109F, idling, and gauge at 3/4 doesn't sound too bad. Which direction was the nose pointed relative to the wind? It would be interesting to pin down the conditions where these things are getting hot. I was at the Hummer Happening near Los Angeles in the Santa Monica Mountains, and temps were low 90's. I was watching the guage closely, because of the overheating reports. One minute the guage was just below the red zone, and the next it was mid-point, even when just idling with the air on. Seems like something isn't quite right.

The "good old days" when you could hang a side of beef in your car.... Oh well I guess DuPont made out on the R12 to 134 switch.... Just joking I know why the EPA made us switch and A/C in newer cars actually works pretty well, in fact one of the things I like about the H3 is how well the A/C works. I'm sure the relatively low heat load due to the small glass area helps.
Interesting question about the wind direction.
The other day when it was 109 and the gauge stopped at about 3/4 (I agree 3/4 on the gauge is not a concern) the wind was blowing about 5 to 10 mph and was hitting the vehicle on the drivers front (i.e. if the H3 was facing north the wind was coming from the north west). Today the temp was about 107 and there was no wind. After idling for about 10 min the gauge was past 3/4 which was surprising until I read your e mail. Just for fun I'm going to have the guys in the shop throw a 14" Spal fan on it and see what happens.
