Just ran geek bench, no sound but the fan if I put my ear up the computer. I'm very happy with my MBP16
Got a tip for us?

PSA: Coil Whine on MBP 16
- Thread starter milhous

- Sort by reaction score
Mine is now constantly making a clicking sound when it's loading apps. And this morning I had the fan go bad and do a very audible sound even at 1500 rpm - at least that's gone for now. Already seeing myself replacing this thing several times until they'll offer me to buy it back.
What’s the specs?Just received my 16" with almost full spec and I have noticed coil whine in some situations. Bad.. really badNot sure if I want to replace. I also had coil whine in my 2018 model and I lived with it..
How do we understand production date

May I request a video during geekbench, I am sure i will hear Same sound with mine

You can watch listen and notice the most clear example of coil whine from 3:45 and 4:20 also experience this with geekbench 5 CPU test with putting you ear close to keyboard
I have 16 inches mbp 2,3/1TB and my device has coil whine which sources from turbo boost. I confirmed this because no sound on ssd speed test or gpu benchmark test. The sound only occurs if turbo boost is enabled during geekbench 5.0 CPU test. If turbo boost is disabled there is no sound.
What is the characteristic of this sound: very tiny, short time whine/buzz.
at this point if the mechanism of this sound is depended to vibrating Coils on motherboard due to voltage changes, how same devices with same motherboard have different outputs? How some people insist that they have zero coil whine???
the best way to notice this: start geekbench cpu test, wait for half of the test after that put otur ear close to keyboard, you will absolutely notice the very tiny electrical sound in every label/category for exp PDF render to face recognition or pass from face recog to particle physics.
If some one proove that there is no whine with video. I will congratulate him/her

You will notice during cpu benchmark test because it is not related with ssd it is caused of turbo boost

you will hear it during geekbench CPU test while passing from one category to other. Because it is caused from turbo boost

just watch 4:10 you will hear it during geekbench CPU test while passing from one category to other. Because it is caused from turbo boost. it starts in the second half of test duration and just put your ear a little close to keyboard.

because fan noise masks the coil whine...it is so easy to clarify if you record an audio very close to keyboard during geekbench CPU test in quiet room and share. I will tell every detail with miliseconds...
The point I'm trying to make is that I don't have any of the issues you are experiencing. My fans don't ramp up to insane levels where I can't hear a buzz. They'll ramp up to a moderate amount, they just won't go crazy.
Also my fans doesn't ramp up (too much) during Geekbench. Same goes when connected to 4K monitor. Fans stay silent. Definitely there are some bad 16"s. Apple's quality isn't the same as it used to be. Luckily I got the good one (MBP>2.4/5500M8gb/64gb).
I notice the noise mostly when I first start up the computer. It's not so much a whine as much as it's kind of a "crackling" sound.
If we are really discussing coil whine ...
Coil whine is caused by transformers or inductors vibrating due to the magnetic field they generate. For a normal power transformer that would then result in a continuous tone of 60Hz (50 in Europe) with a load dependent volume.
Where do we have inductors in the MBP that are switched at a frequency in the audible range?
I do not know, but some of the descriptions in this thread do not sound like coil whine to me.

Which is why I'm unsure if what I'm hearing is the same thing others are hearing and describing (I don't think everyone in this thread is describing the same noise). The phenomenon that I'm hearing is what you can hear when you scroll through your library on the Music app. This sound occurs on my previous MacBook Pro too, it's just quieter and harder to notice.
I found some dust on my MacBook Pro, seriously... computers make noise, show me a computer that makes no noise when you use it or stress it. You guys are looking for problems
I claim and insist that i can prove the sound if you capture an audio or video in a silent room and put your recorder close to keyboard. If you are self confident about this, i am waiting the record
dude could you please upload an audio that recorded n same conditions during geekbench 5 CPU test, i will be very happy
