Mac Pro :: Rattling Noise Coming From Lower Intake Fan
Aug 6, 2010
Well, this problem that I thought was coming from the Radeon 4870 fan was really coming from the lower intake fan on my Mac Pro. The rattling noise was coming from this fan itself, and the Radeon 4870 was actually running silent the whole time. This is probably why people with the X1900 and older Mac Pros have been reporting the same issue. This has actually solved the problem for me, my Mac Pro is running silent now: I downloaded SMC Fan Control, then I increased the speed on my intake fan to max, 2800rpm. I let the fan run at max for one minute, I had an idea that this would cause the fan to work out the kinks if it had any. Then I returned the fan speed to normal, and the problem has been gone for the past 15 minutes. You can download SMC Fan Control 2.2.2 (Snow Leopard compatible) here: [URL]
While I use it, my Macbook Air will make strange rattling noises. It is quite audible and seems to be comming from the upper left corner (not the screen but the part the keyboard is on). Should I take it to Apple store?
I have a 15" MBP from around 2006, the one where they first introduced the new magsafe connecters.It's started to make a rattling noise which is very rythmic leading me to believe its the fans. Several years ago it started to make a clicking noise but that stopped and until recently it's been fine.
If it is the bearings on the fans or something like that, how much would that cost to fix?The machine is well out of warranty now.
Every time my trackpad is touched it makes a clicking noise/rattling noise. No, it is not coming from the speakers. It seems to originate from the bottom middle and the bottom left where I mostly click, but even when I scroll more upwards it makes the noise. This computer is in excellent condition and has never been dropped or anything.
I'll be using the Air and all of a sudden there will be static or electrical buzzing coming out of the right speaker on my 13" MacBook Air. It's about 16 months old.

Sometimes I lift and carefully move my 17-inch MBP a short distance to another flat surface without putting it to sleep mode, it starts making really loud mechanical noise when I put it down, so loud that people in the same room can hear the noise and I can feel vibrations too! What causes this? Where does this noise come from? Is my MBP defective?
Has anyone else had problems with an old G3 Pismo making an annoying squealing noise when plugged into a charger? There's a lot of noises mentioned in mac/apple forums but none of them relate to this one. Here's what it is not:
It's not coming from the screen or the fan or the speakers (it's under the keyboard). It's not low or slightly annoying (it is a loud squeal). It happens only when the power adaptor is plugged into the laptop.(it used to cease after I unplugged the power adaptor and plugged it back in three times; now that solution doesn't stop the noise anymore). It charges ok, and runs ok, scream or no-scream. It's quiet right now, but if I move the adaptor to another plug it will start again.
I was going to live with this, but today after an hour of operating quietly it just started again, and I hate to leave the house with this going.(it will scream whether the laptop is on or off. I have a really old battery and cannot replace it (I am currently staying in Mexico for the summer). Battery life is 45 min. I haven't tried pulling the battery out. That would be too easy.
This all started when I bought a replacement power adaptor (generic),after the original one melted down, but I could stop the screaming by unplugging/plugging it in again once or twice. Then I bought an expensive iGo adaptor, and it does the same thing.
I Did the PRAM and PMU reset.I can hear it over music or the tv. It grew lower in pitch today after squealing for a half hour. I'd normally not let it go on that long, but i was in the other room.Is my PISMO dying?

I am not sure how to describe it properly, but since 10 minutes ago, my trackpad on my 13"mbp has been making a weird clicking sound. Normally, it makes a click which is regular, just like the store units/how it should be, however for the last 10 minutes the BOTTOM RIGHT CORNER ONLY makes a weird longer noise which I cannot properly describe. its almost like a rattling noise, or something that sounds like its breaking. had this mbp since july this year, and i do have apple care (got it on student discount price!!
Just wondering if you know what the problem is, Or if it is going to be a problem/if trackpad may be breaking Or if I rang apple/took instore what would they do. Reason why I havent immediately took it in is because if MBP could get new processors soon, I could take it in after refresh in the small chance I get a new computer replacement..........
I have this problem with my macbook pro 17'' : noise occurs when I lower the brightness (the top left side). It's impossible to work at low brightness because of this noise.
I noticed in the past week that when I scroll through a webpage I can hear a clicking sound (similar to the one from the MM) coming out of my speakers? This also seems to happen when I scroll through my iTunes library but in this case it's a humming sound, when the scrolling stops so does the noise. I've tried muting the speakers but the sound is still there, has anyone else experience this before?
I have an iMac and it is making a constant clicking noise, like twice a second it is clicking (kind of like a slow moving fan sound but a more distinct 'Click'_
I have just noticed a weird clicking noise coming from the left hand side of my macbook. It only clicks when the macbook is being moved about or a sudden movement occurs. I thought it might be the HDD motion sensor but since its coming from the left hand side it's concerning me slightly.
Just got a new 2.2 MBP delivered to me yesterday. Didn't seem to have any problems at all until about an hour ago. I just began hearing a metallic "plink" noise every few minutes or so. Its not a click or a tick but more like a hollow plink. It comes at random intervals but sounds like it may be coming when the hard drive(?) or something inside the machine spins.
I bought a MBP 15 inch 2.66ghz brand new back in september. Since my purchase i have has several things that have been annoying the crap out of me.
Issues:
1. Clunk noise coming from HD, I have read some posts and installed Hdapm which reduced the sound a bit (i have the 320gb 5400rpm Fujitsu)
2. I believe becuz of the clunking (parking of the heads) causes my computer to stutter (mini freeze for like 1-2 secs) while using my MBP..
3. The battery used notify me that i had PLENTY of time to use even when i had below 50% battery life left, now (on Firmware 1.6) the battery tells me i usually have like 2:30mins of use when im at 85% or so battery strength left. and YES the screen is dimmed along with the keys.(i have calibrated the battery also)
I went back to 1.6 firmware due to the notion that various people have had better success on their harddrives working "better" with stock, or aftermarket.
I have a 7 day old Macbook Pro 13" 2.26GHz and sometimes when I open the screen I hear a click noise coming from the right side of the hinge it happens about half way open and some times when I pick it with the screen open it doesn't happen all the time it was doing it about 30 mins.
ago but as I type this its not doing it. Should I take it to the Apple store tomorrow or should I keep an eye on it and see what happens?
my macbook pro makes a slight ticking noise when i move it or tap it just a little bit it seems like its coming from the right palm rest any thoughts, i think it maybe the hard drive or something. oh yeah 2010 mbp 2.4 ghz 320 hard drive
Every time I start up or wake up my mac pro from sleep I get a large noise that seems to be coming from around the power supply. The best way to describe it is that it soudns like a buzzing sound or like one of those large elctrical transformers outside except not as loud. It goes away within 5-10 minutes.

