If you think it's faulty, please don't plug it into your computer
Although computers tend to have short-circuit protection, it's not perfect.
I would really not expect it to get so hot in just 5 minutes in update mode. The controller and screen should not be drawing enough current to do that.
When powering you should leave the tip connected I believe - otherwise if it is trying to heat the tip it's got nowhere but the handle to dissipate it.
Until you get to the bottom of what is going on, it's a smart idea not to leave it alone!
You should take it out of the housing and figure out where the heat is coming from - I would expect to see a chip getting pretty hot under that plastic cover - should be obvious with your thermal camera.

Can someone advise if it's normal for the housing of the unit to reach over 50C when not turned on? I'm hessitant to leave it connected for too long for fear that it will melt or catch fire.
