Hello everyone, There is loud sound from the fan I don’t know from what, and what I have to change. Explanation: in the normal Mac laptops when you use browser there is no loud sound but if you open big app like photoshop etc. you will hear the loud sound till you close this app. But in my laptop I hear this sound from the fan even when I open just the browser and when I close the browser I still hear it. Please can you help me I need you to suggest if I have to change the fan? or to change another thing? And I’ve already changed my battery Please find attached video
Requested by @Dan : Screen Shot (at the morning when i start my laptop) at 10.37.56 AM
Screen Shot (when i start browsing US Today before loud sound) at 10.45.16 AM
Screen Shot (with the loud sound) at 11.03.29 AM
So i think the problem from the fan because its more than 6500, i am waiting for you.
Hello beautiful @Dan, this is reply for your (Update (03/14/2020)) i restart my laptop then i press D (long press) so the system moved me to here:
after that he showed me WiFis available, but me WiFi not there i don’t know why and i restarted my laptop again but still the problem, so i write it by myself :
finally after i connected my WiFi the system showed me this error (and this error i think you looking for):
Thank you in advance Mr. @Dan
The fan noise is normal in that when the system needs cooling it will push the fans to the max which is what it sounds like. So you need to figure out why the fans are running hard. I would recommend you do three things here. First you do need a better tool to even see what’s happening, so install this great app TG Pro that way you can visually see whats happening. For a reference take a snapshot of the main window (making sure all of the sensors and fans are visible) after you have turned off the system for the night when you start it up in the morning this is the cold level your system would normally run at. Now without doing anything on your system take another snapshot an hour later this would be the idle state. Now run your web browser hitting USToday, this is a pretty heavy site so your fans should ramp up just at the home page. Take a snapshot again and lastly take one with your normal work task. Label each so we can see what they are and post them here for us to see Adding images to an existing question The second action is to clean the internals fo dust. Get a soft small paint brush and a can of can’ed air. Follow this guide to pop the bottom cover off MacBook Air 11" Mid 2012 Lower Case Replacement carefully lightly scrub the surfaces of the case, logic board and fan blades with the brush, now with a few short blast of the can’ed air blow the debris away from the system. The third task is to clean out your old stuff on your drive. If you upgraded to an SSD make sure you have 1/4 of the drive free. If you have a HDD you’ll want to make a full backup and either run a defragmenter like Drive Genius 5 or wipe the drive and re-install your stuff. Update (03/14/2020) @boy4ksa - I was hoping for a few more captures so I could see the system working properly. For now it does appear the system’s SMC is working correctly and then it goes wacky! This gets into is the fan’s tach damaged? Or is another sensor failing forcing the system into Safe Mode. At this point I think you’ll need to run the onboard diagnostics to see if an error pop’s. Restart your system after it has failed and press the D key to enter into it. Let us know what you get. Reference: Mac startup key combinations
