    Default Refrigerant heatsinks

    Are there any refrigerant heatsinks where the refrigerant expands in the heatsink? i.e. not just liquid cooling but a full blown refrigerant system; I imagine -40 might be possible.

    Thanks, I was a little worried that I might be so far behind the times that people would rightly laugh at me.

    Yep, that is what I had in mind; perhaps with a riser to keep the CPU off the mother board, as it will soon become a block of ice.

    Yeah. Even with Peltiers, condensation becomes a factor.

    I wonder how well heatsinks with overhang fins would work without a fan (to pick up a lot of natural convection)

    That below with fan removed.

    There are some fanless designs like that; NoFan being the biggest name I can think of recently

    I am beginning to favor fans on the grounds that one can reduce temperature variations by making sure the fan hardly runs when the chip is idle; in this way one can reduce thermal fatigue.

    Small fan noise of varying speed can be VERY annoying. I put a big fanless heatsink on my first generation i7 once before big fan heatsinks (120mm+) were a thing (or at least before I knew about them). It was quiet, obviously, but otherwise it didn't work very well.
