Silent fanless mini PC for office and media

The BFKK Quieter3Q uses a passive heat sink instead of a fan to deliver completely silent operation at 0dB. It is built around an Intel Celeron N5105 quad-core processor with 16GB of LPDDR4 memory and ships with Windows 11 Pro installed. The compact chassis measures 5.2 by 3.0 by 0.7 inches and includes a VESA bracket for mounting behind a display.

Dual 4K display outputs and portable power

Two HDMI ports each drive a 4K panel at 60Hz, enabling a dual-monitor setup without extra adapters. Connectivity includes WiFi 6 with MU-MIMO, Bluetooth 5.2, and a Gigabit Ethernet port for wired networks. A USB-C port accepts USB PD 3.0 input from 12V to 23V sources over 24W, so the unit can run from a power bank or car adapter as well as the supplied 12V 2A adapter.

Expandable storage under sustained loads

The system provides 256GB of eMMC storage plus a 256GB M.2 2280 PCIe SSD, with the M.2 slot supporting PCIe drives up to 5TB and a micro SD slot for cards up to 1TB. SATA M.2 drives are not compatible. BIOS features include Wake on LAN, PXE boot, auto power-on and RTC wake for unattended operation, while a Kensington lock slot secures the hardware in shared spaces.

Questions about this item

Does the fanless heatsink stay cool enough during all-day workloads?

The unique heatsink enlarges the dissipation surface so the system runs at 0 dB without a fan, keeping temperatures in check for continuous use.

What is the power draw when the unit runs 24/7?

The included DC adapter is 12 V / 2 A and USB PD charging requires a supply over 24 W with 12–23 V input.

Which display cables and mounts are needed out of the box?

Two HDMI cables for 4K 60 Hz output and the supplied VESA bracket for monitor-back mounting.
