One reversed fan dropped dual-GPU temps from 85°C to 78°C even at 325W

Under gpuburn, the author's two GPUs ran at 85°C — stable but toasty. After spotting one fan mounted backwards and flipping it, temps fell to 78°C even with the power limit raised from 300W to 325W. Takeaway: airflow direction matters enormously in multi-GPU local setups; verify fan orientation when thermal testing.
