Computer noisy

  I have just upgraded to a 915pgneo2.My processor is P4 3.6GHz socket775 in a desktop case when i start up cpu temp is 34c, sys temp is 27c and cpu fan speed 2083 rpm after about 10 minutes can be less, cpu temp is about 43c, sys temp is  39c and cpu fan speed is 4560 rpm, does this sound normal because when i start i have a what i would call quiet computer running sounding like anyother to a very noisy running computer with a lot of vibration,is this normal or can this be fixed,i am about to buy a new heatsink and fan but like i said computer runs quietly when first started surely it should stay the same volume anytime, i know cpu warms up but if i put wings on fan it would take off ....any help and suggestions considered

If you're worried about the weight of the Zalman, go with Thermalright's XP-90, http://www.thermalright.com/a_page/main_product_xp90.htm , and couple it with a thermaltake SilentCat I fan.
Here they are on NewEgg if you're in the USA.
XP-90: http://www.newegg.com/app/ViewProductDesc.asp?description=35-109-119&depa=0
Silent Cat I 90mm Fan: http://www.newegg.com/app/ViewProductDesc.asp?description=11-999-136&depa=0
www.svc.com has the HS cheaper, but it took a week to get to me as they sent it UPS ground from the west coast and I live on the east coast.
They also have a 90mm version of the Panflo fan that Thermalright recommends.

  • Why do the fans on my macbook pro suddenly rev up

    The fans on my macbook pro (about 3 - 4) yrs old suddenly rev up and the computer gets very hot. This is sometimes (but not necessarily) at times of optimum use.
    The case seems to be vented ok. I am running Mavericks osx and use computer for range of uses - graphics, e-mails, word and spreadsheets.
    Is this a problem?
    it sure make the computer noisy.

    Hello kiwiwoodz,
    Thanks for the question. After reviewing your post, it sounds like the fan is running at high speed while properly ventilated. I would recommend that you read this article, it may be able to help you isolate or resolve the issue.

  • U3 heatsink sensor went dead

    Hi, I got a dead sensor on my good old PM G5.
    I've noticed few months ago that for no reason one fan go wild and make the computer noisy.
    After checking temperatures, I've noticed the memory board was hotter than usual.
    I got 5Gb there and all are tested okay by Rember.
    As I got programs working only on PPC, I was wondering if there is a way to replace the sensor or how much it will cost to change the motherboard.
    If someone had any idea...

    Hi , and welcome to the forums!
    Unfortunately I sometimes see G5 Logic Boards going for more than whole G5s on eBay.

  • Computer really noisy (fan I think?). Resetting PRAM and SMC does not work.

    Hi,
    so basically, as the title says, my computer is making a really loud noise as soon as I turn it on, I am presuming it is the fan.
    Over a month ago, my computer started to constantly crash, and about two weeks ago I took it to a Genius Bar for a diagnosis. The problem was a hard drive failure, so I had it replaced and yesterday I brought it back home.
    However, after the fix, the computer now runs fine, but there is a really loud noise from the computer.
    I have tried resetting the PRAM and SMC like some other threads have suggested, and none of them have worked. I have tried restarting, shutting down the computer and everything suggested.
    The computer has never made this noise in this manner before.
    Before the fix, the only time it would be noisy like this is when I wake it from sleep, just left it there (on screen requiring username and password) and it sleeps again, and if I wake it from sleep, then it would be loud like this, but that is solved by just simply sleeping the computer again and waking it, and it will be all quiet again.
    However, now, it makes this loud noise as soon as I turn the computer on, and as long as the computer is not shut down or asleep, it will make this noise.
    Before the fix, my OS was 10.4.11, but the Genius Bar had installed 10.5.8 on this hard drive.
    Is this a software problem or a hardware one?
    Anyone got any suggestions or ideas how to fix this?
    I have called the Apple store I visited for this fix already, they push me over to AppleCare and AppleCare pushes me back to Apple store and they tell me they cannot provide technical support over the phone and would need me to take the computer back to the Genius Bar.
    I am just not happy about this. I live almost an hour away from the closest store and I have university to attend to as well.
    So I am hoping this problem can be resolved without having to go back to the Genius Bar, although all methods I have read so far do not help.
    Thanks,

