Hot & Loud - Left Fan staying at over 6000RPM

For about a week or more now I've notice my MBP being extra loud and extra hot. I did have an issue with an errant app (APC PowerChute) that was maxing out one core. I uninstalled it and it did improve, both fans no longer stayed on and the temp no longer hit past 200f.
However that didn't seem to resolve it completely, the temp will jump up to 175f-190f after only a few minutes of being turned on and nothing but Mail open. That is after it has been shutdown completely all night.
iStat Pro tells me my Right Fan is running at just over 2K RPMs, while the Left Fan is over 6.1K which is very loud. The fans occasionally make odd sounds that make me think at least one of them is dying.
I have reset the SMC which had no effect. Running "top -o cpu" shows only around 20% total CPU usage.
While I cannot confirm the timing of these issues, they did seem to coincide with when I updated to 10.6.3 on release.
I don't know if its related, but I have also noticed that if I leave it on when I go to bed, when wake it the next day it has either restarted, or attempted to (with a dialog on the screen that X application prevented a shutdown). This seems like it would make sense that if the machine got to hot, it would try to shutdown.
Any help or suggestions would be appreciated!

If yours is one of the current 2.53ghz unibody MBPs with non-user removable battery then it only actually has one fan, dwight. (iStat Pro still reports a "right fan" spinning at close to zero revs, but it is a figment of the program's imagination!) The single "left" fan is actually located in the centre of the rear of the computer (no chance that something is blocking the vents there?) .
(If, instead, you have one of the earliest unibody 2.53 MBPs with a *user removable battery* then you can ignore the stuff that follows, as those models do indeed, have two fans, and the fact that one was running and the other was not would certainly be a hardware issue)
The fact that the fan is running at full speed AND the temps are high strongly suggests to me that this is probably an issue related to excessive processor use rather than anything else, but your reported CPU usage is quite low. Could you check this using Activity Monitor following the steps outlined at http://support.apple.com/kb/TS1473 just to be sure that you don't have a "CPU hog" of some kind.
If it was a 'temperature related" shutdown occurring at night no process would be able to prevent it. Such shutdowns involve processes built into the processor itself and aren't over-ridden by the normal software shutdown routines.

Left fan got louder after around 2 months

hey. I just discovered that after around 2 months of use my left fan got louder. Is this normal ? I mean it can be normal if you use a laptop for around 2 years, but it is kind of weird that this happens just after 2 months. seriously my fan was very very quite when i got my macbook pro, but now it seems to become more and more anoying plus the freaking whine...
Regards,
Martin

Hey Martin,
To stop the whine use a program called 'Quietmacbook' Google it and you will find it, this stops the whine by loading the 2 processors but don't use it on battery life otherwise it will reduce your battery time, as for the fan, i have week build 28 on my macbook pro and the left fan is always on after the firmware update to stop the so called mooing issues, its probably the amoutn of dust in there which makes the fan spin faster to push out the hot air

Is it normal for the mac book air to run hot and the fan to be loud

I just bought my daughter a mac book air a couple of months ago and it is now running hot within two minutes of turning on and not doing anything. then the fan is loud running hard to cool it down. it does not stop. left it alone for 20 minutes. still hot and the fan is loud

It's not normal. Read Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity
Power or other problems related to unexpected system sleep, shutdown, lights or fans also call for an SMC reset.
Read and follow the steps.
Before Resetting the SMC
Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
Resetting the SMC on portables with a battery you should not remove on your own
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.

In my macbook pro 15 inch mid 2012 model, my cpu and gpu will get very hot, when gaming or rendering sometimes over 200F. The fans only spin at max about 2900 rpm, when their max is 6400. I downloaded a fan control app, but how can i fix it?

Hi rhaughan,
I see that you have concerns about your operating temperature of your computer while using resource-heavy applications such as gaming applications. I have an article that will address some of the concerns you have mentioned:
Mac notebooks: Operating temperature - Apple Support
http://support.apple.com/en-is/HT201640
While there are third-party utilities that measure the temperature of a notebook computer, it is important to understand that these utilities are not measuring the external case temperature. The actual case temperature is much lower. Never use third-party applications to diagnose possible hardware issues—instead, contact Apple or go to an Apple Retail Store or Apple Authorized Service Provider.
You should also see this article for even further information about your fans:

When I'm streaming videos from my Macbook Air to my AppleTV, my Macbook Air gets rather hot and the fan works hard and is loud trying to keep the laptop cool. Is this harmful to the laptop? Is this normal?

