IMO, if you aren’t using at least a 360mm radiator there’s not a lot of point water cooling.
The point of water cooling is that you can transfer the heat from the heat producing component out to a large surface area by physically moving the hot liquid. 2x 360mm radiators give you a ton of cooling capacity. 1x 240mm? You can do almost as well for much less money with a really nice air cooler.
Gnome requiring extensions for some basic functionality and happily breaking them are deliberate design decisions from the Gnome devs. Compare that to the kernel’s long standing “we don’t break userspace” policy. I don’t use Gnome.
Wayland has taken a long time to get where it is now, but on my laptop which only needs to deal with one 60 Hz normal DPI screen running a web browser it was ready years ago. There have been a lot of edge cases that needed to be chased down - I needed VRR in XWayland apps and the ability to turn off DPI scaling for XWayland before I could switch my desktop over.
Well, feeding voltage in that range to 24V fans would be fine, but “19 to 24V” makes it sound like a USB type-C charger or something which communicates with the device to set its output voltage. A power supply should have a single voltage.
Unless it’s one of those generic power supplies with a switch to set the voltage?
