I'm 150 miles SW of you in Yuma. It was 112 here yesterday. Perfect for testing my cooling system after major changes this winter. 85 K20, 350 Vortec, 2 row aluminum radiator, dual 11" spal fans and Dakota Digital fan controller. 160 t-stat.
Primary fan on at 195 off at 190. Secondary fan on at 205 off at 195.
All new Vintage Air a/c system.
At 112 yesterday, it would stay between 195-200 as the fans cycled. Then I turned the AC on and it dropped to 185 and stayed there no matter what. WTF I thought?
Turns out the fans both go high when the AC is on and they move enough air to keep it at 185.
Works for me!
