Repetitive clicking noise on SSD Macbook Air

Recently, I opened my computer to hear a "rat-a-tat-tat" sound occurring for about 1 second, repeating every 4 seconds.


I searched the Web and came across a video posted on Youtube of someone who speaks in a foreign language, but is experiencing the EXACT same clicking sound, here is that video: http://www.youtube.com/watch?v=9bPrCCujLJ4 - best rendition of the sound is around :46 and :57 into the video.


This is a 13" SSD Macbook Air - there is no hard drive in this unit. Any ideas on what is causing this sound and how best to resolve it? It's really annoying. Thanks.

MacBook Air, Mac OS X (10.7)

Of course. The only moving part in the device is the fan. The noise eminates from the top left corner near the power connection. According to tear down images that is the location of the fan. It would appear to me the fan has failed.


I installed Fan Control 1.2, an app that among other things reports current fan RPM. I have several macbook airs. A normally operating (no noise) shows my fan RPM at all times. This noise-making macbook air consistently reports zero (0) RPM on the fan in the Fan Control app. So, the fan is jammed.


A few swift knocks on the case just above the fan, to the left of the "esc" key, and voila - the fan starts spinning at 4000 RPMs and temperature on the CPU drops precipitously. Nice. If the problem recurs or persists we will bring to Apple to replace the fan. In case others are wondering about this noise, there is the reason...

Hi there, not sure if i have the same problem. (edit: no problem anymore, "problem" solved, see text below)


here are the facts: mba 11'', may 2012, ssd hd 250 gb.


makes a clicking sound about four times an hour, sometimes more often. sounds exactly like a triple mouseclick with a little bit of hi-hat (the bronze cymbal) sound. it is definitely not from the fan and it comes more from the right side. Since i have SSD HD it is not a moving head or so. also, the sound doesnt sound bad or irregular, i am just wondering what it is. Aaaaaaaaahhhhhhh solved! just found out what it is:


my outlook for mac makes this noise when it has checked for new email and there were no new emails on the servers. since i use three servers, it makes three clicks when none of them have new emails, two, if blablabla...


thanks anyway, and maybe this will be helpful for somebody else.
