i have tried on my 60gb aswell but not happening unless there is another button sequence
Nope, the fan test doesnt exist on the old hardware. It was brought in much later. This makes the 60GB a pain if it YLODs, since there is no way to test if its the powersupply, or eject the disc without opening it. The fan test work even if its YLODd - which is a good test to see before you open it if its not the powersupply which crapped out (Which is also a cause for YLOD).
