    Hi, I'm a recent switch from Windows Computers.

    Love my new cMBP 2012 15". OS X is such a breeze to use and I am happy I finally made the switch.

    My only complaint is the heat. Now, I know there are lots of threads on the MBP's heat, and searched through and it seems 80-85 C is normal for the GPU under load.(I'm using a widget called istat pro I found in one of those threads) I don't know.

    With that said, is there anyway of reducing the heat under the keys on the left side? Under load top left gets absolutely burning, and it can be painful after awhile because the space in between the keys are so hot. Is there anyway to reduce heat to the keyboard? Will a keyboard cover help?

    Well its aluminum.
    Thats what its suppose to be doing, releasing heat from the inside.

    If you are really concerned, use a external keyboard or buy one of those cooler fans under your Mac.
    Im pretty sure those dont work that great but better than nothing.

    Yeah um, so if you actually plan on using your computer, the macbook pro isn't for you. Get a mac pro instead, or switch back to Windows.

    And while I realize I come off as a jerk, I'm 100% serious. I purchased a fully maxed out Macbook Pro a few months ago, and returned it after it became burning hot just transferring my files onto it, I wasn't even using the CPU all that much. Apple laptops just get warm, and this current generation get especially hot.

    One big problem for MBP since day 1 is heat.

    The only way around it is to use keyboard cover, and it actually helps a lot for your fingers.

    I see, but really it's only my GPU that gets really hot. According to my observations of using istat pro, my CPU has never exceeded 70 C.

    Well, my old windows laptop was worse. It would get super hot to the point that the GPU and CPU would down-clock to stay cool. In an intensive game, the framerate would drop every 10 seconds because of the components would downclock. The difference was that all the heat wasn't coming up the Keyboard and raping my fingers. I guess I will just get used to it, though I'm going to college in a week so I won't be gaming much anyway.

    Heat can be an issue with laptops in general. I've also used some very hot Windows laptops too so this problem is not solely an Apple problem. I do agree that Apple should be more helpful in solving this problem.

    Apple's desire for thinness and quietness helps to create this heat problem you have noticed. Being made out of aluminium doesn't help either. If fan noise doesn't bother you then you can try one of those apps that let your control your fans. I've noticed on my MBP the fans turn off or slow down sooner than they should for a comfortable temperature when typing. Fan controlling apps will let you keep the fans running at faster speeds than usual.

    The suggestion of using a cooling pad or using an external keyboard are also other options you can use. Although those solutions are better for desktop usage since always carrying a cooling pad or external keyboard when you need to be mobile can be a little annoying.

    Just as reassurance, the heat and temperatures are normal - but I realize your concern is reducing it.

    As others have suggested, laptop coolers and you could possibly go as far as a USB keyboard if you are stationed at a desk or table. You can also use fan control applications to maximize the rate at which your fans will spin, thus cooling off the laptop of course - however if you are performing GPU intensive tasks they are most likely ramped up anyway.

    It's just going to be something that you have to deal with. A cover could in fact help if it covers the areas that you are concerned with, just make sure that you don't block any vents or anything.

    If you are concerned about temperature and want to reduce it elevation of the rear of the machine helps, as sitting flat on the desk only reflects the heat back to the base of the Mac. You can buy passive aluminium coolers like Rain Designs Mstand or iLap. Most powered coolers are designed for PC notebooks and don't work overly well with Mac`s if at all. One cooler that does work efficiently is the Moshi Zefyr 2, as it`s principle of cooling is specifically designed for Apple portables, by blowing the air horizontally across the base of the computer, however don't expect miracles.

    A cheap USB fan can achieve the same if strategically placed, not as elegant mind, nor as easy to put in your notebooks case :p but they do help to reduce case temperatures.

    You can use software to override Apple`s own cooling algorithm by manually taking control of fan RPM and setting up power profile presets with SMC Fan Control 2.4, or here with UltraFan which allows you stipulate a preset temperature and the software will automatically raise and lower fan RPM`s to keep the system at the predefined temp, which i personally feel is a far more elegant solution. At the end of the day you want to control your system temperature, not your fan rpm`s. For me SMC is now pretty much redundant with the latest release of UltraFan having manual control of the fans RPM, and subsequently i am starting to uninstall it from my own Mac`s. SMC FC is a great app, however although it`s recently updated, functionality is limited compared to some newer apps, equally SMC Fan Control is rock steady stable and a finished product.

    Strictly speaking Apple`s own cooling algorithm works, albeit at sacrifice of increased temps for quieter operation. This has always been the Apple way and is really nothing detrimental to the system, i have one MBP from 2008 all original barring a recent fan change that has an uptime of over 30K hours. The latest MBP`s need less assistance in remaining cool; for some it`s simply disconcerting the heat generated and transferred to the case, although it`s perfectly normal as the aluminium acts as a heat-sync. i have to deal with elevated ambient temperature so at times a software solution is useful. Apart from the passive cooling the Mstands bring they also offer a very sound ergonomic solution. A passive cooler and UltraFan will maximise the cooling, there is little else you can do short of reducing the ambient temperature or the system load. If I know i am going to push a system i will close all apps that are not essential as this can and does make an impact to system temperature.

    High temperatures in general is not overly harmful to your systems, what is far more detrimental is thermal stress, when temperatures rapidly fluctuate by significant margins in short periods of time. Anyone striving for great longevity should look to minimise rapid temperature changes.

    The old adage still applies; it`s easier to keep a system cool, than cool-down an already hot machine. This being said it`s not strictly necessary, equally it`s nice to know that there are options for reducing temperature out there.

    Thanks guys, the UltraFan app really did the trick. I can actually hear fans working, now going at 6000 rpm under load. The MBP still gets a bit hot, but it's much more tolerable. Not to mention the rpm goes back down to quiet Apple default levels when under regular use.

    As everyone mentioned, heat is always present on our MBP's. Mine is lamost always on an mstand and I really don't feel it, I would not be happy with it if I used it on my lap or soft surfaces often.

    Keyboard covers and stands do help but do not block the vent below the display, that is the main are heat is released.

    I also run hardware monitor so temps are always visible
