My setup: dual screen, on one of them there's YouTube always on with some booktuber or d&d campaign, private and work chats, on the other screen browser and terminals. The fan that's sucking my vape fumes next to my desk has been running non stop for a couple of years. I sometimes turn it down to one, but it's always on. Sometimes the browser/terminal combo gets replaced by Project Zomboid. I'm in this chair 10-18h per day, almost every day. I'm okay. Everything's okay.
