Strange possible fan relay overheating issue

I got a OBD2 scanner tool and drove the truck around for about 45 minutes of combined city and idle time. Ambient temps were about 85-90 degrees. Coolant temps were 210-212 at idle 216 cruising at about 50 MPH and 219 idling once I got home.
I have 3 questions.
Are these temps bad?
How likely is the high temps I was originally seeing are caused by a bad temp gauge in the dash?
If its not a bad gauge and I start to read OBD2 temps that are above 220, what would cause INTERMITTENT overheating?
I plan on replacing the water pump, thermostat and flushing the radiator anyways but I am just interested in understanding the problem more.

I got my from an ebay vendor for $250, plastic and aluminum - no complaints. Will Tillery has good used ones for $150.

would like to correct my previous post regarding temps with a OBDII reader..
ambiant temp about 85d (I know its not a hot day)
ran vehicle up too norm operating temp with a/c full blast at idle
obd2 temps were right at 180d and would drop to 175 when the tstat opened.
I have a 180d tstat
sorry for the poor information earlier
I will check it again while driving to work and post back

could you please post the link for that radiator? I am debating having my re-cored or just replacing. A '4 core' is interesting if that means the same as '4 row'.

So I monitored the temps via OBDII this morning on the way into work today
I have a 180d tstat - ambient temp was prolly 78d
results:
192d to 196d under load in rushhour traffic - pretty much never went below 192d
peaked at 205d going up a long hill
Link - here ya go
For Land Rover Range Rover Discovery Series 1&2 3.9L-4.2 4Row Aluminum Radiator
I know another user called them to ask why the price was $200 more then what I paid - they said they were out of stock for a few weeks.

pretty much direct fit -
you will need to grind a groove in the upper channel and grind down (not off) the upper tabs on the shroud, drill a hole for the upper brackets to connect to it
and make sure you get these fittings - the ones it comes with are junk
