Cut and soldered in the wires to the left side fan. Works great! Oriented the fan to pull air upwards. Heated a needle with a lighter to punch some slots in the housing for some small zip ties to secure the fan wires.
Extruder motor is around 45C in my enclosure now where it was near 60 before while printing PETG. Had some issues before with the extruder motor and heat creep to the bondtech gears causing the filament to soften then eventually slip and kill the print. Feeling confident now that that won't happen again.
