A developer has found a workaround for overheating issues with the DGX Spark GPU when running large language models like Ollama and Qwen2.5. The GPU, specifically the GB10, lacks user-accessible power and fan controls, leading to temperatures around 83°C under sustained load. By using the `nvidia-smi --lock-gpu-clocks` command, the developer created a daemon that dynamically adjusts the GPU clock speed to keep temperatures below 78°C, reducing them to a sustained 72°C. While this method slightly impacts inference speed, it ensures 24/7 uptime and thermal headroom. AI
