MacBook Unibody Fan extremely noisy

I made a topic on here last year sometime about my macbook (bought in November '08) overheating. I took it back to the shop and after a lot of persuasion (because it wasn't overheating at all when the shop i bought it from kept it for a week) I got a new fan fitted by Apple. Now my fan is getting really noisy again. It's not overheating or anything, it's working perfectly fine apart from the noise. I've updated all my firmware and that hasn't helped at all. When I start it up it's just a quiet noise but when I move it or try to watch videos on youtube it gets really noisy. I thought that it might be that the fan was unbalanced but I'm not sure. I recorded the sound of the fan with my mic on the macbook so you can hear how loud it is.
http://tinypic.com/r/16c4daf/6 - This is the "quiet" sound
http://tinypic.com/r/33y40gy/6 - This is the extremely noisy sound
My warranty expired in November but I got the fan replace about a month before that. Do you think the fan would be under warranty by Apple because it's a new one or is it not because the warranty of the macbook has expired?
Has this happened to anybody else? If so, how did you solve the problem?
Should I take it back to Apple and see what they could do?

"Should I take it back to Apple and see what they could do?"
Sure.

UCS C220 M4 rack server extremely noisy

Hi,
I am preparing a UCS C220 M4 with windows 2012 for a client.
The server is extremely noisy, I mean much more than any other rack server I have ever seen.
All the fan are working at highest speed rate as if the server had to urgently cool down.
The question is: Is this normal ? Is the server broken ? Is there an option to lower the "fan-policy".
And how is this done.
Best regards,
Javier Conejo

The fan policy can be lowered if you go to the Server> Power Policies> Fan Policy.
Here is the explanation for each option:
http://www.cisco.com/en/US/docs/unified_computing/ucs/c/sw/gui/config/guide/1.5/b_Cisco_UCS_C-series_GUI_Configuration_Guide.151_chapter_011.html#concept_8CB787DF70304E98BE25D120466418B9
Balanced This is the default policy. This setting can cool almost any server configuration, but may not be suitable for servers with PCIe cards, since these cards overheat easily.
Performance This setting can be used for server configurations where maximum fan speed is required for high performance. With this setting, the fan speeds will run at the same speed or higher speed than that of the Balanced fan policy.
Low Power This setting is ideal for minimal configuration servers that do not contain any PCIe cards.
High Power This setting can be used for server configurations that require fan speeds ranging from 60 to 85%. This policy is ideal for servers that contain PCIe cards that easily overheat and have high temperatures. The minimum fan speed set with this policy varies for each server platform, but is approximately in the range of 60 to 85%.
Maximum Power This setting can be used for server configurations that require extremely high fan speeds ranging between 70% to 100%. This policy is ideal for servers that contain PCIe cards that easily overheat and have extremely high temperatures. The minimum fan speed set with this policy varies for each server platform, but is approximately in the range of 70 to 100%.
There are still some PCIe cards that cannot be monitored and cause the policy to be "ignored" so the server can be kept cool (I'm not saying that is your issue, I am just mentioning it)
Open an SSH session and enter the commands:
"connect debug-shell"
"sensors"
Paste the output here for the FAN sensors (they will have the word "FAN" on it)
Be sure you air flow is not blocked at all by doors or cables.

Extremely noisy output from Xmod wirel

Let me start by saying that I think the Xmod wireless is a great product. I have bought other products which claim to wirelessly transmit audio over short ranges, and all of them have a lot of interference. The Xmod wireless is not like that at all, the sound comes in crystal clear on the other end. I also love the fact that I can change tracks / volume etc using the remote on either the transmitter or receiver.
One thing that I like to do however is play my music in two locations at once, so if I move from one room to another the music keeps playing.
Currently, I have the transmitter hooked up to my computer via USB, and then I have the line out on the transmitter running to the line in on my computer. This allows me to listen to audio on on my computer speakers and also at the wireless receiver location.
The problem is that the line out from the Xmod wireless transmitter is extremely noisy, so if there's a quiet part on the song or in between songs, I hear tons of what'd I'd call electrical background noise.
I've tried eliminate things by plugging the line out of the transmitter directly into my speakers which did not help, I also tried skipping USB and plugging the transmitter into an electrical outlet and using the line out from my sound card, and that didn't help either.
Does anyone have any ideas of how to eliminate the background noise? If anyone else has the Xmod wireless, can they please tell me if this is a problem they also have? Curious if it may just be a problem with my specific unit.
The strange thing is that the wireless receiver does not suffer from this problem, only the line out from the Xmod wireless transmitter.
Thanks for any help anyone can provide!

- Nope, I contacted support who could only provide me with canned emails about trying to unplug the unit and plug it back in or other tier type suggestions.
They finally authorized a replacement unit, but the replacement unit suffered from the same problem. I can only assume that the problem exists in all units.

Fan very noisy

Hi I bought a new Macbook 13" with 2GB RAM and 2.4 Ghz dual Cpu.
I found the fan very noisy and alvays conne4cted.
Can anyone help me What can I do ?

