Help me replace my noisy fans, please!

I've put up with this noise for far too long. It now sounds like I've got a plane landing in the house. I'm sure it's the fans.
I've never attempted things like this before except for fitting airport cards etc. Is it easy?
I read an article about SilenX fans and I believe that these are available in the UK. I have no idea what size to buy.
Any help would be gratfully appreciated (especially by everyone else in the house).
Cheers. John

Glad that it downloaded for you.
As for which fan, that is something that will be empirical. The fans are for cooling. If you could keep the components cool with big heat sinks and natural convection you wouldn't need any fans. There are pc case makers who do just that. Very expensive cases but the only moving parts are the hard drives and optical drives.
So, download Temperature Monitor and read your drive and cpu temps now. It wouldn't hurt to take a reading of the power supply temps (back of case at the top). Use those temperatures as a baseline that you don't want to exceed without good reason. It is also a good idea to take a temperature reading at the front bottom of the case. This is where the air is drawn into the case. This will tell you what temperature difference you are looking at. You can also check to see how the room temperature changes the temp on the cpu. Once you have an idea of how much cooling you are getting right now you can watch what happens with fans that you install.
If I were going to get a very quiet fan I'd opt for the SilenX 120mm faster fan. 30db of noise is not quiet. 25db is pretty quiet. Anything below 20db is silent as far as I am concerned. I have SilenX 60mm fans in my power supply for 2 years now and no problems but I have the revision 2 power supplies (slightly lower power output). I just ordered upgrades for the cpu's to take them to 1.33gz and will probably not go with quieter/hotter fans than the Papst that is in my mac right now. I'm really hoping that the new processors will accept CHUD's nap feature. More than any other change I have made to my mac, this keeps things cool.

Late 2006 Macbook fan noise - How much does it cost to replace a noisy fan?

Hi there,
I have a late 2006 Macbook that has served me well over the last four years or so. Unfortunately, the fan is now making one heck of a racket (almost as soon as you switch the machine on).
I gather this is a relatively common problem with this generation of Macbook and can be fixed by replacing the fan. I'm not proficient enough to do this myself so will likley have to take it to an Apple Store to get it done. I wondered whether anyone else had already done this and if so how much it cost them and how long it took? Any info / tips warmly welcomed.
Thanks,
James

I suggest you do a search for MacBook repairs. There are many shops that will do it cheaper than Apple. Most can give a quote on a known repair online.

Noisy Fans

I have owned my dual G4 since 2002, and its still going strong!!. I want to replace the noisy fans, so I did abit a research and came across an apple web page about apple replacing the fans for $20. The problem I have is that the offer ran out in 2003 anybody got a idea of where I can pick up some fans cheap.

Hi there! Welcome to the forums!
I am glad to hear that your machine is going strong!!! Mine is also.. the MDD's just won't die without a fight given the intel macs of today. However, back to the topic.
What kind of power supply do you have in your MDD? First off, if its the 400 watt power supply, I would suggest trying to find the 360 watt power supplies. Those are the much quieter ones that Apple sent to customers back in 2003 to relieve the noisy ones - also the pabst fan was a replacement as well.
Once you do this.. get then a PCI slot fan to help in cooling the machine down. Next step is to mount(like I did) a 120MM power fan on top of the optical drive roof and have it blow the air out towards the back - this will aid in cooling down your system DRAMATICALLY. My pabst fan is close to silent now, though I can hear it sometimes, but I also have the power to control the fan's speed as well. Sometimes to get rid of dust and foreign particles which could hurt my system, I rev the fans for awhile in HURRICANE mode. I guarentee that your MDD will love the fans. Oh, one more thing.. Put a small 60MM fan underneath the front drive bay. + GET THE COPPER HEATSINK - this will further aid in cooling the system down.
Right now my dualcpu temp is: 90 degrees fahrenheit.

