When I closed the lid it suspended. Opened the lid and the fan went to maximum. I shut down and booted into Windows 10 (dual boot machine) and the fan was still at maximum. I had to reset BIOS to defaults, so it looks like Ubuntu is still messing up the BIOS settings, at least on the X260. Ubuntu is up to date as of 2018/03/27.
