A Closer Look at the Metal Case

Design

The Pros

Overall, the main design of the case is quite good and effectively meets its intended purpose. The design concept hinges on the principle of heat convection, utilizing the upper cover that is equipped with built-in fins to promote the efficient dissipation of heat. This thoughtful incorporation not only enhances the aesthetic appeal of the case but also plays a vital role in maintaining optimal temperatures for the components housed within. Therefore, the combination of form and function in this design ultimately contributes to its overall effectiveness.

Interfaces/ports access

Users will be delighted to discover that the case’s interfaces and ports are fully accessible, eliminating the hassle of frequently unscrewing and opening the cover. The thoughtfully designed cutouts provide effortless access to all ports, enhancing convenience and usability.

The Cons

The circular cooling island, seamlessly integrated with the main cover, provides direct contact only with the primary RK3588S SoC. Unfortunately, other components, such as the memory chips, do not benefit from this cooling solution. To effectively cool these memory chips, it is advisable to employ copper shims that match the appropriate thickness and dimensions. For the remaining chips, including the USB controller and Ethernet chips, it is highly advised to consider using small copper heatsinks measuring 6 x 6 mm in size.

Mounting Brackets

One of the standouts features of this case kit is the inclusion of a pair of mounting brackets. These versatile brackets allow you to orient the case both horizontally and vertically on nearly any surface that has holes. They are securely attached to the case using four Phillips screws, making it incredibly convenient for wall mounting or situating the device in various industrial environments.

Installing the youyeetoo R1 Board

The R1 board comes in two distinct editions: the previous (older design) model with an M.2 2242 NVMe SSD/4G LTE socket, and the enhanced new V3.0 version, which has been replaced with an M.2 2280 form-factor socket, greatly increasing compatibility for mounting widely used 2280 type NVMe cards. The newer updated model also includes a few major improvements, for example, two USB 3.0 Type-A host ports, compared to the previous version, which offered one USB 2.0 port and one USB 3.0 port. Additionally, this metal case kit doesn’t come with any Wi-Fi wires or antennas. therefore, you’ll have to buy those separately, depending on the Wi-Fi/Bluetooth card you have installed in your M.2 E-key socket.

Assembling the Case with the R1 Board

The final outcome, illustrated in the photos below, exceeds all expectations, showcasing a well-crafted metal enclosure. For those interested, the Wi-Fi card and antennas can be purchased separately on the YouYouToo website. Furthermore, the images reveal that we have incorporated additional heat sinks onto the eMMC flash chip, USB controller, and Ethernet controller to improve cooling performance.

Measuring temperatures

Under typical non-intensive usage, you can expect the state of charge (SoC) temperatures to range between 33°C and 38°C. This is quite impressive, especially for a heating system that relies on passive cooling without a spinning fan.

Thermal Zone	Adapter	Temperature
npu_thermal-virtual-0	Virtual device	+33.3°C
center_thermal-virtual-0	Virtual device	+34.2°C
bigcore2_thermal-virtual-0	Virtual device	+33.3°C

The temperatures listed in the table were recorded at an ambient temperature of 20°C.

Stress testing

In this test, we utilized stress-ng in conjunction with lm-sensors to stress the hardware every 30 seconds between each assessment, escalating the CPU tasks from 1 to 8. As demonstrated in the table below, our maximum peak temperature readings ranged from 51.8°C to 57.3°C.
