Looks nice. Why they don’t sell PCs with cooling like that? What are the downsides?

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.

I’d also think moving your PC will rip your CPU right off the motherboard

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

Just run a solid copper block for maximum efficiency.

Wouldn’t gold be more efficient? Can’t I just fill my PC with gold doubloons? The rattling noise means it’s running.

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

So we need more copper?

Theoretically… Hell yes!

how long till it reaches thermal equilibrium? maybe it can endure a full load for an hour

I was wondering about this too, but I’m not an engineer so I would have to look up how to calculate this

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.

We’re talking about copper, dumdum.
