    I have observed my rMBP during I was playing Diablo III. The temperature is quite hight coz I set the game resolution second last of max out. The CPU hit 97 C. That was close to the CPU limit. Does anyone who is playing this game have the same experience?

    In my experience my CPU always hits the 100s celcius while doing something intensive like gaming or encoding. This is normal.

    I have observed that the fan is set to only spin faster once it reaches 95c, then when the fan speeds have maxed out the temperatures slowly drops and is steady around 80-90c

    I wouldnt worry about it - its normal

    If you are concerned with the temperatures and want to reduce them elevation of the rear of the machine helps, as sitting flat on the desk only reflects the head 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 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 cab achieve the same if strategically placed, not as elegant mind, 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 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.

    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 a short period of time. Anyone striving for great longevity should look to minimise rapid fluctuation of temperature.

    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.

    I don't understand why people worry about these things.

    Why on earth would Apple still be selling them if there was a problem with overheating?


    Oh and if you feel the need to use some form of cooler for your shiny new 2k+ machine, I'd suggest sending it back and buying an Alienware or some crap like that.

    You mean this documenting the 2011 MBA11 heat issues?

    Or how about this complaining about the 2008 MBA13's overheating as well?

    Apple never admits that it has problems with its design unless forced to by either a large outcry from the media (Antennagate) or sued through class-action (8600M GT, Magsafe).

    My rMBP in Diablo 3 (2880x1800 everything on low) maxes out around 94C.

    1) its strange because some reviews have reported temperatures only going to 60s and 70s for both gpu and cpu! Thats a significant difference!

    2) over time laptops get warmer due to dust setting into the system. it just happens. so the laptop gets warmer and warmer. if he is so close to being throttled, he is only going to see inferior performance from here on out. how is that not concering?

    remember the the 8600m and 8400m fiascos? millions of people bought apple, sony, dell computers that overheated due to poor factory dye that became a problem 6-12 months into the machines life. it was a horrondous fiasco and a lot of people had their laptops ruined because of it. Apple is only in control of so much. a lot of their parts come from different sources.

    Thats the thing with sandy bridge. Sandy Bridge had great GPU powers with its IGPU, but the cost was massive. it was a revision, but few could have predicted it would get so warm and throttle so much.

    when a computer throttles, its not like its not working, but it performs much worse than what you bought it to do. so temperatures matter big time in notebooks.

    Why is this an issue?

    Well, once the temperature hit in that level, my keyboard is quite a bit warm around 50-60 C. I didn't want to pay attention on this kind of thing. But it is really anoying. I want to prolong this machine. If you pay 2000 +, you don't want it die short.

    If your really concerned then you could play the windows version of Diablo on bootcamp and you would be able to disable Turbo on the CPU and install lubbos fan control, then the temps would only reach highs of 65-75c

    I posted a test i did here for Skyrim:

    even I just open 2 windows with flash videos in Safari, my fan and CPU keeps hot.

    I guess rmbp is not good to be considered as game machine. oh maybe you can turn up volume of your earphone, so you won;t get distracted by fan noise and cpu temp.:D
