The time has finally come for Streacom to reveal the fruits of their collaborative labor with CALYOS in creating the SG10 fanless chassis. Though originally based on the NSG S0 (or NSG0), the entire project has undergone a complete redesign over the last few years to deliver the SG10 being shown off at Computex 2023. The new design is a 15 kg metal and glass monster featuring two of CALYOS' specially designed "Loop Heat Pipe" evaporation cooling systems that pull heat from the CPU and GPU, then passively radiate that heat away via two large condensers at the top of the chassis. The main body of the chassis is assembled from steel and extruded aluminium, and features tempered glass side panels. The front, rear, top, and bottom are all open to allow air to move through the chassis. The interior of the chassis uses a dynamic rail system, similar to Streacom's other case designs such as the DA2 and DB4, where adjustable brackets mount to structural rails running along the top and bottom of the chassis. The main components, such as an ATX motherboard and the GPU, are to be mounted to these rails in an X configuration on opposite sides of the chassis, facing each of the glass panels, while the power supply mounts to the floor of the chassis behind the motherboard. For drive support the chassis features an array of extra brackets with slots for screws to affix five 3.5" or 2.5" drives to. The front and optional rear I/O plates mount to the vertical steel structures and can be placed anywhere on those sides.

Streacom had a demo at their booth with the SG10 cooling a Core i9-13900K and GeForce RTX 4080 under a FurMark load with a total system power draw of around 680 W. While the RTX 4080 was sitting at a quite comfortable 75° C, the i9-13900K was stuck right up against its thermal limit of 100° C. Streacom claims the CPU and GPU loops of the cooler utilize identical designs with the only difference being the mounting bracket, however due to the GPU block being mounted directly to the GPU die the cooling is rated at 350 W rather than 250 W. They claim if the CPU loop is mounted direct-die it would perform similarly to the GPU loop, and it's possible to add 120 mm fans along the top, below the condensers, to further improve cooling. Another complication—not unlike with custom water cooling parts—is the GPU side of the cooler requires that mounting brackets and VRM/VRAM heatsinks be made to fit specific generations of cards. As such Streacom only advertises compatibility with the most recent generations of GeForce RTX 3000 and 4000 series, as well as Radeon RX 6000 and 7000, and only those which have a PCB shorter than 280 mm, but support is expected to improve with new bracket kits available after launch. The pricing has yet to be confirmed for the SG10 but it's rumored that it will land around the $1000 USD price point when it launches.

Noctua first teased their passive CPU cooler at Computex 2019 which weighed 1.5 kg and could handle processors with a TDP of 120 W passively and 180 W with quiet fans. Noctua had been planning to release a commercial version of the cooler in Q1 2021 but that date was pushed to Q2 2021 when Noctua updated its product roadmap in early 2021. Noctua has recently confirmed that this latest launch date is on schedule with an announcement that the cooler is "coming very soon" in response to a user on Twitter. The prototype featured mounting for AM4 and LGA 115x sockets with it keeping the Intel i9-9900K cool under load so we expect it will handle any consumer CPU.

First announced at Computex, MonsterLabo "The First" case was for sure a surprise in the world of fanless, passive cooling solutions. The original announcement is somewhat different from the final version of the case, which in fact will be available in two successive editions. The first one, B.1, will be a 100 (black only) units edition available on December 15th. The second one, B.2, will have 300 pieces that will be available in black and also white color at the beginning of 2019. The MonsterLabo "The First" will have a price tag of 429 euros.

MonsterLabo promises that its design can passively cool a high-end configuration with a Core i7-8700K (95W TDP) and a NVIDIA GeForce GTX 1080 (180 W TDP), although proper tests with intensive workloads will have to confirm that. The case includes a Noctua 140 mm fan (NT-A14), and has a steel housing measuring 205 x 215 x 420 mm (L x W x H) which weighs 7 kilograms.

Lacking its own booth at Computex this year, Thermalright displayed a few of its products in Nanoxia's booth, among them the previously teased HR-22 cooler, a massive monolithic heat sink meant to further the merits and virtues of its praised predecessor, the HR-02. Judging by the sheer size of the beast and the design choices evident in the pictures below (eight 6 mm heat pipes and an extended fin area when compared to the HR-02, a massive heat sink in its own right), one would expect the new HR-22 to compete for the top position among passive coolers.
