Atlast! Solutions presents silent mini PC powered by Intel's 10-core i9-10900T CPUs

Unlike the usual fanless mini PCs that are restricted to ULV processors, the Atlast! Sigao Model B includes a desktop-grade Intel Core i9-10900T CPU coupled with up to 64 GB of DDR4-2666 RAM and NVMe storage solutions like Samsung's 970 EVO SSDs, which are notorious for high temperatures in full load. These components can get quite hot without proper ventilation, but the Atlast! passive cooling solution still manages to keep internal temperatures at around 46 degrees C, even without a venting system.

Silent PCs usually come in the form of palm-sized models that are powered by entry-level ULV processors, or quite robust builds featuring inaesthetic chassis covered by heatsink fins that are still restricted to lower-TDP chips. Fitting more powerful components in something that would pass as a mini PC chassis is quite the tricky feat, especially when trying to keep active cooling out of the equation, but it is not impossible. Atlast! Solutions proves this with its latest Sigao Model B compact PC that is completely silent, yet still powered by Intel’s Comet Lake-S i9-10900T CPU.

For the Sigao Model B mini PCs, Atlast! opted to go with the latest fanless chassis produced in Germany, which do not include any air vents. These systems integrate an Asus H470-I Mini-ITX mobo and, although the i9-10900T CPU is rated for 35 W TDP, it can easily go above when all 10 cores are operating at 4.6 GHz. Without properly ventilated cases, the included Samsung 970 EVO NVMe SSD with up to 2 TB capacity plus the dual 2.5-inch SSD/HDD solutions could get quite hot. However, Atlast! claims that the Sigao Model B is able to keep full load case temperatures at around 45-46 degrees C.

The compact nature of the chassis does not, unfortunately, allow for the inclusion of a dGPU, so users will be forced to rely on the UHD Graphics 630 iGPU. Nevertheless, the Asus mobo could get Rocket Lake-S support with a BIOS update, so users may eventually be able to upgrade to an i9-11900T CPU with UHD Graphics Xe 750. Maximum RAM capacity is 64 GB, but the speed is limited to DDR4-2666. Motherboard connectors include triple video outputs ( DP, HDMI, USB-C 3.2 Gen 2), a USB-A 3.2 Gen 2, 4x USB-A 3.2 Gen 1, 2x GbE jacks, 5.1 sound jacks, plus support for Wi-Fi 6 and Bluetooth 5.1. Also included inside the chassis is a 200 W PSU.

Starting prices are quite high, but probably justified since these are built-to-order systems. An i9-10900T coupled with 16 GB of RAM and only a 250 GB SSD costs ~$2,300, while a model with maxed-out specs would set you back ~$3,500.

I first stepped into the wondrous IT&C world when I was around seven years old. I was instantly fascinated by computerized graphics, whether they were from games or 3D applications like 3D Max. I'm also an avid reader of science fiction, an astrophysics aficionado, and a crypto geek. I started writing PC-related articles for Softpedia and a few blogs back in 2006. I joined the Notebookcheck team in the summer of 2017 and am currently a senior tech writer mostly covering processor, GPU, and laptop news.
