Recently my mac has started making faint clicking noises just like a fan catching against something, it is only faint but loud enough to hear. any suggestions please
While it could be a cooling fan, a noise like that is usually a sign of a dying hard drive. Back up everything immediately. Make immediate backups of any new documents you create after the full backup.

Why is my iMac making a rattling noise?
I've had my iMac for 2 months and it started making a rattling noise that has recently gotten worse.
Could just be normal Hard Drive noise, as per > iMac: Evaluating normal noises

Computer noise-sounds like a fan of sorts, but computer isn't hot
I encountered this problem a while back, but it had stopped occurring until just recently. Almost from the minute I boot up, a whirring sound is heard, and it is loud. It's really bothersome while I try to take notes in a class. It almost sounds like it is trying to read a disc or something; however, no disc is inserted. Where top half of the MacBook meets the half with the keyboard, there seems to be hot air blowing out and is where the sound is most audible. If anyone has any suggestions about how to make this stop, I'd love to hear them. Thanks!
CocoHi, coco. That's the cooling fan in your MacBook, transferring heat from the machine to the air that it's blowing through the machine. It's the reason your MacBook isn't hot. If you made it stop, the MacBook would be hot.
To reduce the buildup of heat that triggers the fan, quit any nonessential processes that are running (Dashboard widgets are particularly famous for wasting zillions of processor cycles) and/or use a less processor-intensive application for your note-taking. -
I have had this imac for one year and 2 mos. recently I hear a swooshing noise like speakers are frying when I power up and again intermittantly which lasts about only a few second and quiets down by itself. I have mt portable DVD drive unplugged, I turn down the volumn on the imac but it makes no difference.
I don't have applecare so I guess I should take it to the local apple store in Santa Monica ffor them to check it out. But it could be that it wont do it when you expect it to happen ???
Is anyone familiar with this sound ?Could it be the hard drive making this noise?
Or could it be the fans? -
When my imac is powered on it sounds like a fan is running. Any suggestions?
When I first bought my 24" iMac (2.4Ghz, white version, not the latest aluminum version), it did exactly the same thing. The fan would be overpowering and sounded like a hairdryer on full blast. As a new Mac user at the time I was pretty surprised!! I even called Apple Support and they told me some special ways to reset the machine (that I don't remember and actually did not work).
To cut a long story short and to hopefully help you out -- I unplugged the power source/cable from the back of the iMac, left it out for about 10 seconds, and then plugged it back in. Rebooted, and everything worked.
I would recommend anyone to try this before anything else. Good luck! -

Hard Drive is making a loud noise on my laptop! Help!
Hello,
I have owned my hp envy 17 laptop for almost 2 years now. Recently my computer has been making a really loud noise and it seems it is working a lot harder than it needs to be. I suspect the fan or the hard drive is the culprit but I have convinced myself it is the hard drive.
When I start up my computer the loud noise begins almost immediately after startup. This noise sounds like the computer is working as hard as it possibly can, almost making a grinding noise. Even after the computer has booted up, this noise continues for another minute or two before it stops, then my laptop becomes quiet. What puzzles me, and leads me to believe it is the hard drive, is the fact my computer get unreasonably hot when the noise occurs; it never used to do this before.
This is not what confuses and annoys me the most, it is the sound reoccurring again. This situation is something I have never heard of before. My laptop for some reason ,when it is moved or bumped, even the slightest, start to "rev" and the hard drive roars; it does this for five minutes or so. It also does this when the laptop is closed, and in "sleep mode"; the slightest bump lets it off like a baby. I suspect that there is a switch, flap or wire that is not attached properly and when moved it triggers the hard drive.
I have found a few small solutions to this problem. The main thing I do when the sound occurs is I close the laptop lid which puts it in sleep mode and turns off the hard drive, silencing it for the time being. This solution I came across by accident; I turned my laptop sideways when the sound occurs and the sound stops until I put the laptop upright again(Laptop is open).
I would like to hear your thoughts on this, a solution you might of have encountered or any explanation of the cause; also explain any costs. I have partially opened up my laptop and it looks in order to me with the dust at a minimum. I'd rather check online for a solution first before bringing it to a computer repair shop which, i'm willing to do as a last resort.
Sincerely,
Greg
This question was solved.
View Solution.Without hearing the sound it is hard to judge but it does not sound like a hard drive from your description. Hard drive noise is usually a rhythmic "click" not a sustained "whirr". That kind of noise comes from a cooling fan. We can test the hard drive in the BIOS. Tap F2 as you power up to enter UEFI diagnostics and look for the hard drive test. If you do not have UEFI diagnostics (i.e. your laptop came with Windows 7 not Windows 8) then tap F10 and look for a hard drive diagnostic in the old-school BIOS interface.
The Envy 17 series tends to run hot and cooling fan issues are not uncommon. Sometimes it can be fixed by self-help such as blowing out the fan with compressed air. If it is the fan, the replacement fan is not too expensive but labor might run $80-150 for replacing the fan. Post back with any questions.
If you are going to post back please give us your full model number found on the bottom of the laptop or in the battery bay. -
why my macbook pro making lot of noise inside. Is it something to do my shutting down. I usually shut down my system in every week.
Can anybody provide any solution on this.What kind of noise and when? There are fans inside that run at various noise levels keeping things at the right temperature. There is a hard drive, unless you have SSD, that can make noise when the stepping motor moves the track arm. There is an optical drive that makes noise at startup.
There are noises when you move the MBP and the motion sensor engages. -

