Macbook Air has started making a whirring noise

I have had my Macbook Air for about 6 weeks and today it has started making a whirring noise, it has been on for a fair few hours but is not warm to the touch so I don't think it is a case of it overheating. The whirring noise is coming from the left hand side of the machine. Any ideas what is happening or what to do?

As stated above, since you've only had it for 6 weeks, thats extremely unlikely, there could be a particle in the fan assy.


or the fan hub is defective, or contact the blades from the housing


Contact Apple for appt. for diagnostic on your fan assy. 😊

yes, its the fan assy.



Is it NEW from 6 weeks ago or USED from 6 weeks ago? ...possible debris in fan assy and its housing.


Dust bunnies etc

Your Macbook’s cooling system, including fan and rear vents pull cool air in from the back and (in the case of the Macbook pro) also from the left ports bringing this air around the processor, GPU, and heat sync and blow it out the back, as such your Macbook acts like a little vacuum cleaner of the air around you. If you use your notebook in a dusty area or around a lot of pet fur, this can quickly, even under seemingly ideal clean rooms, accumulate inside your notebook especially on the fan blades reducing its capacity for cooling and in a worse case scenario seize your fan due to caked on dust on the fan blades. Avoid very dusty areas or places where, over the long term you know fuzz, fur, or even smoke can enter into your Macbook.



Is it making a buzzing or scraping noise?


If you only hear it in a quiet room, that is normal.

noisy fan reasons:


A: you notice it more in a quiet room (the typical case) which is normal, all is AOK


B: fuzz and dust has caked onto the blades causing the fan hub to get off balance and make a buzzing sound.


C: fan rotor is going bad and making a whirring or buzz noise (rare).


D: Fan is spinning up due to excess heat from gaming, heavy graphics (typical, all is OK)


A and D are normal


B and C are not.


Do you use it in a dusty area or where there is a lot of pet fuzz? Laptop fans act like little vacuum cleaners and take in dust etc. from the ambient air around them.


If B and C continue for a long time (B is just a cleaning), they eventually cause the fan to either seize and/or die.
