Castle - Make A Special Edition Monster

[lutach]

A question for the engineers out there . Would it make sense to have a lot of MOSFET (Lets say a FET driver already was chosen and powerful enough to drive close to 300 FETs) on a controller to make each MOSFET work less to provide the power some of us need? Lets say I have a design for a controller with 240 MOSFET total, 80 per board, would it actually run cooler because there will be less load for each MOSFET? The reason for this is I see a few controllers with less FET that actually run a bit hot, but a controller with the same spec (AMP rating wise) with more FETs will actually run cooler. One example is one of my 30A old Kontronik controller runs cooler then some of the latest 35A controllers.
