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.
Heat pipes are fucking magic and you can’t convince me otherwise

Looks nice. Why they don’t sell PCs with cooling like that? What are the downsides?
Do you have any idea how expensive a solid block of copper that big is?
Yes but you save on manufacturing.
Would you even notice, after buying the ram and storage?
If that block is roughly 4.5cm x 4.5cm x 25cm then the volume of it is about 500cm³ which translates to 4.5kg of copper. At 11€/kg that makes about 50 euros.
Cheaper than some noctua coolers.
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.
So we need more copper?
I’d also think moving your PC will rip your CPU right off the motherboard
The trick is not to move the PC, but rather the copper block, which just happens to have a PC attached to it.
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.
Why copper? Aluminum works way better as a dissipation surface.
Copper has more mass, heat capacity, and thermal conductivity per litre.
Is aluminium actually more effective as a dissipation surface? I hadn’t heard that.
Copper is better conductor but it’s worse at dissipation. Do the experience yourself, heat a block of each and then touch them afterwards.
Is that not because the copper holds more heat, so stays hot for longer at the same dissipation?