Hi Guys
I need your help on this. My 3 months old iMac (iMac 24inch 2.8GHZ Core 2 Duo Extreme) fans started making so much noise that is unbearable. They came on suddenly (you could see the wave of air) and even though I switched off the iMac for the 24 hours, when I turned it on, they noise is still on. The iMac works fine, but the noise is very very loud. The computer is in well ventilated room, so I dont know what is happening.
I bought it from apple.com and I dont want to go through all the drama of sending it for repair if there is a quick fix.
Thank you for your time.

Replacing noisy fan in MDD Mac

Hi all,
I've read the MDD models were called the wind tunnel machines due to the noisy fan. Has anyone replaced the fan in a MDD to make much quieter? My MDD has been shutting down without warning at times and I was wondering if it can be a fan issue. Thanks, web dude

Hi-
Has anyone replaced the fan in a MDD to make much quieter?
A very common mod. Google will yield many reports like this one below:
http://www.xlr8yourmac.com/systems/g4mirrored_drive_doors/noise_reduction/g4_ddr_noisereduction.html
My MDD has been shutting down without warning at times and I was wondering if it can be a fan issue.
Usually due to overheating of the processors.
Applying new thermal compound to the processor heatsink is a good idea.
Running CHUD tools to allow nap mode is also important for the MDD to run cooler.

Own two T430 notebooks, one has noisy fan, the other has a silent fan

Hello there,
I have owned several ThinkPads over the years and recently purchased two T430 laptops - one for travelling and one for my girlfriend for school. I was aware there has been a fan issue as it has been documented all over the web, but I purchased anyway to see how the dice would land. Well the dice have landed and I have one silent computer and one noisy one. I am not too surprised by this because I have read in forums that some owners do not know what others are complaining about.
I believe this is a hardware problem and not firmware. The BIOS updates will only change the fan speed at given temperatures and are not able to reduce noise at a given fan speed. The quiet T430 is running with the 2.09 BIOS (10/19/2012). The other T430 has been updated twice and is currently running 2.54 BIOS (4/22/2013) and is just as noisy as before. Both T430's have the same fan speed at idle, just one is much noisier.
It is not very common to own two T430's to be able to directly compare noise levels, especially nearly identical configurations, but I do:
#1: T430 with i5-3320M, integrated graphics, 1366x768 LCD, 4GB RAM, 500GB HDD, W7 Pro, Finger Print Reader.
#2: T430 with i5-3320M, integrated graphics, 1600x900 LCD, 4GB RAM, 320GB HDD, W7 Pro.
#1 is noisy, #2 is silent.
I also own a W500, T410, and W530 and have had them all running next to each other at once to compare them. The T430's are the loudest at idle (including the "silent" one) and have the most air flowing through them, but the T410 is close behind. The fan noise is pretty quiet and acceptable for the T430 #2 and the T410. The W500 is extra quiet and the W530 is so silent it requires close inspection to determine if the fan is even on. Anyways, I have two very different performing fans in two nearly identical T430's. BIOS updates do not affect the sound - it must be hardware.
I am going to call technical support and request a new fan assembly for the noisy T430. This post is meant to get the attention of Lenovo and all the unfortunate noisy T430 owners. A quiet T430 does exist and I am going to attempt to make a noisy T430 be quiet. I will update this post through the replacement of the fan to let everyone know how it goes. I have read people have replaced their fans as many times as twice with no improvements - I will inspect the chassis and neighboring components during replacement to see if there is anything causing a good fan to be noisy. I am optimistic that I will be able to fix this.
If you have had success repairing a noisy T430 fan, please share how you repaired it. Otherwise, stay tuned as I attempt the repair and provide updates on my progress. Thank you.

