Streacom has announced that its new monster passively-cooled PC chassis is almost ready for purchase. Shipments of the new case will ship as soon as May 2024.

I don't consider that a heat pipe. If it's a closed-loop and includes a pump, then it's really just a phase-change cooling system like air conditioners use.

It would be interesting to hear more about the "patented solid-state capillary pump".

As for the open front & back, you'd better hope there's no coil whine from the CPU motherboard, GPU, or PSU.

Seems like the top must be open, too. Looks like a bit of a dust trap, though obviously not as bad as if you had active airflow.

Here are pics from the CES 2023 article. IMO, they should've been included in this article - otherwise, it's hard to appreciate what they mean about the motherboard and GPU being angled.

Also, that gives a sense of scale. Seems pretty huge, with that guy standing next to it.

I really like this concept as it's the first passive cooling design I've seen that can cool a lot but doesn't weigh a ton (16kg). They do split the CPU (250W) and GPU (350W) so while it's 600W I feel like that's an important distinction. I don't think I could ever justify the cost (maybe lottery or other windfall!) but it's really fascinating just the same.

It's a loop heat pipe which I had to look up when it was covered at Computex because I didn't know the terminology and it had seemed like it was just a closed loop to me.

Unless someone cuts open the evaporator I doubt we'll find out much more. I couldn't find the patent information from Calyos, but they have this on their website: https://www.calyos-tm.com/technologies/loop-heat-pipes

Definitely a big concern since you'd most likely want this case on display. It should be fairly avoidable on the CPU/PSU side as generally you can buy your way out there barring some failed design. I'd be pretty worried about video card though because coil whine seems really random to the point where you wouldn't know until you had it.

So it's basically mid tower height, between a mid tower and dual chamber width and full tower depth.

The nice thing about these cases, is that with 2x simple 140 to 180mm, 12V case fans running at 5V, you can increase the cooling capabilities by at least another 300 to 500W.

Okay, if the "pump" is a completely passive structure, then perhaps I stand corrected. I still think not accurate to call it a "heat pipe", as that implies 2-directional flow. I'd rather call it a "passive, phase-change heat loop".

So it's basically mid tower height, between a mid tower and dual chamber width and full tower depth.

An example of a small mid-tower case is: 451 x 431 x 197 (without feet or protrusions). Compared to that, it's 34% longer, 20% taller, 36% wider. I expect it would give the impression of a large mid-tower case. Where they seem to save space vs. a conventional case is by eliminating the drive cage (as far as I can see). With a drive cage, I do believe it'd be huge.

BTW, I'd be a little concerned about SSD temperatures. A decent PCIe 4.0 NVMe drive can crank out a fair amount of heat. You'd want to put something in it that's on the efficient end of the spectrum, and then mount a big, passive heatsink on it.

Supports 3x 3.5 or 6x 2.5 (is expandable) and from the pictures they seem to have brackets which mount in the bottom.

You wouldn't necessarily need anything efficient, but you'd absolutely need a big heatsink on it. @Albert.Thomas has tested a bunch of SSD heatsinks over here https://www.boringtextreviews.com/ which is a great resource for them.

I knew this thing looked familiar

Oh, and I forgot about the sizzling noise from the heat loop, itself. As the working fluid boils, it tends to make a bit of noise.

I knew a guy who had a fanless notebook PC. He got it with the hope it'd be perfectly silent. Instead, what you'd hear was fizzling and popping from within the heat pipes.

 

[Albert.Thomas]

I would love to test something like this.

I really like Cooler Master's Cooling X Pre-built, which is somewhat similar, but it's a pre-built with a $7000 price tag

Just keep in mind that these tests are done under extreme workloads. For common users just loading basic apps and gaming, even the most basic heatsinks will be fine. Only folks who run storage intensive workloads will have need of a strong heatsink.
