Something interesting with unique(?) board, cooling, 2x10G ethernet and integrated PSU.
User Manual
Availability: September 2025.
Note
The included 10G NICs are unstable on Linux with older kernels. More info:

Make sure that you're running kernel 6.17.11 or 6.18+ to avoid problems.
Fan control (Linux)
The stock fan curve is conservative (~40% duty only at 93 °C), so under sustained CPU/GPU load (e.g. local LLM inference) the
APU reaches Tjmax and throttles. The MS-S1 MAX exposes no standard Linux fan control (no hwmon PWM, no tachometer, no ACPI fan
object), and on Fedora ec_sys is unavailable while Secure Boot lockdown blocks debugfs.
Open-source tool for this board:
ms-s1-max-fans-control
— a small signed kernel module exposes the EC as /dev/strixec (works under Secure Boot + SELinux), with CLI/GUI
fan-curve profiles and systemd persistence.
Reverse-engineered EC map: CPU temperature at 0x09; fan-curve tables at 0x11 (fan 1) and
0x31 (fan 2), 7 × 3-byte records [temp, hysteresis, duty%] read live by the firmware. Note: this
board is not a Sixunited AXB35-02 (different EC layout). Full details in the repo's
docs/EC-MAP.md.
