    Just a heads up. These get pretty hot. The fans can just keep it from meltdown it seems. I was using the 1.6GHz duo, and this is running about 15 degrees C hotter when maxed out. That's only when maxed, which is understandable.

    This should be no surprise. As long as it doesn't break down, and as long as the fans are of the quite variety (which they seems to be), it shouldn't be a problem.

    Now to see if I can make it shut down :D

    Note: off topic: BTW Lion is hosing a LOT of apps. Even 64 bit apps. Don't know why, but it may be a problem.

    Regardless of heat, how is performance on the i7 11"? I am thinking of getting one myself. I expect it to be hot but I want to run Final Cut Pro X on it. I've seen it run on an i5 and it looks okay. Any idea on the i7?

    What's with noise/temperature when you're just doing web browsing, so minimal CPU load, though?

    How did you get an i7 11 inch MBA so fast? I thought they were only CTO and they are just shipping now?

    Also, what apps is Lion messing up? I have only had one (Citrix won't recognize the new Java), otherwise everything is fine?

    I believe the 13's run hotter with the i7 so it's no surprise with the 11".

    I guess if you need to want to run FCP on the 11" go for the power i7, otherwise if heat and fan noise are a concern then get the i5.

    It's odd for me I always buy maxed out spec's in everything but unless you're a power user in the Air's the i5's may be a better choice.

    Some stores have them; picked mine up last night.

    My fans got really loud after installing Dropbox and it started syncing my 20+GB of data. It got pretty warm along the back edge, but not enough to be "too hot to touch" (unlike my '06 MBP, which does that regardless of load).

    Under normal use, I could not hear the fans and it was mostly cool to the touch.

    Some major city stores not only have the i7, but it's part of the line-up on display. The iPad displays had three models for the 11", not just two.
    Same with the 13". This is Chicago, at two stores in the city, but I imagine this is happening elsewhere.

    Apple has a no restocking fee policy in effect now, so you can buy one of these without the stress.

    The performance is much, much better than the previous top model. I was happy with that model but wanted more power as it struggled occasionally.

    Mind you, I also have the top model 15" (quad), and it's fans are no less busy than the Air.

    Note (little rant follows :D ) I AM having a bit of a problem with Lion. Frankly, it's driving me nuts. ALL my major apps don't even work. Maybe this is just bad luck. Also, it feels .....not there yet.

    I just got the new 11" maxed out (i7, 4GB, 256GB drive) and it does run quite hot on my Windows partition, although I'm pushing it to see how much stress I can put on the computer. I don't have as much software on OS X that would stress the machine.

    I've got Bootcamp setup to dual-boot Windows 7 (My drive split in half). I'm curious how safe it is to play some games on the side. I'm not looking for it to be a gaming computer, especially with its integrated graphics and condensed internals. I don't need max settings, but my previous 13" ran Starcraft 2 and Portal 2 fairly well. Would be great to slip in an hour of gaming here and there with the machine while travelling.

    If the 11" can handle the heat, I'd like to load up the Windows partition with some games like Garry's Mod, Civ V, Dawn of War II, etc. Right now though, I'm worried if it would generate too much heat.

    What temps are you guys getting? Idle I get low 40s and a heavy flash website I get 95-98. Temps in Celsius.

    Are you asking if its safe as in will the laptop overheat and break? It definitely should not, the laptop has thermal thresholds which if met will typically result in it shutting down long before any permanent damage could occur.

    It might definitely get hot as hell, but just keep it off your lap. If you're really worried grab a laptop cooler.

    Does the i5 11" have this overheating problem?

    I'm coming from a Powerbook G4 and the thing can literally burn you to the touch. The bottom would easily burn your legs on contact. Even touching the trackpad/top is uncomfortably warm. I was really hoping to get away from that issue with the new Macs, so it's scary reading threads like this. Things haven't improved after 6 years?...:(

    So comparatively, how bad is it?

    I haven't pushed pushed mine yet, but I did do some lengthy compilation that taxed the CPU a bit and pegged the fan at 6500 RPMs. The enclosure got up to about 38C or 100F. So warm to the touch, but not painful in my opinion.

    My early 2011 MBP 15's fan starts up when editing raw images, so the 11 256 i7 heat or fan should not be surprising, unless you like cool and silent all the time. I read about indexing taking place on new units that result in some low whirring fan sound.

    Isn't that the most important issue "how hot the enclosure becomes'" ? Who cares about how hot the chips get as long as the lifetime is 2 years so you can skip one update.

    I had a 1.4 GHz C2D and now a 1.6 GHz i5. iStat Menus is telling me I'm roughly 10 degrees celsius higher on average. It used to idle just under 40, now it's about 50, and sometimes 55. Definitely a hotter set of chips.

    Thanks for the comforting advice :) I know I'm perfectly safe within OS X, but wasn't sure of Win 7 may push it past a certain threshold that the system wasn't designed for.
