Electrical - on low speed the fan draws 16.5 amps. On high speed the fan draws 22.5 amp, numbers bounced around some so it's a middle number.
Once the engine hit 210 I jumpered out the switch and turned the low speed fan on. Once the low speed fan cooled as much as it could, probably after 10 minutes, I engaged the high speed to see how much farther down it would go. Ambient was 101 degrees when I measure the numbers with my Ratek IR gun. 185 degree (rated at fully open) thermostat.
Low speed got the temps down to 167, high speed got it to 165 and that I believe is when the thermostat was fully shut.
I did capture airflow numbers. Mechanical was done at idle speed, which is when airflow is at it's least. No shroud in the stock setup, small diameter 4 bladed solid mount fan.
One final set of numbers, it got to 106 yesterday by the time I came in, today it got to 104. I lost 6 lbs, despite trying to stay hydrated. Only 50 more to go, lol.
