Fanless 0dB mini PC

The BFKK Quieter3Q 81E is a fanless barebone mini PC built around an Intel Celeron N5105 quad-core processor.

Check power and expansion needs

Verify that your PD power source supplies over 24W with a voltage range of 12V to 23V if you plan to use USB-C PD charging instead of the included 12V 2A adapter. The internal M.2 2280 slot accepts PCIe SSDs only and is not compatible with SATA drives. A micro SD slot allows additional storage up to 1TB.

Dual 4K display and VESA mount

Two HDMI ports each drive a 4K panel at 60Hz for dual-monitor setups. Connectivity includes WiFi 6 with MU-MIMO, Bluetooth 5.2 and Gigabit Ethernet for wired networks. The chassis measures 5.2 by 3.0 by 0.7 inches and includes a VESA bracket for mounting behind a display. BIOS options support Wake on LAN, PXE boot, Auto Power On and RTC Wake.

Questions about this item

Does the BFKK Quieter3Q 81E ship with a power supply and a VESA bracket, or must they be purchased separately?

The box includes a DC 12V/2A power adapter and a VESA mounting bracket; no extra purchase is needed for either item.

Should I choose the 8GB LPDDR4 / 128GB eMMC version or look for a larger capacity?

This model comes fixed at 8GB LPDDR4 RAM and 128GB eMMC; storage can be expanded later via Micro SD up to 1TB or an M.2 2280 PCIe SSD up to 5TB.

What does the dual HDMI 4K@60Hz spec mean when I connect two monitors to the N5105 mini PC?

Each HDMI port can drive a 4K display at 60 Hz simultaneously, giving you two independent 4K60 outputs from the integrated graphics.
