> why the system isn't clocking higher if the cooling system is running so comfortably. Because there's a upper limit on how much power (voltage, clock rate, etc) you can shove though a CPU before it starts malfunctioning or getting damaged by purely electrical effects, no matter how effectively it's cooled? It's entirely possible Apple has set the nominal limits fraudulently low for business reasons, but there are actual physical limits here, and depending on how the CPU is designed/optimized, it's quite possible that it's easy to build a cooling system that significantly exceeds what those limits allow to be demanded of it in a significant range of cases.
