MacBookPro 16-inch has current noise, cpu turbo frequency noise？

This is hardware issue and this issue cannot be fixed with firmware update - so there is two ways try to live with this or get money back. Two times made a request to apple about motherborad replacement - apple said that noise it is typical for electrical devices - so apple refuses to fix this problem

Turbo Boost boosts the clock rate on small number of processors when the rest are idle and the processor chip is comparatively cool. When many processors are in use, such as doing high-end work, Turbo Boost is not available.

If the noise bothers you, there are third-party utilities to turn off Turbo boost. The decrease in real-world performance is very small.

For software development, this means you will, wait a little longer for your single-threaded complies to complete, but it will be less irritating while you wait.

" It is not about cooling - the noise comes from bad quality inductors - `coil whine` it is not about cooling "

Then that would suggest Dell and Lenovo install bad quality inductors as well. Forums are constantly complaining about coil whine on these brands as well. I can't say you're right or wrong but I'm not convinced something is of "bad quality" when other major manufacturer's laptops exhibit coil whine.

Well then exchange it. Simple as that. My 16" MBP doesn't exhibit any coil whine so you may get one without sound. I've heard some on YouTube but they had to put the mic very close to the computer. It may be annoying to you but it certainly isn't loud. Come on!

If you bought direct from Apple after mid November, you have an extended holiday grace period until Jan 8 to return for credit:

then I'll have half the performance in my laptop when I use development tools - well, that's sound funny - I have to turn off the turbo boost to work without coil whine in the laptop I just bought.

I have with i7, my my colleague has with i9 - both our laptops with coil whine

You bought a very high performance computer in a Notebook format.

Using it a peak performance requires extra cooling and that cooling is sometimes loud.

I do not see any unconscionable design decisions there, just some very simple trade-offs.

"Going zero to 60 in 2 seconds is loud."

I didn't say every model has coil whine. The 13" machines are not high performance machines with dGPU's. The same with Lenovo's Thinkpad X1 Extreme. It's a 15" with a dGPU and an 8 core processor. It exhibits coil whine. The Dell XPS 15" also with a dGPU also exhibits coil whine. I'm only mentioning these other brands (especially the Lenovo) because they are expensive and Lenovo's X1 Extreme is just as expensive as the 16" MBP, so the amount someone pays will not dictate if coil whine will exist or not.

Seems to be that SOME here are shunning the fact that other brands like Lenovo and Dell that have incessant coil whine as well and should be ignored so we can focus only the MacBook Pro, which is ridiculous. The point is coil whine is common (for those that experience it) amongst Windows machines as well. Of course people here just want to make it about Apple as if Apple is the only one just so the blame lies only on Apple. Doesn't change the fact that coil whine is common amongst all computer manufacturers. It's silly to give other brands a pass and only place blame towards Apple.

No this means that apple instead of good quality control give some people macbooks without coil whine, But for Another people - with coil whine - so is this serious on you mind?(please dont give other companies notebooks examples - if i bought other company notebook notebook i would had same conversation on their forum)

I got the same thing using ML Enhance in Pixelmator Pro. While calculating I can hear an electrical buzz. Doesn't really bug me but I do think it's weird for a $5000 laptop.

Then return it or get it fixed by Apple. Never heard of anyone complain about coil whine saying they couldn't even tolerate it and couldn't get work done. Hmm.
