    I have the new 2012 13 inch macbook pro, it's great and all. But it's running so hot I can't even touch it. All I'm doing is web surfing and watching videos on chrome and it's going at 98-105 degrees celsius! Is this really that normal?

    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)

    If you're not already using it, iStat Pro (free) or iStat Menus ($16) will give you accurate readings of your temps and fan speeds, among other things.

    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.

    Although this are within the normal operating temperatures, they are the highest of the range. I suggest you take it to a Apple Store to get it checked. Even though flash player and other web browsing applets will generate heat as they demand quite some CPU power, this temperatures are well beyond what I would expect normal for that kind of use. Nevertheless they are still under normal range. Check for Chrome and Flash plugin version, having the latest will most of the times be best.

    Thats hot, but not abnormal. My old macbook reached 100 degrees Celsius sometimes. Avoid having it on the couch or in cases because they will bloke the fans in your mac. Also, theres an app called smc fan control which speeds up the fan speed of your mac. (wouldn't push it passed 4000rpm for the sake of your fans though)