    Hi, well, the thing is, I am just worried that, while making other repairs, they might have damaged something unintentionally and probably do not know about it, which would not be documented.
    My initial problem of a loud fan, after a hard drive replacement, was fixed, so I do not hear it anymore, but this wind-like noise is different. With the iMacs, I presume the fans are towards the top, which was where the loud fan noise came from, however, this wind-like noise seems to come from the bottom of the computer screen are, centre and right side (in the direction I face it), but not the left side.
    I describe it as wind-like, but it sounds a bit like when the computer is on heavy demand and the computer loads, yet different as it is quieter and slightly different in pattern, and unlike the usual heavy demand noise which comes from the top, it comes from the bottom.
    I actually installed a temperature widget after my last repair, just in case my fan was just simply tuned off and would not come on at all for the sake of fixing the loud noise it was making.
    The temperatures read as follows:
    HD: 31
    CPU: 27
    Ambient: 17
    GPU: 36
    GPU Diode: 46
    GPU Heatsink: 36
    HD Bay: 33
    Optical Drive: 30
    To my knowledge, these should be fine temperatures?
    But the noise persists regardless. The noise can instantly be heard (providing that it is quiet enough) as soon as the computer starts up.
    Thanks,
    From Lelouch

  • Scratchy noise coming from top end of keyboard. Not effecting performance but very noisy and worrying! What is it? Is my computer seriously damaged? Is it easily fixed? Thanks for any help

    Scratchy noise coming from top end of keyboard. Not effecting performance but very noisy and worrying! What is it? Is my computer seriously damaged? Is it easily fixed? Thanks for any help

    It would be helpful if you were to identify the model of MBP you have. 
    The noise makers on a MBP are the fan(s), the HDD and the optical drive.  Can you locate the exact position where the noise is coming from?
    Ciao.

  • My computer's fan is so noisy. Should I replace my fan for a new one??

    Hi everyone,
    I bought my Gaming series AIO PC for about one and a half year. I love it's big screen and slim size. I always use it playing online games or watch some movies. But recently, when I use my computer, I heard a loud noise behind my computer. No matter how many time I restart my computer, the noise just won't disappear. :nooo:Is it too much dust traffic in my computer's fan?? How could I clean it?? Please give me answers. I will be really grateful for all the answers . 

    Hi,
    MSI AIO PC has smart fan function and it has different fan speed for different CPU temperature.
    Example: 
     The fan speed will be highest during full loading.
     The fan speed will be higher during helf-loading.
    So this symptom should be normally.
    Thanks.

  • New Imac really noisy after change to SSD

    I have TWO Imac's in my room : an Imac 24 inch I bought a few years old and I have a brand new Imac 27 inch a few months old.
    A technician working for a well know, huge computer retail chain replaced in both IMAC's the HD by 128 GB SSD (in 24 inch Imac) and a 256 GB SSD (in 27 inch Imac). He also added extra RAM : I now got 8 GB in the 24 inch Imac and 12 Gb RAM in the 27 inch Imac
    The 24 inch Imac operates very silent, very quick and very smooth whereas the much bigger and more powerful, new 27 inch Imac now makes A LOT OF NOISE. I am not a sensitive or paranoia person freaky about some computer noise. This is really nervewrecking and constant buzzz. The moment the newest Imac is switched on, the cooler just goes buzzing really loud. This noise has nothing to do with SSD or increase of RAM since they have no moving parts. And the noise is constant. I do NOT use software that requires lots of processing power. I just surf normal websites and do word processing and look at fotos. I don't even look much to video so it's really strange. Where does this noise all of a sudden comes from ?
    The 27 inc Imac was silent when I bought it with HD disk, but once the big HD disk gone, the cooler keeps on blazing and buzzing. Awful ! The guys in the computer shop have no idea, the guys from the Apple official reseller shrug shoulders and say it is "normal" without any more explanation.
    Could it be that by taking the rather big HD out of the inner frame, that the extra space becoming empty lead to an increase of airflow from the fan/cooler circulating freely in the inner frame and thus generating much noise level ???? Anyway, the noise level is totally unacceptable. SSD is supposed to be absolutely silent but now i paid good money for nothing and am stuck with a very expensive but very noisy imac with a nice 27 inch screen but Imac that works on everyone's nerves in the room and adjacent rooms.
    Even guests in the adjacent living room ask what device is generating this constant buzzzzzing.

