will. As far as your triple SLI is concerned, at full load your dual rad currently "sees" ~360W, that's 180W per 120mm fan. If you serialize, this value will drop to 120W!
From my understanding, if you are using too many rads for this setup, you are removing the radiator cooling abilities as a factor in the change of temp. The temp differences between each loop will be based solely off the flow rate and how the blocks are affected by such.

Further, in my experience, many users have temp issues because their radiators are inadequate for their setup. They feel that a dual loop will correct this, but fail to understand that any amount of radiators can only dissipate a set amount of heat, regardless of the setup.

Anyways Im way behind the learning curve on the thermodynamics involved; I just wanted to see the opposite end of the spectrum .
