PS3 40GB Hidden Fan Function

The PS3 has an inbuilt fan which seems to wok better than the Xbox's for obvious reasons, such as the 3 red light which has plagued many people due to the rush that Microsoft wen through trying to beat the PlayStation's release date which they did not have to worry about since it was delayed for quite a while.

This function only works for the 40GB model for some reason, what you have to do start this up is eject he disk to make sure it doesn't get damaged. Then turn the power off at the back of the PS3, then hold down the eject button as you turn it back on from the back. It will then turn on with the fan running at it's top speed, it will go for about 2 minutes pushing all the dust out (best done when laid down on it's side). Once stopped the red light on the front will flash, then turn it off and back on again with the switch off the back.
This is only really helpful if it's in a shadowed corner where dust may collect.
