I hear this is what the inside of those flock cameras contain.

The Thermolith!

[–] stupidcasey@lemmy.world 12 points 15 hours ago (7 children)

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 less 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.

That's the joke.

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?

[–] Buddahriffic@lemmy.world 8 points 14 hours ago (1 children)

My guess is that will only work until it saturates with heat. Some liquid cooling setups are also like that, where the rad isn't capable of dissipating heat fast enough to prevent the whole thing from overheating, but it'll work fine for a while because the loop itself can absorb a bunch of heat before it stops being able to take any more. Then they probably blame the chip maker for running too hot even with liquid cooling when their liquid cooling setup is actually less effective than the stock cooler or their case has horrible airflow and would choke any size or number of rads. But their reservoir acts as a heat buffer, so it takes 30 mins to even realize that, but they've already concluded it works.

[–] ZILtoid1991@lemmy.world 1 points 12 minutes ago

And sometimes that even would be a good strategy for cases where there's only short burst of higher heat output.

[–] ManaYoodSushai@feddit.org 63 points 23 hours ago (7 children)

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

[–] Hedup@lemmy.world 20 points 20 hours ago

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

[–] fartographer@lemmy.world 7 points 21 hours ago (1 children)

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

[–] jaybone@lemmy.zip 8 points 20 hours ago (1 children)

Just run a solid copper block for maximum efficiency.

We're talking about copper, dumdum.

Yes! The only way to increase the surface is to build a higher tower!

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.

[–] SolSerkonos@piefed.social 6 points 19 hours ago

Fanless cases are a thing, and they're neat.

[–] dejected_warp_core@lemmy.world 9 points 19 hours ago* (last edited 17 hours ago)

Weight, cost, and it's probably not effective for the long haul. The mass of a copper ingot like that will work like a heatsink, but it has a very low surface area for the energy it can absorb. So it'll heat up to a point that is uncomfortable for the CPU, then fail to radiate that energy out to the air effectively.

As a test-bench temporary heatsink, this is actually kind of inspired. No fans, to fussy clips, just stack a copper brick on the CPU, run some benchmarks, and then turn it all off.

[–] grue@lemmy.world 20 points 22 hours ago (6 children)

Do you have any idea how expensive a solid block of copper that big is?

[–] AnUnusualRelic@lemmy.world 20 points 21 hours ago

Would you even notice, after buying the ram and storage?

[–] Iconoclast@feddit.uk 21 points 22 hours ago (2 children)

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.

[–] tempest@lemmy.ca 13 points 20 hours ago

Cheaper than some noctua coolers.

Yes but you save on manufacturing.

[–] SolSerkonos@piefed.social 5 points 19 hours ago

Copper isn't that bad. It's not cheap exactly, but it's probably going to cost what an expensive CPU cooler already would.

[–] Successful_Try543@feddit.org 7 points 22 hours ago (1 children)

Despite the cost, it's damn heavy.

11 euro per kilogram

[–] pulsewidth@lemmy.world 7 points 23 hours ago (4 children)

Incredibly unwieldy. Real quick estimate of volume puts that at around 1.75kg of copper, so it wouldn't be possible to mount in a vertical PC case orientation (ie the majority of consumer PC cases) without significant (expensive) modifications to both the mobo socket mount and the case, else its weight would snap the motherboard, or just slowly flex it until traces failed.

It may not even be able to be used vertically like that for very long or it will compress and damage the CPU / socket / mobo. Just as an example, the weight limit of the thermal solution (HSF/water chamber heatsink/etc) for socket LGA 1700 is 950g.

This is a lot easier than running a line out to the swimming pool.

Am I blind? What's that card in the PCIE slot?

[–] Kayyy@lemmy.blahaj.zone 13 points 23 hours ago (1 children)

Looks like a PCIE to NVMe. You can see a short M.2 slot on the board, but that drive is wayyyy too big for it

This poor jpeg has aliased edges it's so scuffed. I can't tell if it's an old SSD, an old photo..or none of the above.
