I have an idea for cooling 1kW GPU power.

[tugrul_LordOfDrinks]

• Power is plugged to 2 isolated heat pipes and directly go from psu to graphics card instead of meltable cables and have non-conductive coolant fluid on PSU-end pushed inside of the 2 pipes so they are cooled from inside.
• The pc case is made of heatsink.
• Outer surface of pc has heatspreader fins everywhere
• The hull is made of heatpipes (copper)
• Each one of the 24 heat-pipes end at the PCIE port with a docking port
• 3 heat pipes going right at each face of cube (as pc case), making 24 pipes total. With dedicated spreading per face so whole surface of case is utilized with minimal temperature gradient between them.
• The docking port of heatpipes perfectly match the gpu's heatspreader pipes
• The docking port is surrounded by silent fans pulling air and pushing outwards
• The only air intake of pc case is through a narrow window right in front of docking port (cold air first touches the port)
• Docking port is also strong and carries the card weight
• The VRAM deck is isolated from the heat pipes and dipped into a coolant tank of the pc case. The coolant is made of non-conductive mineral fluid and pass through the pcb without touching heat pipes.
• VRAM/PCB coolant fluid is circulated through 1/10 of surface area of pc case and has 1 dedicated silent fan outside.
• The PC case also has a robot arm to grip RAM modules on motherboard. The grip surface is made of peltier coolers rated at 20W cooling power so RAM are always cool too, with temperature sensors.

The pc case has Aliens theme decorations on inner surface as if each heatpipe looks like an alien hive corridor. The outer hull looks like a space ship of the Predator. Name of this pc case would be AvP.

But why. 600W already leads to molten cables and missing rops. Lets just not go there ok

Is it made of 24 heatsinks with whole outer surface of case made of fins? Do the heat pipes go through whole pc surface? Does it have coolant tank for PCB? Does it carry the weight of card? Where are the power conductor pipes from card to psu?

I said, the idea - not the execution.

 

[tugrul_LordOfDrinks]

From the looks it is only using 1/8 of case surface to transfer the heat from gpu. What I meant is 24 pipes, going towards 3D, all faces of a cube directly, not from single direction like that, but 3 pipes per direction so whole surface is balanced.

Sure, it can be improved. But like I said, the idea isn't new.

 

[xtreemchaos]

yes the idea has been on going for a long time, and it looks good untill everything gets heat soaked, id love to see it work but every increasing heat wins in the end unless you can chuck loads of cool air at it but that defeating the object sort of.

 

[droopyRO]

Also 1KW of energy would make the room it is in hot as the desert + whatever else that PC consumes another 150-200W at least.
I can feel the room warming up in the winter, with a 200W GPU and a i5.

 

[Jacky_BEL]

Add in a 99+ certfied PSU and superconductive wiring.
The GPU could be external , connected via a quantum-bus.

At the end of the day, the gpu might be cooler, but your room will still be 1kw hotter

Could see something this absurdly complex, for scientific equipment. Maybe, even a lab-task appliance that must be single GPU, but as fast as possible?

My 'over the top' idea is a bit more 'self-contained'.

• GPU PCB is hermetically sealed (centrally) within a 2-slot 'tank'. 'block' on GPU die gets coolant flow, first.
• PCIe fingers are connected similar to the 5090FE, through the enclosure. Power inputs are at the 'end' of the card.
• GPU remains submerged in white oil (active pump) or fluorinert (phase-change percolation), QD-(dis)connected to 240mm+ radiator.

Alternatively, I've pondered about a hybrid liquid cooling solution, where only the GPU die gets direct watercooling, but the rest of the card is immersed in oil, and passively expells heat through the finned (sealed) casement.

Basically, take a SXM-style GPUboard, put it inside a cast and milled 2-piece (gasket-sealed) enclosure, with all the PCIe, power, and display outputs engineered into the casement.

Custom loop. Way easier.

I thought about trying to explain the parts of this that wouldn't work, like heat pipes are not "heat pipes" if they have pumped fluid, Peltiers are horribly inefficient as cooling devices (a lot more heat is generated to cool), heat pipes have to be heated to force the evaporation/condensation cycle so just randomly placing them about doesn't do what you think it will, but I also assume that the the grammar and explanations may just be unclear enough that I'm not getting the full idea(s) so...

maybe this would go much smoother if you'd just draw me a picture.

For some applications, 'stacking' inefficient cooling methods, still ends up being 'the best, for task'.

Back in the 'fun' days of PC Enthusiasm, it used to be pretty common to stack TECs atop a AthlonXP, etc.
Sure, a phase-change loop, staged WCing+chiller, or an 'evaporative cooler' would perform better, and be much more efficient but, it was an affordable way to get into sub-ambient cooling, back then.

Today still, we see TECs used where bulkier active heatpumping technology is not applicable but the need remains.
For instance, a lot of high-speed Ethernet transceivers, etc. use tiny stacks of TECs to keep extremely thermally-dense ICs cool.

Don't get me wrong, I use TECs every day at work, they're great. They're just not efficient and people don't tend to realize that not only do you need to apply power to them to cool things, but that power translates to extra heat to dissipate somewhere. A common situation is double the heat (unless your dT is close to zero, but that's unlikely)... So if you for example are cooling 50W and your hot side is 30 degrees warmer than the cold side, you can assume you'll likely have at least 50W of heat added by the Peltier. So now you have to dissipate 100W into the environment. We use them for temperature control, i.e. with a specific control set-point. So we set 25C for example and no matter how much the load tries to heat up, the Peltier will keep it at 25C via a PID loop temperature controller (and thermistor). If you have a bidirectional controller, you can also keep that thermistor at 25C if the ambient Temps drop below 25.

Also, it sounds like this probably isn't new info to you, I was just sharing for the rest of the thread lol

100%

If one (or an AIB) was going through all this engineering to try and semi-passively cool 1KW of compute, that heat is going to (have to) be contained within air/water, and carried away and out of the workspace.

Biggest benefits I've observed in 'extreme DIY cooling', is moving the heat out of the room. Either, through direct exchange (geothermal cooling) or simply expelling waste heat(ed air) out of a window.

 

[Onasi]

The only place a 1000W anything belongs in is the properly setup server rack. Even then, it would be questionable in terms of efficiency. A 1000W consumer GPU WOULD require an insane setup like what the OP described which automatically would make it absolutely unusable for any sane person. Frankly, the 5090 is already pushing it.

That’s the main ticket. Actually being in a room where a 1000W GPU works without redirecting heat out of it would be torturous.

Custom loop. Way easier.

Yussss, nothing maxes out e-peen and minimizes temps like planning out, picking up, and executing a killer custom loop. With enough rads/flow rate you could def keep a 1000W GPU in check in a standard full size ATX case. Albeit at the expense of a very warm room.

Large e-peen is just a bonus but planning and putting up a loop is always hella comfy ^_^

so basically, forged from the bones of copper, a thermally optimised SCI-FI horror messiah!! That too with a single robotic arm to operate our memories. Are you cooling a GPU or setting the stage to wipe out mankind lol This and a dose of AI and its GAME OVER!

I prefer the more traditional method:

This with the addition of routing the exhaust via duct or pipe and out of the window - say hello to 1kW all day long!

In all seriousness, this is basically how many serverfarms/datacenters do it.
Tons of loud airflow, in-unit. Large swamp coolers and/or active heatpumps then pump that heat outdoors.

Or how about this, we can set it up like an AC with an indoor unit and an outdoor unit. Put the PC with the 1000W heater outside and route the display and peripheral cables inside, and you're good to go!
