Undervolting GPU

I thought about undervolting my GPU with the MSI Afterburner but since it is not for gaming but for AI generation, i am not sure how this would impact the speed/performance/stability and the generation time.

Key points

  • I am currently using local Image/Video Creation a lot but especially for models like MiniMax H3 my GPU fans are going a bit crazy.
  • Everything is working fine, but i do not want to break my hardware in the long run.
  • I wanted to ask if someone already did/tried this and how the experience was.
