[Bug 464593] Re: Sony Vaio Shuts Down "Critical Temperature"

[Stefano Travelli]

To be honest and compensate my rant against Sony, it must be said that
the poor design is not in the cooling system itself, but in how hard is
to disassemble the laptop in order to remove the dust obstructing the
fan.

When cleaned properly it usually stays cool and quiet.
