2 fans wiring

now i have a 40 amp fuse and one fan working on it if i want to wire another fan should I have an individual fuse for each fan with 40 amp (the relay pinout is as follow 30 to the battery and have the 40 amp fuse 87 to the fan 86 to 12v switch 85 signal) or may I change the fuse to be 80 amp or leave every thing as it is and it will work? thanks for answering I just wanna understand because I'm confused

1 fuse and 1 relay per fan.

^^^ If you're considering staged fans - having them come on at different temperatures - you don't have an alternative.
