New Temp. Solution to CPU Whine

New temporary solution to CPU whine: MagicNoiseKiller.
This program was created by the same guy that created QuietMBP. This program is much better than QuietMBP. QuietMBP causes the computer to get hotter and forces the fans to go on and off (the mooing). MagicNoiseKiller does not use any processor power because it quits right after it loads. It does not get hot. It is the best solution so far to eliminate the CPU whine noise. Read more about it here: http://www.red-sweater.com/blog/108/macbook-pro-noise-i-believe-in-miracles
Download MagicNoiseKiller here: http://www.red-sweater.com/blog/downloads/MagicNoiseKiller.zip
With this program, I am extremely happy about my investment on this sweeeet laptop. It is silent as heaven.
Instructions to make it run at startup:
Go to System Preferences->Accounts->Login Items->Add MagicNoiseKiller

No way I'm gonna download the OS X update. I love MNK!!! I'm going to wait with the 10.4.6 download 'til MNK's updated. Besides, the new X update doesn't seem to fix the big problems. It's not worth it! I recommend MBP users (except for the ones who already did) to not install the new update until MNK supports 10.4.6.

New Macbook CPU Whine? Wasn't this MBP only?

I bought my updated macbook last week (Black, C2D 2.16 Ghz, 2GB Ram) and I noticed that the CPU whine that bothered me so much in my macbook pro is on my macbook as well!
The photobooth trick works.. but I wish this could just be eliminated once and for all..
Any suggestions? And does anyone else have it?

I have covered this topic extensively for close to 1 year now. I've come to a conclusion that all MacBooks exhibit this problem to some degree. I've had my Logic Board exchanged in hopes to get rid of the problem - but no way - its still here.
I've learned to deal with it in the following manner:
1. I'm rarely in a completely quiet rooms - so in most cases I dont get bothered by the noise
2. If I need to work in a quiet room - I use the Photobooth trick (force quit Photobooth - put comp to sleep - wake it up)
3. I got Windows XP on bootcamp - I do most of my websurfing with the new Internet Explorer - and as most of you know - the CPU doesn't whine under Windows.
The fact that CPU whine is completly eliminated when using Windows Xp means that the whole problem could be solved with a simple patch from Apple. However - Apple will not release any such patch until more people complain directly to them.

Analyzing the "idle CPU whine" issue

Hi All,
I have been waiting for a solution for the "idle CPU whine" issue since I returned my MacBook Pro because of the whine.
First of all, we need to filter out all the posts where a person says that he does not have the whine but has not heard a whining unit. So, we need to focus only on experiences of people who hear the whine or do not hear whine but have heard the whine in another unit.
Secondly, I think that the build week number has no significance on the whine issue. More interesting would be to have people sending here the last part of their serial number, which supposedly is some kind of configuration code, and stating if they have the idle CPU whine or not. Maybe we could get some new information out of that.
Do also state, if you have actually compared a whining and a non-whining unit. If you have not compared the no-whine opinions are useless as they are merely opinions without a reference to a faulty unit.

This was posted on MacFitIt today (www.macfixit.com)
" Mike, I thought you might find this reply from Apple regarding my contacting them with a noise issue with the MacBook Pro. I noticed that if I were to disable a processor core the noise immediately stopped and this is Apple's reply.
Eric"
Begin forwarded message:
"Hi Eric, I heard back from engineering and was informed that this normal behavior for the MacBook Pro. When the processors are idle a capacitor on the logic board will take on additional power loads causing the capacitor to vibrate, thus creating the noise. Turning off the second processor and/or using better energy saver settings reduces the load on the capacitor causing the noise not to occur.
For more information check out http://www.apple.com/support/macbookpro/. Please feel free to contact me if you have any additional questions..."

T420s - experiencing CPU whine that is getting worse

Hello there!
I have a Lenovn T420s with an i7-2640M CPU @ 2.80 Ghz, Optimus, and 8gb RAM. I got this laptop as a replacement from Lenovo since they severely damaged my other T420s while trying to repair the bezel.
This laptop is experiencing CPU whine that is getting worse and worse. There was no CPU whine at all whatsoever when I received this replacement in December, but now it shows up whenever I scroll up and down a browser window, click on a link, or do other normal tasks on the computer.
It happens regardless of if I am on battery or using the AC adapter. I've also read the other T410/510 page about the CPU whine and saw that the only fix was to get a new motherboard, CPU, and GPU. I also saw this post: T420s High pitch whine but it doesn't look like it has been updated for a while.
I have a 3 year warranty on this laptop, but I am hesitant to send it in without knowing if a good fix has been found. I already had a terrible experience with sending the laptop in for service, and had an even worse experience when the tech came on-site to work on it.
Anyone else with this problem? Has Lenovo come out with a solution?
Thanks!

