Fan noise like a hair dryer at full blast

Hi there,
I have had this IMac G5 (1.8G) since beginning of 2005, every time I go to a web site which has flash - my IMac fan goes on very loud noise like a hair dryer at full blast.
Does anyone know what the problem is? and how do i fix it?
Thank you for your help,

How much RAM do you have? Did you check the Apple extended warranty that I mentio0ned in the other thread?

When your Lenovo Twist makes a noise like a hair dryer -

I apologize for my English, but I have something to say.
Trying to finish my PhD thesis, I decided to buy one of the last Lenovo creations, the ThinkPad Twist.
Bought the last February, the fan noise becomes more and more like a hair dryer that never stop; I can’t work more than one hour because the noise is hardly resistible. I took the laptop to the library and the noise stop the calm of the place…
After this incident I tried to contact the support center to have one solution. This is my history:
First call to Lenovo support center, I explain the situation, a fan that never stop and sound like a hair dryer…. Answer: They propose me send the computer to the repair center: “tomorrow UPS will take the computer”. Just here fine, but I didn't’t receive the e-mail confirmation.
Second call, I give the number that they told me to write over the box for UPS , and I ask for the confirmation mail… they send me the confirmation mail and finally the Lenovo Support Center guy told me that UPS wouldn't’t go to my home to take the computer, according with my warranty, it’s my responsibility to the send the computer to the support center…
-So I decided to change my warranty to have the “On site/In-Home Service”, that means “a technician will be dispatched to arrive onsite, typically the next business day. *** Onsite service is available in metropolitan areas only”, and I live in Paris. -
Upgrade warranty bought May 02, 2013 (Thursday) and activated the next day (Friday). I decided to call the support center to update my request. The answer: "One technician will go to your home the next business day (Monday)", so I give all the details to arrive to my home, I change my schedule to be at home all the Monday and finally the technician never came… Only one guy of UPS to that one box. o.O
Next call to support center (LSC), I explain the situation “I wait for a technician who never came…”. Explanation from the support center: “Lenovo France have to forward one request to confirm my new warranty” but…. I explain: The warranty was activated in the website, in my computer and I received a lot of confirmation mails… So I ask, what I have to do? – Answer: wait….
Next day, next call to LSC, I ask for the situation of my request… Answer“Lenovo France have to forward one request to confirm my new warranty” but…. I explain: The warranty was activated in the website, in my computer and I received a lot of confirmation mails… So I ask, what I have to do? – Answer: wait….
7,8 cents for each call and 2,8 cents by minute of communication is the introduction phrase of the LSC number.
Today I called to LSC, May 10, 2013 (Friday), ONE WEEK after the upgrade warranty activation I ask for the situation of my request… Answer “Lenovo France have to forward one request to confirm my new warranty”but... I explain: The warranty was activated in the website, in my computer and I received a lot of confirmation mails… So I ask, what I have to do? – Answer: wait…. We will call you…
I am very disappointed. I was thinking that I had the most powerful computer in the market, one of the best Lenovo that all my coworkers talk. I am really unhappy, my new computer sound like an expensive hair dryer (1000 € - yes, euros) and the people that should help only tells me to wait - “we will call you when validate in France your warranty” - but…. The warranty is activated.
If my computer makes a noise like a hair dryer at least you have to know, do not you think?

Hi Emilio, welcome to the forums,
sorry to read about your experience so far and would like to share some points which you might like to consider based on my personal experience as an IBM / Lenovo reseller.
In most of Europe the standard warranty conditions are for so called "carry-in" or "bring-in", this means that the customer is responsible for transporting their system to the service depot / partner, by post or other means.
Also it can take a little while, sometimes three weeks, for an on-site warranty extension / service pack to be fully activated when purchased some time after the system itself, even in the IBM days, and would not cover a call which had already been opened / started.
As your system is working, although the fan seems to be permanently running, you may need a little more patience and let's wait and see if they will cover your already opened call as an on-site.
I know this isn't maybe what you wanted to read, but is based on my experience, and as experiences will differ I can only hope that the right solution arrives for you a little quicker than I personally would expect.

