    searched and i couldn't find a compile thread that shows temperatures.
    This thread is "NOT" meant to complain about if your system overheating or running hot.
    This thread will give users a comparing of how cool/hot our MBP's are running under various loads.
    This thread hopefully can identify faulty systems and users can get it fixed under warranty.
    This thread shall "NOT" have any discussions of temperatures (make your own thread with your problem)

    1. use format below
    2. Celsius only

    Model & Year:
    Temp. app/widget used:
    Cpu temp:
    Gpu temp:
    Fan speed:

    for example this is mine

    Year & Model: 2012 15 cMBP (lowest model)
    Tasks: everyday normal usage (safari, youtube) on hd4000
    Temp. app/widget used: iStat Pro
    Cpu temp: 32-37 C
    Gpu temp: 32-37 C
    Fan speed: 2000rpm-ish

    Year & Model: 2012 15 cMBP (lowest model)
    Tasks: while gaming (League of legend, lowest setting possible) on 650m
    Temp. app/widget used: iStat Pro
    Cpu temp: 60-65 C
    Gpu temp: 80-82 C
    Fan speed: 2300rpm-ish

    It's RPM, for revolutions per minute, not rmp, and this thread will get buried under the hundreds of "my machine is overheating, boo-hoo" threads which will pop up regardless, as nobody searches or reads stickies on most forums.

    Nice effort, really, but it'll simply go to waste.

    But since I bothered to actually open this post, I'll post my own results here.

    Model & Year: 2012 high-end cMBP
    Tasks: Reading this thread in safari, with mail, iCal, Word and iMessages open
    Temp. app/widget used: iStat Pro
    Cpu heastsink temp: 47°C
    Gpu temp: 47°C
    Fan speed: 2000RPM

    Gaming raises temps to 65-70 and 75-85, respectively, with fans hovering around 4000RPM.

    There's no need for that, as it won't be conclusive at all. Everyone has a different operating environment, different ambient temps, different hardware configuration and settings, different software workload, etc.

    If you're not already doing so, use iStat Pro (free) or iStat Menus ($16) to get accurate readings of your temps, fan speeds, etc., rather than relying on your sense of touch or sound. A forum member has posted a copy of iStat Pro that has been "tweaked" to enhance compatibility with Mountain Lion. You can download it here.

    The Intel processors used in Macs are designed to automatically shut down to prevent damage if they truly overheat. CPU Tjmax = 105C (221F), GPU Tjmax = 100C (212F) on i3, i5, i7 processors. (Source: Intel)

    Unless there is a rare defect in a Mac, most temps are well within the normal operating range, considering the workload being put on it. Websites with Flash content, games and other multimedia apps will put higher demand on the CPU/GPU, generating more heat. This is normal. If you're constantly putting high demands on your system, such as gaming or other multimedia tasks, expect temps to rise and fans to spin up accordingly. It's just your Mac doing its job to maintain temps within the normal range.

    It is also quite normal for your Mac to become extremely hot to the touch during intensive operations. The aluminum body transfers heat more effectively than other materials used in computer casings, so you will feel the heat more. This doesn't indicate that it's overheating and will not harm the computer to be hot to the touch.

    Your fans are always on when your Mac is on, spinning at a minimum of 2000 rpm (for MBPs) or 1800 rpm (for MBAs, MBs and minis). iMacs have 3 fans with minimum speeds in the 800-1200 range. They will spin faster as needed to keep temps at a safe level.

    If your fans are spinning up without increased heat, try resetting the SMC.
    (PRAM/NVRAM has nothing to do with these issues, so resetting it will not help.)

    The intake and exhaust vents are in the back of the computer near the hinge on all Mac notebooks (except the new MBP with retina display, which has intake vents along the sides at the bottom). The iMac vent is a slot on the back near the top of the computer. Make sure the vents remain unblocked to allow your computer to perform at its best.
