Macbook Air Cooling...

How exactly does the Macbook Air cool itself?? There's no vent for air to come out from the fan on the CPU so I am a little confused on how this works. Thanks in advance!!!

See the plastic bit near the hinge? That's where the exhuast, and intakes, are located.

And heat can also escape via the keyboard!

Do you have a macboook air nearby? It's in that area between the LCD panel and the keyboard. It's the ONLY bit of black plastic you can see on the MBA (well, short of the KB, lol).

I've been reading about ventilation and so forth because I'm looking for a hard case and I wonder whether I should go for something official (Speck SeeThru is in Apple Store), or for something "different"

http://www.ebay.es/itm/Clear-Crystal...ht_1252wt_1304

There is quite of a difference in terms of prices but I don't want to damage my air by purchasing something that has not been tested by apple (products on their store are supposed to be sort of certified i've been told).

If the ventilation flow goes through that black plastic piece, this hard case from ebay shouldn't be bad right? What do you guys think?

thanks

The intake and exhaust vents in all Apple notebooks are located in the rear, near the hinge.

While heat radiates in all directions, no venting is done through the keyboard. The keyboard has a solid piece under it, preventing any meaningful air flow.

Easy answer..don't get one. They make the MBA look ugly - it's designed to look slender!

Unless you're planning to take it to a building site or drop it then you're not likely to damage it if you keep it in a case. If you want to keep it scratch free then check out Zagg invisible shield (or something similar)

Hmm, so why is my 11-inch MBA keyboard getting warm?

Could that be why my 11-inch MBA keyboard is getting warm?

"Warm" is rather subjective. My MBA keyboard feels warmer than the aluminum body. But it isn't warm enough to cause me any concern. My 2008 15" MBP would get really hot, to the point that you wouldn't want to put it on your lap while wearing shorts.

Heat radiates all directions, especially upward through the keyboard. That doesn't mean the keyboard has vents but rather heat simply dissipates through all the surfaces.

Sorry to hijack this thread. However the black strip which you see under your mba is it normal for it to move slightly to the left and right?

Yes. Slightly. Sometimes, at least in the case of my 2011 11's, it may also be slightly off kilter at the hing edges. My 2013, however, is straight, but still moves just a little.

Doesn't move at all on my 2013 11" MBA.

I am now using it from the battery and it is noticeably cooler...perhaps the heat from the charger is radiating up when I use it plugged in?

I would be very surprised if that guy knows what we are talking about. It takes quite a bit of effort to move, as you and I both know, and its literally a consequence of the design. Every single MacBook Air I have ever used, worked on, deployed, or played with at the Apple Store has done this.

My 2013 still exhibits this behavior, and its not even a week old. I am reasonably sure this is standard operating procedure for this chassis. The MacBook Pro Retina's I deploy at work show this slight movement too.

OK, I looked a little closer. There is a slight gap on the right side between the plastic and the aluminum, hadn't noticed that before. So I see how it might be possible for the plastic to move, however I am not able to make it move by pushing it with my fingers or even by gently prying it with my fingernail. Why would I want to "take quite a bit of effort" to make it move?
