Got my setup working today, CSP-MAG, BIP II, Polarflo TT GPU block (the performance is not good, but it's the only one that will fit my 6600GT AGP card), MP-05 Pro.
I'm currently using the N-02 X nozzle, and while I can't give you accurate performance numbers, I will note that my CPU idle and load temperatures are lower then my motherboard temperatures. However, I don't have very good case airflow (I'm trying to keep things quiet). The onboard temperature sensors show a 3 degree delta T between idle and load. And the bubbles aren't 100% out yet
Needless to say, I'm happy with my first watercooling attempt and the MP-05 block.
Forgot to note, this is on a 2.8C Northwood @ 3.2, 1.625 core V