    Hello,
    Likely the 27" iMac had the special Seagate drive with internal temp sensor & the special Apple Rom to handle the fans, unlike the earlier one that had an external sonsor.
    Since the late 2009 iMacs came out, replacing the hard drive has caused the internal Hard Drive Fan to start running at around 6000RPM.
    This is due to Apple replacing the external Hard Drive temperature sensor with a proprietary firmware and using the drives internal sensor.
Replacement drives do not contain the firmware to deliver temperature data on the temperature sensor cable.
When the iMac does not receive a good signal from the hard drive it puts the fan at full speed to protect the drive.
    If you replace your drive, your iMac will initially seem fine, but soon the fan will begin to speed up to full speed. Resetting the SMC (System Management Controller) will have a temporary effect, but again the fan will speed up.
    Fixes people have used in the past included:
        •    Using smcFanControl and the terminal to set a MAX speed for the fan and writing scripts to start this after every sleep/restart.
        •    Shorting the temperature sensor cable (Not a possibility on 2011 iMacs) this tricks the iMac into thinking the drives temperature is very low, hence slow fan speed.
    Both these fixes are less then perfect and leave the drive in a dangerous situation with no protection from overheating.
    Another option people try is other Fan Control software. These programs will not work for this particular issue as they often only control the base speed, and if they do control the fans actual speed they rely on the temperature reported by the sensor which is now incorrect.
    HDD Fan Control
    HDD Fan Control works to fix this issue by reading the drives internal temperature using the S.M.A.R.T protocol and set the fans actual speed to a value good to protect the drive. 
It runs at startup and continually to always control the fan correctly, prevent the loud fan noise and protect the drive from overheating.
    Instead of HDDFan Control, get the free SSDFan Control

  • Noisy power supply when running of UPS?... follow up post.

    Ned/The hatter your input here would be most appreciated along with anyone else using a UPS with your mac pro. Please read on...
    Having just concluded a rather detailed any lengthy post over in the power mac g5 forum with regards to loud buzzing noise from the power supply running of battery backup.
    I recemmend reviewing the link below for the full and i think interesting read...
    Linked here: http://discussions.apple.com/thread.jspa?threadID=665537&tstart=0
    To sum it up it concluded that my model of UPS (Belkin) produces a simulated sine wave. I am unsure of technicals here, but this then makes the power supply in powermac G5's make a nasty electrical noise as the unit works to sort it out. What is ideal is a pure sine wave i understand.
    The reason for my post was that i was concerned the noise was a sign of harm being done to my mac. No one has said either way yet that this noise is either just a nuisance and it something thats got to be lived or that its actually harming my machine.
    Anyhow it turns out that the RS series from APC also makes the G5 powermac make a noise. And i am aware that Ned along with some others use the APC RS series with there mac pro's. What i am looking to find out is... Do you have a noise from your power supplys when running on battery backup with your new shiney mac pro's?
    The APC smart ups series however does not make the powermac G5 make a noise this has been confirmed by several users. I guess this is because these models produce pure wave sine.
    As you can see this has all got very complicated and over my head.
    The reason for me coming into this forum and asking about noisy power supplys when using certain UPS is because shortly i will be switching to a Mac pro. And if the power supplys in these are different and dont make a noise when running under battery with certain APC Rs's and the new Dual form belkin units then i wont return my current belkin model in exchange for a APC smart ups. I will just live it for a short time whilst i own my G5 and just hope it wont do any damage if and when we have a power outage.
    Thank you to anyone that can guide or assist me with this dilemma. Cheers Pob

