Guys... Chill out!
There are many ways of dealing with this issue. It can be solved with simple electronic or even Intel's i7 processor. And it doesn't matter.
I like the idea of PWM controling the fan, and I'm thinking of building the "temperature Management System" (as I call it), based on Atmega328 (which i have anyway), with an LCD screen showing outside temp and coolant temp, with a backlight color changing accordingly to the temp (yellow - too low, green - proper, red - too hot). And not only using PWM channel to control radiator fan, but shutting and opening the grill block.
I'm hoping that soon I'll be able to post my project details.
Cheers!
