Writing this from a X1 Gen9, I wouldn't call the following "very good". Not sure if it's already fixed in new firmware (and couldn't google the support forum right away), but I had to
* switch sleep mode to stop it from getting hot while asleep;
* disable touchpad in BIOS to stop it from spinning fans while awake — great for me because I don't like it anyway and vastly prefer the trackpoint, but people not used to this consistently go wtf while trying to show something on my laptop.
I had some of these issues with the 5.17.x kernels but once I switched to Fedora 36 and 5.18.x, and updated the BIOS, the situation improved dramatically and sleep was fixed.
