At 1.5gpm, and a Panaflo H at 7v (which typically offers around 10% better than a Yate-Loon at 12v in my testing)

PA120.2 = ~0.036C/W
MCR220 = ~0.038C/W
PA160,1 = ~0.055C/W
PA120.1 = ~0.072C/W (estimated)

"Worth" depends on the heat-load. At 100W, PA120.2 is ~0.2C better than MCR2220. At 250W heat-load (CPU + GPU), PA120.2 is ~0.5C better.

Comparing PA160.1 to PA120.2. At 100W, PA120.2 is ~1.9C better than PA160.1 At 250W heat-load, PA120.2 is ~4.7C better than PA160.1.

Comparing PA120.1 to PA160.1. At 100W, PA160.1 is ~1.7C better than PA120.1 At 250W heat-load, PA160.1 is ~4.2C better than PA120.1. Then again, not usually best to run a single 120.1 with 250W of heat load.

i.e. A PA160.1 sits about exactly mid-way between a PA120.1 and PA120.2.
Thanks, I'm putting together a new rig. I already have a PA120.2, but I'm thinking of using a separate loop & rad for the cpu when I go quad core.
PA120.2 for 8800's SLI & northbridge & PA160 for the Quad is what I'm thinking.