Hi all,
I'm experiencing coil whine or "CPU whine" on my T420s. It's completely intolerable.
Rather than trying to describe this noise, I've put together the start of a sound album documenting it. Please listen: http://soundcloud.com/discostrings/sets/t420s-coil-whine
I suffered through 2.5 years with this problem on my T410. I sent it in once to resolve the problem, but it wasn't fixed. I figured the issue would be resolved in subsequents ThinkPad generations and I'd put up with it until it was time to upgrade.
But the whine on my T420s is much worse. It is impossible for me to use it in a quiet environment. But beyond that, some of the tones and clicking it makes are audible from feet away even in an environment with air conditioners running and people talking. I've tried (and recorded) every important combination of power settings. With all power management turned off in the BIOS and with the CPU limited to its lowest setting, it is ALMOST tolerable (but not quite).
I am willing to do whatever it takes to fix this problem--I do not mind parting with the laptop for a while. I would be happy to send it in for an engineer to look at and fix. I would be happy to take it somewhere. I would be happy to attempt to fix it to my own satisfaction if I am guaranteed it will not void my warranty. If none of those are options, I guess I'll send it in for motherboard replacements until I get a good one. But I'm going to have this fixed. Because this beautifully-engineered machine is impossible for me to use as it is.
As I understand it, coil whine results from faulty or low-quality coils or capacitors on the motherboard that resonate at different power levels. Unless this is from a rare bad batch (which I doubt because of my experience with my T410), this is a result of using bargain-basement coils and capacitors or not adequately testing the units from different suppliers. It's probably the matter of a few dollars or cents in manufacturing the computer. Beyond that, it can often be fixed with a drop of glue.
I put the recording album up to demonstrate that this is an actual problem, and to familiarize those who haven't heard it with the problem. I hope it helps other in diagnosing the coil whine.
Please let me know the best way to proceed to get this fixed. Thanks.

Is this the infamous CPU whine?

I recently got a new logic board for my MBP, and since then, I've noticed that a quiet whine coming from it. The MBP is a mid-2006 model; the logic board was installed by AppleCare a week ago. The whine only happens when the computer is not plugged in to the MagSafe adapter, and it's fairly faint; it's just barely bearable. Is this the CPU whine that existed several years ago, or is this just normal behavior? I thought they would have fixed the CPU whine problem on new logic boards by now. I don't think I heard this whine before in the 3+ years that I've had this computer. If I do stuff like scroll a page or run CPU-intensive tasks, then the whine seems to go away momentarily, which seems to be what the old CPU whine used to do.

Download SystemLoad and run that. See if you can get the CPU to "sing."

Is CPU "whine" a sign of bad things to come, or just annoying?

I bought a MacBook Pro for my wife in April. It's been good -- especially after the firmware update cranked up the fans and knocked down the temps a bit -- but it has the CPU whine/buzz/high-pitched noise under the keyboard. Like the MBPs of other folks, it goes away completely if you open Photo Booth etc.
My question is, is this just an annoyance or should we worry about shortened lifespan of the MBP or other problems? My wife is loathe to give up the machine if it's not necessary, despite the aggravating sound.
I asked Apple Care this question and the rep said it shouldn't be a problem -- as far as she knows. I didn't find that as definitive as I'd like. What do you guys think?

There are different power saving modes, they are labeled C0 (full power) through C4 (deep sleep). By disabling C4 the CPU only can enter C3 (sleep) and therefore consumes a little bit more power. I don't know if this increased power consumption is significant, but I guess you will barely notice it.

10.4.7 CPU Whine!!!! Please HeLp.. Newbie!!!!

Hi Guys..
I recently got a MBP (week 23) standard config.. As far as i remember i didnt notice the whirring or buzzing sound (known as CPU whine) until i upgraded to 10.4.7..
Well its pretty faint but i can easily here it when i am in a silent room n the thought that i have it now really makes me hear that n indeed this bugs me.. This is my first ever Apple product n first ever laptop (I am a newbie)..
I talked to a guy on apple support n told him about the issue n he said it might be the inverter buzz n is a hardware issue.. BUT i told him tht it cant be hardware as it goes away whn i turn on the photobooth or i do CPU intensive tasks, so it seems to me that its a software thingy..
So i have two quetions:
1) Is it a hardware issue or not??? If it is then i am gona send it back (ny suggestions on tht too will be appreciated)..
2) Other than the slight whine, ITS PERFECT, totaly NO ISSUES.. Jus wondering tht i turn the photobooth on to make it silent what effect does it make on the battery??? Cant figure out
Any help will be much appreciated as i need to make a decision tht whether i m gona send it back or keep it (plz provide suggestions on tht too if you can..)
Kind Regards

