There is a fan problem on the Air!

I have the same problem. Nobody here knows how to fix it. In fact the only person that responded to my inquiry did not give me a way to fix it. Try calling 1800myapple. I haven't because you have to wait on hold like 20 minutes. This problem wasn't there at first. It was after the bluetooth update.

Just so you know - I'm not having any problems with my fan(s). They rev up and back down just fine. I've had my MBA now for a month or so. It's a week 11 production model. Seems like a good week for MBAs.

Perhaps is a bug fix. may be next firmware update it'll get fixed. Mine seems fine today. I even ran like three apps at the same time while downloading iWork using remote disk and nothing! Maybe it was a bug fix.

Have you opened Activity Monitor while the problem occured to see what program was causing heavy cpu usage? I had similar problem. Fans kicked in even when I was not using the MBA, although I had Mail open. It appeared that Mail was using close to 100% of CPU, again I was not using it, it was just open.
Somebody at this forum pointed out that this behavior may be caused by a preference setting in Mail regarding sounds to be played when receiving a message. I changed the setting and over the last few days I have not heard the fans.

I also find the fans somewhat irritating and unpredictable. One thing I have noticed: the fan reaction is much delayed. You do something that increases cpu load (say watching a web page with heavy flash) for a short time. Then maybe 10 minutes later the fans pick up, and it then takes 10 minutes to cool down again. The fans on my MacBook can also be hyperactive (disclosure: my previous PC laptop did not even have a fan, so I'm spoiled), but the reaction is predictable. If I watch a web page with heavy flash, the fans will kick up, but as soon as I close it, the fans will settle down again.

I bought my MBA 2 days ago. Ever since I opened it the fan was on at 6900rpm. I searched the net and found this.

Installed and the fan slowed to 2000ish immediately. Try it.

I had the same issue...fans going nuts for seemingly no reason. I've had the MBA since release (1.8Ghz SSD), and it was never this bad. Apple Store ran hardware test for 21 hours and everything passed. They said it was software related (oh, and the engineers were 'working on it'), so they downgraded my OS from 10.5.2 to 10.5.1, and guess what?

Problem fixed!!!

If you have an MBA, do all the updates except 10.5.2, and you'll be fine...if not, you have a hardware issue.

Hope this helps all those that were going nuts like I was.

Wow. I do not like the solution, if that is the only way. Downgrading to the previous update. Will they fix it in a future update?

do you guys fix this problem?
i just bought air about 3weeks ago~
i found the fan is so nosiey

how can i fix it~~~ it is hardware problem or software problem?
what should i do~~

Greetings.

Maybe you guys can try "Hardware test" first. Restart your MBA,press and hold "d" button. It will bring you to the "Hardware test" and follow the instrustions given. From here you guys can find out any hardware failure or not.

Hope it helps.

Chrees.

How is the procedure to downgrade from .5.3 to .5.1?

i agree with the title of the post. definitely fan problem.

this is my second MBA. still kicks up to 6200 under normal browsing or iTunes listening.

ATTENTION PLEASE! APPLE ENGINEERS!

I have same problem. MBA going crazy. FANS very loud and scratching noise coming out. Apple please do something to fix it. Though speed only ca 6200.
