    Hey guys,
    I have 2 MBPs 1st one ,2010 15 inch 2.5 i5, which I used in my stay in India for 4 years . I just casually browse the net or watch marathons of hd shows or movies and play games (5-10x a month for like 2-3hrs) from bootcamp. Whn I first recieved the MBP it worked like a dream ... fast, could keep up with what ever i mentioned above. In mid aug or sep of 2013 i started noting that it was slowing down and battery had too many cycles on it. I replaced my battery and discovered with the istats menu that my processor temp idling was around 60' celesus. I know that the operating temps are suppose to be in a range but in India with power cuts and hot as hell summers you really cant help it.

    And when I came back to the states I took my dad's 2011 13inch 2.73 i7 MBP since it was abused like mine with the heat, HD movies, games and etc. He just used to check his mail and browse the net. Recently I started converting some old home movies into .mp4 or what not to save on the HDD and get rid of the VHS and all . I also have a 2nd 20inch Dell monitor attached to it via Thunderbolt/HDMi.

    Now after all of this long introduction sorry... did not know what was relevant or not. I am noticing that the idle cpu temp according to the istats is increasing. when I first got the 2011 MBP the idle was around 40 C and now its around 48C. During the conversion of the (4hr or so/3gb)videos it takes about 2 hours time. And during that time the MBP reaches around 90-93C ( room air is around 78 F).

    I understand that video editing professionals use MBP to edit, convert, and other effects.
    My questions are:
    1.)How do they deal with the heat problem?
    2.)How long do they keep their MBP? ( thinking if its being used this constantly then it would decrease the life of the MBP)
    3.) I realize that my 2011 MBP doesn't have a dGPU but if i did a MBP w/ a dGPU would it help to increase the lifespan of the MBP.

    Thanks for you time, ( sorry for a long post)

    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 recent OS X versions. 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. For Flash-related issues:
