News Silent But Deadly: PC Chassis Can Dissipate 600W Without Fans

Toggle sidebar Toggle sidebar
Talk about Clickbait.
An article about the fact that a company say it is going to be showing a case, which it says will passively cool 600 watt.

What is next for TH?
An article about how the next CPU from Intel is going to be faster that their current offering and that it will have multiple cores.

It is a shame because in a not so distant past TH was a good place to go for articles, now it is just a waste of time at best.

so, is the reason that the actual case is not being shown to the public yet because it is that ugly or awkwardly designed?

Tom's earlier posted article regarding Streacom fanless cases shows an odd angle of one of their cases but nothing i can find anywhere with a full view of this SG10.

Streacom and CALYOS Tease the Unfashionably Late and Beleaguered SG10 for Computex 2023

Streacom have announced that they'll be hosting a booth at Computex with CALYOS, where they'll be showing the fruits of their labors on the long awaited SG10 passive-cooled chassis. If you're unfamiliar with the story of the SG10: back in late 2016 CALYOS made waves in the tech sphere with a...

Hi,

This case is from the Kickstater project 'Calyos NSG S0' (2017 !)
As the Kistarter project itself doesn't reach production, the project has been reshape and after consulting the Kickstarter community, Calyos make a new derived project with Streacom.
The phase changing system used by Calyos do dissipates about 300W per loop, so yes, 600 W with 2 loops.
It is a proven technology already on the market for data centres and spatial applications, not available for general consumer until ... now.
But, well, do expect a premium price for this solution.

Have a nice day.

Company issues a press release, the tech press picks up on it and reports it. What's so fishy about that? They cover product announcements all the time, in addition to their own product reviews and tradeshow coverage. It's all part of the mix.

I can see that you might not have picked up on their habit of highlighting when they do an actual review or roundup - those articles tend to use those words in the title. For myself, when I clicked on the article, I did not expect to see a full review and therefor do not register this article as clickbait.

Perhaps it would've been better if they'd included the word "Claims" or "Announces" in the title?

I'm interested to know just how silent this ends up being. Heatpipes tend to produce a sizzling or popping noise, under high heat, because they function by boiling the working fluid at the hot end.

I guess you can probably find reviews of existing Streacom chassis. I was never that interested, because they tend to be pretty big and expensive, for the amount of heat they dissipate.
 
Also, seems like choosing an AM5 7950X3D instead of a 13900k would mean you could go with a more powerful GPU, as well. I know there are people who love silent hardware and might like this--it doesn't interest me, however. If the top is open-air as shown, then heat dissipation might actually increase. The images seemed to show differing configurations.
 
I've always loved the idea of using the massive surface area of the PC case as the heatsink - but the issue always falls to how do you efficiently get the heat from the CPU and GPU to the outer case. Have to come up with a new form factor where you can mount the motherboard CPU-down face-first into the side of the case. Maybe strip off the GPU's heatsink and use a riser cable to smoosh it face down into the other side of the case.

It's going to take a big, jointed effort to make this idea work.

these passive cases for huge thermal capacity are never "pretty".

theres just a massive amount of metal heatsink to dissipate the heat. (and that much metal isnt gonna be pretty)

Or cheap. This is gonna be EXPENSIVE, probably way more than just getting a budget case and fans.
Probably weighs a ton as well

I know it's not quite what you mean, but I've always been partial to (non-windowed) aluminum cases. Good air circulation can transfer a certain amount of heat into the case, and aluminum is a significantly better heat conductor than steel (but not as good as copper).

If you look at Streacom's other cases, they accomplish this with heatpipes. It seems to work alright. There was an article, a couple weeks ago, where someone used a solid block of copper (yes, I know that's not as good a thermal conductor), which I speculate might've been to avoid the noise that heatpipes can produce.

I think your idea is interesting, though. Like, what if the CPU were on the bottom of the motherboard. Instead of having a motherboard tray, you bolt the other sidepanel directly into the motherboard, and it just stays mounted there. That way, your access to the other motherboard slots and components is unimpeded.

The only reason to deal with the cost and trouble of dissipating a significant amount of power through passive cooling is if active convection cooling isn't an option.

Some situations are very noise sensitive, like recording studios or perhaps certain scientific applications. In other scenarios, the issue is dust and debris that would clog up a PC reliant on convection cooling.

For everyone else, air or water cooling remain better options. This case is for a specific market niche.

It says fanless but doesn't say passive. I'd expect a liquid to transfer the heat to the case panels which would then passively remove the heat without needing fans. The tubes can be flexible and allow quick disconnects to remove the case panels completely if needed.
That's how I'd do it.

The article says:

"The case was developed in collaboration with Calyos, which specializes on advanced thermal solutions relying on loop heat pipe (LHP) technology."
​

Liquid cooling requires a pump, which would seem to partly defeat the point of being fanless. More importantly, to efficiently cool the water, you need a proper radiator. To remove 600 W of heat from a reasonable-sized radiator, I'd imagine you'd need fans.

The way heat pipes work is by boiling a working fluid, which condenses at the cool end and returns to the hot part via capillary action. The amount of energy required to boil the fluid makes them incredibly efficient. Better yet, the only energy source they need is the heat they're intended to cool.
 
This was inevitable, as the desire for quieter custom PCs motivates system builders to make all kinds of creative choices in fan selections and placement, sound dampening, PC tower placement, noise-cancelling headsets, and so on. There's the PC build (Linus, I think?) that used an antique home heating radiator to fanlessly cool a gaming PC, which was hilarious but also would make for a great conversation piece and a novel way to really make a PC special. We occasionally see mid-tier GPUs with silent cooling solutions, and PC heatsinks as well.

Almost never do we see realistic ways for the average gaming PC builder to fanlessly cool a reasonably powerful gaming PC, though. I do remember the prototype article on Tom's from a couple years back. Glad a similar solution is finally making its way to the market. I will buy this, or something like it, for my next build in a few years' time.

Heat dissipation (LTT video link) is sufficient, as long as your surface area is! Same way space stations cool themselves in the vacuum of space, where fans would be pointless as there's essentially no gas for them to move over heat dissipation fins. Heat radiates away from its source towards areas where there's less heat energy - but fans would definitely be quicker here on earth. Given the huge surface area of a case like this, I could see how this would be sufficient to dissipate 600W without fans. Wonder how warm the surface of the PC gets?

Pumps are not fans.

Yeah, literally nobody needed that clarification. Pumps make noise (thus partially defeating the point of a fanless chassis) and liquid cooling doesn't usually work well enough to dissipate 600 W without fans.

Just for yucks, I did a quick search and found this example of water cooling without fans (except for the PSU):
​

To paraphrase Linus:
​
"... $1200 of water cooling hardware ... the equivalent of 18x 120 mm radiators ..."​
​

And it kinda looks to me like he's slightly cheating by having his case half-open.

As for the case in the article, it's clear enough that it isn't using fans or pumps. And based on the price of other Streacom cases, I'll go out on a limb and say I doubt it costs more than half of even just the water cooling hardware in Linus' setup, plus you don't even have pump noise.
