Summary:

Our first test was to start up our ATS-V. The ambient temp was 80°F. we let it idle until the ECT stabilized rose to 212° which is just below the car's fan-on temperature. Then we set the Fast&Cool in front of the car. With the unit sitting on the floor, it's outlet was pointed right at the V's cooling air intake. We turned the Maradyne on high and waited. Within five minutes the ECT was 201 and at the end of 15-min. it was 190°. Clearly, the Fast&Cool does very well as an auxiliary cooling fan.