Hello everyone,
I called Lenovo Support after starting the thread and learned that they do not send out parts like fans or motherboards for warranty claims. Instead, I had to sent my computer into Lenovo for repair. It took me a couple weeks to find time to wipe the machine to remove any personal data, but I finally called support and had them send me a box to ship it back to them. The box was overnighted and arrived the next morning. I dropped it off at a local UPS store Monday morning and my computer was shipped back and delivered two days later on Wednesday afternoon. Much faster than 7 business days they quoted.
The T430 was finally unboxed today and I started setting it back up. The fan assembly was replaced and they also replaced the cracked power port. I am happy to report that the dice landed in my favor, and this fan is just as quiet as my other T430.
I am a little disappointed that I wasn't allowed to replace it myself, but I can't really complain... Sending it back to Lenovo to get repaired under warranty fixed my fan within 3 days. There is a chance this might not work for everyone since this seems to be a intermittent hardware issue, potentially from one of many suppliers of the fan, but you can probably keep sending it back to Lenovo until it comes back quiet.
I would like to mention that the little fan noise that my quiet T430's make is a little odd sounding. The first stage fan speed is the one that sounds the most odd (the sound of air rushing out at higher speeds muffle this subtle sound): With my ear 1 inch away from the exhaust of the fan on the left side of the machine, the fan sounds like it is rubbing on something, producing a noise similar to noisy brushes on a DC motor or "white noise." (it is hard to describe). But the really interesting part is when the machine has been idle and the fan kicks off, the rubbing sound suddenly drops off, as if there was a brake on the fan. My W530 and W500 produce a "normal" fan sound that gradually changes as the fan speed changes. This rubbing sound in the T430 is a little concerning and I am not 100% confident that these T430's will stay quiet over time. Luckily I have 3-year warranty on these T430's, so I won't get stuck with a loud fan should they become loud.
I hope this helps some of you out there. I am sorry I wasn't able to look for the root cause of the noise issue (didn't want to void my warranty), but Lenovo will attempt to repair a fan noise issue by replacing the fan assembly and they do it in a timely manner.

Mac 8500 Noisy Fan

The fan in my Mac 8500 is getting progressively noisier. A rattly type sound.
Can it be replaced?
The fan appears to be an integral part of the power supply as near as I can tell. Is the fan a separate item or does the entire power supply need to be replaced?
Where could I find replacement parts?
Thank you.

If you "run the numbers" off the label for the original part, you will often find the specs online. Exact replacements are often available -- in the handy 10,000-pack.
If you want somewhat fewer than 10,000 parts, I suggest you take the specs for airflow and noise generated in hand and look at this site, because it has good variety and can help you converge on exactly what you want -- whether you buy their offerings or go on to search elsewhere:
http://www.buyextras.com/dc12vfans.html
Note: fans with an additional yellow wire are compatible with fans that use only red and black. The yellow wire is an RPM Output from the fan. The Mac does not use it, and it can be safely ignored.

Replacement Power Supply Fan Or Whole She-bang.

A few of you may have seen my posts here recently regarding upgrades. Well, good news is that they are all in and working...fairly well. There are a few hiccups that I will be monitoring in the next week.
Anywho, something that I have determined to be an issue is that the Power Supply Fan is, for a lack of a better term, pulsating. Its running at all times but in a distinct cycle it increases and decreases in volume. One cycle is about 4 seconds I would say. I was chatting with the support people at Sonnet thinking it might be the fans on the Dual 1.8GHz processor I installed, but it wasn't. When I determined it was the power supply fan, he said he had an issue previously and said he installed a replacement fan and its worked fine ever since.
Does anyone know if Apple still offers replacement fans for a Quicksilver 2001? Or where I could buy it elsewhere? I've checked online but only find power supplies.
The power supply brings me to another issue. I have pretty much upgraded this computer to the edge. Its a 340Watt Power Supply (i believe) and I am running 4 internal hard drives, 4PCI cards (two of them are hard drive controllers), a new ATI Radeon 9800 gfx card, and the new processor. All my plugs are in use and I have one of the plugs split off into two plugs for the SATA drives.
I figured the supply was enuff, and the computer is working and doing evertyhing I need it to - well almost, i'm having an issue where Quake 4 crashes itself and the computer from time to time but thats it. But I definitely notice the fan is running louder since upgrading.
Would it be advisable to upgrade the Power Supply? Is that even possible. Online I dont seem many power supplies greater than the one I'm already using.
Thanks in advance to any help posted.

