While my goofball persona is relatively deflated:
#3:
I didn't have 'a question' per say; though my sense that the grammar, punctuation, page layout, coompositional refinement & etc. of the original post is a step below that which I read in say the Journal of Neuroscience does imply questions.
And I wasn't prorosing two changes that I was aware of...

A big three Dimensional graph.
X is is the flow of water through the radiator.
Y is the flow of air through the radiator.
Z is the measure of water cooling. ( raw degrees or perhaps in watts to sync with X )
Color of Z indicates the difference between intake water temp and air temp.

Importantly, a subset of Z-colors can be chosen for display: say 5, 15 and 25 degrees in blue yellow and red, so as to avoid a huge mud collored cloud.

Set up a system with automatic pump and fan control and data logging. Set it to scroll water flow from min to max and back and forth on one time scale; scroll / adjust airflow independently on another time scale; adjust the water chiller controlling X temperature in on another scale; adjust / scroll / wander air temp in independently as well. Invite some uncontrolled & unmeasured variance: air pressure, humidity, set it near a window where sometimes it is in the sun and sometimes not.

Set this up, start the data logging, and let it run days or weeks. Dump the data into a database and render a few charts. Select out a Z-color of say 10 degrees and render it. Hopefully, it will show a big cloud of points in the 3D space. If the cloud is spikey, holed, or slabbed on X Y or Z, something is amiss: something important uncontrolled / unmeasured, independent variables not wandered properly, or data sensed / logged in error. If it is a nice fluffy pancake on a hill, dense on the inside and thin towards the edges, then it is a neat description of the cooling of a radiator across varied water & air flow & input temps.

Annyway, that is what I thought of on reading Mr. Grumpy's post. Feel free to take it as a non-sequitor, just some tangent that I thought of... I like that he shares what might be more rambling and perhaps less than polished notes / thoughts in progess here. I wouldn't want to be seen as 'complaining' in that regard.
