Macbook Pro (Cooling Fan?) Noise - Now Louder!

A few weeks ago my macbook pro started making a noticeably louder noise (I suspect the fan). Now it has started to get louder over the course of a minute until it sounds like it gives up and the macbook goes silent! Can someone advise me on what to do?!

You may perform a SMC reset:

If that does not solve the problem, run an Apple Hardware test to see if that will give any clues:

Retina Macbook Pro strange fan noise

Hi all, i just got my retina macbook pro 2 days ago, however when starting it up for the first time there was a strange noise coming from the computer (probably fans), it was like a blocked fan kicking in loudly but only for a few seconds. I figured that it was nothing but it came back when i used it today and i noticed that this sound is only present when the computer is warm. It only comes for a few seconds and then fades away, is this normal? I'll try to post a recording up here if i can.

I have the same problem with my MacBook Pro Retina . . . took it into my local Genius Bar, where a nice woman identified it as noise from one (or both?) of the fans. She took it apart, removed some debris (couldn't have been much, after a couple of months) and . . . the computer continues to make this annoying noise.
I believe this must be a serious design flaw on Apple's part, and that they don't know what to do about it.
We can hope that the noise is merely annoying, and not a danger sign.

MacBook Pro Default Fan Noise

Hey guys,
I just purchased my new 15 inch mid-2012 MacBook Pro yesterday and am loving it so far. My only concearn is the fan noise. Are the fans supposed to run non-stop regardless of what you're doing? If so, is it normal to be able to hear the fans in a quiet room? It's not loud, just a little breeze.
Thanks

New computer.
Spotlight indexing can cause fans to rev up a bit. That is normal.

Macbook pro 13inch fan noise

hi,
One week old 13inch Macbook pro first problem no usb ports working or sd card reader now sorted, but now I seem to have, what I think is a costant fan noise coming from the top left side,as soon as start up, so no load on the cpu what so ever, and this noise was not present for a week.

Hello, LeaseBL.
Thank you for visiting Apple Support Communities.
Try resetting the System Management Control to see if the fan noise ceases. Also, make sure there are no obstructions to the fan as well as the portable is on a flat surface when in use.

A1212 Macbook Pro Cooling Fan Speed / SMC / Service Battery

Background:
I've owned my A1212 Macbook Pro Core 2 Duo since launch (Thanksgiving 2006 I believe). For some time now the temperature has been quite warm - more recently my right cooling fan has intermittently sounded like a jet engine and failed to speed beyond 1,500-2,000 rpm intermittently.
1. I ordered the correct cooling fan for A1212 right and replaced.
2. When I rebooted Macbook Pro here is what I see for temps in hardware monitor
AMBIENT TEMP 31C/88F
CPU A 44C 111F
CPU CORE 1:36C/97F
CPU CORE 2:39C/100F
"SMART DISK" — [DOES THIS MEAN THERE IS A SENSOR THAT IS NOT REGISTERING]
The hottest temp recorded is 109F/ CPU A temperature diode
The new cooling fan is majorly cooling the mac much better than prior fan.
3. I can't find ANY way to stop the mac from running both cooling fans at 6,000rpm
a) reset SMC (tried holding down power button 20 seconds after disconnecting battery
b) reboot
c) remove smcfancontrol
d) use smcfancontrol
e) monitor with temp monitor, hardware monitor, istat pro
f) no runaway processes - not even hot
4) I notice ( this was also showing up before install of new fan) in my battery icon it indicates "Service Battery" - while I do have a 4 yr old computer there was a recall on batteries so this battery is maybe 3 yrs old and I usually use computer plugged in.
I do not have my snow leopard boot dvd readily available to run hardware test on sensors, however techtool pro does not report any issues. I have not found any terminal commands to force the fan speed down nor any indication I have any apps that are accelerating it.
It appears that my fan speeds are accelerating shortly after power up - before OS X is even loaded completely - and never slow to normal speed except when mac is asleep.
IS IT POSSIBLE TO CONNECT THE FAN INVERTED (THE TWO PINS) MESSING UP ABILITY TO CONTROL FAN SPEED?
IS IT POSSIBLE THAT I INADVERTENTLY BROKE SOME SENSOR "SMART"?
I am thinking more and more that this is hardware related like a sensor. Any assistance would be greatly appreciated, while I don't have a Jet engine I have a very noisy mac

Hi N,
SMART reports on a number of checks on the HD. I don't believe that's any part of the current issue.
I agree with you that my first inclination is toward a sensor issue; by default, if the sensor's are not reporting properly, the fans run full speed/6000RMP.

