    Long time reader, first time

    I broke down and bought my Air last week and it has been great. I used to use a EEE PC and despite the price and the options that come with it, I just couldn't see using it long term. Not to mention the fact my fingers cramped typing for two hours in class taking down notes. The size can't be beat but I'd like to be able to type without popping pain killers.

    I was hesitent because on forums world wide those cautious consumers always warn, never buy first generation products. But I did. Meh!

    Now I'm starting to wonder if they were right.

    First thing I noticed was the clicking fan noise. I know the difference between high and low fan speed sounds and the sound of the hard drive. This is none of those two. When I have it on a flat surface it's fine, but if I tilt the machine forward or back I get this grinding/clicking sound from the fan like it's not sitting properly at an angle. My only other laptop I own is my MBP which doesn't do this (and is flawless by the way! So glad I forked over the cash for it - going on two years old and it still has better specs than some machines out there!) and I'm aware that most machines don't usually work on an angle. But when you're sitting in a chair you don't really focus on getting a leveller out to type on your laptop or surf the web.

    I tried searching the Apple forum and got nothing valuable (or as using the wrong search parameters!) and looked here and only found one thread on it. So far most people don't seem to be experiencing this (correct me if I'm wrong!) so I'm just wondering if it's something serious or I should just leave it and see what happens. Or just take it apart myself and wiggle the fan around.

    The second thing that annoys me is a crunching sound from the speaker. This is something I did look for as well but people have different adjectives for the sound so I'm not sure if it's the same thing or not. Mine seems to be an actual CRUNCH sound coming from the speaker area (arrow keys) that happens every few seconds. Doesn't matter if the speakers are 0 or 100 it still does this. I found a solution for it is having the machine run something CPU intensive, as in WoW for an example. With the speakers turned off you don't hear a thing despite the loud fan noise. Are there more speakers sounds than the one I get, or is there a whole forum dedicated to the MBA Crunch?

    Other than that stuff everything is amazing. I even get the core shut down during WoW and yet I don't get weird stuttering. I just get near or over single digit FPS during that time.

    Phew. That was a lot longer than I thought it would be. I'm still in essay writing mode please forgive me! :D

    Crunch is a good word for it. The issue is explored in another thread which includes the words "clicking sound macbook air" (I found it through google). Apparently it's normal and is acknowledged by Apple. Sometimes it goes away, then for an extended period of time it will do it every ten seconds or so. I'm trying to decide whether it is tolerable.

    if it's still in the return period, bring it back to the store and get it swapped out. as long as your problems are able to be reproduced you should be covered.

    Those wacky Apple product bugaboos

    A lot of Mac products have little idiosyncrasies like this, e.g. the hairline cracks in the Cubes, the easily scuffed/scratched iPod screens, the iBook hard drives that made a little "clink" sound about on par with the MBA's "crunch" sound. Sometimes these things become part of the product's charm.

    From what I've read here and elsewhere, the crunch is something that is common in MBAs, and might even be in all of them, just some people notice, others don't. I suspect if I exchange this one I will encounter the same thing in the new one, and even if I don't right away I've got to acknowledge it might come up at some point, and it might be realistically impossible for a few reasons to get something done about it (e.g. won't be satisfactorily "replicatable," or will be treated as "functioning within acceptable parameters" by whomever is covering its warranty) and basically I have to decide whether or not I consider the crunch tolerable.

    I wish I didn't have to, though. That, and the fact that merely playing a youtube video makes the thing run excessively, thigh-cooking hot, is making me wonder. It's mildly traumatizing given that, other than those two things, I love the machine to pieces -- anything else feels and looks ancient by comparison.

    My macbook Also goes full throttle with anything flash-based, so don't think that is a problem with your air, it is a problem with adobe's implementation of flash on macs.

    I have had two MBAs. The first had the same exact issue you are describing here coming from the speaker (under arrow keys) side. The second one did not have this issue but it suffered a faulty mouse pad button and extreme temps. (worse than MBP :eek:). I will get my third this Monday and hopefully it will be perfect.

    All are 1.6/HDD

    If you happen to live close to an Apple store, I would make an appointment to have them take a look at it. As a former employee of Apple I have seen this issue before and a replacement is always given. Some cases the fan could be defective part, or in rare cases, there is a wire, which happened to lay across the fan blade thus making the awful noises.
