If your question regarding fan relay amperage rating is because of concern over Spal fan, Spal fans will run with no issue with existing relays. I am running two Spal fans.
If anything, 120 amp alternator may be underpowered. I am running 200 amp rated Quality Power alternator. Quality Power high output alternator is newer generation Nippon Denso unit in custom CNC aluminum housing to work with CS144 mounting points.
