Update from Sony Customer Support:
The technical team has now reconfirmed that the fan noise issue has been addressed by a firmware update, however this update can only be applied by an authorised service centre. Please kindly contact the nearest service partner in order to arrange for the update to be performed.
Well, good news, of a sort. My nearest Service Centre is over an hour away so more expense to me personally for an error on Sony's behalf.

Peace at last!!
I took the complete unit to a Sony Service Centre (J.F.Associates near to Oxford) for a firmware upgrade. This was done within an hour. I have set the system up and am pleased to report the annoying fan noise has been largely sillenced. The upgrade appears ot have set the fan to run at a fixed speed which is slower than the original so there is no spooling up and down in quiet moments. To be honest the fan noise is now hardly pereceptible. I am now a happy bunny but just wonder why it has taken countless emails to Sony and a wait of 9 months for this to happen when it should have been resolved in the product design/development stage.
Así que ya sabes, llama al SAT. Ellos deberían actualizar el equipo a un firmware que reduce la velocidad del ventilador mitigando así el ruido que hace
Saludos!