DOES ANYONE HAS A PROBLEM WITH A FAN NOISE LIKE A METAL BEARING

I want to know if there is a problem with some of you that have a 20 inch early Imac I got this imac last june and now I begin to hear a hizzing noise like if it was a fan bearing or something.

The drive is in the area where the vent grill is above the plug. There is a very low level disk "activation" noise (sort of a faint ticking type of sound) whilst it is working but then stops, where as the fans again very low noise can be heard all of the time - just. I sit about 650 to 700mm from the machine.
The drive is only a manmade item and occasionally one will start to fail early in life. Today is unlike the old days where a vari-speed floppy drive could need changing every month if worked in a commercial environment and a hard drive wasn't much better.

1 month old macbook sounds like a hair blower while playing movies

Today for the first time I played a movie on my mac and it sounded like a hair dryer/blower during that time, is it normal?
Is there any option to reduce the fan noise?
Any tips or advice will be highly appreciated. Thanks.

It's normal.
The fans are cooling down the spinning DVD drive and the computer showing the movie.
If you load a YouTube movie, it'll probably do the same.

Fan Noise? Is this normal?

http://dl.dropbox.com/u/9081819/Default%20System%20Input%2020101204%201346.mp3

Whether it's normal or not depends entirely on what the computer is doing, how hot it is, and how fast the fan(s) was/were spinning when you made the recording. That sounds like normal high-speed fan operation to me, but we'd need much more information from you to make any really sound comments. Which MBP model do you have? What does iStat Pro report about your fan speed and CPU temp when the fan noise gets loud? What is your fan noise like at the default speed of 2000 RPM?

Imac dvd fan turns on randomly full blast

Hello all, new to the forum; I recently added an iMac 12.1 (mid 2011) to my many computers. I had the common grey blemish problem where I took the LCD apart and cleaned it(not that bad). But I've noticed recently that my DVD fan will randomly turn on and go full blast now for no reason, under little to no use at all. (Using fan controller to tell RPMs). Ive tried the SMC reset a few times, and a PRAM reset 2x. Any suggestions what it could be? I'm out of warrenty, so I'm not paying the apple store a dime to change anything, I have a lenghty IT background; just not on iMacs lol.

In addition, the computer runs perfectly. No lag, no freezing nothing.

IMac from 2009. Suddenly making noise like a loud fan.

My IMac from 2009 is suddenly making noise like a very loud fan, or a little like a vacuum cleaner. The sound seems to becoming from the IMac, not my speakers. Could this be from any of the wires or connections plugged into it? Restarting the computer did not stop this. I think this happened once before a long time ago. Anything I can do?

Before I saw Mike Sombrio's post:
I restarted the IMac without unplugging the power cord, but the noise was still there when the IMac came back on. Then I repeated this about 10 minutes later, (restarting the computer without unplugging the power cord). This time the noise was no longer there. I don't know what's going on. I hope this problem does not return. Any explanations? Is this a sign that my IMac is having serious problems? Any advice?

Sounds like Right Hand side fan noise

I've had my powerbook for over year now. I don't have the AppleCare. Ever so often I will hear a noise coming from the right side of my laptop. It doesn't seem hotter than usual. It doesn't happen all the time, but every now and then. I'm a bit concerned as I don't want my system burning up. Any suggestions of what it can be or how iIcan fix the issue?

