System: Kernel: 5.15.0-33-generic x86_64 bits: 64 Console: pty pts/1 Distro: Ubuntu 22.04 LTS (Jammy Jellyfish) Similar to other Jasper Lake mini PCs the iGPU showed limited details in HWiNFO and was unknown to GPU-Z: The Mele Quieter3C is a compact fanless mini PC measuring just 18.5mm x 81mm x 131mm and powered by a Quad Core Celeron Jasper Lake N5105 with TDP 8W supported by 8GB Single Channel LPDDR4 and equipped with an single eMMC 128GB although the barebones system does not include a SSD. Connectivity is provided by support for Bluetooth 5.2 WiFi 6 (802.11ax) MU-MIMO and wired via the integrated Gigabit Ethernet port. resources: iomemory:600-5ff iomemory:400-3ff irq:135 memory:6000000000-6000ffffff memory:4000000000-400fffffff ioport:4000(size=64) memory:c0000-dffff

During the stress test, the maximum temperature I recorded on the top of the device was around 55.6°C at an ambient room temperature of 14.1°C with the device not being too hot to touch. Networking (Ethernet and WiFi) If the CPU frequency is monitored during the stress test, it can be seen that the initial temperature peak is caused by the CPU running at an average of 2800 MHz for the ‘PL1’ duration after which it power throttles and drops to an average frequency of 2620 MHz:

Features of the Mele Quieter3C mini PC

WiFi 6, Bluetooth5.2, Gigabit Ethernet and HDMI，supports 4K@60fps HDR videos dual-screen outputs, 3xUSB 3.2 ports, 1xType-C. The Quieter3Q offers a notable improvement over its predecessor. Whilst the physical appearance and external port configuration are similar, both the CPU and iGPU are more powerful and the M.2 NVMe slot is now PCIe Gen 3 rather than Gen 2 resulting in a doubling of bandwidth which is significant when you only get two lanes. Highlights B . Press the power button and press F7 or Delete continuously to enter into select boot device menu. Select your USB flash disk to install Ubuntu. I got the Quieter3 to optimize size/weight for mounting on the scope. Time will tell if it was a viable choice. Earlier Atom-based units were just too slow, these newer models seem to have finally crossed the threshold to practical performance.

Since I have a 3Q don’t have to worry about PD, just need 12 V. These also work: The power figures fluctuate so the value is the average of the median high and median low power readings. UEFI (BIOS) Powering up the mini PC and hitting the F7 key results in a boot menu that includes access to the BIOS which is unrestricted. Final Observations During the stress test, the maximum temperature I recorded on the top of the device was around 67.1°C in an ambient room temperature of 17.0°C, and although the device was not too hot to touch this is some 10°C hotter than the Quieter3Q and Quieter3C. Networking (Ethernet and Wi-Fi) When reviewing mini PCs, I typically look at their performance under both Windows and Linux (Ubuntu) and compare them against some of the more recently released mini PCs. I now review using Windows 11 version 21H2 and Ubuntu 22.04 LTS. I test with a selection of commonly used Windows benchmarks and/or equivalents for Linux together with Thomas Kaiser’s ‘sbc-bench’ which is a small set of different CPU performance tests focusing on server performance when run on Ubuntu. I also use ‘Phoronix Test Suite’ version 10.8.3 and benchmark with the same set of tests on both Windows and Ubuntu for comparison purposes. On Ubuntu, I also compile the v5.15 Linux kernel using the default config as a test of performance using a real-world scenario.