Hello Singh1699,
Yes, I already talked to one of the Apple staff in Ireland (I lived in Swiss) and they admitted that it IS the hardware related problem. They said the build is not somehow fully compatible with the core program of MAC OSX causing the noise from CPU and, quite a few times, with the power invertor.
You can search my posts here for more information about this issues. What I would recommend you to do is try to get a hold of Apple store, ask them for a replacement (you can even put the noise on phone for them to hear as I did). You have to be quick before your 14 days of return expires. That what I did and now I am waiting for my new one to arrive.
Hope this helps
Cheers,
James

CPU whine on macbook pro 13in

Hi, ive been experiencing the alleged CPU whine, and was wondering if apple will fix or replace my machine for a new one. Im under the 1 yr warranty.

fuad24,
Welcome to Apple Discussions.
They will fix it if they find there is a problem, take it into your closest Apple Store after making an appointment and they will look at it. Once they have then they will determine if there really reason to repair it.
Regards,

MBP Cpu Whine

Yesterday I recieved my Mac Book Pro 1.83 CTO 1gb ram and western spanish keyboard. The computer itself is incredible and I am very happy with it so far. The only problem I have is the cpu whine, which misteriously dissapears when I open photobooth and which dissapears when I open comic life and close it. After playing with my MBP yesterday for 20 minutes I already had a headache due to this whine. I called applecare inmediately and they prononounced my MBP D.O.A and offered to replace my MBP with a new one having to wait another 3 to 4 weeks and without any guarantee that the new one will not have this problem. They also offered to send the computer to austin for repair. I chose this option and am now waiting for the box to ship it to them. My question, is, have any of you successfully repaired your MBP cpu whine? If so what did they repair and how long did it take? After paying more than 2000 for this laptop I expect nothing less than perfect and this cpu whine will drive anybody crazy and I do not see why I should have to put up with it.Thanks!

you dont have to put up with it. after all the complaints about the whine im suprised people still buy it lol. if this was a PC machine with problems we would all be laughing at them. but its a mac with problems LOL are they laughing at us now haha.
PS mine is fine. but if yours isnt check the post below. there are like 500 responses so im sure one of them has good info for you. instead of waiting in here for an answer. this one is sure to have been answered in the other large post.

X300 + CPU whine + Linux + how to disable C4 state

Hi,
I also have this annoying CPU whine occurance when my CPU changes to C4.
As I have Linux running on my x300 (Ubuntu 8.10) deactivating Power-Management in bios is not an option because then I cannot adjust the display-brightness with the function-buttons anymore.
Is it possible to deactivate C4 with a shell script?
EDIT/ I had to reinstall gnome-power-manager after deactivating power-mgmt in bios, adjusting brightness now works again.
Yet, my question still remains.
Thanks in advance

C2D MacBook -- the CPU whine is GONE!

So, my black C2D MacBook has been up and running for the past three hours, and there is absolutely no hint of CPU whine!
That's my happy ending to a very sad tale of one bad rev. A MacBook after another...
This is the FOURTH MacBook I've had in the past six months. The first one was damaged right out of the box (misaligned case, and screwdriver scratches all over the bottom), so Apple replaced it. The replacement machine developed a really loud, grindy noise coming from the fan, and after two trips to the Apple repair center with no improvement, Apple finally agreed to replace that machine last week. The replacement had a nice, quiet fan, but plenty of CPU whine. Still not ideal, but I was resigned to live with it.
This morning, I learned of the C2D update. Fortunately, every time the Apple Store in Ginza, Tokyo, issued me a replacement machine, they also issued me a new sales receipt. So, I took the replacement MacBook I got last week to the Apple Store today, showed them my receipt for the latest replacement (indicating that I was within the 14-day return period), and asked for an exchange. I had to pay the restocking fee, which amounted to about $150. The way I look at it, I paid Apple about a dollar a day for the last five months to "rent" their rev. A MacBooks until the rev. B's were released!
Needless to say, I'm a very satisfied customer right now.
Whisper-quiet, super-quick and brand-spankin' new!
Black Macbook; Mini 1.5GHz (Late 2005); PB Lombard: PB 2400; PowerMac G3; Mac OS X (10.4.8) Blueberry iMac; iPod nano 4GB; and a Bill King bobblehead doll--Holy Toledo!

i would like congratulate you and to share your jubilation!
i have also had three macbooks since they came out after my very reliable ibook was stolen. no end of problems with my macbooks and just send the last one back a couple of days ago. only to log on today and find they have 2 core duo's now. So ordered one straight away. now i cant wait to recieve it :o) but am scared of what problems these may come with

