IMac :: I7 27" Vibration Noise Normal?
Dec 16, 2009
I wonder if this is normal:
My iMac 27" i7 with a 2TB Hitachi disk seems to vibrate. It is so strong that it also makes my desk vibrate a little. If I hold tight on the desktop, it stops. However, the noise/hum is clearly audible when I put the iMac on the floor, for example.
Apple is happy to replace it, but am I too picky? Anyone else with the same?
(FWIW, I'll describe the noise as if you mount a hard drive in a cabinet, and it isn't really fastened/isolated well enough.)
I tried the smcfancontrol and checked the fans, and its not them, the noise is constant even if I set them to max or min. And it disappears completely when the disk has spun down.
My Macbook Pro, Macbook, or other apple hardware I got with a HDD does not make this kind of noise.
How silent is your iMac compared to your macbook/macbook pro?

Just got my 27" stock imac from an online retailer today. 3.06Ghz c2d etc. and absolutely love it except one thing. The HD seems to be much louder than my 24" imac that was basically inaudible. This HD on the 27" is a Seagate ST31000528ASQ 1TB, that seems to have an almost constant low buzzy, vibration-like sound that you can hear on the top right in the back when I don't have music playing? Anyone else experience this? Is this normal and is there any way to make it quieter?

I have the new 2.4 aluminum macbook and today for the first time I started burning cds and I noticed the whole computer vibrates pretty strongly. Is that normal? Also if i pick up the macbook and move it slightly while its burning it makes a weird noise. Is that normal also?

rite as some will already know i have took back my 27" iMac a total of 6 times and now i am on my 7th (4th one had screen issues), after actually accepting the "belly rumbling" "popping" noise and just getting on with the i5 experience, i thought i would actually contact Seagate direct on the actual matter for the rest of people on here who have doubt about there seagate hard drives.So i ring the operator i told him the whole story his first reply was sorry we dont support apple hardware! my response was "respected but the hard drive used is a seagate product"! he then replied saying sorry sir i misunderstood and quickly responded how can i help. I then repeated the problem and he asked for the HDD serial number, i was then very specific on the the noises we are all hearing and he made me repeat what i said a good 3 times so he had a very good understanding (in other words he did take this all seriously) he then said he was going to talk to the relevant person and put me on hold....10 minutes later he's back on the phone and he again asked me a final time! (ffs) to explain the noise he then quickly said in response the hard drive is supposed to make that noise. he named it the barracuda in seagates terms.

My brand new MBP 13" vibrates.
It is a subtle kind of vibration, notable only as a ticklish sensation on your palms when resting them on the case, rather than a concrete, strong up and down shaking.
I wouldn't even mind, if my wooden desk didn't pick up the vibration, acting as a soundbox with an audible, deep humming noise. You probably need good ears to hear it, I only do in a quiet room (like, my home desk...). After a short while, the deep humming is joined by a subtle higher-pitched humming. This is when there is absolutely no activity (no programs running, just an empty desktop). I am definitely not talking about the higher fan speeds accompanying increased processor activity and heat.
Now I heard multiple reports of MBPs doing this, but never found an objective conclusion: Is that something MBPs simply do (it's still better than most laptops)? Should I, *sigh*, return the damn thing?
In other words: Is there someone who could confirm that he or she has a 2009 MBP 13" (standard hardware load, cheapest of the unibodies) that has no vibrations whatsoever? Please note that it's subtle and I only noticed it after a while (but now can't stop thinking about it).

Just received the new Macbook Pro 17" with I7 option as well as the 7200rpm HD 500gb. The machine works great so far. However, there is a slight vibration I can feel on the aluminum in front of the keyboard and basically across the machine, though when I moved it from a glass table to a wooden desk it was much decreased. The machine is also much noisier than I thought it would be, though I did know when I went for the 7200 option that it might be noisier.
Is this normal because of the HD or I7 chip? I can return the machine and exchange it, but the anti-glare screen seems ok with no pixel problems, etc., so I don't want to look for trouble without a benefit.
Is it possible this is not the HD? (vibration and noise does seem to emanate from the left side-I believe it is a Seagate, ID starts with ST)

I noticed from the start that there is a noticeable noise to it, not loud. But noticeable. I can feel some vibration under both my hands when typing. I have used one of my friends white mabcbook and this does not have any such noise to it. I did opt for the 7200 RPM HD and now my question is is the sound coming from the HD or the fans? The sound has been on constantly since I first turned it on. Downloaded SMC Fancontrol and it's showing 2000 RPM on both fans, but that's normal isn't it?So is there anything I can do? Is this normal or did I get unlucky?

