    I'll keep it extremely short.

    Windows 7. Bootcamp. BFBC2. Settings on low. GPU at 90 degrees C. Stock clocks.

    Is this normal? I've seen posts of people posting OC'd GPU's running in the 70's...

    Temps depends on a lot of things. Ambient temperature is one. Ventilation is another.
    The MBP doesn't have a very good cooling system and that can be compounded by poor TIM application at the factory (happens to every manufacturer), a fan that doesn't work efficiently/effectively because it's clogged, and a whole host of other things.
    When was the last time you cleaned up the inside of your computer?

    It's two weeks old. Vent isn't blocked. Ambient temps 70 F.

    SOmetimes laptops just run hot. The game may have nothing to do with it. On OSX I can play 'And Yet It Moves....' Steam game; sometimes runs hot other times doesn't, same settings all times. Games have different requirements most of the time depending on what you're doing on it. Also, if its new, it'll be fine and you should conduct more tests first, such as turning the settings up and see if the temps rise more and how hot they level off at to determine whether its normal.

    Never go by touching the case of the laptop and even though the temp reported by istat, etc, can be reliable, you can prob take 5oC or so off of that due to their placement.

    Hope that helps a little.

    Hi, my MBP is running extremly hot too, so hot that i can't even touch the area of the left speaker.

    How can i measure the temp with some accuracy?.
    Which is the highest temp to start worrying?

    Sorry, maybe i'm a bit out of touch, but I've had the mbp for a couple of year or so, and i've never heard we must clean up the inside:eek, but If it is easy, i'm willing to. some advice?

    In Windows use HWMonitor, in OS X use iStat Pro.

    When gaming, my left speaker area gets very hot, but as long as the internal components aren't frying, you're fine. Under 100C is fine. Mine hits a max of 99C.

    intel themselves say that a processor should not exceed 80% of maxtemp for any extended periods of time, there fore threshold is 80C, CRITICAL is 100C and shutdown is 105C

    http://ark.intel.com/Product.aspx?id=42599&processor=P9700&spec-codes=SLGQS
    spec sheet shows the tJunction temp at 105C ( shutdown due to heat )

    Thanks a lot. I've already install iStat Pro and works fine. The CPU temp is now 71º (with parallels running).

    wow, good for cooking.

    Pretty much anything that sucks in air will have accumulation of crud on the inside. As far as cleaning it, if you want, just get some compressed air and blow around the keyboard and in the vent in the back of the Macbook. Taking it apart should be fairly simple. There's a few videos about it on YouTube if you want a guide. Only take it apart if you think it's really nasty though.

    105 is where it actually will shut itself off, 100 is where underclocking starts ( critical threshhold )

    Thanks, really helpful. I'll try.

    Hope so. Yesterday i was checking the temp several times, and my MBP is running in the range 70-75º C. Really unconfortable for working with it on laps...

    OP, whats the specs on your laptop? If you're running the i5/i7, they're known to run much hotter than the previous gen C2D MBP's.

    Where did you hear this? The i5/i7 and C2D are the same TDP(35 watt). The i5/i7 also have more power saving features.

    Report: Core i7 MacBook Pros running hot
    At idle, it's probably the same if not cooler than the C2D. But when tasked, it's been known to run much hotter.

    The P8600 in the MBP 13" 2010 has a TPD of 25 watt. in mine the CPU runs iddle at 42c-43c. Running video conversions I've seen it reach 70c.

    What exactly is 80% of a temperature? I would assume you must use absolute zero. In that case 80% of 105C is ~29C, so the whole 80% thing sounds like BS.

    Those temps are a bit unusual, but then again, it's a Macbook Pro. Are you running an i7? That might explain it a bit more. BFBC2 is somewhat CPU intensive.

    80% of 105 is 84. However WE'RE TALKING ABOUT TEMPERATURES, so you must normalize for absolute zero. So I converted to Kelvin like a pro first. ;)

    Take a look at your flawed logic:
    100C = 212F (proper conversion)
    80% of 100C is 80C (by your math)
    80% of 212F is 170F (by your math)

    But 80C doesn't equal 170F. So it's your turn to learn math. :)

    If you're still stuck I can help you out.

    actually they go by 80% of crit temp and not shutdown temp so 80% of 100 is 80

    ahh yes I remember the days of having to figure absolutes and conversions

    I've heard of grammar Nazis, but math Nazis as well?

