Description
Describe the Ask
Many GPU(s) in the wild getting py-torched with high heat abuse and they die fast. GPU Operator shall offer a power limiting/regulating feature to avoid over-heat & burn.
To Reproduce
Run your 600Watts Air/Poorly-Cooled GPUs next to each other for model train/fine-tune and observe accumulated temps surpassing >100C Temps.
Requested feature
GPU Operator could able to monitor operating temperature of each GPU and keep it in allowed Temp Range, by using "nvidia-smi -pl" power limiting ability with autonomously if this feature is enabled.
Environment (please provide the following information):
- GPU Operator Version: 25.3.2
- Container Runtime Version: Driver Version: 570.148.08 CUDA Version: 12.8
- Kubernetes Distro and Version: RH OCP 4.19
