The go-to is the noctua nh-l12s but it’s not compatible with the gigabyte board I have so I’m using an nh-l9. Don’t remember if it’s a or I. It works adequately but if I were to do it over I’d get a motherboard that were compatible with the bigger cooler.

I crammed a mini itx x570 motherboard, 5800x3d and 6900xt into a fractal ridge case that sits under my tv and looks like a console. if you’re going to run steam on linux stick it’s easier to stick with AMD GPU.