    Pobster,
    Switching power supplies (such as those used in computers) do not require a "pure" analog sine wave input; they are more than capable of running on PWM/stepped sine wave input. The noise from the power supply when running on power from a PWM output UPS does not indicate that damage is being done to your machine; it's a harmless side effect.
    Some equipment will be damaged if powered via PWM input; items with compressors (refrigerators, air conditioners) definitely fall into this category, as well as some medical equipment and telecom equipment.
    I live in an area with notoriously dirty power; a UPS is critical in my case (I'd argue that it is critical in any case, however). I've ran my equipment on UPSs for many years, and the price has dropped significantly. I've got one APC SmartUPS with pure sine wave output which was purchased for me by a client, but most of my equipment is running on UPS with PWM output. It's not uncommon for me to have 20-30 power events in a given day - most of them transient voltage drops or spikes; I've still got an old Sun Sparc 10 file server that's still chugging along.
    A couple of interesting articles for your perusal:
    http://www.macosxhints.com/article.php?story=20051009043816537
    http://en.wikipedia.org/wiki/Pulse-width_modulation
    A quick google will turn up lots more information on the topic. APC used to have a white paper on their site which talked about this very topic.
    Most manufacturers provide connected equipment insurance - tripp lite, for example, provides $250,000(US) coverage. I've never known anyone who actually needed to use this coverage - I certainly haven't .
    In brief: A UPS with PWM output will not harm your computer; switching power supplies are more than capable of handling this. If the noise bothers you, look for a UPS with "pure sine wave" output - you will pay more for this feature; it's an aesthetic choice in this case.

  • Is my computer totally dead?

    I've got a 15" Macbook Pro that I purchased in August 2007. I don't remember any more exact specs on it but I'm pretty sure it was the 'middle' model if that helps any. Yesterday, about an hour after I installed some software updates for it, the screen turned into this sort of noisy bright pink grid and it stopped responding. I had audio going and that went on for about 2 more seconds before it started to repeat the same half second or so of audio over and over, like a cd skipping.
    I forced it to shut down and then immediately restarted it, and the screen was still messed up (with kind of pixelated blurs) but I could at least see the normal startup screen underneath. I had been hoping that the restart would fix it completely so when it still looked like that I shut it down again, without waiting for it to totally finish restarting, and I figured I would leave it alone overnight, let it cool off, and so on.
    This morning I turned it on and it really won't even start... I get a screen with a sort of noisy black and white wide vertical stripe pattern. I tried restarting it a few times, taking the battery out, hooking it to an external monitor, trying to run the utility disc... nothing. Now it doesn't even seem to get past the initial start-up phase.... the noise that the cd drive normally makes a few seconds after starting it up keeps repeating it self every 10 seconds or so and the screen always shows the black and white pattern. The external monitor is just blank when it's hooked up. I tried to boot from the utility cd but the computer just ejected it after about 20 seconds.
    I heard there were some problems with, and a program to replace, faulty nvidia graphics cards, but I looked a the page of symptoms and it doesn't seem to match what's happening with my computer. I don't even know which graphics card it has, seeing as I can't turn it on.
    I've never had any problems with it whatsoever before this point. It did happen an hour after I installed a batch of software updates (I know there were 4 items, one was a printer driver upgrade and one must have been the OSX update that adds the app store icon to the dock) which makes me a bit suspicious... whether there was something faulty about those updates or whether it was just a coincidence that this happened afterward.
    What do you think is wrong with it? Something fixable? (I hope... I don't particularly want to buy a new computer at the moment). Would it be possibly to at least salvage the information on the hard drive, if nothing else?

    Hi m, and welcome to Apple Discussions.
    Depending on exactly which model you have, it may be covered under the NVIDIA repair program. I would definitely bring it to an Apple Store or AASP and have it tested. You may be eligible for a free repair.
    If you want to know which model you have before getting it tested, take the battery out, get the serial number inside the battery bay, and enter it here: http://support.apple.com/specs/#
    To get your data, try FireWire Target Disk Mode. If that doesn't work, you'll need to remove the HD, put in in an external enclosure, and access if from another Mac.

  • Should I upgrade my X61 or buy a new computer?