My MBA fans start running when I play video too - the CPU's video processor is working pretty hard to decode the video. The fans job is to provide better airflow. The time to worry is when you play video and the fans don't run.

Late Macbook Pro getting hot and the fan is getting louder

My Macbook is getting very hot and the fan gets louder the longer I have my Macbook on.
It happens whenever and wherever I use it, I don't play games often as I use my Macbook for my Uni work.
Does anyone have any advice?

It would help if you indicated the EXACT model MBP that you have.
Perform a SMC reset:
http://support.apple.com/kb/HT3964
If no success, open Activity Monitor to ALL PROCESSES and set %CPU to display values from high to low.
Download from the Internet a temperature monitoring app like Bresink:
http://www.bresink.com/osx/TemperatureMonitor.html
Post images of both for inspection.
Open the MBP and look for dust an debris inside it, especially in the fans. Clean it out if necessary.
Ciao.

Computer gets very hot and fan stays on

I have a HP with i7 it gets very hot and the an stays on. I think somthing must be running in the back ground but I can"t find it. I have all the cooling tables etc. any ideas any one?

What is your laptop model?
Probably the heatsink clogged with dust and has to be cleaned up.

Left Fan buzzing and ticking!!!!

hello people,
i've had my new macbook pro late 2008 for the past 2 months, and just out of nowhere i started hearing a left fan buzzing and ticking. the sound comes and goes every 5 minutes and stays for a long time, and it also starts as soon as i turn my mac on, then goes off then back on again and so forth and so on. this is really annoying. i am wondering is this normal?? would this get worse and affect my mac in any way?? and most important is there any way i can fix this or get rid of this left fan issue??
thank you in advance for all.

This happened to me too - MBP was perfectly silent for about a month, then the left-hand fan started buzzing, not too loudly, but enough to be audible. I thought it might just "wear itself in", but the noise increased instead of decreasing over time.
I took it in to a repair centre last week, they confirmed the fan was faulty and have ordered a new one, will arrive this week. Hopefully the new one will solve the problem.
Just for information: the new design makes the fans very accessible and easy to replace, so this is not a difficult job, nor is it likely that a technician might damage the computer in another way in order to get at the fans, as might have been the case in other models with more complicated internals.
Also, if you want to risk voiding your warranty, ifixit.com sells replacement parts you can install yourself, including the fans. But I wouldn't suggest this while the computer still has any warranty left - get Apple to repair things for you.

Macbook Retina, Loud Idle Fans, Fans start from downloading files

hello
i have a early 2013 retina 15" macbook pro
is it normal that the fans kick in from browsing in youtube? or when i download 2 big files at the same time.. like 500 MB for example
i think it cant be normal for a computer like this to have spinning fans when usage is so low
also my left fan makes a strange noise sometimes, on the right side you only can hear the spinning air from the fan, but not the fan itself,
on the left side you cleary hear a noise while the macbook is in idle, its not extreme loud, but you can cleary hear the fan fro distance when in idle
is this normal?
i trid everything, smc reset, completly reinstalled 10.8.3 but its still the same
the next apple store is over 1 hour away with my car
so i hope to find some helpful answers here first please
Should you hear the fans from a normal working distance when your maschine is in idle with alost no usage
browsing, downloading files etc..
thanks in advance
deniz

Your computer uses Flash to watch YouTube, and it may make your Mac work harder because it consumes a lot of CPU and memory, so it may be normal. However, it's not normal that fans turn on when you are downloading two files.
I recommend you to run Apple Hardware Test in order to check if there's something wrong with your computer. To do this, connect the computer to the charger, and hold Option (Alt) and D keys while your Mac is starting to start into Apple Hardware Test. Choose the language, mark the option to run an extended test and start the test. When it finishes, if it shows an error, copy it here and get ready to take the computer to an Apple Store. If not, there's a process which is consuming a lot in the computer

Left fans don't work ?

