Default Coolant fan question

I've got a different question about the fans. Do they both come on at the same time or are the sequential? I have only seen the driver's side fan come on when it gets hot. It cools everything down pretty quick by itself. Mine is also a 90 L98 convertible with an auto trans...

On my 86 with factory second fan runs sequential. Second fan comes on with A/C on or when temp reaches approx 225.
