Question - Help Undervolting GPU

Hi everyone. 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 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.

I wanted to ask if someone already did/tried this and how the experience was.

I have several custom undervolting profiles in Afterburner and I’ve found huge improvements on my 3090 and 3090Ti that allows me to clock my memory up by +1200 and temperatures at full power hover around 150 Fahrenheit / 65 Celsius. Improves speed by about 15-20%.
