I was operating under the assumption that a lower cpu to ambient or cpu to chilled water differential meant more cooling (CPU is closer to room temp or water temp when the delta T decreases). That presents a problem though: How can the delta T for CPU-air respond in a different direction to flow rates than the delta T for CPU-water?
I really need an old throwaway motherboard so I can get tolerable diode readings again. Will see if it is possible to resurrect my KT133A board again tonight.
