What you've plotted is the basic variation in convectional efficiency with viscosity. What I'm having troubles with solving is what's occuring within the G* blocks
before the convectional action. Increased viscosity will definitely be interfering with the longevity of the "turbulation" effects that assist with the block's increased convectional activity.
Have completed re-drawn plans for the G4/G5 which should improve things slightly, and should not be at the expense of "plain water" performance.
Still, it is rather an interesting relationship, and definitely something for people to consider before dumping heaps of glycol in their cooling loops.