Ok.
I got a wierd problem. I am receiving the grey screen with the folder face icon while intermittenly flashing the "?" that its searching for the system folder.
So, i replaced both Case fan and Power Supply Fan. They are running fine and blowing air well. It turns out that the case fan really was the one that wasn't working well at all. It was dusty. The powersupply fan was dusty and I got rid of all the junk in there. I use the power adapters and they seem to be fine now.
However, after I put everything back together, thats when the problems started.
So, to remind....
I have 2 SATA drives connected to a SATA controller. One of these drives is my start up disk.
I have an 80GB PATA drive in the original drive slot.
I have a 200GB PATA drive connected to a Sonnet Tempo Ultra 133 Hard drive controller.
I plugged all the connections back to their places the way they were before.
Once all the power cables and connectors were in place. I plugged the power cord from the wall socket into the back of the power supply. I pressed start and I got the grey screen immediately, then my 200GB PATA drive began clicking. And then the folder icon showed up. Then the harddrive stopped clicking.
I'm also not able to eject the disc drive.
I force shut the computer down. Unplugged the 200GB drive. Started the computer, and I came to the same grey screen. Still searching for folder. I shut down and unplugged the SATA drives because I still have the old OSX.4.11 system folder on my 80GB drive. Still, grey screen and search folder.
I shut down again and uplugged the 80GB and plugged in the SATA drives. Still searching for folder.
What should I do? I tried booting into Target Disk Mode onto my laptop, but it didn't work.
PLEASE ADVISE!

Noisy fan and laptop heats up

Hi,
I have a problem with my laptop. It's a G60-249CA model. Each time I turn on my laptop, the left part of the laptop starts to get warmer and I can hear the fan noise getting louder. The sound gets even louder when I use a site that uses alot of graphics and the laptop gets warmer and then my laptop will flash a black screen and shut off.
Is there a way to fix the solution ? The warranty does not work anymore. I have thought of taking off the back of the laptop to clean the fan up or to get a new fan and replace the current noisy fan.
Are there any other solutions ? Please advise me.
And also, when I turn my computer on, I have to tilt my screen to a 45 degree angle to see that windows is running.
Is there anything wrong because if I turn my screen to any other angle, all I see is a black screen.
Kindly advise, thank you

Hello Kelli68.
Have you tried updating your BIOS? Here is a link to the latest BIOS.
Also, if you want to try replacing the fan you can get the part number from the manual which Huffer posted above. The parts should be available for purchase on the HP Parts Surfer site.
Have a lovely day.

Need Help in Replacement of Function Modules

Hello all,
I am working on Upgrade project from ECC 5.0 to ECC 6.0. I am facing problems for Replacement of two Obsolete Function Modules. Please give me a solution. FM's are as follows.
1) SET_AUTHORITY : This FM is obsolete in ECC 6.0 and there is not alternative FM present in help.sap.com or any other web portal.
2) WS_QUERY : Here as per my knowledge we use class CL_GUI_FRONTEND_SERVICES and methods FILE_EXIST or DIRECTORY_EXIST as per the parameters in old FM. For parameter 'FS' we use 'FILE_EXIST' and 'DS' we use 'DIRECTORY EXIST'.
But in our program prev. FM has parameter 'OS' i.e. Operating System.
But there is not method called 'OS EXIST' or similar. Please suggest suitable method.
Thanking you all in anticipation.

Hi,
This can be done using user-defined function as well.
Code the function as...
if(Addr_Type.equals("HOME"))
   return "03";
else if(Addr_Type.equals("MAIL"))
   return "05";
else
   return "Invalid Address Type";
Here, Addr_Type is Input String Argument for this function.
Map this function between ADDRESS_TYPE and ANSSA.

