Calyos NSG-S0 100% Silent Fanless Gaming PC Review

Here are key points about the NSG-S0.


What's Hot


100% Silent: The Calyos NSG-S0 delivers on its fan-less 100% silent PC, but there is a very small sound you can only hear when everything in the room is turned off. You can actually hear the internal phase change liquid boil in the beginning until it reaches some level of equilibrium, it's actually kind of cool to hear physics in action, but you really have to try to hear it.



No Throttling: Under normal and heavy gaming conditions and different room temperatures, I wasn't able to detect any throttling. The NSG-S0's cooling apparatus can keep up with the cooling requirements of the system. I even saw a prototype on their website that cools an X99 CPU; I would assume you would only need a slightly larger CPU radiator.


Supports Wide Variety of Systems: While the 6700K and GTX 1080 are top-notch high-performance parts, it does seem that Calyos has plans to upgrade these components. You can also upgrade the 6700K to a 7700K by just unscrewing the block and reinstalling it like a water cooling block. Calyos also has plans for Intel HEDT systems, and perhaps down the road, even Ryzen.


No Bloatware: While the OS is just off the shelf, that can be a very good thing since you won't get any more software than what Microsoft provides.


What's Not


Heaviest PC I have Ever Reviewed: The NSG-S0 is the heaviest PC I have ever reviewed. The reason is because of its huge radiator system, which takes up more than 70% of the system's volume.


Riser Card Limits GPU to x8: While it's true that the GPU's riser card extension only reaches the second PCI-E slot that provides x8 PCI-E 3.0, the performance impact was unnoticeable. You can use a longer extension of a motherboard with an x16 slot closer to the GPU.



Final Thoughts


The Calyos NSG-S0 is a very nice high-performance gaming PC, and while you can feel it in your wallet, it is possibly the only production PC without any noise, fans, or electrical pumps. Calyos's technology is also being used in other categories such as the data center and even space exploration. It's a novel technology that relies on the physics of phase change, and a non-electrical pump to move the heat.




The NSG-S0 isn't the smallest PC, and it's definitely not the lightest. You won't be carrying it around town or to LAN parties, but it's perhaps one of the coolest gaming PCs I have ever reviewed. For those of you who want to use your own hardware, Calyos also offers the chassis separate, but I do recommend buying one of their pre-configured systems as they have tested the hardware to ensure it lives under the heat conditions under full load.


I have to say I am very impressed with the Calyos NSG-S0, it accomplished what some thought was impossible, and by doing so delivers a unique and impactful high-performance gaming PC.
