Mac Pro :: Samsung F1 Oscillating Humming?
Mar 15, 2008
I replaced my main drive, the 320GB with a 750GB Samsung F1. It seems to work fine. However it seems to have set up some sort of sympathetic vibration in the Mac Pro, which sounds like Hummm Hummm Hummm. Where as all the other things that cause noise in the case are a consistant and steady tone, this one is not. It's driving me nuts. Is this normal to be making this noise? I've tried it in different bays and it makes no difference.
UPDATE I've taken all the drives out except the F1, as I installed another DVD drive and three HD's and the noise has gone, so I'm now going to load each drive and review.

sometimes but not always my mac pro starts to hum.
its on hardwood floors, and if i just gently move it a nudge, it stops humming.
is it the floor or an issue.

What causes a harddrive to make a humming type vibration. Is that a drive getting old and need to be swapped? its annoying because my mac pro tower is silent otherwise.
The noise started about a month or so ago but I had this drive for a few years now.
If the machine is on after it was a sleep for about an hour the noise dissipates a little.

Last week I recieved my 27" iMac i7 2,93GHz with the 2TB Hitachi Drive.
I ordered this drive because it was said in this forum that this one should be silent.
Now, during access it is not really silent, but thats no problem
What bothers me more is, that there is a permament silent hum. An I can fell this vibration even on the stand (hopefully this is the correct term, I am from Austria, so english is not my native language).
And this vibration is also forwarded onto the table, but it is not really feelable on the table.
So my question is: Some say that their iMac is "dead silent". Mine isn�t, I also can here the fans silently, but that doesn�t bother me either. But this humming is somewhat distracting or annoying.
Maybe I am just to "picky", but do you really have iMacs which are almost inaudible?
Because I do not have any other problems I am not sure whether I should ask for a replacement.

I just purchased 2 1TB Barracudas and upon installing them (bays 3 and 4) I noticed a faint but definitely audible (and aggravating) humming noise that comes in a cycle of about 5 seconds.
It sounds identical to this video (made by someone else, but with the same drive) but my cycle is a bit longer:

I'm wondering if this is an issue with the drives or my installation? I mounted them tightly. I tried staggering the new drives with my old drives in terms of bay order to no avail.
Has anyone experienced this? The price on these drives is killer ($129) but I'll be returning them soon if I can't kill this noise.

My Mac Pro 8 Core 2 x 2.8 GHz Quad-Core Intel Xeon with Leopard 10.5.8 started making a humming noise about a month ago. The humming noise is very consistent in pitch and is always humming whenever the computer is on, except for when sleeping.

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?

After returning 4 21.5" imacs with yellow screens and hard drive noise, I decided to try a 27" and finally a beautiful screen with no problems, no hard drive noise. I was very happy...untill I started hearing a humming noise that sounds like it is coming from the power supply. The noise stops when I put it in sleep mode. I tried a bunch of things to determine if it was the fans or hard drive and that was not it. I am pretty sure it is the PSU humming all the time. This is the first imac with a perfect screen and now it is humming. I am so frustrated.
What should I do? Have the power supply replaced or return it for another one and take the chance of getting one with a yellow screen? I am still within my 14 days of original purchase date.

My Powerbook G4 recently started doing the HD clicking and squealling noise. So I changed the HD and everything worked great for about a day. Now there is a new Humming/Ticking noise coming from the area where you plug the power supply in.
If i tap in that area, it will go away for a couple minutes and then it comes back again. Sometimes it will just go away on it's own for a few minutes too. It doesn't change if I unplug the power or anything.

I bought iMac 27" from local apple store two days ago. Everything is fine execpt that there is some weird sound coming from the computer when the screen turns darker to save energy. Once I move my mouse to activate the screen, the sound goes away. I am saying the sound is so load, but it is still noticable and a little annoying in a quite room.
Update: I search "screem+humming+dim" and turn out actually a lot of iMac owners have this problem. Is it a technical issue Apple fails to resolve in general?

Yesterday I started up my MacBook Pro that I've only had for about 9 months. I immediately noticed that there was a barely audible buzzing / humming sound coming the inside of the laptop, most likely in the fans. I don't know how long this has been going on, and I really don't know the cause of it. So is this something I should be worried about (the sound is barely audible)? Or is this something that happens after prolonged use of the laptop?

There is a new humming sound coming from my parents iMac, I think it's the processor cooler but I'm not sure. It could be the hard drive as well, I just know it kicks up sometimes when there is a lot of activity. The problem is they don't do a lot on the computer so it scares them.
They are convinced that it is going to die because it's soo old, I think under two years, but this is the second computer they owned. The first was the first 20" G5 iMac that, instead of turning it off the correct way, they just unplugged from the wall outlet. Needless to say it died, but they think it was because their son in law used it too much. I try to tell them that it's because how they turned it off, but they didn't like their son in law, who is now an ex-son in law, so they blame it on him. Yes, I know, my parents are the last people to own a computer.
They also don't want to spend any money on their computer, so worse case scenioro, taking it to the Genius Bar without this computer being under warranty and having them replace the processor fan and/or the hard drive, what would it cost? I think it might just require a new fan for the processor cooler, but what if they need to replace a lot more?