G5 Dual 2.7Ghz Constant Noisy Fans

Hi there,
I'm really annoyed with this whole situation since Apple don't appear to have publicly acknowledged the noisy fans/chirping noise problems G5 users (with varying spec hardware) have been experiencing and posting about for over a year.
Anyway, here's the deal:-
My main spec is as follows: G5 Dual 2.7Ghz/4.5GB RAM/Mac OS X 10.4.6 installed on the shipped Western Digital 250GB SATA, 2nd internal 250GB SATA (Maxtor DiamondMax), 20" aluminium Apple Studio Display.
Since I performed the upgrade to 10.4.4 back in early May 2006 the fans have been constantly on as soon as the login window appears and remain at full pelt all the while the machine is on - clearly unacceptable and unusable. Fortunately for me it's not my only Mac although this is besides the point as I have now had an unusable machine for over a month and not been able to do any work with it - it is a production machine used for making music with Logic.
The bottom line is that I've not been able to make any music!
None of the suggested resolution methods that have been written about in the forums or elsewhere on the 'net (eg. installing CHUD tools etc) have made a blind bit of difference.
Furthermore, I have always had the chirping sounds since I purchased the machine in person from the Apple Store in July 2005.
For the past few weeks I was convinced that the fan problems were caused by the 10.4.4 update (when it started) and that the subsequent 10.4.6 update hadn't cured the problem.
Prior to this, I hadn't run a software update since December 2005 purely because I had heard horror stories from friends and other G5 users posting to forums etc. - if it ain't broke, don't fix it right?
I haven't really had the time to devote to trying to sort the problem out but I decided earlier today that tonight was the night to have a look at it.
Having spent all evening trying various things I am now convinced it is a hardware problem as opposed to being software related.
Here's what I tried earlier with the machine spec as above:-
1. Booted the G5 with Disk Warrior 3.0.3 boot CD
2. Ran all Disk Warrior tasks on both drives - eg, 0% fragmentation
3. Re-booted, fan noise still there from login window
4. Manually ran daily, weekly and monthly CRON jobs from Terminal - OK
5. Ran Disk Utility on main HD, repaired permissions - OK
6. Ran Disk Utility on secondary HD, verified disk - OK
7. Powered down
8. Removed all leads incl. power, monitor, all USB and Firewire
9. Removed 4GB RAM leaving 500MB stock RAM, reset the PMU
10.Ensured the removable fans (covering the RAM) were re-seated firmly
11.Replaced plastic 'door', attached monitor (DVI only) and keyboard USB
12.Re-booted, same problem, fan noise still there from login window
13.Attached Firewire HD with Mac OS X 10.3.8 installed
14.Selected Firewire HD in the Startup Disk system pref
15.Rebooted into Panther, same problem, fan noise still there from login window
AAAAAARRRRGGHHHHH!!!!!!!!!!
The last time I booted my G5 from the Panther Firewire HD (which incidentally hasn't been used since) was prior to me doing the 10.4.4 update on my G5's main boot drive and there was NO fan noise whatsoever!!!!!
Clearly I need to call and speak to someone at Apple tomorrow as the G5 is nearly one year old and I need to get this problem sorted out before it's out of warranty.
It just seems an odd coincidence that the problem started when it did!
Anyway, if any Apple techs or other G5 owners with a similar setup (specifically the dual 2.7) are reading this I'd appreciate a response or some advice for other things to try.
I'm just really frustrated and a little annoyed that having been a very content Mac user for years this is the first and only time I've ever had a problem with a piece of Apple kit.
Like I said at the top of the post, I can't believe the lack of acknowledgement on Apple's part as it would appear to be a known/common issue.
Just my £0.02.
Thanks for reading/listening.

