One unconventional way to test for overheating would be to open the
box up and get a desk fan and aim it into the box medium to high
speed.  I've been able to keep servers with no fans at all going while
I went to buy parts.   Clean out the dust though before you do that
and while you're at it make sure the fans aren't clogged with dust
bunnies.  That could slow them down enough to cause problems.

It would be a bit odd to have overheating with 3 fans in the box, so I
would be tempted to change the battery too.
