    you could try to disconnect blu ray drive and fan. Only motherboard, on off board and power supply and then try to turn on.

    If you do keep a finger touching CELL surface, and be ready to disconnect the power cable with the other hand inmediatly when feeling some heat in CELL

    Otherway, if you turn ON a PS3 without fan and keep it working for... not much... 5 minutes... is going to die by overheating
    Is awesome how fast the temperatures increases when there is no fan/heatsink... up to a point that the test i mentioned (by having a finger touching CELL surface) is going to burn your finger

    What he should do is to take a multimeter and check the lines i mentioned, ground is not needed, but is needed to check that there is voltage in one of the wires. That voltage probably comes from his own voltage regulator (not directly from PSU)

    And the other wire with the PWM signal from syscon... well, to check the signal is needed an osciloscope (expensive equipment), but you can use a multimeter to verify if there is a connection in between syscon and the PWM pin of the fan connector (in other words... the line is not "broken")
