    Hi,

    I have a 2006 White Intel Imac and I recently replaced the Superdrive with a non apple Panasonic Superdrive Model: UJ-85J-B from a used Acer Laptop.

    The replacement drive has no sensor circuit board.

    After putting it back together there was a loud humming noise and I assumed it was the new drive but when I took it out and started the Imac without it the noise remained?

    Now I am thinking it is the fan just below where the Superdrive sits?

    I blew out as much dust as I could from this fan and around the bottom of the case and that made the noise just a little less annoying.

    It sounds like it is about to take off like an jet airplane?

    Any suggestions?

    Thanks.

    Monkey-Bill :)

    Solution Found:

    Hi All,

    I found the solution to that loud humming noise, it is the cooling fan.

    The new replacement superdrive has no temp censor so it is causing the Imac to think that it is overheating there by making the fan speed up to compensate.

    I need to pry off the temperature censor off of the defective superdrive and glue it onto the replacement drive.

    I hope this info helps other members out there with similar issues.
