Did a sit and see. 20 minutes looking good. Ok until i ramped it up to 4500 rpm for 2 min. Gauge went to danger mark quick. Took it back to 900 rpm but it fell slowly but never safe. Did 4500 again and it went from below that danger line to the top in 5 seconds. Let it rest at 900 for a minute but it did not lower. Shut it down af 3.10 my time. 51f in my yard. Flashlight did not see any steam. Nothing to see nor smell. Fan spinning where i could not see blades fast.
Just a bump in case
When it starts to over heat, have the heat on full and feel the temp of air. If it cools off as the motor is overheating you have no coolant flow. I will bet if that is the case you have a bad head gasket.
It's like a window fan, sits in front of the radiator, typically, though I guess it could be behind it. It comes on when the coolant temp rises above a certain point because the mechanical fan alone can't provide enough cooling. Some cars, eg BMW use a variable speed fan which complicates things. These fans may not need to come on when it's 70F and the car is just idling. But if you've driven it hard, have the AC on, it's 85F ambient, and you stop driving and let it idle, it should be coming on. Also, I believe you said you put in a new fan clutch too. Is it working? Simple, crude test is to use a rolled up newspaper to gently try to stop the fan from spinning. When it's cold the clutch should be mostly free, so that the newspaper easily slows the fan down and stops it. When it's hot, it's much harder to slow down with the newspaper. That translates into the fan spinning slower when it's cold, faster when it's hot. If it's not working right, you could have low airflow when it's hot.
Did the Taste Of Home magazine test. Could not stop it cold nor hot. Shredded my magazine.

When I was a kid, my friend and I each stopped a spinning fan by hand. Being boys, we always wanted to find ways to prove how tough we were.
From the intake or discharge side?
Discharge (engine) side. Gee, we weren't savages. Besides, the intake side, where the spinning blades are relatively sharp, is up against the radiator, tucked inside the shroud.
