And with air conditioning included, you basically will have to double your power usage (it will emit 99% of the energy as heat, you will need equal amount of energy to cool that heat)

Isn't AC roughly 1/3 the energy again to remove the energy, not 100%?

And to the OP, if you limit the SP35 to 800W per PSU it is crazily quieter as the PSU's fans remain low @ 40C. Or 950W @ 36C, 1100W at 30C, 1200W at 26C. Your numbers might vary slightly as my temp readings may not be entirely accurate.

correct on both. AC power isnt 1:1 with the kw of heat, its generally 30-35% depending on efficiency of the AC and other factors

and i can attest to the second point. I just setup an SP30 (basically an SP35 / smaller PSUs) to run at 30-40% fans in the daytime (3.6TH/2kw) and ramp up to 80-90% (4.2TH/2.6kW) at nighttime when noone is around and power is cheaper.

at 40% fans are comparable to an Sp20 at ~30%