My brand new Macbook Pro 13'', has a problem, I observed that it gets hot very much (i think) however the fans on the left side don't blow air out while the right ones do. Do left fans blow out air ?

denozi wrote:
Do fans take in air from left side and gives out from the right side ?
No. In your case the fan (singular) draws in air from both sides as well as the left rear and blows it out the right rear.
First take a close look at the excellent picture clintonfrombirmingham posted of the inside of your rMBP. Look at the left and right edges and you'll see very fine slots in the case. Air is sucked in there and is drawn over the interior parts by the fan to remove their heat.
Second, recognize that you're looking at the bottom, so, with the Mac right side up, the fan is on your right. The 15" rMBP has both built-in graphics and an NVIDIA GeForce GT graphics coprocessor which requires a second fan on the left side to keep cool. When you lift up the screen, you can see vent openings at the hinge, which the fan is pointed at and which you can also see in the picture.
The fan will respond to heat buildup during use and those vents on each side are very close to the bottom and easy to block unless the rMBP is either on a hard, flat surface or is raised. If all the vents are clear and it's still getting warm, either take it in to Apple, as clintonfrombirmingham says, or try smcFanControl, which you can use to speed up the fan beyond what Apple considers cool-enough. But don't over-do it; too much can wear the fan and suck in extra dust.

Proof: ever running left fan is the harddrive! Post your drives!

Hi!
I know there are some posts around here from users that report that their left fan is always running. I started one of those threads myself. Therefore I also know that there is debate, whether this sound comes from the harddrive or from the left fan spinning slowly.
Yesterday I was in a store because my mbp made all kind of noises but this constant sound that seemed to be rather loud on my book was my major concern (I can hear it from a few meters away in a silent environment in which I work most of the time). The technician tried some hacks to shut off the harddrive, but they seemingly didn't work (he actually concentrated on the whine because it was too loud in the store too hear the "swoosh" and because it also has a very intense mooing and a bent case, it's still doa and will be replaced in the next days).
Anyway, today I suddenly noticed that the noise had stopped. I was extatic. As soon as I clicked on something, the noise would start again though.
So: What did the technician do? He set the disksleep timer to a minute. I thought, it then would spin down for a minute. That's why it didn't seem to work, when I ran the command in terminal again in a quiet environment. So after a minute now, my harddisk would spin down.
So here is how you can test if your drive is the everlasting "swoosh"-producer. Don't do anything of the following if you feel as if you had no idea of what you are doing! I can give you no warranties at all (esp. harddrive-damage. See question below! I think it's best to reimpose your normal energy saving settings afterwards and not let the disk spin down every minute)!!!
- Open a terminal-window (it's in applications->utilities)
- Type sudo pmset -a -g disk and note the "disksleep" settings for battery and ac.
- Type in the following command:
sudo pmset -a disksleep 1
You will then need to enter your administrator password.
This will actually set your disksleep timer to a minute (for battery and ac. If you only want to test this for one of those states, use -b (battery) or -c (charger) instead of -a. This could make it easier to go back to your former settings afterwards, in case your ac and batterysettings differ). It is normally tied to the sleep mode of your mbp in general. That's why it's easy to think it's the fans.
- To check, if it worked, enter:
sudo pmset -a -g disk
The new time should then show up under disksleep for both ac-power and battery.
Then just don't touch the book for a minute. Don't do anything with it. Don't click anywhere. After a minute, the harddrive should spin down, leaving you with complete silence. As soon as you do anything that requires hardware access (even clicking on a scrollbar in a programm that runs from an external disk) you will hear the harddrive spin up.
Changing the disksleep might actually change your energy settings. So after trying this you can reset the disksleep to it's previous status by going into the energy saving preferences and readjusting everything. Use the sudo pmset -a -g disk to check if everything is back to normal. Maybe you need to go into the manager another time so the changes will be made.
My question is: Does it hurt the harddisk to spin up and down often? When I set this to a minute and e.g. write a post here, it will spin down or when I read a webpage, it will spin down until the next click of my mouse. So there isn't so much use for it anyway. But will it damage the harddrive over time when it is spinning down so often?
If you think your mbp is very silent, I'm interested in what harddrive you have. If you think, your mbp is unnervingly loud, please post your harddrive as well. (you can find the info in finder->applications->utilities->system profiler->serial-ata)
Mine is a:
Capacity: 74.53 GB
Model: TOSHIBA MK8032GSX
Version: AS114B

