PowerPC :: G4 Fan Noise Getting Too Loud
Mar 14, 2007
I had the fans and HDD replaced in my 1.67Ghz PB G4 in January, but I think the fan noise is getting too loud again, plus the HDD randomly squeaks and squeals. The problem with the random squealing is that I can never start the camera on my phone quick enough to record it, and it is completely random! Does anyone know what the normal operating noise is for my laptop, or where I can find this out from? The normal fan noise is OK, but when the processor is under full load and the fans kick in to full speed, it sounds like the vacuum cleaner is on in the room. Should I take it back to the shop? It was 'repaired' roughly 2months ago.

I have an older 15" powerbook Titanium. About five years old now. Been working pretty well all five years, save for an external hinge I had to replace. Last night, the computer started buzzing from the insides, a buzzing reminiscent of a distant chainsaw. The program i was working in (firefox) just went to the pinwheel of doom and never recovered. I moved to the finder, which did the same. I forced booted. Same noise. Same problems. I can use programs for a few minutes, but then they pinwheel of doom and the computer freezes out.

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?

On my 13" MacBook Pro, the hinge makes a cracking noise on the right side of the computer (near the power button) when the screen is positioned all the way back.The entire hinge also makes a loud popping noise when I adjust the screen position. The screen seems very tight, and it takes a little bit of effort to move the screen, and when the screen is moved it makes the loud popping noise.
This is probably going to make some of you guys cringe, but sometimes putting pressure down on the top of the case close to where the black hinge meets to unibody enclosure seems to stop the popping noises. Putting downwards pressure on the hinge, or flipping the computer over and putting pressure on it that way, also seems to alter how much popping noise there is.
If I mess around a bit with applying pressure on different parts of the computer around the hinge, I can usually eliminate the noise. But, the cracking noise when I put the screen all the way back is still there.Any ideas what to do? It's not interfering with the operation of the computer, it's just incredibly annoying and this is only a four month old machine which shouldn't be creaking and cracking already.

I've noticed that most Macs have their fans run around 2000RPM, maybe 1300RPM. I was surprised to find that my CPU fan runs at only 500RPM pretty much all the time. However, it is much louder than those other Macs that have higher fan speeds.
Oh, and in case there is a misunderstanding, the fans are NOT running fast, and the temps are low. I've seen a few people complaining about this only to have answers about reducing the fan speed.

My G5 has been making more noise at start up. It sounds like one of the fans is making a grinding "rrrrrrhhhh" noise. My living space if very cold and quite dusty (warehouse). I notice it more on colder mornings ( inside temp 45° - 65°F ). Should I refrain from using my machine on cold mornings/nights until the heat is running?

I have a mac book pro, version 10.7.3. When I use quicktime player 10.1 to do a screen recording, and I turn the volume up, there is a loud screeching noise. The noise goes away if I turn down my laptop's volume or if I turn down the volume in the quick time player settings, but then my video no longer has audible audio.

I have a problem with my G5 freezing and it is preceded with by loud fan noise. I was wondering if the hard drive could be the problem? It had the problem with 10.4 as well as 10.5. It happens at startup most of the time and eventually lets me get up and running and stops being a problem.

For those of you that have the new imac, is your HD also pretty loud? I notice it constantly. Whenever I am browsing I can hear the ticking noise for a couple of seconds, this restarts every time I navigate to another page or simply by typing text like I'm doing now or scrolling down. I realize this is with all HDs, but this one is pretty darn loud. Does anyone else have the same issue?

I have a MacBook Pro 2009 with a 500GB drive (WDigital, I replaced the 160GB). I was using Perian to play mkv movies, and yesterday I downloaded Plex to try it out. But in both every time I play a Mkv file the fans start spinning, I think it's the fans or maybe the hard drive. But it's quite a loud whoosh all throughout the movie. Is this normal or playing a mkv file shouldn't make any noise at all? Should it use a lot of CPU? I'm using Leopard latest version.

Anyways, at the moment my mac is around 6 months old and just recently I am noticing that the fan is starting to vibrate- like when I type on the mac with my palms rested on the computer I can feel the vibrations. Now it is subtle but was not there before. As I am typing this the fan is at 2000 rpm. Also, when I am not out with the computer. I hook it up to my 23 inch monitor and a portable keyboard. Now when I do this I can hear a very loud noise coming form the computer while using it as a desktop. Almost as it its straining to use it. Its not so much a violent noise as it is that the fan seems to be over working.
I dont know if I am getting paranoid or if this is a serious problem- I have a 3 year warranty from bestbuy. The small vibrations I can feel form the computer seem to be like a small issue- however my friend beside me with the same model- her mac is silent and doesn't vibrate subtly. However, I am more worried about the louder noise it makes when I hook it up at work. Like when i put the computer to sleep I can tell a substantial noise different in terms of it going silent after I put it to sleep.

