    Nothing is wrong with it, the power supply itself. But the Power Supply fan makes an irritating noise around 700-750rpms, and for some reason when im editing etc, it loves to float around there...

    The noise, its like a tapping/clicking... like if its hitting a wire, but there is no wire there (i checked). Someone told me it maybe the ball bearings of the fan. So what I was going to do was go in there and reseat it, or just check it out.

    Hit it with the torx screw, and dang it, stripped it....so ya know. that sucks. Ideas?

    Dremel, cut a slot, use a flat blade screwdriver

    depending on how bad you stripped it, try a pozidrive bit.

    I stripped a tiny screw on a MacBook Air disassembly a couple months ago and found these bits did the trick:

    New screws

    I hate Torx screws, but haven't found a good alternative till now. Check out Outlaw Fasteners. They claim to not strip, slip or wobble off the bit. Looks like it would really work. Here's the link: http://bit.ly/outlawscrews

    Slightly larger plastic screw might take hold with some muscle.

    They make bits for drills that grab the screw and twist instead of drilling down.

    I would try that first. If that doesnt work, you can always drill out the screw. Place a magnet underneath the screw while drilling to catch any shaving that could touch the PCB and short something.

    Obviously, DO NOT drill into the PSU with the machine running and plugged in!!

    If the supply is still in your Mac, why not use some fan control software to set min fan speed above the bothersome point and move on...

    Sparks aren't the problem the metal filings are. Mask everything up with tape and polythene. Leave the psu plugged in to earth it as a spinning dremel generates static!

    Other option is more brute force - bang a slightly bigger torx bit in to fit.
