    Active cooling isn't necessarily bad you just need to not overdo it with TDP. Passive cooling does force you to get good at this, i'll admit.

    Nothing is truly passive cooling. You're simply externalizing the work to something else. Here's an example:
    >Put a passively cooled device in a vacuum, wrapped in aluminum foil
    >run device
    >come back to molten plasma

      passive cooling means no moving parts

        The parts are very much moving though, it's what heat is defined as

          you are going to such extremes, that you live in a world where digital computers are considered analog because of varying voltages

            All I'm saying that methods of cooling are just varying degrees of power used, nothing fundamentally different. Using as little power as you needed is a good guiding principle, assigning any absolute values is not very useful.

          Maybe try passive autism instead of active autism.

      That's not an isolated system, so there will still be losses allowing it to reach an equilibrium before becoming plasma.

      Yet you posted a picture of a passively cooled device placed in a vacuum that's been functioning properly for billions of years while maintaining its specced operating temperature. Since conductive cooling is not possible in a vacuum, it relies entirely on radiant cooling. It's not an impossibility, it just requires engineering.

        Nothing passive about radiative cooling though. We're talking like 380 yottawatts being exerted to cool it down.

          All the energy it's making is being radiated, or its temperature would run away toward infinity. 380 yW is its TDP. Radiative cooling is completely passive and is viable if you have enough unobstructed surface area to keep the device at the desired temperature and don't place it so close to other devices that their radiated heat interfere with the cooling.

            Radiative cooling doesen't happen without externalities. It's surroundings are being heated up by equal amounts and moved around. Work is always equal, there's no free or passive anything

    nothing is passive and non-moving in the entire universe so its stupid to use that phrase when talking about heating and cooling

      passive cooling in this context simply means the media used to take heat away is not forced past the hot object
      namely it relies on radiative and/or natural convection
      think of it like taking a red hot ball of metal, and just placing it on a surface, no active components. it will cool through radiation, convection from the heating of surrounding air causing airflow due to the thermal differences, and also conduction through the surface it's placed on, the heat is moving, but that's not what active/passive cooling refers to

    Is the system doing work to carry out the cooling?
    Yes - active. No - passive.
    There, you can all go home now.

      Is a tractor driver making passive income plowing the fields? Next to a tractor they're doing practically no work

        No.
        You said yourself that they're doing work.

          A fan will make sound, it will move air and eventually heat up the room it's in. A farmer could do passive and active work, but the question is, do you count the driver's work as mainly active or passive?
