try some of that water wetter in your coolant, u also have a 82 degree thermostat?

mine runs very cool but i have a GRS though, when i first installed it mine run too hot and my wires were the wrong way

i have twin 10" kenlowes, cant remember which way mine spins though,

do u have to run that shield thing on the side of the i/c? that must be stopping air getting through surely
