The fan is working fine

Then I would do a combustion gas leak test to see if you may have a blown head gasket.

You can get a cheap tester to confirm Click here Directions will come with tester but all you do is add dye and use devise to see if it changes colors.

It's also possible the water pump may have a loose impeller on it's shaft so flow would be reduced and it would run hot.

If engine runs at normal temp until you start driving either one of these things can make it over heat.

It would also overheat if engine fuel system has been turned up

Also make sure engine fan is on the correct way it needs to pull air from outside to engine not push out of radiator ( I have seen this done a few times)
