High power OEM fans are available that draw 30A~, a stock SR alternator is 80A

A simple quest alternator upgrade gives you 125A, thats an EXTRA 55A, I'd like to know where all that extra power is going, that the ignition system wont be able to use, since I really really, reallllyy doubt the 30A fan draw (at max, and only once in a while if you've actually set this up properly), is somehow surpassing 55 amps..
