I understand you have questions in regard to Intel® Turbo Boost Technology, let me help on this matter.
Since ESXi has been developed for server platforms, I assume your current configuration is based on server computers.
1. The Intel® Turbo Boost Technology works depending on the workload of the processor, whenever the program requires speeding up the processor speed it will throttle to the maximum allowed.
2. This is the same answer as the previous response.
3. We think you have a server environment and this will required especial cooling equipment but the technology does not work just when the processor reaches maximum processor temperature. You can check maximum temperature at https://ark.intel.com/
4. It does not work of power limits or temperatures. This will work depending on the processor workload. Please see the information that was linked previously.
Hope it works.
