    So i bought the new 15" macbook pro (non-retina) and I play a lot of video games on it. After a couple hours of Starcraft 2 the part of the computer closest to the screen gets very hot.

    When I play extended hours of video games, do I risk damaging my computer? Would it be prudent to invest in some kind of cooling fan, just to be safe?

    It's normal - you won't damage it.

    You could invest in a cooling pad or fan attachments but it will only reduce the temperature by a few degrees. It's not necessary.

    It's 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.

    Thank you that was very informative. Do you know of any good resources that talk about proper care of MBPs?

    You really don't have to do much, OS X takes care of most of the non-physical maintenance.

    As far as physical maintenance just keep it clean and open the back or dust out the vents yearly to prevent build up. Oh, and don't drop it of course!
