– Upgraded to Intel Core Ultra X7 358H with integrated Arc B390 iGPU for significantly better CPU and gaming performance while remaining fanless.
– Aluminum cube chassis with circumferential cooling fins doubles as a heat sink for silent operation; dimensions: 12 cm edge length.
– Dual M.2 slots and versatile I/O: 2 USB-A, 2 Ethernet, 2 HDMI 2.1 on rear; front USB-A and 2 USB-C (one with Thunderbolt 4) for expandability.
– Target price €1,850 (config: 16 GB RAM, 1 TB SSD), positioning as a premium fanless mini PC with strong gaming potential at 1080p.
Kubb updates its popular mini PC by moving to Intel Panther Lake, promising beefier core performance and stronger graphics thanks to the integrated Arc iGPU.
New processor and graphics boost
The Kubb Fanless replaces the Intel Core Ultra 5 225H with the Intel Core Ultra X7 358H, aiming for notably higher CPU power. The built-in Intel Arc B390 iGPU is also said to enhance gaming performance, allowing smoother experiences in lightweight titles at 1080p with mid settings.
Gaming and pricing
Intel’s top integrated graphics in this setup are advertised to handle games like Anno 117: Pax Romana, Forza Horizon 6, and The Outer Worlds 2 at 1080p on medium details. The price is listed at €1,850, placing it above several laptops with comparable CPUs, yet the vendor emphasizes silent operation as a key selling point by cooling the chip passively.
To achieve silent cooling, the case is built from aluminum to act as a large heat sink, with circumferential cooling fins increasing surface area for more efficient thermal management. The compact square form keeps the dimensions small, while still housing two M.2 SSD slots. Back I/O includes two USB-A ports, two Ethernet connectors, and two HDMI 2.1 outputs; the front adds another USB-A and two USB-C ports, one of which supports Thunderbolt 4.
Availability and configuration
The Kubb Fanless with Intel Panther Lake is now on sale through Kubb’s online store. A configuration featuring the Intel Core Ultra X7 358H, 16 GB RAM, and 1 TB SSD is priced at €1,850 (about $2,150) not including shipping, continuing the brand’s emphasis on noiseless operation.
- Two M.2 SSD slots for drives
- Thunderbolt 4-capable USB-C on the front
- Passive cooling via a large aluminum chassis
The compact cube measures roughly 12 cm per side, balancing performance, cooling, and space efficiency in a fanless design.
Overall, Kubb retains its focus on silent operation and compact size while upgrading to Panther Lake, appealing to buyers seeking a quiet, space-saving mini PC with reasonable gaming capability at 1080p. The €1,850 price tag reflects the premium for passive cooling and improved CPU/GPU performance in a small form factor.
