i have a summit 100 amp alternator on my car. is this going to be enough to run my black magic electric fan i'm putting on?

It'll run the fan

question will be what will happen you have the radio blaring
lights on and a/c kicking.

If you have u/d pullies it will just make the problem worse at idle.

It's the "at idle amps" the alternator puts out that is key
100amp alternator probably puts 50amps at idle, maybe less with u/d pullies.
