Macbook pro fan suddenly running more
i've had my macbook pro for about 3.5 years. last year, the battery was replaced. it's been running fine but suddenly i notice the fan running a lot more. first it was when i was using my screen saver which is an aquarium - it used to run silently but now the fan is on when it's running. now the fan is running when i'm playing a simple arcade game on-line. again, it used to play silently but now when i play the fan runs. this is a sudden thing that just started happening. any thoughts? do i need to take it to the shop?
Check Activity Monitor

Reset SMC. http://support.apple.com/kb/HT3964
Choose the method for:
"Resetting SMC on portables with a battery you should not remove on your own".
If this does not help, take the computer to the Apple store.
Best.

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.

My macbook pro is suddenly running very poorly, can I do a system restore?
As of not more than a week ago my MacBook Pro is suddenly locking up, running slow, unable to sync my iPhone with iTunes. I thought my machine may have a virus, so I purchased and intalled Norton AntiVirus, but a system scan came up clean. Whats the problem, how do I fix it?

Macbook Pro Fan Continues Running After download Error -- Please Help so Loud
Hello,
I recently tried to download the Citrix reciever application onto my Macbook pro. The installation was taking an excessive period of time and it was obvious that something had gone wrong in the download because it had taken several hours and was stuck at a certain step. I tried to cancel the installation but it wouldn't allow me. So I force quit the installation and thought that it was shut down, but I was mistaken. The next time I opened my computer the fan was running at an increased rate and was very loud and the computer was heating up. I tried to restart the computer and it said that the program was still trying to download and that the computer could not be shut down until completed. I got frustrated and basically forced a power down by signing out and holding the power button or something of that nature till it shut down. I waited overnight and then powered it back up but nothing had changed and the fan was still running like crazy but it says the program is not trying to install anymore though. I checked the activity level and CPU but nothing is out of ordinary of high. The program is not anywhere on my computer either so I have no idea what is going on and cannot figure out how to stop this fan running like this. It is draining my battery, overheating my computer and is annoying too.
Any help, hints or ideas would be greatly appreciated or I will be forced to visit the apple store for some help I guess.
Thanks,Unfortunately, spoke way to early. The fan issue is still a big problem. From the second the machine is turned on, the fan cranks up. Frankly, I think this is overheating the machine to some extent (running the fan at max speeds when it's not even warm). Additionally, the noise caused by this has only gotten worse, and now it is even making a "whistling sound." Looks like I'm going to be making the trek to the Genious Bar, but based on comments by others on this issue I am not optimistic about a fix.

Macbook pro fan constantly running on high
Hello i have a problem with my macbook pro
as soon as i start my macbook pro early 2011 up the fan goes immediately on high speed and when i look on on istat it says that the fan in going 0rpm but when i push above the F6 and F7 it suddenly stops and the fan goes to 2028rpm i have tried the smc reset and such and that doesn't work at all. I have looked at activity monitor and there was nothing strange as well so please does someone know how to stop this, its really annoying.Most intereseting. The display shows temperatures at very acceptable levels but zero fan speed. That cannot be. Try a Apple Hardware Test:
http://support.apple.com/kb/ht1509
You may have to use the OPTION and D keys to start it.
Lets see if that picks up anything.
Ciao. -
Macbook Pro fan keeps running (2011)
Hi there, I recently charged my 2011 13" Macbook Pro to 100%. Upon using it in class for about 2hours the Fan was constalny running and CPU raging on high. Moreover, the battery goes down to 20% in this time period. For reference, I only had Google Chrome, Mail and Word open in this class period. Whats going on? As I type this to you, the fan is this going strong and my battery in 20%
Any ideas? Should I contact the Apple store as I do have an Apple Care Warranty on the machine
I also have a Curcial 512GB SSD in the machine but this is the first time this is happening in the 3 weeks use in the SSD installed and upadted to Apples latest update a few days ago
ThanksJust to narrow things down a bit.
I had the same problem and discovered the following. When using Firefox, my battery ran out of time faster, my mac was hot and fan ran periodically. When using FF with Silverlight, battery time was even worse, fan almost always on and computer was hot.
On 3rd test, I moved all my open pages from FF to Safari and have been testing the battery time with FF closed and Safari open. So far, my fan has not come on once. Going to watch a video online to see if it's better as well. My diagnostics show Silverlight, by far, is a power hog, FF was the next biggest problem but not bad.
Basic details from rough testing.
6/21/12 with Silverlight running in FF
1.34 min at 12.39 pm full power on screen, full charge
.32 min at 1.39 pm
just over 1 hr.
6/22/12 - activity monitor open, FF, no silverlight.
3.47 min at 9.38 am 3/4 power on screen, full charge, silverlight off and on.
.19 min at 12.28 pm
Almost 3 hrs.
6/21/12 after recharge. Full charge, 3/4 power on screen lighting. All work in Safari, FF closed.
4.39 min at 5.55 pm using safari and not firefox.
3.59 at 7.02 pm
waiting to see.
Hope this helps anyone.