First of all, my Macbook doesn't make ANY noise. Is very silent, but everytime I start a game, or I start to upload some files, the fans start to flip faster and faster and makes a big noise, like a rocket being launched. When I stop the game, the fans start to go slowly.
I have a Macbook Pro MC666ll/a. It is a core i7 15" with the AG screen. The issue I am experiencing is a random static noise coming from my speakers every now and then. If i have external speakers plugged in then the sound comes from the external speakers. Is this normal?
My Powerbook has been making a static-y sound from the back of it at random times. It sometimes won't do it all day, and then it will randomly start, and won't go away for a while. It's actually doing it right now! I've tried putting it to sleep for a few minutes, but it started back up again when i woke it up. There, it just stopped again! It can last from a few minutes to an hour, completely randomly! This problem started when I had Apple replace the logic board on the Powerbook a few months back, and numerous repairs later, nothing has changed, so I'm hoping someone here has an easy fix!
Is anyone experiencing a very slight clicking noise coming from their new 24 in LED? I just noticed a very slight clicking noise. I've had the monitor for 3 months now and just started to notice it today. I am running XP at the moment.
Earlier I noticed a faint noise coming from the top left of the iMac, a little 'hiss' like, but otherwise hard to describe. I presume it's the HD, but I'm not quite sure as diagrams show the HD being more-a-less in the middle. Perhaps the room has got quieter, but then again the concern is that the iMac has got louder.
I have noticed this buzzing noise (like crackling electricity of sorts) coming from the left side of the machine out of the cooling vent. I bought my IMac in 2010 and have not had any problems with it until now. I noticed the "noise" a couple of months back and it would show up here and there every once in a while, it was not annoying, so I let it be. Until this last time, when the noise was loud and annoying, I could not just forget about it. I am under warranty and called into Apple to see what can be done for this problem.
My mac book pro is making a strange crackling noise, coming from the right side, at first it was occasional now it's constant. It doesn't matter if the volumes on or off.
Today, my mac freaked out on me twice. I was watching something via Quicktime and all of the sudden the screen went black and green and started going crazy like it was twitching or something. And I got this loud noise coming out of my speakers. My MacBook is about 3-4 years old.
I have an aluminum macbook that is abou a year and a half old. It is making a weird scratching noise every few minutes. It sounds like I have DVD spinning in my disk drive and I am moving the laptop around. There is no disk in it so I am worried it's coming from my HD. Any ideas on what I should do?
I recently purchased a gently used MacBook. Running 10.5.8. The computer sounded and operating perfectly until I made the following software updates:
MAC OS X Update Combined iTunes QuickTime Security Update 2010-007 Remote Desktop Client Update Airport Base Station Update iLife Support Java for Mac OS X 10.5 Update 5 Java for Mac OS X 10.5 Update 8 Safari FrontRow Airport Utility
Now I have an annoying hum noise, that could possibly be the fan.I have run Disk Utility, but the annoying hum noise remains. Does anyone have any suggestions before taking this by an Apple Store.This was intended as a Christmas gift for my wife. Can anyone spare me the embarassment?
I have had my new pro since christmas, and it has been incredible. however i noticed from day one that periodically i get this buzzing noise coming from the left speaker - closest to the screen. is it the hard drive? what is it... and is it normal? sometimes if i tap the speaker area (next to the magsafe) it goes away.. and other times its pretty loud. i do NOT have applecare. should I purchase that as well.
