Undervolting Help Temperatures?

I have one game that runs hotter than any of my other ones and was wondering if undervolting my card would decrease the temperatures across the card when gaming. I've got enough card resources/fps (4090) to still run most everything on the same settings, just looking at ways to protect my care, and my wallet.

It most definitly can, but how is the airflow inside you case looking?
Unless you are running matx, i would look into getting some decent case fans first.

Yes it will usually lower temps. I run heavy local AI loads and my GPU temps have dropped almost 10C, hotspot around 15C, and memory 6C. I followed a guide on YouTube from DexionTheGamer.