Macbook Pro fans constantly running, Safari hangs up and/or crashes often.
My 2012 Macbook Pro (10.9.2, 2 GHz Intel Core i7, 4 GB Memory) has been acting up a lot lately. The fans are constantly running even if major apps (mail, safari, itunes, messages, etc.) are closed. Safari, in particular, has been hanging up and/or crashing recently for no real apparent reason. My battery has been draining out faster than usual. I've always tried to be very cognizant to the health of my computers and phones and try to limit the amount of apps and files I download, sites I visit, etc. I've already done Verify Disk and Verify Disk Permissions in Disk Utility, reset Safari numerous times, disabled all extensions, removed unnecessary apps, and altered settings in Energy Saver, all to no avail. I'm a grad student so I only use my laptop for Safari and Microsoft Word and put it to sleep when not in use as often as possible. Also, my battery was at 56% about 23 minutes ago and is now at 38%.
Below is a list of the processes using the most memory in Activity Monitor:
kernel_task 429.4 MB
Safari Web Content 127.7 MB
com.apple.IconServicesAgent 122.8 MB
WindowServer 65.6 MB

Any insight would be greatly appreciated!

My MacBook Pro is suddenly running very slow
I am running Lion and updated to the Safari 5.2.1 last month.
About two weeks ago, when I woke up my MBP it started taking about two minutes to locate the WiFi signal (which used to be up and running in a few seconds.) Whatever I try to click on takes a long time to open or come up -- whether I am on Safari and going to other pages or just opening files from my desktop. I get the spinning disk. A lot.
So far I have booted in Safe Mode and repaired permissions and have also re-downloaded Lion. But the problem persists.
I've seen a lot of inquiries about slowness but nothing that specified the hunt for the WiFi signal. Any ideas?Check to see how much Free Disc Space you have...
You need between 15 to 20 GB for your Mac to perform as expected...

Macbook pro fan always running - cpus are pegged by kernel
I reloaded the os with no change. When restarted the fans start and the cpus are pegged within 1 minute.
Did you use the Command-R keys method or did you try Command-option-R keys to boot to true Internet Recovery? You should be able to wipe your hard drive (erasing it and formatting as "Mac OS Extended (Journaled)" with a single GUID partition. DON'T try this method if you don't have a backup as it will erase everything on the hard drive.
You may need to get an external drive and use Time Machine to make a backup and then COMPLETELY wipe the drive and make a COMPLETE new OS installation.
Call back...

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. -
My MacBook Pro fan runs while sleeping
My MacBook Pro fan runs constantly, even while sleeping.
The problem started about 2-3 months ago, but was pretty rare. When I noticed the problem, I would restart the computer and it would stop for 1-2 weeks. More recently it has become more constant, and now it always has the fan running when it's sleeping.
Any ideas on what I should do? Thanks!Mine too. If you're worried you might like to try a laptop cooler like one of these:
http://www.amazon.co.uk/s/ref=sr_kk_2?rh=i%3Aaps%2Ck%3Alaptop+cooling+pad&keywor ds=laptop+cooling+pad&ie=UTF8&qid=1344763538
Not sure how well they'd work on a Macbook as there aren't any vents on the underside but it couldn't hurt and they're quite cheep. -
Mainstage 2.1 makes my Macbook Pro fans run full bore.
Upgraded to V. 2.1 and Snow Leopard. Now my Macbook Pro fan kicks in at full blast whenever I play any patches or run backing tracks. Cpu hit looks low and memory usage is average. This never happened before. Any ideas as to what's happening?
My MBP fans have always run at full capacity when using MS 1, 2 or 2.1. They start out running normally but then start to rev up after a couple of minutes. You could try running some fan control software to manually adjust your fan thresholds but ultimately, does it really matter if the fans are running hard? Seems to me that they're running hard because they need to....MS is still very hard on system resources even if the meters say otherwise. It's the only app I run that causes the fans to run flat-out.

I submitted a question last night but wasn't specific enough-- My MacBook Pro is suddenly making a whirling noise when it's on. Sometimes it's not too loud-- but other times it almost sounds like a tweeting-- there is nothing in the DVD/CD drive-- Is this something I should have looked at?
This is not normal. It is better to have it checked. Take it to the Apple Store.
Best. -
My MacBook Pro will suddenly quit while I'm working on it and restarts itself.
I have a 2012 MacBook Pro running OSX 10.8.2 Mountain Lion with a 27-inch Apple Cinema Display connected to it that I use at work. I am an art director so I am constantly in Adobe Creative Suite 6. In the past month my MacBook Pro has suddenly quit on me while working and restarts itself TWICE. This time I was listening to a downloaded album on iTunes and the music started to skip right before the computer crashed and restarted itself. Has anyone ever experienced this before? It doesn't freeze up or anything like that, it will just unexpectedly go into Restart mode & the computer restarts. Everything is fine once it restarts but I am wondering if I should be concerned or if someone might know of a repair solution I could do on the computer. Should I run Disk Utilites to see if their is an issue? Would appreciate any comments and suggestions and feel free to ask may any question. THANKS!!
