Coffee cooler

I like my morning coffee strong (and sweet). And normally I like it right now. So here I am sitting in front of my desk, "ckecking my emails" as it were, waiting for my coffee (black of course) to cool down enough to be consumed.

Old mate here to my right has just suggested that I water it down with a little cold water, or even ice. From experience, I can tell you that this seriously alters the flavour of the coffee. I don't understand why, but watering down already brewed coffee spoils it. So, of course, I have a complicated and expensive solution. I'm thinking a stainless steel "dipper" heatsink, with a large fin area, and two thin pipes leading in/out. These pipes will go to/from a vessel containing iced water. You dunk the heatsink into your brew, hit the switch, and icy water is cycled through the heatsink, rapidly chilling it to a more moderate temperature.

Bonus deluxe version is of course designed with no pump, using convection as the motive force to move the coolant in/out of the heatsink. It is callibrated such that once the coffee (or soup - the possibilities are, well, um, limited. hmm.) - has reached the callibrated temperature, the convection process stalls and the cooling effect ceases, with your coffee at *exactly* the right temperature.