Brand new macbook pro retina - fan noise when running hola?

Hi everyone, I need some help here please!
I have a brand new macbook pro retina 13 - just bought in January this year - and have had no problems so far apart from the wifi dropping occassionally.
So I just downloaded hola unblocker for firefox but whenever I stream anything using it on netflix my fan starts whirring so loudly - it's never even made a noise before! and I can feel the base of the mac getting hotter. So I've closed hola/firefox and it stops after a minute or so. I've tried a few times again with the same problem.
I'm just using it to watch US netflix so probably not technically legal anyway.... but other friends manage it no bother - do mac's just know I'm doing something wrong? haha
Thanks for any advice.

Try running Activity Monitor (in the Utilities folder). Click the Energy button at the top and then stream a video. Watch the Energy Impact.
I suspect what you'll see is that your rMBP is doing a lot of work while you're streaming the video, and that makes it get hot. The fan struggles to dissipate the resulting heat in order to prevent damage and makes noise in the process.
It may also have a guilty conscience.

Macbook pro hot fan noises

I just bought a MacBook Pro 13" 249GB with Retina Display a few weeks ago. Before, I had the MBA (I took it in because one of the USB ports never worked). I am just a little concerned about the hotness. Sometimes it gets really hot and the fan kicks on to cool it off. The thing is, I'm just surfing the internet, not even doing that much of a laborious task. I understand that computers get hot and naturally cool themselves off, but this never happened this often with my MBA.
Yes, I will admit I do spend the nights/mornings on the bed, which isn't that great for the ventilation, but even when the Pro was on the desk the fan went on.
I just want to make sure that I don't have to take my Mac to be repaired again for a problem that was there from day 1.
Also, what would be some good programs to check the temperature? I downloaded IStatic Pro, but when I opened it I didn't see anything. (maybe because it was a widget??)

First perform a SMC reset:
http://support.apple.com/en-us/HT201295
I recommend iStat menus as a temperature monitor:
http://bjango.com/mac/istatmenus/
Open Activity Monitor to ALL PROCESSES and set CPU to display values from high to low.
When your MBP gets hot, open Activity Monitor and see what applications are being resource hungry and check what temperatures are being generated. You are welcome to report this information for evaluation.
Ciao.

Macbook pro cooling fan runs continuously after software update

I updated Mountain Lion last night (Mar 15, 2013). I forgot the version number, but it was 10.8.? I think.
After restarting the computer this morning, the cooling fan suddenly shot up, making crazy noise. It didn't come back, so I had to turn the computer off with physical switch. While the fan was running, battery was draining so fast. I began with 100%, but went to 65% in 45 minutes. Such thing never happened before. I did not run the computer with complicated Apps when it happened. I was using Safari and Logos Bible software. Does it have anything to do with the new software?
It is quiet right now, after restarting. I paid more than $2k for this computer last fall. Didn't have any problems yet. But it happened all of a sudden. Anyone has any idea??

Next time this should happen try a SMC reset:
http://support.apple.com/kb/ht3964
If no success, look at Activity Monitor to see if you have a 'runaway process' and terminate it if not required by the OS or perform a restart.

Macbook Pro 2010 fan noise

Yesterday, my macbooks fan all of a sudden started rattling and making lots of noise, just like in this video: http://youtu.be/IdQvf3WPKKA
Restarting the macbook didn't work as the noise would come right back.
I shut it off for the night, with the idea of trying to find a repair center today (my warranty is long gone). But now it doesn't make that noise any more.
I can still hear the fan rattling really silently.
How do I know if the fan is working properly and not overheating the laptop?
Do I have to replace the fan?

Run Apple Hardware Test.

How does the MacBook Pro cooling fan work?

Is slotted area on the back of the MBP an intake or exhaust area?
I am buying a notebook cooler and I want to make sure I buy a compatible cooler; that is to say one that doesn't blow hot air into the intake or take in the hot air form the exhaust and blow that across the base of the computer.
Thanks

They blow out the back of the laptop. So I don't think the external fans blowing upwards will blow air back into the MBP. Of course this is just a guess since I do not have one to try but I don't think it will defeat the internal fans. In
my own opinion I don't think the external fans are really neccessery unless you are running your CPU at 100% or more for hours at a time.

Are MacBook Pro cooling fans on at start?

