This looks like a good fan setup with the U9S: [MEDIA=reddit]sffpc/comments/den5hr[/MEDIA]Or https://imgur.com/r/sffpc/OVagCd5As for bottom fans, I've read that no fans works well, drawing air in from the bottom using only the GPU fans; the setup above would work to exhaust the heat it's dumping into the case. I've been satisfied using 2 fans as intakes on the bottom & on the side (Bionix P12s) and a 92mm Noctua on the back as exhaust, though I haven't tried other configurations.