The fan (fans) will come on once in awhile if the processor load is high. As long as its not too loud, just normal fan noise, what you are describing may be normal. When the fan runs take a look at the Activity Monitor to see what the processor load is.
A couple thing you could try if you are concerned...
Run Apple Hardware test included on the original OS DVD, Disk one. Insert the disk and reboot holding down the Option key. You will be presented with a menu, select "Apple Hardware Test" and follow the instructions. The long version of the test will test the fans, memory etc. When you insert the disk (before you re-boot) there should be an Apple Test Readme file in the finder.
Also... Download one of the temperature sensor utilities. Here's one:
http://www.bresink.com/osx/TemperatureMonitor.html
This will give you a look at the temperature of the Battery, Power supply, Processor and hard drive. There's also a widget or two on the Apple web site.

MSI GTX560 Ti Hawk - underclocking and lowering temp/fan noise

So the most common feedback about the MSI GTX 560 is that it runs hot and it's noisy.
What happens if i underclock via Afterburner? Surely i don't need it to run the card OC right there's plenty of frames available..... when i underclock i can't seem to notice any difference when i'm playing BC2. My frame rates are still approx 80-over 100+, that's high right?
Is frame rates the key factor in a smooth game play - what reduced frame rate should be be avoiding? Anything else to watch out for?
What else can i adjust in Afterburner to get the card to run cooler and quieter? - i read that i shouldn't reduce the memory speed though.......since that can slow down the processing.......

I'm no expert but I am having temp and noise issues with an MSI 560 card so I'm sharing what i know.
Overclocking is often a kudos thing.
The actual framerate increases are marginal unless you are hovering around the 24fps avg mark then juicing the card a bit can get you above 30fps mark ( a gamers minimum)
I to don't like to hear a hair-dryer in my PC when I game so to get the fans to go slower you need to make the card produce less heat.
Undervolting does not effect framerate , reducing voltage reduces heat but, if pushed to far, will cause games to crash out or artefact meaning you need to add a bit more back in.
Technically you can run the card at 99 degrees and you could could maintain that temperature at a lower fan speed than trying to run the card at 70 degrees.
You could try to find a stable undervolt (a good few hours of gaming with no artefacts of crashed) with every other setting at stock.
To find an acceptable fan profile you can run a game windowed (so you can keep an eye on temps) put lots of AA onthe game just to make sure the gpu is at 100%. See how high the temp goes, you can then find your optimum balance between heat and fan noise.
I personally want my card at about 70 degrees under load (allowing it to touch 80 on a hot day when playing games for hours)

Constant fan noise on macbook pro

Hello, my macbook pro (mid 2010 model, 13 inch, 2.4 ghz intel core duo 2 running Mountain lion) is experiencing constant fan activity at very high speed. The CPU however is only used at 9% of its capabilities top. The problem occured after a freeze in adobe Lightroom, since then, the fan noise start as soon as the computer starts (except if i press some keys before i turn it on for some reason, the noise would come back if i shut down the computer and restart it, or simply close it). I'm dully aware that it is normal that the fan is constantly working, but not usually at such high speed (top speed of the system), I checked all the major solutions offered on the net so far with no success (reset SMC, reset Pram, checked if i had some printer activity on the waiting list, checked the activity monitor for any particular demanding activity or tasks and finally i tried to run an apple harware test to see if some temperature probes are broken on the motherboard, however my computer for some reason is not taken care of...).
I also would like to mentionned that i change the original hard-drive not long ago for a hybrid harddrive (seagate momentus XT), yet the problem did not start after the change.
if you do not think of any solutions, you could maybe tell me if its problematic for my computer's fan to run at full speed..
thank you very much for any help you could provide and sorry for the eventual mistakes in english (its not my first language).

Re: Apple Hardware Test. There was no original install disk, as i downloaded mountain lion. While the connection was established to access to Apple hardware test, the test could not run on my mac, the AHT program said that my machine was not supported.
thank you for your diagnostic, it seemed to be a logical explanation, however, thanks to a monitor program i could check that my processor was running under normal temperatures (35°c to 75°c) so at least the temperature informations seems to be correctly assessed by the sensor.

