Controlling the Secondary Fan on Minisforum AI Pro HX 370

Thermal management is a critical but often overlooked aspect of local LLM deployment, especially on compact hardware like the Minisforum AI Pro HX 370. This investigation details how to control the secondary fan on this popular AI-focused mini-PC, providing practitioners with concrete solutions for maintaining stable performance during extended inference sessions.

Proper cooling directly impacts inference speed and hardware longevity. Uncontrolled thermal throttling can cause significant performance degradation when running large language models, while inadequate cooling risks hardware damage. The Minisforum controller investigation documents the technical details necessary to implement active thermal management on this platform.

For those deploying LLMs on compact edge devices, understanding and optimizing thermal profiles is essential. This work provides a reusable framework for similar devices and demonstrates the importance of hardware-level optimization beyond just model quantization and inference frameworks.
