[Elecraft] [K2] K2/100 - where does all the hot air go?

[Stephen Prior]

I have the 100W amp mounted in an EC2 enclosure, all working great now, no
small thanks to Don!

I have a question.  The little fan on the back seems to push air into the
unit, yet there is no obvious exit for it.  Or am I missing something?
Almost seems like I need an automatic vent popping up at the front (that
little panel could lift) like the vent on the back of a Porsche!  Perhaps
replacing that little panel with a perforated one would help?

I'm a little surprised at how quickly the fan comes on (on cw, I haven't
used ssb yet), and also quite taken aback by its noise!
