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.

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:

I have done some research on line and I have the following questions:
RAM
1) What is the maximum RAM my mac can take without causing problems. Apple mentions that the maximum RAM is 4GB (2 x 2GB) but I have seen mentioned in threats that up to 8GB have been installed.
2) The RAM quoted in the specs from apple is DDR3 PC3-8500/DDR3-1066. Could I use a faster chip such as DDR3 PC3-10600/DDR3-1333 or is this upgrade not advisable.
Hard Drive
1) Is there a limit to the maximum capacity re hard drive. The maximum apple used to offer this model was 320GB. I would ideally would like to go up to 500GB to 1TB.
2) The specs of my existing drive are: 160GB 5400-rpm Serial ATA hard disk drive. Could I get a faster disk, say 7200 rpm to increase performance and will this have any significant impact on battery life and heat?
Further more any recommendations in terms of any of the above welcome.
A lot of information but I wanted to offer all the info needed for meaningful advice.
Thanks in advance.

Hi Christos77,
I also have a late 2008 13 inch unibody MacBook - mine has the 2.4GHz Intel Core 2 Duo processor and a 250GB Toshiba hard drive. At the beginning of January I upgraded my RAM from the original 2GB to 8GB from OWC and it made an enormous difference to the functionality of my machine. In fact, it turned it from being almost unusable to working in a reasonable way.
The recent death of my Time Capsule has prompted me to re-think my setup and, basically, what I need is a drive with greater capacity than my original Toshiba 250GB that the MacBook shipped with. I'm currently working with only 11.65GB of Available disk space so I need to do something pretty quickly.
I've been researching over the past couple of days and decided that my need for storage is greater than my need for speed so I've decided to replace my existing HDD with a new HDD instead of going down the OWC 'Data Doubler' route.
I, too, thought that the 750GB WD Scorpio Black 7200 rpm drive would be the best (and most cost-effective) solution but I've read reports from some users that it was either noisy and/or hot. However, none of these comments came from users with a late 2008 MacBook.
I would be very grateful if you could confirm that, after almost twelve months, you're still happy with your WD Scorpio Black drive in your late 2008 MacBook?
One last question ... when you now check the Serial ATA details in the System Report, does it still show your new WD hard drive having a 'Negotiated Link Speed' of 1.5 GB or is it now SATA 2 (i.e. 3GB)?
Many thanks for your help.
Cheers
Tricia
BTW I've been running OS X 10.7.x on my system since it came out - no problems at all with it - am thinking of upgrading to 10.8 because I've read that it takes a little less space and is more efficient in memory management - but will have to check a few more things first before I decide to do that!

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.

Do you think my macbook pro fan could be broken?

Earlier today when I opened my laptop the screen was black and it appeared to be shut down. I hit the restart button and when the screen came up it said that I had "shut off my laptop due to a problem", though I did not manually shut it down. It was working 100% fine yesterday, so I'm not sure what could have happened to it. I know it wasn't my battery, because I had a full charge prior to shutting it and upon restart I still had a reasonable charge. I was more or less ignoring my laptop's unusual pop-up until I noticed that my computer was feeling much hotter than normal, so I checked iStat pro to look at temperatures. The CPU temp was around 82 degrees or so when I checked, while I was playing a videogame, which doesn't seem too high but the area around my keyboard felt much hotter to the touch than normal. What is really concerning me is that iStat says my fan is running at 0 rpm, even while I was playing a graphic-intensive game. The CPU is down to 65 degrees since I have stopped playing the game, however I have heard that your laptop will shut itself off to prevent overheating, and I'm wondering if this is what happened to my laptop sometime between yesterday and today. Does it sound like my fan could be broken? There isn't an apple store very close to me and my warranty just ended so I'd rather work it out myself if possible. I don't believe it is a faulty sensor either as iStat gave me temperature readings for everything. If you think my fan is broken, do you have any advice or know how much it would cost to fix/replace?

Good detective work.
I don't believe that 80ºC is extreme for occasional use, but over extended periods of time, this can stress your machine. I beleve you should visit your local Apple Store. They can determine if the fan is broken.
In the meantime, I could avoid:
- CPU-intensive activities like 3D gaming for extended periods of time.
- Using your notebook on your lap. That can raise its temperature thirty or more degrees.
- Dust or dirt can choke the fans, increasing temperatures and even the risk of fire.
Replacement of a fan is not very expensive, if it comes to that. You can also do it yourself:

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.