I am contemplating upgrading my stock 250GB drive in my 13" uMBP(June 2009) with a 320GB 7200rpm WD Scorpio Black:
[URL]
I was reading and some users have experienced unbearable vibration and increased noise, while some have not. I would live to be able to increase my HD speed, and am too poor for an SSD at the moment.
What are some experiences people have had with putting a 7200rpm in a 13" uMBP and would you recommend the upgrade?

A couple days ago I upgraded my mid 2010 MBP 13 stock hdd(Hitachi 5400rpm 250gb) to a new one (Hitachi 7200rpm 500gb 7k500). I am still amazed by how much faster and more responsive system has gone.
Some change in noise/vibration was expected, but now I am starting to get a bit annoyed by vibration and HDD noise.
Vibration gets on my nerves- the levels are nowhere high, but there was no vibration in my stock HDD. In addition, the noise of the system on idle has roughly doubled- both fan and HDD are humming at the same level.
The system is still very quiet, but I could not help noticing it anyway. Is this normal?
I tried replacing the old HDD and found out that the problems were not present with it (=I am not likely to have made some awful mistakes putting the hard drive in).
Then I tried tightening all the screws as hard as possible and putting some rubberized washers on the corners of the HDD to ensure snuggly fit. All efforts rendered no change. Are there any other methods to reduce noise and vibration?
Furthermore, I still have one day to return the 7k500 without any loss. Should I get WD Scorpio Blue 500gb instead?
I have read user reports of similar problems with WD SB 640gb drives as well. Since these drives are essentially the same, I would expect similar problems with 500gb as well.
P.S. Is there any chance that the stock HDD is slightly "downclocked" by Apple? It does vibrate a lot inside external cradle. Furthermore, I tested a couple laptops in the local Apple store. Both MBP 15" and MBP 17" where equipped with 500gb 5400rpm drives.
However, MBP 17" was vibrating much more than the MBP 15" (maybe MBP 17 HDD runs at its native speed to increase the performance. The increased size of 17" makes the vibration effects less annoying).
The stock HDD vibrates just like the current one until after 1-2s after the power button is pressed- as if some sort of regulation kicks in after that point.

I know it might be nothing, but just thought I'd make sure. I've been using an Aluminum Macbook for a few months, and it's been working super great, well, until yesterday, I'm not even sure if it's been this way the whole time, but it's been driving me nuts since this morning. The problem is, I've been feeling a little vibration around the entire trackpad area, especially on the right side, it's probably coming from the HDD (Factory drive 160GB), but I really don't like it. It's nothing noticeable, I mean you can't tell the difference until I've told you about it or unless you've been resting your hands on it for a while, but the point is, it does exist. Now my question is- is it normal? Was it there the whole time? If it's not normal, should I be taking it to the store? I've never even opened up the bottom, ever, it's been as it was on day 1. I tried listening to it carefully while giving it a little shake but nothing seem to out of place in there, it still feels as solid as new, but the bottom line is, I'm going crazy. What should I do?
P.S. It's got nothing to do with electricity cuz the vibration remains when I run it on battery.

I have had my Macbook Pro for about 3 days now and there is a weird noise coming from the inside. Mainly when I tap on the bottom right of the laptop I can hear a clicking noise. I can also hear it when I tilt it from side to side and it sounds like it is coming from the disc drive I was wondering if this was normal?

It happens more frequently when the computer is "thinking" but still chirps somewhat often when it is seemingly idle. Maybe its the processor or HDD?

I have a HL-DT-ST DVDRW GA32N Superdrive in my 2010 i7 iMac and I've had to reinstall the OS twice, because someone in the house kept messing with different files. Anyhow, the first time I installed it the superdrive was very loud, as it was the second time I installed it. It was like a loud vibration, as soon as I put the disc in. I have put other discs in and they are as quiet as can be. I've tested 9 or 10 discs and they all seem to be quiet. So I decided to put in the install disc one more time and it was quiet as well, no more vibration. Is there something wrong here or are these drives just noisy sometimes?

