Hey! So I finally got around to get batteries for my UPS unit and I've noticed that the unit's fan is always on. Not going full blast but noticeably on. Is this normal? There's not a lot of load and it's not warm at all. Is there a way to lower the fan's rpm? I've checked online but I can't seem to find any firmware updates for it.
