Fanless Celeron J4125 mini PC

This Defendwe mini PC uses an Intel Celeron J4125 quad-core processor running at 2.0 to 2.7 GHz with integrated UHD Graphics 600. It arrives with Windows 10 Pro 64-bit pre-installed and supports Linux distributions. The fanless chassis measures 131 x 81 x 18.3 mm and weighs 203 g, allowing silent operation in compact spaces.

VESA-mount office and signage system

The unit suits offices, digital-signage installations or home users who need a silent, low-power desktop for web browsing, document work and 4K video playback. It is not designed for buyers who need discrete graphics performance, higher multi-threaded throughput or user-replaceable system memory.

8 GB LPDDR4 soldered memory

The 8 GB of LPDDR4 memory is soldered to the board and cannot be upgraded, so the configured capacity is the final capacity for the life of the device. Storage can be expanded through one M.2 SATA 2280 slot, one M.2 NVMe 2280 slot and a micro card slot.

Questions about this item

Does the 128GB on-board storage need replacement and can it be expanded?

The 128GB on-board storage is fixed but you can add an M.2 SATA 2280 or M.2 NVMe 2280 drive plus a Micro card for extra space.

Which limit appears first when the Celeron J4125 runs at 2.7 GHz continuously?

The fanless chassis relies on passive cooling so sustained 2.7 GHz operation will hit thermal throttling before any power limit.

How much heat and noise does the fanless design produce during all-day use?

Zero fan noise and only warm surface temperatures from the 10 W class processor inside the 131 x 81 x 18.3 mm aluminium case.