Mine's silent, but then I have a different HD spec from your's.
My question is: Does it hurt the harddisk to spin up

webpage, it will spin down until the next click of my

The HD is a finite par, so increasing its usage above the norm. will probably decrease its life-span of effective use.

in what harddrive you have. If you think, your mbp is
unnervingly loud, please post your harddrive as well.

Left fan spins slower than right fan

Hello there..
This morning suddenly I noticed something peculiar. I have this iStat Fan Sensor running in the menu bar and found out that the Left Fan spins at 236rpm and the Right Fan at 5996 - 6005rpms. Perhaps it used to be 2400 or 3000 rpms in avg. most of the time for both fans in an idle state.
I'm beginning to think something is wrong.
Is it normal or something really going wrong? I have my MBP 2010 15" model serviced back in 2011 and they changed my logic board. Never had any issue about this fan issue since then.
So any idea what is going on?

Just to update....
Well I shutdown my computer and let it rest for 2 hours and then turned it back on this morning and it has been running since this morning and now it seems to be everything ok.
Never did my hardware test nor SMC reset.
So far so good but will wait and see over night and will update.

My new macbook air 10.7.3 is running hot with the fan blowing just by using the internet. Is there something wrong with the computer?

My new macbook air is 10.7.3 s running hot, with the fan blowing after about one hour on the internet. It will also run very hot with the fan blowing when it is closed and in sleep mode, is this normal? My macbook pro did not do this.

My Macbook Pro 15" Early 2008 model had been running hot for a long time.
Checked Activity Monitor. (Applications/Utilities)
AdobeResourceSynchronizer was taking 83% of CPU usage.
Did a google search and found information regarding AdobeResourceSynchronizer causing high CPU usage and heat.
http://forums.adobe.com/thread/822790
Problem seems to be Adobe Resource Synchronizer.app
To disable go to: System Preferences > Accounts
Click the Padlock icon, enter password if needed, click Login Items,
uncheck AdobeResourceSynchronizer
I don't know how this got install on this computer.
I suspect Adobe Reader. AdobeResourceSynchronizer.app is within the Adobe Reader application package.
Control Click (or right click) the Adobe Reader app, click Show Package Contents
Location: Applications/Adobe Reader.app/Contents/Support/AdobeResourceSynchronizer.app
Some other Adobe applications may also cause this to run.
After disabling this in System Preferences > Accounts, temperature seems to be acceptable.
Also start Adobe Reader X, go to Preferences, Tracker and in the "Automatically Check for New Comments and Form Data", slide the top slider all the way to the right so is says Never.
After having done all this and restarted the computer, check Activity Monitor again and see if
AdobeResourceSynchronizer is still running. If it is you can click on it so it is highlighted and click the Quit button in the upper left.
This solved my excess heat problem.

After taking a dip in my vest pocket in the washing machine for about 10 minutes, my nearly new 5S spent 5 days in rice and silica gel packets. It definitely dried out, but there is damage to either the battery or the circuit board because it turns on, and I continuously get a blue screen and it reboots every five minutes for a half hour, and then miraculously, it stays on and works perfectly. But I wound up having to fork over $700 for a new 6+. because I couldn't stand the rebooting any longer. I had no insurance, but I do now, Apple insurance, not carrier ins.

Macbook Pro - Left Fan

Hello.
So I got my brand new macbook pro 15inch on wednesday. and today, I noticed that the left fan is making a soft 'ticking' noise. I have not hit the mac or damaged it in any way. (Treated it like a new born baby)
So I did the live chat and the woman told me to reset the SMC (which I did) and reset the PRAM (which I also did). I can only hear the buzzing when I put my ear to the left side of the mac. Nothing wrong with the right. Also: When the fans turn up, I can hear the buzz a bit louder. (again when I put my ear next to it).
Oh and finally: I can hear a sort of high frequency sound from the left.
Help?
