This is very well possible. When i got my net5501 i found out that
the case has no thermal design whatsoever and is prone to overheating
even in unloaded conditions (measured 70°C cpu temp when _idle_).
This is no suprise considering that only the few holes on the side
contribute to cooling, which is definitly not enough if you want to
disipate more than 2-3W (the board alone uses something in the 5-7W range).
The holes on the bottom do not contribute in the least as they are covered
by the board and hence their air flow is blocked.
A few people have reported that putting the case on its side to
get a chimney effect has helped a bit. I installed a small fan
to be on the safe side.
Over all, i do not recommend getting the standard net5501 case as
it is a clear misdesign. If you already have it, consider putting
a small fan in.
