No actually. I must have a crappy IR gun. IDK why but I was measuring in F. There seems to be quite a lot of temp loss on the hoses. So those were hose surface temps, not actual coolant temps. All I wanted was to determine the difference of inlet and out let temps at fan start up and after they had been on for a while so I could eliminate the new Tstat as a culprit. I think this accomplished that (fingers crossed!!).

In any case I don't think that is sufficient cooling. The car never overheats but it never gets cool either. Fans work as they should and air is passing through the condenser and radiator. I think it's time for a new radiator. Flushing does not get rid of the oxidation and build up on the walls of these radiators in our cars. This is probably a very good example of why phosphate free & distilled water is a good idea. I plan on cracking open this radiator once I get the new one.
