    Just got my MBP 17" last week. Over all - sweet. No known problems, however found out about heat and whine. High pitched whine, working on getting rid of it. Interesting to say the least.

    Heat - CoreDuoTemp reports 63C at 10% usage, will see about ramping that up to more usage (specInt tests or something)

    Boot Rom Version MBP12.0061.B00
    Serial Number: W8622xxxxxxx
    SMC Version 1.5f8

    No updates applied (unless unbeknowest to me) since purchase.

    Hi all,

    I have had the heat issue as well, even though I have had my MacBook Pro sitting on one of those things that elevate the back so there is air flow underneath it.

    I called Apple Care and they were really nice, walked me through a number of tests and told me the computer was fine. Like I have seen on a few other posts, they told me that it was never meant to sit on your lap (I have never used it on my lap, my concern about the heat was/is that there will be damage to the computer). Anyway, at least it is on the record that I called in about the heat.

    All that being said, I want to update the firmware like I see some of you did but when I try it tells me that it is not for my computer.... I don't remember the exact message but it wasn't "your computer is already up to date". Maybe I was not using the correct URL.

    Anyone else have this problem?
