Temperature inside a nuclear reactor: 300 degrees Celsius. [1]

Temperature on the surface of the sun: 5,600 degrees Celsius. [2]

Temperature of a CPU: ~75 degrees Celsius. [3]

not sure why you're being downvoted, but it's worth mentioning that the temperature is not what matters here but rather the heat generation per area. The temperature is a function of how quickly the heat can be pulled away as well as the heat generation.

> per unit area

A CPU is a lot smaller than both a nuclear reactor and the sun.
