Twin 16" fans? They will move a ton of air. I've always used Spal 16" single fans on my LS swaps. No AC though. A typical 16" Spal draws about 35 amps on start up and then once its spinning its less. Don't how much less but the start always draws the most amps. Relays "good" ones like Hella are water resistant. The cheap auto store relays not so much. The two Hella relays on my LS swapped Jeep TJ (fuel and fan) have been under the hood for 12 years thru rain and snow with zero failures.
Good luck finding the solution and keep us in the loop.