Try resetting the SMC. [http://support.apple.com/kb/ht3964]. The SMC controls the fans. If not, Take it to your nearest Apple Store or Apple Authorized Service Provider. There may be a disconnected sensor in which case the computer would ramp the fan to full to avoid overheating.

CPU Fan controller / Noisy CPU Fan

Hi All.
I have the GD65 and the FX 8120 and the CPU fan is a bit noise( ~5750 RPM ).
Is there a smart/PWM CPU fan controller in the bios ?
The end goal is to only have the CPU fan get noisy when under load and not all the time.
Thanks in advance.

Quote from: Bernhard on 30-September-12, 13:50:46
i.e. set you target temp to 40C and a minimum fan speed of 25%. That means your fan will run at 25% of its max rated speed until the CPU temp is at 40C, at which stage it will start spinning up to higher speeds.
The bios is the new fancy GUI and mouse one.
I found a a setting that seams to match your description: "Main->Hardware Monitor->CPU smart fan controller" and that then showed a setting called "CPU min.fan speed()"(looks like a function call to me).
I set the "CPU smart fan target" to 40C and the "CPU mun.fan speed()" to 50%.
So now would that mean that the CPU fan will spin at a minimum of 50% at 40C and slower when when less then 40C ?

My macbook pro 2010 extremely noisy and a warning flashed on the screen about a power or battery issue- can you help please?

My macbook pro 2010 has started getting extremely noisy in the last few months and I had a strange warning flash up on the screen a month or so ago about a power or battery issue… can you help please?

Calibrating a 2010 MBP is not required. All it will achieve is putting an unnecessary cycle on it and shortening its life:

Extremely noisy fan and burning motherboard

Hi, I got HP dv5 2070us laptop a couple years ago and decided to dust out the fans and stuff. So I brought my laptop to the computer service office to clean it.
After the clean up, my fan got even louder than before! Roaring like crazy.
So I tried to figure out what was wrong with it. Downloaded some software like Speedfan and Aida64 to check out the temperatures of the CPU, motherboard and so on. Both mentioned programs shows that my motherboard is 87C (189F) ! and this temperature is fixed, doesn't change all day long, while the CPU temperatures are changing.
Maybe this is the reason of the noisy fan. What is more, computer doesn't shut down. The screen is black but fans are working even after 10mins. The only way for a completely shut it down is to press the power button.
Does anyone one how to solve this problem?

Hello Merc,
Try figuring out what's causing the noise.
Is it a vibration? Try a mechanic's stethoscope if you can find one; or just use a thin, long bladed screwdriver to amplify the noise. Cleaning the fan blades of accumulated crud will improve their balance. Occasionally, sheet metal or a loose screw will pick up the vibration and amplify it.
Is it a bearing or bush that's starting to wear? Maybe it's new fan time - nothing is forever!
Is it the rush of air? They make quieter fans, although the quiet ones don't always cool as well. (I have a dual 800MHz Quicksilver that was fitted with a quiet fan, and you could have grilled bacon on the heatsink - I wound up with a high-powered fan that I can hear in the next room.... but a cool Mac!)
Try measuring your fan (in mm) and searching for fans; I don't remember my exact parametres, but I turned up quite a few. Compare using RPMs, dBs, and CFM as guides. Come back and make us all experts!

Extremely noisy fan - dv2-1133AX

I recently purchased a dv2 1133AX last Nov '09. lately I've been hearing a rattling noise coming from the fan continously.
Please advise on what should I do to troubleshoot this problem.

Fan has become extremely noisy...whirring

This just happened a coupel days ago. The fan is located under the power button and vents at the bottom and back. Hot air is coming out. Italso speeds up and down at times depeneding on what I am doing...I think. IS the fan going to give out? Is it dirty? Bad barings? I cleaned it up using Malwarebytes in case it was malware. I sprayed some canne air into the vents to clean any dust ans it may have helped a bit. What do I do? Very used laptop for work.

Hi,
Looks like it's getting hot. Keeping the vents (inlets & outlets) clear may help. Many people use coolpad (me too) to reduce few degrees. You may have to look at the fan itself too and use a good air pressure can to blow dust away.
Hope this helps.

Extremely noisy and continuous fan - MacBook Pro 15"

Hi there,
After spending an entire afternoon trying to figure out why my MacBook Pro 15" got so loud over the last few days, I decided to post this message being completely desperate...
I have seen and tried everything from Apple Support to Apple Users... Restart, shut it down, reboot the SMC, reboot the PRAM ! Nothing worked !
My laptop is only two years old, and I've done all updates including installing the new Lion iOS X... This noise has started about three days ago and I don't get what is happening?
No printers, no software using a lot of CPU in the Activity Monitor... Also, iStat says 96% Idle CPU, fan 6939 rpm...
Help !!!! It's unbearable !!!!

So AHT never did run, and you'll need the original DVD that was shipped with your computer when it was new to run AHT. If the hard drive has been reformatted at any time, that explains why AHT isn't there at startup without the DVD.
Just to be clear, AHT is not going to fix anything. It's purely a diagnostic tool, not a therapeutic one. Once you're finally able to run it, choose the extended version, make an exact note of any error that it reports, and post the error here. If there is any error, the machine will indeed need to be repaired.
A Genius Bar appointment is free, and the Genius will have testing software not available to civilians like you and me to run if you can't find your original disc containing AHT. So don't lose any sleep if you can't put your hands on it — just make an appointment and take your machine in.