    Hello All,
    This is my first post to this forum primarily because my X61 has been such a workhorse that I haven't needed help until now.  I love my X61--it's small, powerful, and does what I want it to do.  However, read on...
    My X61 is 2 yrs old. I have completely outgrown the 100G harddrive. I also think I'm having a cooling fan issue--the fan is very noisy (sounds like it's going to come out of the case and take off into the 'verse.)  Sometimes when the noise gets very bad, the computer automatically shuts off; I presume this is because the fan is not adequately cooling the unit.  Also, when I first bought the machine, I cloned an XP machine onto this machine because many of the instrumentation software packages that I used for work required XP.  Until recently, the system functioned wonderfully but, now, I think Windows XP might be becoming unstable. Besides, Windows 7 is here now, since I no longer use most of the software that required XP, it might be time to upgrade Windows.
    My question to all of you  more experienced computer people is:  Is the repair of these issues with the X61(upgrading the harddrive and repairing the fan; possibly upgrading to Windows 7) economically rational? 
    First, I will have to pay someone to do the work because I have no idea how to do this myself. 
    Second, there will be the costs of parts. 
    Third, I can purchase a 14" Sony Vaio with 500G harddrive, NVidia graphics, 4G system memory, etc for around $800; although I suspect that doesn't include an extended warranty or damage coverage--so let's say the new machine would cost $1000. 
    I suspect that repairing the X61 will cost at least half of that price.  However, there are reasons to keep the X61--it's been a gem of a machine and it's smaller than the Sony.
    I feel that I'm lacking the insight needed to make an intelligent decision.
    I would really appreciate any feedback/insight/advice that you might be able to give me.
    Thanks.

    Hi landonphd,
    Welcome to the Lenovo forum!
    Pro keeping X61
    It will run Windows 7 just fine.
    Larger hard drives are cheap (~$60) and easy (for a techie) to install.
    The loud fan and occasional shutdowns may simply indicate that your ThinkPad's insides (particularly the heatsink that cools the processor) are clogged with dust. It's easy (for a techie) for open up the X61 and clean out the dust. If that doesn't fix the trouble, replacing the fan isn't that expensive, either. (Guessing ~$50.)
    You love it.
    Pro new laptop
    Windows 7 is much cheaper when bundled with a new laptop, plus it's pre-installed.
    New laptop comes with larger hard drive, as you point out.
    Insides of new laptop will be squeaky clean, free of dust.
    New laptop will be covered by warranty.
    I belive either option could work out fine for you. Given your disinclination to work on the machine yourself, the easier path is probably to just get a new laptop. That option probably won't cost you all that much more, either: your X61 is still quite a desirable machine, you could sell it for a reasonable amount to recoup some of your costs.
    Given your positive experience with the X61, have you considered Lenovo's newest X series, the X200, X200s, and X200 tablet?
    Best regards,
    Frank

  • Hard drive is noisy

    hello, i have an hp elitebook 8570w, running on windows 7 64 bit. it is fairly new (around 4 months old). it has been extremely noisy in the past few days (4 or so), and i am pretty sure the noise is coming from the hard drive. the noise begins as soon as i boot up my computer so it doesnt have to do with it heating up. before that the computer would heat up often because i sometimes put it on my bed, which i know is not the best place to put it. after the noise started i bought a cooling board so now the computer never gets hot at all. the noise is coming from the left side under the laptop. and it is a constant huming or grinding like sound (pretty supid description, but i dont know how to explain it), it is fairly loud and it´s been driving me crazy. also no clicking or anything. i believe it comes from the hard drive, but i am not an expert so i cant be sure. my hard drive model is "hitachi hts727550a9e364". i tried to defrag it, but it was 0% fragmented, since the computer is fairly new. i also have an antivirus, and i did a full scan and the computer was not infected. it hasn't caused any apparent performance issues. please help me, this sound is driving me crazy, i cant concentrate and do my work because of it.

    The type of sound you describe sounds way more like the cooling fan than the hard drive. Hard drive noise is not constant...it is usually clicky like a playing card in the spokes of a bicycle ridden fairly slowly and stopping and starting as the hard drive is accessed. There is a built in hard drive checker in the BIOS...hit F10 as you boot up and loo for the hard drive test in the menus. Run the full length one and see if you get errors.  

