You might try Sonoma if the activity causing the heat doesn't settle down. I have that running on a 2008 MBP with about half the ram your picture shows your Mac as having. After a period of intense activity it settled down. I'm not using it much as I tend to us my Mac Pro more, but it seems pretty stable now.View attachment 2459932
2009 MacBook Pro.. Installed Ventura today. It is kinda struggling. AirDrop won't work, won't detect iPhone so photo transfer isn't working, fan runs pretty loud and it runs pretty hot.
