Introduction

Internal Prerequisite.

  1. W2HnnXkZIR6pR4XO

    • Remove the following four screws:

    • One 9.3 mm T10 Torx screw with a large head

    • Three 9.3 mm T10 Torx screws with a normal sized head

    The 4 srews are equal

    • Pull the optical drive thermal sensor connector toward the top edge of the iMac to disconnect it from its socket on the logic board.

    No need to do this! Just gently pull up the felt-pad sticky on top of the thermal sensor (looks like a tiny circuit board), then (again gently) peel the thermal sensor off the ODD. Leave it hanging while you remove the ODD and replace it with the SSD, then just put the thermal sensor covered by the protective felt-pad back onto the SSD enclosure.

    I agree with cdansmith1, above.

    I had removed the sensor completely. Booted up and the fan was like a jet engine - 4200rpm! I opened up the mac again to check the LCD thermal sensor cable was connected properly (as warned in Step 8). It was.

    So, I simply used the spudger to peel off the felt sticky pad from and then the optical drive sensor too from the drive I'd taken out. Stuck the sensor onto the SSD using the same sticky pad, plugged it back into the original socket. Bingo. Booted up and everything was back to normal.

    • Lift the inner edge of the optical drive and maneuver its connector past the GPU frame attached to the logic board.

    • Carefully pull the optical drive off its mounting pins on the right side of the outer case to gain clearance for disconnecting the optical drive cable.

    • Allow the optical drive to hang down as you de-route the optical drive thermal sensor connector from behind the GPU heat sink.

    this part is complicated because the wire is very delicate. when you try to extract it passing through the others elements this wire trap it very easily on the other elements of the logic board

    • Disconnect the optical drive cable by pulling its connector away from the optical drive.

    • Remove the optical drive from the iMac.

    • Do not forget to also move the thermal sensor from the optical drive to the enclosure when you install the second hard drive.

Conclusion

To reassemble your device, follow these instructions in reverse order.
