I have just been put to shame. You've got at least double my setup, but in knowing the heat challenges and power needs, that is one amazing setup. I don't see that fan as still clearing all the heat, what's your normal room temp (I run in the 90F-95F with using 26,000 watts). Also, what's your main panel? I've only got 3 phase 400 amps, I'm guessing you have a lot more.
