    I got a 2011 13' MacBook Pro a couple of months ago and its been getting really hot from the beginning. I'm not even putting a huge load on the CPU. The Macbook will reach up 90 degrees and sometimes even more when Im just watching videos on Youtube or ESPN. Is this something i should be worried about?

    Really? Im really surprised that this is normal. When buying a $1200 Macbook Pro, you would expect it to handle playing some videos without reaching 90 degrees. I've had 2 HP laptops in the past and both of them could handle flash without burning up like this and the price was about half compared to a Macbook Pro.

    I'm also a newly converted mac user and have noticed the fan on this spins faster than jet turbines. It's nothing to worry about at all. Just be sure to not leave your computer running on a soft surface like a bed, otherwise the hot air will suffocate it (like any laptop really).

    I don't mean to be rude, but this topic comes up here far too much. The 13" Macbook pro has a very small chassis which is made out of Aluminium. Since it is not made of plastic the chassis will act as a giant heatsink to better dissipate the heat across the machine. Even if you don't feel it, most laptops do operate at these temps especially when gaming.

    ^^This. 90* for the CPU is actually normal - my non-Apple i-series laptops get just as hot.

    One factor to keep in mind is that Flash is a resource hog on Mac OS.

    if u want to try something u can try replacing the thermal paste.

    Yes. Someone needs to make an official "My macbook pro is really hot, why?" thread on the front page where everybody can complain.
    I think for every five macbooks sold, two of them will end up being talked about on this forum for their overheating.
    Its totally normal.
    Remember that your HP notebook wasn't made out of aluminum. Which is a conductive material.

    Also, a note to prospective thread-starters. If you have a question that you think might have been talked about before, Then try the search bar first.

    It won't help any more than the "Which Mac should I buy" thread does.

    With that logic, given that it acts as a giant heatsink, the overall temperature and thereby fan noise should be less.

    To the OP: yes, this is normal.
    The MBP is very quiet in normal operation and Apple allows the fans to be at low speed up to a high temperature than IBM does on my thinkpad, but video (Skype, Flash) consume a huge amount of CPU power on the Mac platform.

    My Thinkpad (2007 T60 model) is noisier in normal operation due to the fans, but the noise and temperatures don't increase as much playing video as they on my 2010 MBP

    i dont have a MBP but my mac mini idle at 46c and full load at 64c, 90c seems way too hot in my opinion.

    MBP late 2011 is way too hot

    Hello everyone! I bought my MBP late 2011 with Lion last year and I've never been concerned about the heat until I used someone's mid-2012 model. There's a difference like night and day! My is the 2,8Ghz i7, the other MBP was a 2,5 i7 (newer architecture, though). I ran the exact same app with the exact same settings and the difference was remarkable. I ran Track Mania Nations Forever through PlayOnMac (I know this is not the usual program that Mac users will use, but it's the one that reproducibly heats up my Mac so I used that for comparison) and while my "old" one gets to 95°C within seconds and the fan runs at max rpms, the newer one doesn't really care. It gets hot, too, but not as hot and not as loud as mine. Rpms were around 4500 or so, CPU temp was 74°C I think.

    I believe the problem is Sandy Bridge.

    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 good to know that there are options for reducing temperature out there.
