Hello,
I think I did enough research and reading to determine that the direction of the airflow through the radiator should be from front to back. In that case with my fans, that means that they are pulling air through the radiator. That is accomplished by putting the 12VDC signal into the black wire on the fan and grounding the blue wire on the fan. The black wire looks to be a 16 Gauge wire and the blue one looks to be 14 Gauge (it looks a little bigger). I ran the fan with it hooked up this way for a few minutes, and could not detect any warmth on the black wire, therefore my conclusion that even if the black wire is slightly smaller, I am OK sending the positive signal down that.
Am I missing anything, or any thoughts on this?
