Personally I had zero issues with upgrading my server to Debian 13; it’s an installation dating back to Debian 9 or 10 with a lot of services installed.
The only inconvenience I had was that somehow Transmission 4.1.0 beta made it into debian stable, and beta clients are usually not allowed by private trackers. I switched to deluge and called it a day.


If I had to guess, the second curve allows the GPU to boost higher than the first one, so it generates more heat.
