You’re talking about heat (think ‘amperage’), where temperature is more like voltage.
You can’t get above a specific temperature merely by transferring more heat, or losing less heat, etc.
Upper bounds of temperature is still going to be limited by the temperature/frequency of the input energy, barring energy loss which can reduce it.
The solar atmosphere layers have specific maximum temperatures that limit the maximum temperature of objects exposed to them or the radiation from them.
