MacBook Air temperature

I started to notice that when I am skyping with video, with no other program running, the temperature is reaching 100C.
when I am canceling the video it goes to 65C.
also, when playing one flash video (like youtube) but keeping 3 other windows of youtube open but not running.it also get to 90c+
what is going on?
should I take it for diagnosis or it is normal?
when running noraml stuff like safari and normal videos. it doesn't exceed 70c, usally on 50c

Skype is terrible in general. My brother skyped for 45 minutes-1 hr using his windows laptop and he noticed it was starting to get really hot. The next day the laptop wouldn't turn on and he had it sent in for a hard drive replacement. Was it a coincidence? I doubt it.

I get the same problem with google+. Once the fans rev up the temps get down to around 90-95c.

FaceTime really doesn't have this problem. Apple should get their ass in gear and deliver its open standard promise.

Remember that your Mac has an overheat protection circuit built in. Should it reach unacceptable heat, it will simply shut down to prevent damage.

I'm getting this on my 2012 MBA. Particularly when watching YouTube movies in Flash. Switching to HTML5 in YouTube usually helps. I have seen temperatures at 105 degrees celsius. Fans go completely ape.

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.
