    I'm hearing fan noise in my 2015 Air, which I wasn't expecting. It was a common occurrence with the 2011 MBP, but I thought that it wouldn't be an issue with this kind of drive. Any thoughts? Am I just being an anxious first-time parent of the Air?

    It's working fine and there's no slowing that I can tell, though it's somewhat warm to the touch on the bottom left. I don't have any more applications open than I typically do. (Could this be yet another nail in the coffin of giving up Chrome, that energy hog?)


    ETA: I should add that via the Activity Monitor, Chrome is at about 138.

    100% is one core full throttle. So no wonder the fan is on.

    Chrome has it own task manager under its windows menu. Kill the process which has gone wild or just restart chrome and shift+cmd+t to reopen the tabs, if you don't care which process was the cause.

    @MacBoook160: Though I avoid Chrome for known reasons, I use the machine intensively and I never heard fan noise. Ever. This is why I was astonished when one of the members stated that he could hear almost all the time the MacBook Air's fans working even across the room. The Mac gets warm sometimes but nothing else.

    It *was* Chrome. Grrr. This is a powerful and efficient a laptop as they come, I know that, and one rogue Chrome page...

    I didn't know that there were any mechanisms inside that COULD make that kind of noise with these new machines. Freaked me out, I admit, though obviously it's on warranty, and it could be fixed.

    I like Chrome's interface more than Safari, but given these ongoing issues...

    Yeah, all it takes is one small, poorly-coded ad, randomly displayed on one web page, to nuke your battery life, heat up the machine, and start spinning the fan [faster].

    It's a bummer.

    I'm pretty sure Safari is not completely immune to this although if the ad isn't on the tab that's currently active, Safari might throttle its CPU power. I wish there was a setting in Chrome for it to do the same.

    My fully loaded iPad Air 13" (2015) seldom makes any fan noise. Unless you are playing some intensive games you should seldom hear the fan either. Never used Chrome and have no plans to do so but that might have been your problem.

    When just working on a spreadsheet or document, is your fan still racing?

    No - I'm convinced it's Chrome. Now I realize why my poor MBP (circa 2011) was crashing so often every day. Because this Air is a more efficient and faster machine in every way, it's not crashing, but it did overheat last night to the point that I had a bit of panic...that I shared here as I quickly started to shut down tabs. :oops: The average energy impact was 1,3xx while the energy impact ranged from 138-178. Don't ask where MY heartrate was.

    Not to worry. You can't break your laptop by running some software.

    Even if you covered the vent with a pillow and put the laptop in a space blanket and ran SuperPi on it, it would simply turn itself off before it could overheat and damage itself.