  • Very noisy Macbook--what should I do?

    I bought my MacBook (2.2 GHz, 1GB RAM) in mid-december 2007, so it's still under warranty.
    It was all nice and silent at first, but over the last few days, it has gotten really noisy, and it isn't that sound like a jet engine which I know is just the fan working a little faster and nothing to worry about. This one is a sort of steady buzzing sound, which doesn't seem to be related to how much or how little I'm making it do--not hugely loud, but definitely noticeable, enough to get distracting. Sometimes it can be quieter, but it's completely random. It's a bit like the buzz that comes from those fluorescent lights in schools and stores and such.
    I have tried taking it to both the Apple reseller/apple service center I got it from (where I live you can't get apple stuff directly from the Apple representative, you have to visit a reseller, so I used the one the apple rep recommended), and to the 'Apple demo Center' which is basically the nearest you get here to the Apple Stores in the US and elsewhere: they show you the stuff and help with troubleshooting, but don't sell or repair.
    Embarrassingly enough, the MacBook behaved on both occasions, with the buzz being super-low to non-existent, so even though I could describe the noise, they couldn't hear it so they told me its likely nothing to worry about. but I'm still worried, because it is still doing this. So now I don't know what I should do: should I make an appointment with the repair people and have them check it over, bearing in mind I will probably not be able to speak to them directly, but will have to leave a description of the problem, which will be taken down by the person at the reception and then transmitted to the repair guy, thus increasing the possibility for overall confusion, should I go there and insist on showing the repair guy myself so I at least know he heard what I had to say (sorta cut out the middleman), should I go back to the Apple Demo Center which is at least somewhat easier to get to and ask them to look at it more carefully? Should I just put up and shut up?
    Any input from experienced Mac folks out there would be great. at this stage, all I can think of is the time not four months ago when I had to go through all these dilemmas and decisions regarding my Windows laptop, when I was made to go back and forth to the repair place mainly because the customers weren't allowed to interact with the lab folks, and the receptionists kept missing stuff. That experience was one of the main things that made me take the plunge and get a Mac this time, and I gotta admit I am rather near despair at the mere thought of having to go through this again *rueful smile*.
    And yes, if you think I am trying to get you to feel sorry for me...I am But I am feeling pretty low--I was just getting comfortable enough on this machine to start doing interesting things on it, and now this!

    Does this occur when you plug your computer to the MagSafe? If so, it's a known thing, the MagSafe makes a buzz noise.

  • Why is the fan of my Macbook Air suddenly so noisy?

    It has become very noisy. The fan is running constantly. I never heard the fan before. Has something broken. The performance has not changed but it takes much more to start up and shut down.

    Hi aschicchi,
    Welcome to the Support Communities!
    Here are a few troubleshooting steps to address your fan issue:
    Intel-based Macs: Resetting the System Management Controller (SMC)
    http://support.apple.com/kb/HT3964
    "...these symptoms may indicate that an SMC reset may be necessary:
    Fans
    The computer's fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated."
    Before Resetting the SMC
    Try each of the following steps in this order before you reset the SMC.  Test the issue after completing each troubleshooting step to determine if the issue still occurs.
    Press Command + Option + Escape to force quit any application that is not responding.
    Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosingSleep. Wake the computer after it has gone to sleep.
    Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
    Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
    Resetting the System Management Controller (SMC)
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer. 
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
    I hope this information helps ....
    Have a great day!

  • Audio ok on computer, bad on stereo

    I downloaded songs off itunes to go with my slideshow. I created it in iphoto then exported to idvd to burn. On the computer, the songs sound fine, but some of the songs do not sound good when i played it on my dvd/tv (sound coming from stereo). How can sound quality be fixed to sound better when not played on computer?

    but some of the songs do not sound good when i played it on my dvd/tv (sound coming from stereo)
    What does "do not sound good" mean? Scratchy, noisy, poor low freqs, poor high freqs?