Ok, take a look on your plastic shield, one of the bottom "tabs" should have a shiny metal coating of some sort, if it's gone or moved, then this could be the reason your fans are going "turbo".
If your fans are just at a high speed all the time, consider lowering your room temps to about 75ºF and see how it goes after a few hours/days.
It's most likely a wise decision to have the G-folks take a look at it anyway before it gets out of warranty. you might need a fan calibration or firmware change.
You still have a chance to buy AppleCare and get it registered before the 1 year warranty expires.
The Dual 2.7 is the hottest PM of the bunch, overclocked I would think.
You said the WD drive was OEM correct? Came with the PM stock?
Because the newer WD drives now have a new SATA spec that requires a SATA PCI card to function correctly in PM's.
Have you tried a complete reinstall of the OS?
Did you upgrade Tiger over Panther? (not good, less secure, previous exploits)
Do a backup, a clone of your boot drive to a external using Carbon Copy Cloner (check in the forums for their advice!) would be better.
the c boot off of Tiger install disk (not upgrade version) and from the installer menu Disk utility Erase w/Zero the boot drive (takes longer but writes are more reliable) and then reinstall Tiger, software update till clear, reinstall iLife '06 and all apps from fresh sources, avoid Migration Assistant (too blind, no app DRM copies) install files and see if your fan problems return.
Sometimes if Mac OS X is not operating correctly it won't tell the hardware to turn the fans down.
Don't install any OS/root level/admin password type programs or hacks until you've had a chance to clone that pristine puppy to a external drive (preferably 2) and keep it disconnected for safekeeping.
It's takes practically no time to option boot off a clone to recover, repair or reverse clone to the original drive. If your exploited, first c boot and Zero the infected drive before hooking up and option booting off the clone of course.

Trouble running hardware test on 07 iMac with noisy fan

Hello
I have an 07 iMac with a noisy fan- I've tried vacuuming out dust from the back but want to avoid taking it apart if possible...
I read online I should run the hardware test, but since I am running Mavericks the Apple support advice is to run the original OS X install disc and restart (holding down D or Option+D)...
Long story short I got a replacement disc from Apple (I'd lost the original) but the iMac ejects it when I restart following the process above... could it be my bluetooth keyboard? Hopefully not since I no longer have the original hardwired one... or does anyone have any other ideas for either how to get to the hardware test... or fix the fan (without a third party app just stopping it)
Thanks!

Try holding down the Option key to get the one time boot manager screen then select the AHT. Not sure as Apple moved it around on different install discs but it might be on the Applications discs and not the OS X discs.

I'm getting a Plugged in, not charging message after replacing the CPU fan

I just replaced the CPU fan on this notebook last night and finished it today. Its running perfectly at the moment.
The problem is the windows Task bar on my desktop says "Plugged in, not charging" when I mouse over the battery indicator there. I've tried many things to fix it, from uninstalling or disabling the drivers for the devices involved (the ACPI battery and AC adapter) under Windows' device manager, to swapping out with my spare battery.
I've also switched power plans on the off chance that could have been causing some kind of battery charging setting. This did not fix it. The AC adapter works. I've been running this notebook for about two hours now searching for a solution, it just won't charge the battery. I've not tried observed it enough but I believe it will charge while powered off, but not while on. The orange LED indicator by the AC adapter port glows when the machine is off, indicating that it is charging.
I have a feeling the whole "uninstall device drivers for the battery devices" idea is a thing of the past. Everything I found which suggested doing that also mentioned Windows Vista, which at this point in time is a relic (July 2015). When I was replacing the CPU fan, it did get frustrating at times but everything is intact apart from some case clips and a few other plastic case parts. I have reason to believe everything is connected too because its still powered on, meaning its getting power, but it isn't going in to the battery.
Symptom summary:
Batteries: OKAC Adapter: OK
MOBO: PROBABLY OK
ME: NOT OK xD

Hey srkv121,
welcome to the forums
On
1. Optimized battery run time, the energy managment completely charges the battery to ensure maximum battery performance
2. On best battery health, energy management charges only 50% of the battery, it ensures maximum battery life but not performance
hope this helps
regards
Lets make 2015 the year of the #DO
