E28 M30 swap with modern electric fan issue

[rosebl]

I’m finishing an M30 swap on my 1986 E28 535i and noticed the coolant temp climbs slightly in stop-and-go traffic only when the A/C is running. I already replaced the radiator, thermostat, and fan clutch, but the issue still appears after about 20 minutes of driving. Has anyone tested a slim electric fan setup that actually keeps temps stable in hot weather without overloading the factory alternator? Ragdoll Hit

AC Solutions sells a condenser with an electric fan.

I've used SPAL fans with deleted mechanical fans.
No AC systems though which add a lot of heat load.
