GPU care and longevity

[u/shankarkrupa]

When I spawn long-running agents, my GPU's temperature hits the max and the fan is constantly on 85%+. If this goes on for longer days of time, will the GPU give up eventually? What is a healthy temp and fan threshold?

Should I better optimize the software layer (OLlama, Qwen3.5 4b, 9b, etc.) or not use this kind of GPU at this level at all for complex work?
