A couple of things to look at would be the mechanical fan (clutch) might not be engaging properly. They wear out. Was your AC on at the time?

Waterpump is a high failure part on every I’ve ever had.

All sorts of things to check. Are the upper and lower radiator hoses really tight? Or just spongy? Do they stay tight several hours after you have stopped driving? Or relax as it cools?

Others can add their input.
