Interesting! What does the rest of your cooling system look like- radiator, water pump, thermostat?
My car runs right at the thermostat temp (180) if I’m doing 30 or more and it’s under 90 degrees out. Never had an issue with the temp climbing if I’m moving at speed unless it’s pretty hot out. My fans pretty much only run if I’m stopped or stuck in traffic. And wired with both speeds I run almost exclusively on the low speed. I’ve only had the high speed kick on when it was 105 or better and I was in the city catching all the lights.
