Design and Build
The defining characteristic of the MeLE Quieter 4C N150’s design is its complete lack of moving parts for cooling. By employing a fanless, passive cooling system, MeLE eliminates two common points of failure: fan motors and dust intake through ventilation grilles. This design choice is explicitly aimed at creating a quiet and stable computing environment suitable for 24/7 operation, such as in digital signage or home server applications. The compact, ultra-slim form factor is intended to fit discreetly into various setups, from behind a monitor to within a home theater cabinet.
However, this design comes with a significant thermal trade-off that the manufacturer openly discloses. The fanless mini PC will have a surface temperature ranging from 55°C to 70°C during heavy workloads. This is notably hotter than the case temperature of traditional fan-cooled systems but is stated to meet the International Electrotechnical Commission’s IEC62368-1:2018 safety standard. The chassis acts as a heatsink, dissipating heat directly into the surrounding air, which requires adequate ambient airflow for optimal operation.
Performance and Features
Processor and Memory
At the heart of the system is the Intel Celeron N150 processor, built on Intel’s newer architecture. This chip features 4 cores and 4 threads with a maximum turbo frequency of 3.6GHz and a low Thermal Design Power (TDP) of 8 watts. The low power consumption is a critical enabler for the fanless design. MeLE claims this processor delivers a performance boost over previous generations like the N5095 and N5105. The system memory is 16GB of LPDDR5x RAM, which offers high bandwidth. A key limitation is that this RAM is soldered onto the board and cannot be upgraded after purchase, capping the system at 16GB.
Storage and Expandability
The MeLE Quieter 4C N150 comes with a 512GB PCIe 3.0 x4 M.2 SSD pre-installed. A major flexibility point is that this internal SSD is user-replaceable. The M.2 2280 slot supports both NVMe and SATA M.2 SSDs, with a capacity of up to 4TB. For additional storage, a MicroSD card slot is provided, supporting cards up to 2TB in capacity. It is important to note that this MicroSD slot does not support booting an operating system and is not intended for high-speed PCIe storage expansion; it is for supplemental file storage.
Connectivity and Display
Connectivity is a strong suit for this mini PC. For wired networking, it includes a Gigabit Ethernet port. Wireless connectivity is handled by Wi-Fi 5 (802.11ac) supporting both 2.4GHz and 5GHz bands, alongside Bluetooth 5.1 for peripherals. The port selection includes two HDMI 2.0 ports and one full-function USB-C port. This USB-C port is particularly versatile, supporting Power Delivery (PD3.0) for charging the device, 4K video output, and high-speed data transfer simultaneously. The combination of these three ports allows the mini PC to drive three independent 4K displays at 60Hz, a notable feature for multi-tasking or digital signage.

Software and BIOS Features
The device ships with Windows 11 Pro pre-installed, providing a full-featured desktop operating system out of the box. The manufacturer also states support for alternative operating systems like Linux and Ubuntu. The BIOS offers several advanced features useful for deployment and remote management. These include support for PXE boot (and iPXE boot) for network-based operating system installation, Wake-on-LAN for remote power-on, and Auto Power On functionality. These features enhance its suitability for business or embedded use cases where remote administration is valuable.
Setup, Support and Ownership
Setup is designed to be straightforward, with Windows 11 Pro ready to go upon first boot. The use of a single USB-C port for both power and display can help reduce cable clutter on a desk. For those looking to upgrade, the primary avenue is storage replacement via the internal M.2 slot. The RAM is not upgradeable, and the MicroSD slot is for storage expansion only. The device is powered via USB-C PD3.0, requiring a power adapter that can deliver between 12V and 20V with a minimum of 36 watts. MeLE provides a one-year warranty for the product, with additional support details available from the manufacturer.

FAQs
Can I upgrade the RAM in the MeLE Quieter 4C N150?
No, the 16GB of LPDDR5x RAM is soldered directly onto the system’s motherboard. This means it cannot be removed or upgraded after purchase. The system’s memory capacity is fixed at 16GB for its entire lifespan.
How hot does the fanless design get, and is it safe?
According to the manufacturer, the surface temperature of the mini PC can reach between 55°C and 70°C (131°F to 158°F) during heavy processing loads. This is significantly warmer than most fan-cooled PCs. MeLE states that this operating temperature meets the IEC62368-1:2018 safety standard, but the device should be placed in a location with adequate air circulation and kept away from easily overheated materials.
Can I boot an operating system from the MicroSD card slot?
No, the MicroSD card slot does not support booting an operating system. Its function is solely for additional file storage, supporting cards up to 2TB in capacity. The primary boot device must be the internal M.2 SSD or an external drive connected via USB.
What power adapter do I need for this mini PC?
The MeLE Quieter 4C N150 uses USB-C Power Delivery (PD3.0) for its primary power input. It requires a power source that can deliver between 12 volts and 20 volts, with a minimum power output of 36 watts. A compatible USB-C PD charger meeting these specifications is needed; the device does not include a traditional barrel-style power jack.
