Hello everybody,
Since last night my MacBook Air's fan is making a LOT of noise.
I don't understand.
So, when I turned it on this morning, I decided to do an update of mac OS. Once it was done, same issue, and it's very slow to open internet or to do anything else.
I tried to do the SMC reset. Didn't work.
What else should I do ? Please help me...
Thanks,
Francois
MacBook Air, iOS 10
Hello !
Since, I didn't get any new replies, I tried and explore my laptop by myself. I realized this loud fan noise was happening because I installed Disk Drill 2 weeks ago. I uninstalled it and now the fan noise is all good !
So, make sure to look at recent software you might have downloaded on purpose (or not), it might be the cause.

Hi again,
Thank you very much for taking care of my issue.
So, my laptop is 3 years old. The version is macOS 10.13.4
I also downloaded macs fan control: the temperature of all the CPU are less than 75 degrees. See the screenshot attached:
I'll wait for your revert later. Thanks a lot.
Cheers,

hi
Try resetting the PRAM/NVRAM
How to reset NVRAM or PRAM on your Mac - Apple Support
if that does not work your laptop may have dust built up on the fans, that means that your fan and heat sync needs cleaning book an apointment at the apple store or take it to your local computer repair shop they will clean out the fan
if none of that works try Macs Fan Control as a last resort
Hope that helps, have a nice day 🙂
Hi
those temperatures look perfect, if you don't mind please can you answer the following
Is the fan at full speed all the time or just sometimes ?
Where do you mainly use your computer like do use it on your bed or in a hot car ?
and finally have you dropped your laptop within the last week ?
if one of your Mac’s temperature sensors is flaky or giving erroneous data then the controller chip will make the fan run at full speed even though the Mac’s temperature is in the normal range. turning off your Mac for 15 minutes could reset the temperature sensor so give that a try.
can you have a look at Activity Monitor to see if there are any apps using significant power

please try Apple Diagnostics to see if there are any errors and to see if the fan noise continues when in Apple Diagnostics

sorry this is taking so long
Thank you very much for the reply 🙂
Well, just tried the NVRAM / PRAM solution : still this loud fan noise.
I really don't believe dust built up in the mac. I was using my laptop all afternoon yesterday and at some point in the evening I used Lightroom and Photoshop and this loud fan noise happened. Why some dust would make that much noise all of a sudden...
I don't want to go to a repair shop and get charged a lot for something I could possibly do by myself.
Hi
its not the dust itself that makes the noise, the dust builds up over time inhibits cooling making the fan spin faster
just wondering how old is your computer and what version of Mac OS X/MacOS your using
if you download macs fan controlit will show you the temperatures of your computer if it says that the CPU is over 75 degrees C it is dust I open Macs all the time for various reasons to find that their full of dust if you want to do the repair yourself check out ifixit it has guides and a tool store the screws on the bottom of the MacBook Air are special
expect a reply in 15 hrs i need to sleep, sorry
Hello,
Thanks for taking time to try solving my problem.
To answer your questions:
Where do you mainly use your computer like do use it on your bed or in a hot car ?
At my desk: a flat surface then.
and finally have you dropped your laptop within the last week ?
Nope!
Anyway, I followed the instructions you previously gave me.
It didn't seem to have solved anything or to detect anything special.
So I left my laptop in sleep mode and when I checked this morning to see what's up, the fan is now silent as it used to be. And it's as fast as it used to be.
I have no idea how it has been solved and I wonder if it's really fixed and/or it's going to happen again soon....
I keep you posted if that happens again sometimes next week.
Thanks a lot !
Francois
Hello again,
Well, I just arrived at my office, turned on my laptop and here we go again with this loud fan noise.
Gosh, I thought it was solved but it would have been too beautiful to be true.
Any ideas? I don't want to bring it to a repair shop unless it's my last option.
Looking forward to reading from you.
Francois
Fan spinning at full speed, and the Mac running slow, usually means a temperature sensor is bad, and therefore it does that to protects itself just in case something may be hot.
To find out if a sensor is bad you can use Apple Hardware Test. Hold in the D key while turning it on, then follow the instructions given if any. After it has ran some tests I guess it will most likely say something like "There may be a problem with the SMC", which is the most accurate information it will give you, but at least it will tell you the problem is hardware related.
I am really confused, because this loud fan noise only happens when I launch Google Chrome, Slack and Spotify.
It used to be all good. Once I less use my laptop, it's fine.
But, the laptop isn't even hot, I read it's a hardware problem if the temperature is high, but it's absolutely normal temperature.
I'm really lost with what to do. Probably need to go get it analyzed at a repair shop, even though I wanted to do it as a last option... 😟
Hello! Thanks for trying to help me.
Already done that and it didn't show any SMC problem.
I might try again and attach a screenshot of what it says.
