Currently have 2 loops, 1 cooling 2x 260's oc'd, and 1 cooling i7 920 oc'd at 4.0. cpu has 240 mm rad idling at 38-40C while gpu's idle 45-50C with the same, 240 mm rad. Atm i cannot afford a fourth pump, but id like to add a third for a backup, so to beable to backup both pumps with 1 extra pump ill need to make it 1 loop total... if doing so ill still keep 2 reservoirs... but ill add 3 more 120 mm rad's makeing it a total of 7x 120 mm rads, so my QUESTION is... is it likely my temps will stay the same combining loops or more likely drop adding more rads.
