if a cpu porfming at a specific speed (3.5 ghz for example) would it need the same watts (80 watts for example) to operate at this speed when the cpu tempeture rises? (just talking about the cpu)

thanks!!!
by any chance do you know any article o anything to prove the fact
It is in physics. Energy does not appear or disappear, it only changes forms. Your CPU does not do any mechanical (or any other considerable sort of) work.
Based on this, all the energy consumed by it becomes heat. Based on that, computation is a process of energy transformation but not an energy form by itself. In other words, computing is a way of transferring electrical energy into thermal energy. As a result, more/faster computations=more/faster energy transfer (but not a linear curve).
I am not sure if that is what you ask for but simply put - your computer is an electrical heater with variable heat output, where heat is the product and not the source.
While electrical properties of components do change with temperature, the components designed in a way to operate in a range of temperatures while maintaining electrical properties, and as long as you are staying within the design envelope, there should be no notable changes.
When it comes to specifics, you should refer to the design of the specific part and temperature-related graphs if you are trying to make a point.

CPU does not. CPU Fan Does.
All the power that is delivered to the CPU translates into heat, if it is not getting exhausted fast enough the temperature will rise. Just like water in the sink depends on the drain hole.
