    OK...I Bought a used 2010 i5 2.53 ghz 15" Macbook Pro with a bad logic board and no hard drive. I bought a 2010 i7 2.66 logic board and installed the heat sinks from the old logic board to the new one with Arctic silver 5. I used CCC to clone a SSD hard drive off a 2010 i5 2.53 ghz 15" and installed the hard drive.
    The Macbook pro takes about 2 and a half minutes to boot up and the fans are running at 6000rpm other than that everything is perfect. I'm using Istat Pro and it isn't show any GPU or CPU temps and in activity monitor it is showing kernel task @ 167% of CPU. Please HELP!!!

    Using Mac OS X Lion Version 10.7 (Build 11A459e)
    I repaired disk permissions already and Verified disk

    That's an early prerelease build of 10.7, so get a proper, released version of the operating system on there before you waste time troubleshooting.

    I think your keyboard is defective. :rolleyes:

    Seriously though, wipe the hard drive and install OS X from scratch.

    Are you certain you reconnected and properly installed all the thermal sensors on the board?
    If you haven't run a hardware or service diagnostic after doing the board swap, it's probably worthwhile to do that; it may narrow down the trouble.

    OK...I will look into the thermal sensors.
    In addition, I will wipe the hard drive and start from scratch. I have another Macbook pro 2010 15" 2.53 I5 that I can check the hard drive with or swap hard drives. It works perfect and this is where I cloned the hard drive from.

    Be careful with using an OS from a different machine, even a different Logic board, OS X used to be Universal if you got the Retail OS X disks, not anymore.
    Also, run AHT before doing anything else, you might have missed connectors or they are not properly fitted.