IMac g5 fan noise with update to 10.4.11

Has anyone else experienced this?
I have never had any problems with fan noise with my iMac, though I know it's a problem, till the recent update to 10.4.11. After restarting, it sounded like an airplane. Never heard that before. I shut it down and restarted, and it doesn't sound like a plane anymore, but the fan is noticeably noisier than ever before, a constant whine/hum.
Besides the energy saver fix and resetting the SMU and canned gas in the vents, any other suggestions? This is annoying, it's been running pretty perfect for three years till this. Thanks.

The questions are certainly not dumb - almost anywhere is cheaper than Apple for RAM, I recommend [macsales.com] and [smalldog.com] or [newegg.com]. I don't think that going back to 10.4.10 will help, you should really vacuum the vents to get dust out, and make sure that there's nothing hogging your CPU and making the fans noisy, look at Applications>Utilities>Activity Monitor to see if anything is using an unusual amount of memory or CPU.
If you do want to install Leopard, I would suggest making a full backup of your system,I use SuperDuper! to clone my system to a firewire external drive. You should certainly upgrade your RAM if you install Leo, but I don't think your machine will be any quieter with a new OS.
You need to remember that your machine is several years old, and that things get creaky with age (I certainly have). Since you have the iSight, it's not a simple matter to open it and clean the fans off. If you are really disturbed by the noise, you can take it in to an Apple service place and have them clean and oil the fans, which should help enormously.
Sorry I couldn't offer more help, but fans will, and do, get noisy.

My new Imac 24", 2.8GHz Intel Core is suddenly making a loud fan noise

Please help!
This Imac is only a week old. I bought it on apple online store. This is 24" 2.8GHz Imac and it's been the best computer I've ever had. It was wonderful to work and silent until yesterday. And suddenly I can't stand the fan noise coming from my new Imac. I downloaded i-stat Pro to check the status of my computer and it reads *CPU fan:1198rpm, hard drive:1198rpm, optical drive: 4401rpm*
what is wrong with my computer?
I searched many mac forums, and I've tried many things including shutting it down and unplugging everything and replugging everything after a while, but nothing solves this problem. Does anybody have experienced this problem? I am not even using many applications. I am only using safari, and the fan is at full speed. SO LOUD! What can I do to solve this? Should I take it to apple to look at it?

Hello lovingimac
Welcome to Apple Discussions
That sounds like there is something wrong with the temp. sensor for the optical drive.
If carefully following the SMC reset instructions below, does not fix the fan issue:

Then yes you need to make a trip to your local Apple service center.

Excessive Fan Noise in Mac Pro (Late 2008)

Starting in October of 2009, at about one year of age, my Mac Pro started cycling through periods of excessive fan noise: the fan goes from quiet/inaudible to so loud that I cannot hear talking on the radio in the room.
Re-set the PRAM.
Re-set the SMC.
Ran HW Test (Full test) and got the following: 4sns/1/40000000:tcbh -127.500
Called Apple Support.
Re-ran Hardware Test showed no problem.
Did nothing more. Machine seemed fine.
In January of 2010, the problem returned.
Ran HW test (Full test) and got the following: 4sns/1/40000000:tcbh -127.500
Per instructions from Apple over the phone, I took the Mac Pro to a "Genius" at the local Apple Store "Genius Bar."
The "Genius" booted the Mac Pro on the store network (while I waited) and got the same error message. The "Genius" said he would order some parts and install them.
Left machine.
Received call one day later from another "Genius." He said the first "Genius" was wrong. They've been running the machine continuously with no error message at all. (BTW, he treated me like an idiot, though he clearly didn't have all the facts in the store's own record about the machine. Typical 20-something IT kid.) After some argument, he agreed to run more tests. Received another call fro yet another "Genius" telling me the machine was OK.
I picked up the machine.
The fans continue their behavior, BUT HW test (full test) now shows NO error.
At rope's end. Clearly Apple will be of no assistance, despite the warranty I paid for.
The machine cannot be used in the same room as I as I cannot talk on the phone, etc., with the fans running so loud, which they appear to do every 30 to 60 minutes.
Any ideas?
Some thoughts:
The problems started not long after installing 10.6. Coincidence?
I am not sure, but I think the fans go nuts whenever I use iTunes or Quicktime. I have not tested this and I could be wrong, but whenever I have those programs closed, the fans seem to settle down.
If no one has any ideas, I'm thinking of selling the machine and getting something else, as it is not useful "as is."

