Rumours of a problem with the PS3’s cooling system has been taken so seriously that it has caused Sony’s shares to fall.

At the Tokyo Game Show, the PlayStation 3 consoles on display apparently experienced technical difficulties, which Sony attributed to overheating, not because of a flaw with the cooling system, but because over 200 PS3s were clustered together in poorly-ventilated kiosks.

Trade shows are always hot and stuffy affairs and the concentrated heat around some devices can cause them to fail.

However, Macquarie Equities analyst David Gibson’s report has already done the damage on the stock market, as Sony has been downgraded from “buy” to “hold”.

The consoles are due to start selling in Japan and the US in November, although Europe has to wait until March to get its share.
