Also, the rpm sense wire should be hooked up to the cpu fan header. It doesn't just read rpms, mine kicks the fans up BIG TIME when it start to heat up. If your fans aren't ramping up during load, then something is wrong. My h80 stays nice and quiet until full load, then it sounds like the pc mite lift off my desk.
Cheers for the confirmation! I don't remember the radiator fans changing speed based on temperature, only via the button on the unit. I replaced the fans with Akasa Apaches, though, and they're dead quiet now regardless of how fast they're going. The other fans in the case, however, do ramp up as the temperature rises.

Now put those fans blowing in the exact same direction but place them on top of your heatsink. Now you can see that the way the blades are pushing air up is NOT pushing it through the radiator but only a small breeze is being pulled off the top of the radiator and dissipated around the blades. It cannot pull through that radiator like it can PUSH through it. Add to that the case holes in the top of the case and you have an even worse issue.
Already ruled that out, configuration #3 is pushing air through the radiator (see picture in my post above) with the same pattern of results. It could be a weak pump, how much vibration do you get from the pipes when under load, or any pump noise?
