New 2011 15" MBP - running WAYY hot?!

    Just went out and bought the new 15" 2.2 i7 with the Radeon HD6750.

    I was all excited, until I got home and transferred everything over - This thing runs WARM! It's been at idle for the last 30 min (everything moved over already, no disk reading, etc.) and hardware monitor shows between 68 and 72C. According to SMC fan control, the fans kick in at about 60C, and they've been going non-stop at 3000rpm on idle, sometimes kicking up to 4000rpm when temps go beyond 72.

    This seems really warm to me. Main heatsink temperatures look to be around 52 - a difference of near 20 degrees. Does this sound reasonable? It's so warm it's hard to keep on my lap. :confused::eek:

    I've been trying to run L4D2, but it seems to crash as soon as it starts up. When loading, temps get up to 95C

    Got L4D1 to load - played about 5 minutes, and it crashed. Temp at time of crash was 104:mad:

    My 2010 MBP never gets above 100. If this is 'normal' it's going back.

    Never buy first batch of products from anyone. I will let early buyers sort this out. Quad core is new for apple notebooks.

    You have higher 45W TDP and same form factor. It will get warm. It releases more energy.

    How hot was your machine running before you transferred over your files from the older computer. Also how much data did you transfer. I have seen new computers run very hot after a very lengthy transfer of data. If you have a baseline to start at you could compare your temp after you let your new MBP rest for a couple of hours. At least that would be my advice. Take a couple of hours to let the computer cool down and then start using it again as normal.

    If it's still running hot after that cool down period then I would take it back to the store and let them look at it.

    I'd return it. That thing is clearly overheating...

    run in on a clean install with smc and see how it goes, then you will know maybe it was a bad transfer of OS.

    played cs:s for about 30 min. 87 was max. That's more what I was expecting, but cs:s isn't exactly demanding. I'll let it sit for a while and see what it idles at later.

    I never really got a chance to look at what the temps were before I moved everything over because I used a time machine backup when I first turned it on. Regardless, it shouldn't hit anywhere near 105 when trying to load a game, and then crash, requiring a hard power off.

    1. reset SMC

    2. reset PRAM

    if still running hot after that, take him back to the store for another.

    [my Air starts to whir and warm up after big data transfers (like in a rebuild) so the MBPro would for sure]

    The CPU has a max operating temp of 100C -- 104C would be very risky indeed.

    When it hit 100'C+ what was the fans running at?

    This is with the original 5400 drive. I've got an agility 2 that's waiting to go in, but held off because it's still in my 2010 15", and I'm trying to gauge if this is something I should be worried about.

    Please keep us updated. I've got my CTO waiting to be shipped... Heat is a serious concern for me i.e. I don't mind hot but if it causes the machine to crash that's unacceptable and will need to be fixed.

    Edit: I too ordered the top end 15" i7 2.2 but with SSD.

    Yes please do. I also want to know if this is happening to anyone else I just ordered a maxed out 17" today and I don't want any heat problems and I can't have crashes.

    Ah, damn. The OP is using basically the same specs as the one I just ordered. Hopefully this is an isolated problem with just his machine. I haven't heard any other complaints yet, so maybe.

    :eek: Does anyone else have problems like this? 17" owners?

    New 17", and no issue here. Same temps as my old C2D 15"; maybe a bit higher under full load (up to 82 or so). Idling now (with Skype and Coda doing bkg things) at 45.

    I would love it if someone else would post their results.

    I may reinstall a new version of OS X to see if it is still the same. I know this is 45w vs my 2010 i5 520 35w, but I hoped apple wouldn't just shove a higher watt processor in the same cooling design. It looks like I was wrong. I'm used to my 2010 mbp idle at 45 and kicking it up to 90 when playing L4D2.

    This gives me hope!

    Another question: does apple use a thermal grease or a pad of some type? I wonder if the paste is like AS5, and just requires a curing time of some type. I may take a look at it if I put my Agility 2 in tonight.
