I think this is approaching the most efficient build without extreme capacators. It could possibly be made slightly better by finding a way to produce the same amount of heat using less space by using the new power sources. I played around with it and either adding or removing a heat-outlet/4-vent unit lowers overall heat dissipation capability

Heating and thermal issues with power factor units

Reactors will operate at temperatures 40-70⁰C hotter than capacitors; therefore, it is essential to ensure that cooling air does not pass over a hot reactor, then flow over a cooler capacitor and heat it up. kVAr Solutions power factor trays and systems are designed to thermally isolate the reactors and have a separate cooling system from the rest of the equipment.

This PF figure then is a measurement factor for rating the "inefficiency" of the power transfer capabilites of the capacitor. For those capacitors where the PF figure is .1 ( 10%) or less, a ratio figure known as the "dissipation factor" (DF) is more commonly used. The reason for this usage of the DF figure is simply a convenience that takes
