W124 300D 10 Degree Coolant Increase with A/C

Hey all,
Quick question. I'm in Central Florida. Coolant temp will run steadily at 80C no problems with out the A/C. When I utilize the A/C temps will run 90ish+. Sometimes hitting 100C when I'm really on the throttle. Will slightly rise with out A/C on.

I realize this is in the safe zone (normal zone).

I'm just curious about the A/C load condenser adding 10 degrees in front of the radiator. Is this pretty typical?

I'm getting 30 deg F temp drop from the A/C system. Both fans are working properly. Well low speed. Never gotten to 110 ish for the fans to come on high speed.

Just looking for opinions.
Thanks in advance.
