The way mine is set up i sometimes think it gets a little hotter than I would like before the first fan kicks in, my engine usually runs in the low 80s.
I think in a hotter country I would run a slightly lower temp to keep the coolant a bit cooler, the thermostat will still regulate the engine temp via coolant flow.
