    Would like to dedicate this thread to the temps on the MacBook Air 2010 model.

    Just got mine today and wanted to do a comparison, just so I know nothing is wrong with my model (you'll get 14 days full refund, so prefer not wasting it).

    I can start out with some data I got from iStat Pro. Everything is in celsius.

    MacBook Pro with 4GB of RAM, 2.13GHz processor and 256GB SSD.

    HD: 47°
    CPU: 63°
    Northbridge: 57°

    Fans spinning at 2600RPM.
    The CPU is idling at 85%

    I am running on 10.6.5 - updating the system to 10.6.7 now.

    Is the MBAs temps as you were expecting, or does they seem just a little high at 60° - 63° when almost doing nothing? I have Chrome, Skype (just chat, no video) and Softwareupdate... open

    That isn't bad.

    I thought you meant 85% of the CPU was being used when the MBA was idle! Still, 15% is a little bit high. I've got a MB, not the air, but mine is around 3-5% when I don't do anything. CPU sits at around 45oC then.

    I don't pay any attention until I hit 70oC, then look to find out why. Even then, the 'safe' level is higher than that.

    The latest post in that other thread was back 3 - 4 months ago. I am not sure wether it's allowed or not to wake up dead threads on this forum.

    I'm making this post as I want to compare my temps, my fans and just to be sure my machine is as cools as it should be, and have maybe have some few questions answered.

    For example, would there be a huge heat difference in the 1.83GHz and the 2.13GHz processor?

    Yes, but they all still relate to the same 2010 MBA. I posted it for further reading for you, since the posts there have info related to your topic.
    As long as your topic directly relates to an existing thread, it's perfectly fine to resurrect a thread, especially if it's only a few months old, rather than a few years. If you don't find a thread that matches your topic, you're also welcome to start new threads. More info can be found in the Forum FAQ:
    Heat will be a direct result of what you have running on your MBA, not just what the configuration is. The more workload on the CPU/GPU, the hotter they get. Generally speaking, you don't have to think about temps. Your Mac knows how to manage itself without you doing anything. If temps are sustained at a high level for a period of time, the fans will spin faster to keep temps at a safe level. If temps get too high (around 105C/221F), your Mac will automatically shut down, to prevent damage.

    Isn't 67° just a little much for just browsing the internet, all ads disabled by using AdBlock and have no Flash sites open such as Vimeo, YouTube etc?
    The fans are spinning at 200RPM, so it's not a problem with the noise, I'm just worried for doing small stuff and suddenly turn on the fans.

    I am perfectly aware this is part of the computer, to cool down the components so it doesn't overheat / melt / etc. but still wondering if 63° - 67° is maybe just a little too much. Looking through the other thread, a 45° - 50° seems more normal.

    Not necessarily. To see everything running on your Mac, launch Activity Monitor and change "My Processes" at the top to "All Processes". That will show you all the apps/processes/widgets you have running. You can also see CPU utilization, memory usage, etc. Your temps are still well within the normal operating range. I wouldn't worry about it, honestly. You're better off looking at the web pages you're browsing than looking at your temps.
