A thought, you need a lap cooler that plugs into the usb to keep the battery cooler. I would assume that if you are doing 24/7 you are connected to power , definitely you want to keep your unit cool. A desktop is better as it has at least 2 cooling fans and is intended on being on 24/7.
If it were me in the same situation as you are, I would go with a laptop lap cooler to help the fans keep it going. Then with the display, tune the brightness down if not off to help with the cooling.