Specifically the hard drive fan runs at 1600rpm and the optical fan always runs at 1350 rpms.
Those fans run faster than my 2007 24" 2.4ghz iMac.
Somehow I figured with the cooler running ddr3, 9400M igpu and better cpu architecture that this new 2009 20" iMac would be dead silent because the fans would barely have to run. Or at least be less noisey.
But that's not the case.
Anyone have any fan speeds to report on new iMacs? Particularly the 20" model?

This is my first led-backlit display and the first big glossy display I have used. First of all, the display is amazing because of how accurate it is and I love using it. Then to the question:The display is sort of alive, stick with me i'll try to explain it as best as I can, english is not my native language
It kinda makes this very little brightness pumping that old crt tv's and monitors did. Same kind of effect but in a lot smaller effect, but you can sorta notice it's there. I have had none of those display image disappearance/flicker problems at all, display is working very well but I'm wondering if this kind of effect is normal with LED displays and does the glossy display enhance it/let more through? I'm thinking this might add to eye strain in long use but not sure(just like crt's did).

I have a new 27" I7 that appears to have the high pitch sound issue if the brightness is not at max or lowest. How "common" is this issue?
I do not need the perfect iMac (I have some gray banding and the 1TB HD grumbling and it is not a big issue to me) I just wanted to see if this high pitch noise is considered a defect and needs to be fixed/replaced or it is more common than not with the iMac.

My new iMac 27" (i3, 3.2GHz) is not so quiet as my previous iMacs -
I can hear a low humming noise! Not very loud, but I don't like it.
It grabs my attention...
It sounds like a fan motor or a transformer.
I can also feel a corresponding vibration.
Is this normal now? Does anyone else have this problem too?
Would you recommend to return/exchange this iMac?

I created a ubuntu live disc and tried it in my iMac. So I went into system preference=> start up disc and changed the boot order in order to test the disc. Now when I booted my computer this morning it automatically went to booting from the disc even when the disc was not in the drive. I thought it should have just gone back to booting from the hard drive. Does anyone know what I have to do in order to put the boot order back to mac hd?

I downloaded and installed Temperature Monitor and iMac Fan Control - mainly for observational purposes and not for toying around with the fan speeds and I've got some questions. Mind you, I haven't tampered at all with the fan speed settings, just installed Fan Control. Here are my readings (while browsing the internet with Safari and doing a chat via iChat):
Fan Speeds:
CPU fan (desired) 1300 RPM / (current) 1530 RPM
HD fan (desired) 2100 RPM / (current) 2099 RPM
DVD fan (desired) 1300 / 1298 RPM
Temperatures:
CPU Heatsink: 92F
Internal HD: 108F
Internal DVD: 95F
GPU Heatsink: 107F
Are these, under the circumstances, normal readings?

Safari locking up originally. I would get beach balls pretty often, and simple tasks like opening a new tab would take a long time. One day last week I noticed it took like 30 minutes to index in spotlight..just random weird things like that.Yesterday, I got home and the computer had the little loading icon on the middle of my desktop and was completely locked up. The computer wasnt doing anything other than running normal processes.

Newbie here, It has just come to my attention that my 27" iMac wakes up during the night. It is always put to sleep at night rather than turned off. My parents are staying for the weekend & sleeping in the same room as the imac, & mentioned this morning that screen turned on a couple of times during the night. I looked at the time machine back ups & found it had made 2 during the night.

after months of going back and forth I finally went with an entry level iMac which is perfect in every way. I think... I don't remember the start up time taking almost a minute to cycle from the blank gray screen to gray screen with the Apple on it. Tuesday and yesterday it started up much faster (at least 30 seconds). ere's my some of the hard drive info:
WDC WD5000AAKS-40V6A0:
Capacity:500.11 GB (500,107,862,016 bytes)
Model:WDC WD5000AAKS-40V6A0
Revision:05.01D06
Serial Number: WD-WCAWF5070764
Native Command Queuing:Yes
Queue Depth:32
Removable Media:No
Detachable Drive:No
BSD Name:disk0
Rotational Rate:7200
Medium Type:Rotational
Partition Map Type:GPT (GUID Partition Table)
S.M.A.R.T. status:Verified
The only thing I've done since Tuesday is add two songs in iTunes to test the cd-rom drive. I just ran the extended Apple Hardware Test and everything is fine. Given that my 20" refurb died within 3 months and I returned 2 iMacs prior that one, I'm a little nervous. Is this normal for a Western Digital hard drive to take nearly a minute start up from gray screen to grey screen with the apple?
