Correct me if I'm wrong but if the car is off, the only thing you're cooling is the fluid in the radiator which isn't helping you in any way.
I feel like an electric fan pulls enough current where I wouldn't want a little cheap toggle switch having to handle the load. Yeah they make 30a switches but most are pretty low under 10a I feel like. Especially if you get into led or random cheap switches vs something you'd buy in a racecar switch panel.
A relay basically isolates the switch so the switch has minimal current going through it and the relay does all the heavy lifting with the current. It's a switch for a switch. Now they can also be used for other things. Most relays are 5 pin which means one pin gives you bypass power when your switch is off.
I don't see the benefit of not adding one for anything over 10 amps
