Once using RTX motherboard, you will enjoy extensive heat emission solutions and the benefit derives from its open structure.
It is foreseeable that, after the release of RTX, the wisdom of manufacturers and DIYers in heat emission solutions will definitely go far beyond your imagination, and there will be more system structures emerging in the market catering to users' needs. The size issue and intensive structures can easily get solved with RTX.
There is a typical design.
With RTX structure, the major heat source has been transferred from the internal to the external. Heat density inside this space is greatly eased and temperature budgets is well shrunk. While the CPU being in direct contact with exterior heatsink, the heat is emitted to the external space.
It is a vast difference as one is interior while the other is exterior.
General Considerations in System Thermal Design 
(see Blackboard)
In order to increase the total heat transfer from the heatsink we must increase on or more of the parameters.
In addition to selecting an optimun heatsink for cooling the processor, the whole system thermal designer must also consider the other components such as graphics cards, chipsets, memory chips, capacitors, drives.
There are the largest surface area and the lower ambient temperature in RTX design .
