    I have my Macbook Air 2011 13 inch running Diablo III just fine. I'm surprised it looks alright on medium and great on low. But here is my question, my fan kicks into overdrive and is constantly running on high. I was watching the CPU temperature and it sits around 88-90 degrees C. So my question is, is it dangerous to play my Diablo III with the fan running on high and the CPU at 90 for a couple hours, or is it designed to run safe even while it's hot under full load. I just don't want to burn out my processor by accident just to play D3.

    Well within the temperature limits of the computer. You shouldn't be worried.

    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, GPU Tjmax = 100C on i3, i5, i7 processors. (Source: Intel) If you're not already using it, iStat Pro 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 they're 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. 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 for the information and the quick responses. I thought it would be okay but I figured better to be safe than sorry. I am excited now, I have a desktop and didn't buy the MBA for any gaming but I have been going to a friends house and bringing my MBA over and playing D3 will be fun.
