Shall we thus forget the whole thing as the book states there is some warmth caused by the built-in power source but nothing to worry about???
Nevertheless, it would have been interesting to know if yes or no there is a fan in the KN7000.
Anyhow, the origin of this thread was the question "is prolongued blockchord playing harmful to the board" and the answer seems to be clearly NO.

Hi Freddy,
I can see no reason why adding any of the Technichord options, will make the KN7000 generate significantly more heat.

However, playing the keyboard continuously at maximum volume, could contribute to greater heat output from the power supply components and the power amplifier modules, which drive the internal speakers. The extra power required to produce the increased current drive to the speakers, has got to come from somewhere. That 'somewhere' is the power supply and increased current demand on any power supply, normally generates more heat........

Hi Folks, having checked my service manual there is no reference to a cooling fan, the Fan Bags listed appear to be the owners pack bags,why Panasonic call them this is best known to them.
Regards John.

I couldn't give a monkeys whether there's a fan or not so long as my KN7k keeps nice and real cool!! Which so far it has. Derek

Hello Derek,
Just to say that I love your expression "give a monkeys'". I hadn't heared that for ages.
As to the warmth or even heath I still get it and sometimes plenty. Let's just hope it
will do that for a very long time still to
come and if possible, without any harm to
the board.
