Compact fanless mini PC

The KUBB KM-300-16256P-RP is a 3.15-inch aluminium barebone that ships with an Intel Core i3-N300 processor, 16 GB of LPDDR5 memory and a 256 GB M.2 SSD. It runs Windows 11 Pro and targets office, kiosk or digital-signage deployments where silent operation and a tiny footprint matter.

Pre-installed OS and fixed memory

Windows 11 Pro is already licensed and installed, so the unit boots to a ready desktop without extra media. The 16 GB LPDDR5 is soldered and cannot be upgraded, while the single M.2 slot holds the included 256 GB drive and accepts one replacement module.

Gigabit Ethernet and Wi-Fi 6 limits

The Realtek RTL8111H controller caps wired throughput at 1 Gbit/s, and the Intel Wi-Fi 6 AX201 radio tops out at the 802.11ax standard. Bluetooth 5.2 handles peripherals, but the 30 W AC-DC adapter and single HDMI output restrict high-power peripherals or multi-monitor setups.

Questions about this item

Will the soldered 16 GB LPDDR5 memory need replacing later?

The 16 GB LPDDR5 is soldered and cannot be upgraded; no memory replacement is possible.

What limits performance first during sustained loads on the i3-N300?

The 6 W TDP and fanless aluminium chassis throttle the 8 cores before thermals become critical.

How much heat and noise does the fanless 30 W unit produce running all day?

Silent operation with surface temperatures staying warm but safe thanks to the aluminium shell.
