Do the cooling fans operate with the ac turned on?

Not talking about the fan behind the dash. Talking about the fans behind the radiator. Do the fans operate with the ac turned on??

Good. They must for A/C condenser or would only get cool moving along at some speed. BTW condenser alone can't be the overheating reason with you prior notations.
What ambient temps are you dealing with and do you feel heat being blow off both from fans when both warmed up engine, A/C on?
If cooling system is somehow marginally able A/C adds heat which is why it is fanned even before engine may need it.
Get codes but thing engine can't cool itself with any added heat and borderline now. List of maybe things but knock some questions off the list first,

step by step for a reason-
you say both fans come on when AC is on- yes
with engine cold coolant level is?
We next check codes - eliminate obvious - its free and fast - auto part stores do it FREE
You keep mentioning condenser WHAT makes that a suspect?
If it is not restricting air flow (leaves, dirt, ) and AC is not overcharged unlikely condenser.

Do as asked.
This so far isn't compressor - stop yourself from ideas that really can't be it. Think - if vehicle had no A/C ever engine has to stay cool and should on many shut down A/C several ways.
Lousy time of year for issues of course. Know overheating your ENGINE is at stake! That's worth attention! T
