Help Me Cool Down

It's not just the fan speed that's down. It's the pump speed.

You need flow to cool the engine. Air flow and coolant flow. You've lost both.

Keeping the coolant in the engine is bad. You can't give up flow and not expect issues.

I agree - up the pump/fan combo speed. I do have a high efficiency water pump so I imagine it’s about a normal amount of flow being undsrdriven.

The fan is about 3/4” from the rad and the shroud encases the entire fan.