Extremely Noisy fan

hi, for the last while now, my Power Mac G4 has been really loud when running. It used to be a lot quieter and I think a lot of it is due to the fan. Can I replace the fan? If so, what do I need to replace the fan with and where would I find it to purchase? If the loudness of the computer could be caused by other factors as well, what would those be and are there any suggestions on how to get it to run quieter like it used to?
I have the dual 800mhz quicksilver if that helps with what's compatible for this model.
Thanks in advance!

Macbook Air suffering loud fan, extremely slow

Hi,
I'm using a MBA Mid 2013 (warranty ended by June 31), and below is my story (verry sorry if it's long and waste your time).
By the third week of June, my MBA got a problem with the sound. Since it's still in warranty duration, so i took it to an Apple authorized service center in my place. They kept it for a week, and after that, my MBA's sound problem gone. But:
Actually, I made some quick tests in that center, and everything seems normal. So that, i closed my MBA and left the center.
When i got home, i opened my MBA to retouch some photos, but the MBA is extremely slow (opening a photo in Preview took around 1 min), and the fan went crazily loud.
I opened the Activity Monitor. Surprisingly, there's a process named kernel_task was taking ~300% of the CPU, thousands of the CPU time.
I did some research in the community, and found a solution: "Reset SMC". I tried that solution and magically, the problem has gone. So that, i thought it was just a software problem, instead of a hardware one.
The warranty expired...
The first half of July:
Everything seems OK and my MBA is stable.
The previous week:
The kernel_task error seems back. At first, i repeated the SMC reset solution and it still worked. But few times later, that solution turned useless.
Although my Mac was still usable, but during the kernel_task error, it's very slow that i could not do anything. Sometime, the kernel_task automatically turned normal (and my Mac is fast again).
At that time, i tried a list of other solutions and found something:
- Reset PRAM: The key combination was very hard to be succeed. Mostly, my MAC normally boot to the OS.
- Safe mode: Same.
- Recovery: Same.
- Apple Hardware Test: Same. But, in a success one, the result said that there is a problem with my thunderbolt (When i check in the System Information, the thunderbolt part said that No Hardware Found...??).
So, I guess that there's few problem with the OS.
So that, in the previous weekend, i tried to re-install the OS (Maverick). My Mac seems normal again.
But today, after a sleep - wake cycle (close, and open the Mac screen), the kernel_task disaster was back.
In this evening, i tried to re-install the OS once again, with a different installation. But... the problem seems more serious.
When i booted by a usb to install OS, the fan still loud and my mac still slow, which lead to the OS install could not be completed (stuck at 13%). And now, i almost cannot even choose the Startup Disk. Although i pushed and pressed the option key, my Mac will automatically boot to the Utilities for restoring the OS (because i formated that Mac partition).
Now, i'm very disappointed and confused. My mac is slow and the fan is loud anytime, i cannot install the OS. A software (perhaps?) error now turns to a hardware (perhaps?) error?
Could someone please tell me what is that error, and is there anyway to fix it?
Thank you in advance!

Well, when you use a secondary display you are making the graphics processor work harder. That would explain the fan noises. Also, be aware of where you place the comptuer. Try not to block the back so it can vent and not place it near other warm devices.

Satellite Pro P100-465: fans are noisy

Hello,
I have a P100-465 running XP Pro on it. I have had the laptop about 6mths now and the one thing I have noticed about this laptop is that it is SO noisy. When using the laptop the fans go on and off constantly....even if I am not doing anything resource hungry. is this normal? I understand that the machine is powerful but I can't believe this is normal.
I use to have a P25-S670 and the fans use to come on every now and then to keep the machine cool but this new laptop is INSANELY annoying. As I am typing this the fans go on and off every few seconds. It sounds like the fans RPM increases substantially but only for a second or two and then it drops down. In the BIOS I have even set the option to silent mode instead of performance mode but this hasn't made any difference. I am running all the latest drivers and firmware.
Can someone help please as this is driving me NUTS! ;-) Is there a way to control the fan speed/noise from within Windows? I remember on my P25 I could change the power options to silent mode and it made quite a big difference.

Hi mate,
did you already cleaned your cooling system? Maybe that could be the point since such small ventilation systems are susceptible to be clobbed with dust after a while of running.
A idea would be to give your machine to a technician and ask him to clean your machine and to put some new cooling grease on the CPU.
That should help and prevent your machine from overheating or excessive fan noise.
Cheers

Mac Mini 2011 Fan is Noisy During Streaming Video

Mac mini 2011 2.3 GZ. When I watch Youtube streaming video fullscreen or video chat with someone on Skype, the fan kicks into high gear and gets really noisy. Fan gets to about 5200 rpm and CPU up to 75C. I don't get the heat or fan noise during avi/Quicktime/VLC playback, or an Skype, audio alone. I don't recall this on my 2009 Mac Mini. Is this normal?
Only variable is an 8 gigabyte RAM upgrade.