There are reports of the new MacPros having heat issues rendering audio (QuickTime/ iTunes).
Seems to be a hardware configuration issue not a software problem.

No video, high fan noise on startup, for the THIRD TIME

For the third time in slightly less than three years, I have encountered the same crippling problem with my iBook G4 (1 GHz, June 2004 vintage). In essence, the screen will abruptly go black while in use (not screensaver) and no amount of keyboard/mouse activity will reactivate the display. If I power off by holding down the power button then restart, the screen stays black and the fans come on full speed.
Despite a bit of confusion on the details, this sounds like the problem described on the webpages below. In essence the Danish government has issued a finding that there is a design flaw which allows excessive logic board flexing, which in turn causes logic board failure.
This is, as I said above, the third time I have encountered this failure in less than three years. Worse, they seem to be coming closer together. The first was after about 1.5 years, the second 9 months later, and now seven months after the second repair. Since I didn't get Apple Care, paying for a third repair out of pocket would bring my repair bill up to the cost of a new iBook.
I do not abuse my iBook, and since the second repair I have been very careful with my iBook. Does anyone have any suggestions on getting Apple to acknowlege the problem or who I can appeal to? Apple's website doesn't seem to offer any e-mail tech support options and I'd rather not sit on hold for an age (again) if it can be avoided. While I don't want to abandon my iBook or Apple, I may be forced to if I can't rely on the hardware.
Thanks

iBook G4 1GHz (early 2004) Mac OS X (10.3.9) blank screen, high fan noise on start

Well it doesn't sound like the Danish power problem since it will start up.
The ATI Mobility Radeon 9200 4x AGP graphics processor chips in these iBooks have been problematic. Usually it's the reball problem and it can be reballed for ~ $78. I've done 4 this year and they work just great. A cheap way to get nice laptops. If they respond to the "shim fix" then reballing will work.
A more troubling problem is with the 9200 chip itself. My reballer says that this chip is in itself the cause of some of these problems. He knows it since it's also used in IBMs, Compaqs and many other laptops and he's seen a lot of failures. My only failed reball was a 9200. I have a line on a replacement board or finding the chip in a broken PC.

TPfancontrol: Yes or No? How to control fan noise?

Hello,
I am new here, got my t400s 2801-CTO a few weeks ago.
Send it to repair after 2 days: I had issues with a high-pitched electric noise coming out of the speakers?(I think that many of you must have heard of this). Got it back (they replaced the speakers) and it wasn't any better. Until I found somewhere on the community forum that this sound is common to ThinkPads and that if I disable in Bios the CPU automatic power management (in config), it'll be better. YES IT WORKED. I figure that this community is way more helpful than the whole Service Center in Atlanta.
Now I need to take care of FAN SPEED before I turn this machine finally into a QUIET MACHINE.
I've heard that many use PTfancontrol to control the speed and noise of their Thinkpads?
How safe is this for the computer? What settings would be appropriate for T400s? And where to download this software?
Alternatively, what other forms of fan control does Lenovo offer?
i've found some fan control from Lenovo but I am not sure if this would work?
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-73410
Any help will be appreciated.
Christina

Sound like a "catch 22". You turned off CPU power management so it runs at full power all the time, which requires the fan to run full blast all the time to keep it cool.
If you turn power management back on, does the fan slow down when the machine is just idling?
Sorry I don't have a fix, but maybe figuring out the cause(s) will lead to one.