For lucky 15" i5/i7 owners: how silent are they? Does the fan come on at all? If so, after how much load? Any other noises? Hard drive?

I've just purchased a new Macbook. I'm very happy with it aside from the fan noise, which seems a little loud to me. Now, before I bring it into the Apple Store to have it looked at I just want to check and see if maybe I'm just being overly picky. I downloaded iStat, based on some Google searching I did on the subject and my fans are running around 2000 rpm, which I understand is normal. But in my apartment, which is admittedly quiet, I can hear my fan running constantly. It isn't extremely loud, but it isn't totally quiet either. I'm just wondering what level of noise I should reasonably expect out of my Macbook.

My Macbook Air has suddenly decided not to turn. I have tried the rebook using the left hand side keys 'shift/control/option & power' but still nothing happens. Every now and again when I try turning it on using the power button the fan turns on and is really loud?

I just received my new Mac Pro from apple on Saturday. This thing is a beast! I am planning on running apps from Final Cut Studio 3, Photoshop, After Effects, and others. 2.66 Quad/6GB RAM (OWC)/640GB HD/ATI 4870
I have a few questions.
1.) Is it normal for the Mac Pro's fans to make a lot of noise when you first start it up or wake it from sleep? My fans make a lot of noise for about 16 seconds or so.
2.) I am planning to put a second optical drive in it. Is there a way to eject only one tray at a time, or will it do both?
Now, I am selling my iMac for around $800 and I am looking at some upgrades:
An additional 21.5" Acer LCD display
A mini display port to dvi adapter
A LG blu ray burner
Two 1TB samsung internal HDs
A blu ray player (I do not have one yet)
Elgato Eye TV hybrid

My Macbook Pro 15" [2 GHz Intel Core Duo, OS X 10.5.7, 1 GB 667 MHz DDR2 SDRAM] makes a loud crackling, chainsaw-like noise from the upper left part of the keyboard. I think it maybe the fan but I'm not sure. I've attached an audio clip of the noise:

When my new i7 is on my usual desk (where iMac 24" white stood silently before), it sounds like a dishwasher. Or a plane engine. The low, loud vibrating noise drives me so mad I snap. It penetrates my very brain and makes it vibrate. It's audible from another room. In desperation, I raised my Mac and the sound stopped. I put it on the floor, and the machine is silent. Back on desk - airplane engine sound again. What the heck? My desk has been perfect for all my other computers, what's so special about i7?

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?Â

I just got a mac mini on thursday, went on a small trip on friday-sunday. When i came home to my sleeping mac mini and woke it, it made a TERRIBLY loud fan clicking noise. My old PB 12" made this noise after I had dropped it on floor from about 3 feet. I didnt drop my mac mini, i barely used it for 2 hours before i had to leave on my trip. The sound eventually goes away though, once the mini heats up a little i guess. So i'm pretty convinced it's the fan, but why would it suddenly do this?

every once and a while, when I am working on my MBA, i get a loud "ticking noise" in the upper right of my keyboard.It sounds like the harddrive is trying to think or something, but it only happens for about 5 seconds and it occurs even at idle if i dont do anything that requires the computer to use memory or access the cache, etc...

My 17" Macbook Pro was purchased on Feb 24th 2009 via telesales, so it's less than 6 months old. The hinge is very creaky and on the right hand side it makes a loud clicking noise when I open and close it, also the whole screen seems to creak, not just the hinge. The wall charger is in my opinion very loose, it was loose when I got it ( should have changed it then ), but I haven't really moved it that much ( maybe 10 times in the space of 5 months and this is also becoming a concern. I contacted Apple today and they told me I have 1 year of telephone support and 3 years parts and labour as I order though Higher Education.
They told me that I can go to a Apple store or authorized repair centre to have it looked at, but all the stores are 2 hours away. I asked about mail-in repairs and he said that could be set up but they would prefer if I went to a store. The question is, should I send it in and hope they take care of my Mac i.e don't scratch or mark it etc. After reading some stories about repairs, I'm a little concerned about it, and don't like anyone to touch my Laptop. Obviously I would prefer a replacement as I have work to do and I don't want to be without my Mac.

When I turn on my 17" iMac I hear a loud clicking noise. The noise repeats every few minutes and finally a folder icon appears with a question mark in it. Could my hard drive be failing?

I was out of town so this description was second hand but the computer has been running a little weird for a while. When I have too many apps open or on a website that has a lot going on...the computer starts revving up until I quit out of everything and let it slow down. I guess while I was gone, this happened but nobody quit out the apps and it eventually turned the screen black. When I tried restarting it sounds like the computer is working but the screen is black so I can't see if it is booting up or not. I took the monitor into the apple store yesterday and it started up right away for them. It's a cinema 23" I think.
