My truck builds heat at idle with the A/C on. The temp steadily rises to 210 at which point I lose my nerve and open the windows. Any engine speed above 1200 RPM resolves the situation and temps fall back below 200. Electric condenser fans run normally with A/C on (though frankly I'm not sure how effective they are at the age of 20 years).
I bought myself one of the fancy IR thermometers with the laser sight and last night took some readings of different areas of my radiator. This is what I found....
So, what next? Does this look like a radiator that is clogged or restricted, or a radiator that is doing its job?
