    Hi I'm new here and I recently moved from windows to a mac which I'm loving the moment :D

    But I have one concern, I was playing world of warcraft tonight which no applications running in the background and saw my temps were fluctuating between 86C and 94C and my fans were 3000-4000 rpm

    Will this heat damage my macbook air, I stopped playing incase I was damaging it as I've only had it 3 days.

    Also would it be worth investing in a cooling mat to add that extra coolness to the underneath of the macbook?

    Your Mac is not overheating. 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.

    My 2012 MBA runs very hot anytime anything requiring extended use of graphics. It is either warm or very hot in the upper left. It's normal. Just don't expect these things to run 5+ years.

    No first of all those readings are never accurate if your mba really got as hot as you say it would shut down plus these new cpu's are dual and quad core there going too get hot under heavy stress but no harm will come to your mba plus they throttle down at certain temps and also i5 and i7 chips have turbo boost built in so when you bring up an application the turbo boost kicks in and when the puter knows it doesn't need the turbo it throttles back down your mba won't melt, explode or put you in outer space so don't worry enjoy your investment i hope this helps GOOD LUCK...........

    if u want to help it along, be sure the vents on the back are never blocked. Pop it up with something so the bottom gets more room for air flow. Use some kind of rigid, flat pad if it's on your lap.
