RTX 6000 Thermal Hack: MI50 GPU Mounts Fit with Modifications, Cut Temps in Half Under Load

r/LocalLLaMA·low signal

A r/LocalLLaMA user discovered that old AMD MI50 GPU cooling mounts semi-fit on the RTX 6000 with minor modifications, cutting temperatures in half under sustained inference load. The card still throttles after 30 minutes of stress testing, but the hack demonstrates the creative lengths local inference builders go to for thermal management on workstation GPUs not designed for 24/7 inference workloads. With 75 upvotes and 28 comments, the post exemplifies the 'if it works, it ain't stupid' hardware hacking culture of the local LLM community.