Advice: CPU whine

Hi all,
I've noticed over the last couple of months that my beloved MacBook Air (purchased June 2009) has developed an annoying CPU whine, more commonly associated with the early MacBooks and some MacBook Pros.
Just to clarify, the noise resembles a static crackle and originates from the left side of the keyboard, in the vicinity of the 'tab' key. It is easily differentiated from the gentle hum of the system fan, located in a more central location. Varying the fan speed using smcFanControl doesn't appear to affect the whine, which also persists regardless of power source - AC or battery. Just as a troubleshooting step, the noise disappears with QuietMBP set at 80 or 90. Tellingly, the frequency of the noise varies with the slider setting in QuietMBP as well. Unfortunately, this has the detrimental side-effect of increasing system idle temperature by 7-8C. :'(
I can't remember whether my beloved has always exhibited this noise, which then proceeded to get louder and discernable over time, or if it followed the application of an OS update. I first noticed it when running 10.6.1 though, and it is beginning to drive me nuts.
I will have some time soon to get it looked at by an AASP. What I'm wondering then is if anyone has had any experience with this problem, specifically with their MacBook Air, but also in general. Any advice or insight would be muchly appreciated by a poor graduate student being driven ever so slowly to the point of insanity. Oh, let the crackling stop...
Yang

My Macbook 13" does it and has since I purchased it in late November. I've brought it to the Mac store, spoken to "geniuses" and scoured the net looking for other people reporting the problem, and hopefully someone with a solution. I have found little of the former and none of the latter. The previous comment seems to make sense to me though. What I can contribute is that it seems to me be related to power consumption. The whine actually starts when my Mac is using little power, such during idle moments or low CPU usage. Crank the CPU up and the noise seems to go so that it is less noticeable or maybe even gone. My theory is that there is a power saving feature that when it gets engaged produces the noise.
I refuse to install the quiet program because I'd sooner return the machine. This is a defect and if it cannot be fixed then I will hold Apple accountable to their warranty. If you ask me, Apple is aware of the problem and is not making it known. Call me a conspiracy nut, but I found this thread through Google. When I went to click through to it, it mysteriously was not available as if it didn't exist. Other threads on the discussions board worked fine. So I loaded the Google cached version. Today the thread is loading. Go figure.
Additionally, I am contemplating trying a SMC and/or PRAM reset but I'm unsure of any possible side effects of trying those out.
Please anyone with additional info post. The whine is incredibly annoying and interrupts my actually being able to get work done, thanks.

New factoid about the infamous WHINE

I have had my MBP2.16 with stock 1GB for one week and have noticed the CPU whine. It's not too loud, worse when on battery, goes off with photobooth, and mirror widget.
What I recently noticed is that when I open quicktime, go to preferences, and click the RECORDING tab, the whine starts up again. I don't know enough about computers to know what this means. Thought I'd throw it out into the community to see if any true gurus have any insights.
Thnx.
New Mac Convert x 1 week. Yeah! (whine or no whine)
i kinda miss right click though :^(

Curious as it may seem, I can endorse this - opening the Recording preferences panel in Quicktime makes the (high-pitched) whine come back (on mains power, screen brightness on full FYI). Damned if I know what'd make something odd like that happen... I guess if it's polling the iSight or the microphone it might be something to do with them.
(Please don't flame if I just said something dumb and obvious - I barely have time to read these forums during the week...)

Optimal Temps for sys, CPU and NBFan??

The Corecenter util that came with my new MSI MB reads:
CPU TEMP: 36C
SYS TEMP: 28C
NB TEMP: 50C
Are these ranges normal?

Looks like you're in a cold room The numbers are OK. The NB temp is meaningless as there is no actual temp. sensor. I prefer SpeedFan to CoreCell.

Core 2 Duo CPU whine.

Hi everyone.
I am close to purchasing a MacBook Core 2 Duo for my brother and I would just like to know how much of a difference there is in CPU whine between the Core Duo and Core 2 Duo MacBooks? Is the 'whine' in the C2D louder/more noticable or does it have less of an annoying noise?
Thanks in advance
Mark

I got Core Duo - my girlfriend got Core2Duo and both have the CPU whine. There is no difference in between the two - they're not too loud but get little bit worse with time. Apparently not every MacBook has this problem - so my advice to you is go ahead and buy one - and if within 14 days you're not satisfied, have it replaced or return it for refund.
Note that the CPU whine is not really that bad - that it will keep you from fully enjoying the computer. It only bothers me when I'm in dead silent room and browse the web. However - when I use Windows XP under bootcamp - there is no whine whatsoever. So when I need to browse the web - I do it on the windows side. Besides I really like the new internet explorer
Good luck with your purchase. The macbooks are a great little notebooks. I doubt that your brother will ever complain about the CPU whine - even if it is present. My girlfriend has never noticed it.