Macbook Pro Fan Speed

Hi. I was having some trouble with my temperature of my MBP, but I somewhat solved it using Temperature Monitor and smcFanControl. I turned the fanspeed to Higher RPM in the smcfancontrol menu, and my temperatures are down from ~95 celcius to ~65 celcius (when playing Minecraft / other extensive tasks.)
Now, I would like to bring them down more (should I?) because I feel 65 c - 70 c is still really high...
So, my only question is: In smcFanControl, the Higher RPM setting is 4000 RPM, should I change that to 5000 RPM? I know it would help, but, can the fans handle that?
Thanks in advance
Could 70c (max) shorten it's lifespan?
(sorry I just am extremely extremely paranoid)

I am seeing a lot of negative talk about third-party software to control fans:
Istat menu 5 is good.
It conforms to apple's SMC; this means that it will never allow the fans to go slower than what SMC is asking, thus your computer will be safe using this software.
In contrast I have a Macbook Pro fan controller for bootcamping Windows 7 called MacFanx64.exe (64 bit) that requires you to understand command prompt.
It's nothing difficult, you just need to make sure that you enter parameters properly.
The only way I see one of these damaging any hardware components would be if you accidently told the fan to spin faster than the max speed.
I would agree that for OS X you aren't going to really need this because the engineering on the SMC isn't terrible, but if you happen to have SMC screw up like it sounds like you had, there's no way to know it unless you feel it getting really hot like that which I'm sure isn't great for your MBP.
Therefore having a monitor system is helpful because you can see the temperatures constantly.
Now for Windows 7 bootcamp it's a whole different story.
There is something wrong with the drivers that control SMC for bootcamp because the computer will get hot fast even in idle.
I was marking temperatures around 60-70 C just in idle - the fans still stay at 2000 rpm.
If someone finds something better than MacFan for Windows 7 bootcamp let me know.
Moral of the story, if you pick a good third-party application you're not going to harm your computer.
Think of it like a second line of defense.
Last but not least, if you're still having this problem do an SMC reset.
Apple has instructions on how to do it, just note that you need to pay attention to whether your MBP has a removable battery or not when doing SMC reset.
Cheers

MacBook Unibody A1342 no power after water damage to logic board

MacBook Unibody A1342 no power after water damage to logic board
Ive sustained damage to my logic board after water damage. Can anyone tell me if it can be repaired or what the parts which have fallen off do(looks like 2 tiny capacitors?) . Magsafe has green light and battery charges but machine shows no other life signs. any help would be most appreciated thanks

@CoccoBorg:
I need your help, please. I spilled wine on my mid 2009 unibody macbook pro, now when I power up I see Hard drive light On, I hear fan noise, but don't hear any startup Apple chime and nothing on display, I cleaned the logic board with 91% alcohol, but that didn't change anything. Before cleaning the logicboard, their were no signs of wine on the logicboard, but there was a lot of wine on the keyboard black sheet.
My guess is:
1. The keyboard might be causing this behaiour, I wan't to bypass the keyboard, can you please confirm if these are the right power pads on logicboard?
http://www.ifixit.com/Answers/View/106612/Where+are+the+power+pads
2. You mentioned something about fuses, where will I find them on logic board?
3. Any othe suggestions will be highly appreciated.
Thanks

Macbook pro fan running slow

macbook pro fan is running slow and hot. it fluctuates between 212 and 375 rpms. heat rises up to 104c. do i need to replace the fan?

Before I suggest advice, I urge you to keep your machine under 160F at all times. I don't want to sound like an alarmist, but you can seriously damage your machine with that kind of use. Some solders melt at 225F, weaken at 190F.
You may have to replace the fan - or you may need to clean the inside of your machine and fan. It's hard to tell without inspecting your machine.
Or you may find that you need to get a different browser, and become more aware of temperature; laptop machines are much more sensitive to termperature issues than desktop Macs. Some day, you'll thank me for that advice.

Ever since my upgrade to lion 10.7.3, and iCloud, my macbook is running extremely slow. What can I do? It doesn't seem like my contacts are pushing through to the computer from iPhone.

Ever since my upgrade to lion 10.7.3, and iCloud, my macbook is running extremely slow. What can I do? It doesn't seem like my contacts are pushing through to the computer from iPhone.

Then your basic issues are: too little RAM, incompatible software, dysfunctional installation.
Add more RAM or kill as many programs that you use until the computer is running normally.
See App Compatibility Table - RoaringApps. Upgrade any old software.
Reinstall OS X:
Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Reinstalling OS X Without Erasing the Drive
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Alternatively, see:

Can i hook up my Macbook unibody to my iMac (2007 model), and use them as one computer ?

I have an iMac 20" which i bought in 2007. Then in nov 2009 i bought a white macbook unibody. I've got ableton Live running on both computers and what i want to do is, use my iMac as a main computer and my macbook as a support computer. I have a few questions.
1) Can i upgrade the processor of my iMac ?
2) Can i use my Macbook as a second screen ?
3) Will the upgraded processor help in the performance of the running sofwares ?
Please help!
Billz270

1) No. The iMac's processor is part of the logic board and cannot be replaced with a different one.
2) No. The MacBook does not have video in capability.
3) It might, but see answer 1.
Best of luck.

What is causing my Macbook Pro fan to run constantly?

Hello. Recently my Macbook Pro fan has begun to run constantly at high power. I've checked the activity monitor and even when there is little RAM or CPU this occurs. I am wondering if the issue is the hard drive because the I am seeing spikes in disk activity at random times even when I am not using the hard drive. The computer is actually heating up when the fans are on at full power, so this also leads me to believe it could be the hard drive. I have already tried resetting the system management controller. Any other ideas? What should I do about this?
Thanks a lot.

Try raising the the the machine with wood, or , plastic botttle caps t get it up an inch or so, that way there is more air flow under the MBP to help with the air flow to help keep the cooling more een. Hope this helps.