..by the power unit at the back of the machine - where the power cord goes in.
I happened to be switching out displays at the back of my MP today. Could hear the fan at the lower back portion of the machine (as normal). but this time could also hear a very slight electrical hum just by the power unit -- is this normal (the hum) does yours have this hum?
I never heard it before. guess my head was never that close to it when the MP was on the floor. but since i moved it to the top of the desk my head is closer to it when I switch out the DVI ports
Trying not to be obsessive. I'll run before the white coats turn up by the front door

I purchased a 21" iMac a couple of months ago. Today it started making constant buzzing/humming noise. It's not really loud, but it is noticeable and annoying after a while. It stops if I put the computer in sleep mode or turn it off, but it starts back up the moment I turn it back on again. It sounds like it is coming from the bottom of the screen near the speakers. I have tried adjusting the brightness and volume, but to no avail. I also tried lifting the computer off the desk to see if it was just vibration, but that did not make a difference either.

I have a 2006 White Intel Imac and I recently replaced the Superdrive with a non apple Panasonic Superdrive Model: UJ-85J-B from a used Acer Laptop. The replacement drive has no sensor circuit board. After putting it back together there was a loud humming noise and I assumed it was the new drive but when I took it out and started the Imac without it the noise remained? Now I am thinking it is the fan just below where the Superdrive sits? I blew out as much dust as I could from this fan and around the bottom of the case and that made the noise just a little less annoying. It sounds like it is about to take off like an jet airplane?

There is a loud and really annoying humming & static noise when I connect my charger to my MBP. The humming only comes out of the headphones jack, and not the MBP speakers. This really cripples me in my work as I am a music producer.
Mp3 of the noise: [URL] ....

I've had my imac for under two years, and just recently I noticed it making an odd humming/buzzing sound at times. It's not the normal sound you hear when your hard drive is working hard, it's definitely different. It's not the speakers either, it happens whether they are on or muted.
My suspicion may be that it has something to do with the power. That's because I've been bug testing a mac beta game, and it often crashes my computer, and I have to manually turn off my computer by holding down the power button until it cuts the power.
Does anyone know why this may be and how I can prevent it/fix it?

My 20.5 inch 2.7GHz iMac is about a year old and has recently started making a low humming/buzzing noise from the top right corner, near the SuperDrive bay. The top of hte iMac feels quite warm when it makes the noise and usually stops if I hold my hand on top of the computer. Is this something I should be contacting AppleCare about?

I'm planning on getting two of this samsung monitor.

The main connection out of the monitor is DVi. So I'm assuming I need to buy Apple's Mini Display Port to DVI Adpater, which is this link. [URL]

Is there a adaptor that I can use to connect my UMB to my Samsung Series 5 LCD via HDMI, or do I have to just go with the mini display port adapter?

I just hooked up my MBP to my Samsung TB using a MDP to HDMI adapter for my HDMI cable. I choose the "mirror" option under the display window in system pref. The issue is that the menu bar on top is cut of from my samsung tv. Is there any solution for this? How could I fill the screen so that I can see everything that I would see on my MBP monitor?

Im looking to connect my imac (intel core 2 duo) to my 46" Samsung LED TV for gaming, movies etc... how to hook this up (with the least amount of cables, my TV is on top of a mantle above the fireplace, so cords are a hassle). The TV is HDMI/DVI etc...

A week ago I bought a new color-laser printer that fitted my shelves perfect. I wanted to print by wireless so I bought the Time Capsule and it has just arrived. But now i'm having a very hard time printing by wireless.
First of all i updated the drivers on printer and Time Capsule (TC).
Then i turned the printer ON and plugged it in to the TC.
Then i turned the TC ON and configurated it with the AirPort-tool (Newest Version). The TC is perfectly seeing the printer and i am having a perfect connection.

I thought it would be pretty straight forward connecting my mbp to my lcd samsung. I'm using a belkin hdmi to dvi, and after I connect and select the input on the tv, all I see is the original os x background on the tv. Ao at least I am seeing something and the cable seems to be working, but that's all I see. I can't get anything else to display. When I watch instruction videos people just seem to get the whole desktop with dash and everything to display right after connecting.

I recently purchased a 2009 Mac Pro (ATI 4870) and am using it with the 22" Samsung SyncMaster2253LW monitor. I'm no monitor expert, but a lot of videos etc look highly pixelated etc. The Desktop and everything else is fine. Most of the options aren't accessible esp the contrast. I have it connected via DVI and VGA :P Does DVI or VGA mark a major difference?
I know the monitor is a bit old. It's dynamic contrast is 8000:1. Is it purely because of the monitor that the graphics look so cheap and pixelated? Even the DVDRips look quite cheap.
Do movie quality improve cause of the graphics card? Ofcourse on my compact 13" MB, DVDRips look brilliant. Should I get a better monitor? I feel my poor 4870 is feeling unused.

I just purchased a Samsung Series 4 Model 530 monitor, 32 inch, with a resolution of 1920 x 1080p. Can this effectively be used as the main monitor for my new Mac Pro laptop? I can NOT find this resolution in the prefs anywhere, and do not know if I can really use this monitor. I work in print design, and as a result, I am always viewing typography in great detail.

My wife and I have never had a TV and have always watched DVD's on our not-even-one-year-old MacBook Pro and after moving into a house, yada yada yada, we finally purchased a Samsung LN46C630 LCD TV.
Now, we aren't ready to buy a Blu-Ray player yet so we want to continue to watch DVD's on our MBP and hook it up to the TV and watch it from there.
