My temp gauge reads pretty hot sometimes... 230-ish, but it doesn't blow steam or puke coolant, so I've learned to live with it... and life is good.
3 row rad is a good thing, but is it wide enough? The more the radiator can hold, the cooler it'll run. If it's narrower than the support there are plates you can buy (I made mine) that go on either side of the radiator. Do you have a shroud? With the shroud and the plates, all the air in front of the car gets drawn through the radiator rather than sneaking around it.
Attached picture shows where they go.
