So the A4 definitely has a new chip design?  And not a whole bunch of A2 chips combined together with a really powerful fan?

If the pricing would drop on this by 50% - I would certainly be interested in some units.  But the noise and temperature are concerning.

Did anyone get to measure the actually noise created by the machine?

And did I read somewhere that after 4 hours the unit got up to 60 degrees C?  Is that right?  Was that temperature based on the air coming out of the machine?  Or the actual temperature on the chip?

If it is air coming out of the machine -- how in the world would one keep your room cool?  If memory serves -- I believe my A2 units would average 33 to 38 degrees C -- depending how many units I had in the room and if I had some AC going.


EDIT:  I believe someone mentioned noise at 88db or so?  That is loud!