    If you really want to get down to it. In this case there wasn't a need to normalize for absolute zero, because well, we are not in a freaking science lab where measuring against absolute zero matters. It is obvious that percentages of temperatures do not scale normally between temperature units and it is quite apparent Intel did not want you to do any conversions when talking about their safety thresholds.

    If you really still want to have it your way, you can just use your laptop in a refrigerator to stay within the 'threshold'. Trying to be 'smart' or a "pro" doesn't get you very far here.

    Anyways....I hope the OP gets his heat problems sorted out or maybe is up for a replacement. I just want to know if he's running an i7 proc.

    It's not obvious; this is more than science lab, it's freakin' microprocessors, some of the most advanced technology on the planet.

    I can't believe Intel would use such wrong terminology.. where again to they talk about 80% of a temperature? I didn't see it in the link.

    The combination of apple drivers and fans react late when the temps go high..your mac must have reached 90c for only 2-3 minutes before the fans kicked in and bought the temps to upper 60's.

    Thats exactly what I found out. In WEI the CPU hit 97C for about 20 seconds, then, the spun up to 5000rpm and the CPU dropped to 70C.

    The fact that the uMBP can play games does not mean that it plays games very well. The solution is simply to avoid playing games on what is obviously not a very robust cooling system.

    That can be said of just about every (gaming or not) notebook out there minus a few exception... May as well not use it for other cpu/gpu intensive tasks while at it...

    My 2 year old XPS 1530 never went lower than 65c while idle and would reach and maintain 95c under load. You could cook an egg on it.

    I played Crysis on my Macbook, and after 3 minutes or so, the fan hit 5300rpm, and the CPU and GPU never got over 90C.

    After reading the whole thread the causes of the heat seem more or less clear, but what about the solutions, if there is any...

    Here are your options:

    Mod it: http://forum.notebookreview.com/app...tle-underside-case-mod-big-temp-decrease.html

    Under volt it.

    Get a coolering pad.

    Don't play games in bootcamp(I think games run a little bit cooler in OS X)

    Use SMC fan control to set your fans to 6000rpm(in OS X), then reboot into Windows and game.

    Use lower setting in games(e.g medium istead of ultra & 1024x768 instead of 1440x900).

    Hold up, I don't think you're getting my point. Never have I said that a Mac would be the best option for gaming, but this is my only option for the foreseeable future. Secondly, I already know that the MBP's do not have a robust cooling system, but I've compared to other MBP's (sorry, I failed to mention that it was the 13" before, but now you guys know), and my MBP just doesn't measure up in terms of cooling.

    Also, to the person who mentioned the delay in fans kicking up. My computer boots at 6200 rpm when I intend to game.

    Can't give exact temps, but my CPU is ~88 degrees C throughout two hour hours of game play, while my GPU is in the low 90's. I've had many people report degrees in the 70's for both playing the same game (without any significant differences in our systems).

    PeakingDown, keep in mind your 13" MBP only has one exhaust fan compared to the dual-fan design of the 15-17". Even at idle I find the 13" MBP to be anywhere between 5-10C in difference compared to the other models. If you're comfortable working with computers, you can easily open up your MBP (screws in bottom casing, you can find a guide at iFixit) and check/replace the thermal paste with something like Arctic Silver 5 or equivalent. I find that it does help in lowering your temp by a slight bit.

    I only game in OSX right now on my 2010 13", so I don't know about Windows... but when I'm pushing it maxed out the fans stay anywhere from 5000 - 6000 and the temps never really get over 80 - 85 if I spin the fans up manually. if I let it go on its own, it gets up to about 90, then spins the fans up and keeps it down around the same 80 to 85.... but thats only when I'm pushing it maxed out. I don't run the highest or best graphics settings, cuz i don't really care about graphics, but very often playing my fans are only around 5000 and its around 75º.

    What I'm posting is a 15-23 degrees Celsius difference.

    And I'll look into applying better thermal paste.

    Ok, here's what I did while playing Crysis. I went under the power settings and set my CPU to go to 70% max. Now, playing Crysis @ 1600x1050 and medium on everything else(no Anti-Aliasing). Max CPU temps: 83C, Max GPU 88C. Also, the fans are at 4500rpm, normally they're at 5500rpm.