My mid-2009 MBP has a noisy fan -- the one closest to the middle. It is easily fixable but something else concerns me: When I start the Mac, at least the noisy center fan starts up right away (I don't know if the fan on the left starts). I thought the fans were not to start until the internal temperature reached a certain point. Is there another problem?

The fan(s) will always be running at startup. I believe the minimum speed on newer models is 2000RPM.

Macbook pro retina start to make loud fan noise and work slow

I bought macbook pro retina display less than one years ago. For some reason my macbook pro has been making loud fan noise for about five mounth. Whenever macbook pro makes the noise, all the programs start to run slow. Typing, opening safari, and etc takes forever. It takes 20min to 40min for the noise to stop. At first, the macbook pro made noise once or twice in a day, but now it's making the noise frequently; It happens every 2-3 hours. It got to the point where it start to annoying me. Is there a way for me to fix this issue? If not, can I use one year warrenty to fix this problem? Thank you.

If your Mac works slowly when fans turn on, it's quite possible that there's a process which is eating the CPU and/or RAM.
Open Activity Monitor (in /Applications/Utilities), select "All Processes" above "Show" (in the toolbar) and then, order the processes by CPU usage. Do you see any process which is consuming more CPU or RAM? If so, tell us the name.
Additionally, you can reset the SMC > http://support.apple.com/kb/HT3964

MacBook Pro A1126 fans goes 'crazy'

My MacBook Pro A1126 fan makes a lot of noise when I use it for intense gaming for hours,
My Mac specs
OS - Mac OS X Mountain Lion 10.8.4 & Windows 7 Ultimate 32-bit ( Boot Camp )
Processor - 2.2 GHz Intel Core 2 Duo
Memory - 4 GB 667 MHz DDR2 SDRAM ( Originally 2 GB, upgraded to 4 GB )
Graphics - NVIDIA GeFore 8600M GT 128 MB
How do I stop the fan noise or at least reduce the noise,by the way it's from the left fan & there are two fans in the MacBook Pro...
Thanks in advance!

Games use a lot of CPU/GPU resources and that creates a lot of heat The fans are supposed to spin faster in order to dissipate that heat. It sounds that what you are experiencing is normal.
If one fan is significantly louder than the other, Courcoul's advice should be taken.
Since you have a 6 year old MBP, it may be a good idea to open it up and see if there is dust, dirt and debris inside that should be cleaned out. That could have a very positive affect in the cooling process.
Ciao.

Macbook Pro - Noisy Fan ?

HELLO! I've just purchased a refreshed 15'' MacBook Pro at the Apple Store recently. I'm in love with it!
Just a few days ago, my MacBook Pro has been making these loud noises coming from the right side of the speakers. I'm assuming it's the fan because whenever I would run heavy programs like Photoshop and a few other programs the sound of the right speaker gets pretty prominent. And whenever the computer isn't running anything, you can hear a faint sound of that noise. I don't know how I can exemplify the sound of this noise... It somewhat sounds like when the MacBook Pro reads discs except I have to deal with this noise whenever I turn the computer on.
Please I need to resolve this problem as I don't want to make a 2nd trip back to the Apple store.
THANK YOU! Love you all.

Unfortunately, there is no one here going to cure a hardware issue for you. You will need to get it looked at if it's a fan or mechanical issue, which it sure sounds like.

One of my MacBook Pro's fans is running at full speed

Out of the blue today, my 2011 MacBook Pro started fans went mental when I awoke if from it's sleep. They started running at full speed, far louder than I've ever heard them before. I searched through other discussions and it suggested I try an SMC reset. I performed one of these with no success.
I then opened smcFanControl and noticed that my leftside fan was running at 7000rpm+ and the rightside fan was running at normal speed 2000rpm. It randomly spools on and off high speed and I cannot find any fixes or similar problems online. Can anyone suggest a fix for this or should I be taking it to a repairer?
FYI my logic board was only replaced in April under warranty so could it be faulty?

Hi andyBall_uk
SMC fan control measures temp also. Currently running at 47*C as you can see in the screenshot below. I tried overriding the fan speeds...works for the right fan but not the left one so it appears only the left fan has the fault.
The weird thing is, when you press your finger down anywhere on the left speaker next to the built-in keyboard, the fan slows back down to normal speed, but when you let go it speeds back up again. I might open it up in the morning to see if any of the connections are loose, because it seems weird that this happens with a small amount of pressure applied to the body. Also of you tilt the macbook it sometimes slows back down to normal speed (but sometimes stays at high speed). I will let you know how I go. Thanks for your suggestion/s