Anyone experience an issue with their DVR where it is making a loud noise. Reminds me of the noise a PC makes when the power supply is ready to go...thoughts?
Thoughts? It obviously has to be replaced. You haven't stated the model number, but if you search these pages you will find many posts with the exact same problem you have described (for a given model DVR). It's either the fan (in some models) or the hard drive, because there are no other moving parts.
These devices cannot be repaired in any reasonable way in your home, and the only solution is replacement. Either contact Verizon, or use one of the FiOS stores for a replacement unit. -
SuperDrive vibrating and making very loud noise
Whenever I finish ripping a CD, the SuperDrive starts vibrating (excessively?) and making a loud noise for about 10-15 seconds... I was thinking that was normal, but recently the noise has kept getting louder and this last time the whole MBP was vibrating so much I ejected it before the noise stopped...
Would this call for a visit to the Genius Bar?Yes, a few months ago I noticed it making a lot of noise for 10-15 seconds after CDs finished ripping to iTunes, though I can't say for sure it wasn't doing that before. Within the last few days it's gotten so bad that the whole desk that the MBP is sitting is vibrating heavily... not normal, I assume. :/
This would be under warranty, right? (13" refurb MBP bought in Jan 2010)

Hi,
The fan on my laptop is making very loud noises, like something's stuck in it, but after I took the entire laptop apart, and cleaned the dusty fan, the noise level is still the same (+3 extra screws now...=( ). Is there anything else I can do, or do I need to replace the fan? If yes, can I get a replacement fan at any normal computer store? The model is Compaq Presario V3233AU.
Thanks!
Message Edited by ArielSY on 10-26-2009 09:36 AMSo I just talked to an HP online specialist, and it turns out that it might not be the fan at all, and might instead be the hard drive making the grinding noises. I cleaned the fan, and my laptop temp has gone down significantly, so I'm not sure that was the problem either. The specialist said that I could take the laptop apart, take out the hard drive, and run the laptop to see if the noises continue to confirm if the fan is making the noises. If not, the hard drive is probably replaceable =P
However, he ALSO told me that I could continue using my laptop, regardless of the noises, which was confusing, as I assumed that anything wrong with the hard drive probably had to be fixed immediately for me to avoid losing all my data? Help! What should I do?! -

I just took in my macbook to the apple store to clean the fan because it was starting make a little noise but instead of making it stop it sounds like an airplane about to take off all the time, it doesn't matter what i'm doing. I dont know what to do now? any ideas on how to make it stop?
take it back asap. If it wasn't doing it before they cleaned the fans, they may have accidentally done something that is causing this behavior.
