LRP Power Supply Competition 13.8V/20A question

[AceofAxe]

Just got this the other day. Used for the first time at the track and noticed a faint burning smell. It never got hot, it did get warm though. Also the fan didn't seem to kick on at all. I believe the smell could of been just dust or "newness" burning off. I used it for the whole night and never had any issues. Anyone else have any of these issues with it?
