      I would guess that the low surface area would lead to problems. At first it would cool very well because of the huge thermal mass, but once it reaches thermal equilibrium the cooling would be quite weak.

          The trick is not to move the PC, but rather the copper block, which just happens to have a PC attached to it.

          So, you’re saying that putting blocks of copper on everything in a PC will automatically shed unnecessary parts, building a more efficient system?

          You’re looking at about a half hour per kilogram of copper to raise it by 50 °C with 100W of heat.

          Actual delta from ambient to thermal limit will typically be a little higher than that, but so is processor wattage on mid-to-high performance CPUs, so I’m happy enough with that as a ballpark estimate.

          Someone else estimated that block as 4.5kg, so you’ve got something close to two and a half hours of cooling from an ambient start.

      Despite the size i would be very surprised if this was even equivalent to a moderate performing air cooler. The reason normal coolers have all the fins is for more surface area and youre able to easily and effectively push lots of air through, pullung heat off those surfaces.

      I have a micro ATX case that itself is the cooler. Heatpipes transport the heat to the case walls and they have fins to increase surface area. It can handle up to 65 watt CPUs.

      It’s not produced anymore. But with all the talk of the Gabecube I’ve been itching to make a new build with it. Unfortunately I have neither the money or the energy.

      Copper is actually ~25-250X leas efficient at transferring heat than a heat pipe and convection is hundreds of times more efficient than radiation at transferring heat and the fins on a heat sink would have hundreds of times more surface area for dissipating heat all that is to say this might work but it would be orders of magnitude less efficient than a standard heat sink.
