Cooling fan runs too much

I've had my MacBook for about 5 months. Recently (the past month or so) I've noticed the cooling fan running a a lot. Even if it's in a cool environment, sitting on a desktop, it will sometimes run constantly. There are only a couple of applications open and no CD/DVD in the drive. This problem is random; for instance, today it started after I restarted my machine. It's been running non-stop for a half hour now. I do regular updates, including the latest firmware update last week. Any ideas?

I'm not surprised. Last time mine did it is was a printjob that was running. I didn't try to print but something I looked at or did caused it to start.
Go back into activity monitor and high light the process. Then click the stop sign looking icon to quit that process.

Fan runs too much i think and memory issue

hi.,I have a gateway gt4016, amd athlon (tm) 64 processor, 3700+ 2.21 GHZ,896 mg of ram
My fan seems to run very often even when its in sleep mode. Also it gets very sluggish at times. i don't have anything running in background, i don't think and when i try to download a video to attach to email it takes forever. Do you know if more memory would help any of this or make things go faster and not sluggish. i have dsl with comcast.

Hi there I have the exact same computer as you do. I have it maxxed out on memory (4GB) and I have upgraded the graphics card. Mine ran fine new and after I added the graphics card I noticed the fan ran alot more. I think that is because the graphics card generates alot more heat. When I added the memory everything was much quicker but the fans were the same. It will speed up as you put more demand on the machine. So if you are playing games or doing anything graphic intensive it will cause the fans to speed up. Be sure to have the insides blown out at least once a year and if you have pets at least twice a year. You see dust and pet fur will get inside and settle on components causing them to run hotter and thus the cooling fans will come on alot more to try to keep things cool. Also the fan on the back side up near the top will collect dust and hair, so you need to clean it off once in a while. Mine has been a good machine and never failed as far as hardware goes. Hope this helps you out. Post back and let me know what you find out.

Cooling fan runs constantly on Tecra A3

I have a Tecra A3 an my fans runs constantly, even when idleing, and it has done this since i got it (about 18 months ago). It also runs at a constant rate, and it's just like hear Arnold talk - very annoying. Sometimes one (?) of the fans stopp running for just a couple a seconds, and then it starts again, back to the same speed. I've had the computer in for repairs, and they changed the fan and cleand the cooling system, but this didn't make things better, well, okay, I got rid of the ratteling sound, but that was all!
I've tried everything i can think of, currently I'm running the computer fixed on the lowest setting for the processor speed and battery optimized cooling by the help of the Power Saver utility, but it doesn't seem to help at all. I also tried setting the processor speed to low in the BIOS setup, this made some difference, and the fan stayed of for periods of up to 30 seconds (!), bur the performance of the computers performance was horrible with these settings so I had to change it back to dynamic processor speed.
As for the the temeratures i get at temperature of about 36-37 degrees celsius (95-97 degrees Fahrenheit) for the HD temperature (using speedfan). So theres no problems with overheating (?). This leads me to believe that this might be due to a bug in the software. I'm currently using a norwegian install of Windows XP with SP2, it's a custom install, provided by my university (my computer is a student PC bought through the university).
So, can anyone help my make my computer quiet, like normal, sane computers ?!
Thanks in advance for any help!

Hello Stigs
I use Tecra notebook (M1) for years and I can tell you that this model is really one of quietest notebooks I know but it is definitely no utterly quiet and cooling fan runs almost constantly but on slowest level. I know that it has nothing with your problem but I just want to say that quietest notebook produces noises.
Reading your posting I can just say that you are probably right when you say that it can not be because of hardware because the notebook temperature is OK and there is no sign of overheating. The fact is that all newer notebooks are louder than some old models and Tecra A3 is one of them and unfortunately there is no much to do. As far as I know nobody has reported about any software bug till now. Many bugs are fixed by BIOS updates and all I can recommend you, is to check if new BIOS version is available and see if this can help. Please before you start with BIOS update read carefully Instructions how to do this.
Good luck!

Satellite C55-A - after BIOS update cooling fan runs faster

Hello,
I was informed by Toshiba application that new BIOS version is available I confirmed it and BIOS was updated. Now I have problem. Cooling fan runs faster than before and it is very annoying.
Can I find older BIOS version somewhere and roll it back? I don't need it if it doesn't work properly.
Now I have version 1.40. Is there some solution for this new version?
Message was edited: posting has been translated

Toshiba EU driver page provides only the latest BIOS version.
Furthermore the BIOS downgrade isnt possible using the win-bases BIOS update.
In order to downgrade the BIOS on Toshiba unit, you will need to use the traditional BIOS update method which requires special BIOS version. This is available only for authorized service provider.
At the other hand there must be an serious reason why the cooling module run faster.
Maybe the cooling method has been improved in new BIOS just to ensure that internal parts would be cooled down properly.
Its just an assumption but I think it makes sense
By the way: after each BIOS update, you should load the BIOS default settings and should save the changes. If you havent done this in the past, do it

Fans running too fast on MBP Core II Duo

Hi there,
I'm starting a new post 'cause the older one was getting unfruitful. Let me wrap up quickly. I've got both a MBP Core Duo and a MBP Core II Duo. I had notice that the fans on my MBP Core II Duo were very noisy compared to the MBP Core Duo. So I ran smcFanControl (NO I HAVEN'T CHANGED THE SETTINGS AND NO smcFanControl ISN'T BAD FOR YOUR COMPUTER), I just used it for MONITORING PURPOSES. Ok.
I've capture both results in movies so you can see the differences. I've used a cloned system and compiled some code to give the cpu some meat. Here are some behaviors I've noticed:
http://web.mac.com/michaf/iWeb/MacBook%20Pro%20Fans/MacBook%20Pro%20Fans.html
(Just run both movies at the same time)
1) The MBP Core II Duo runs at a minimum of 2000 rpm vs 1000 for the MBP Core Duo
2) The MBO Core II Duo shoots very quickly and hangs it's fans much higher.
3) After a while the MBP Core II Duo has a temp of around 68 with fans running at 4500! The Core Duo instead at a similar temp is down to 2300!
I'm recording with my machines and it's barely usable with the fans.
Has anyone noticed the same thing or is it my machine?
Micha

The movies in your link don't appear to be working so can't comment on those.
Your post confirms what I suspect is true about C2D temps compared to CD temps, which is that the C2D is fundamentally no cooler (possibly hotter) than the CD, but Apple have doubled the fan speed in the C2D to make the C2D run cooler.
Seems to me that Apple bent over backwards to make the CD quiet, and this resulted in them running too hot, and with the C2D they have swung the other way.
I am using Fan Control 1.1 on my CD to steer a middle course. I have left it with 1000 rpm min but set it to start ramping the fan speed earlier and more steeply as temp rises. So most of the time it is quiet, and high temps which can be reached with the Apple settings are avoided.
Doesn't help your C2D problem much except to suggest that you use Fan Control 1.1 to devise settings to suit your purposes. I suggest you have Hardware Monitor on continuously (hidden) so that you see what has happened to the temp over typical working sessions using different settings in Fan Control. When you have found what works you don't need to keep Hardware Monitor active.
C2D can't need 2000 rpm the whole time!

Mac Book Pro Core 2 Duo Cooling Fans running at 6000rpm

Hey everybody.
Need a little help/advice. I bought a MBP 17" C2D back in June and now the cooling fans turn up to around 6000 rpm minutes after turning on my notebook. I've tried SMC fan control, which didn't work. I searched for a stray program, but nothing turned up. I am trying to avoid having to drive to the Apple Store (I will if I have to), but wanted to see if anybody else had a suggestion. Any feedback is appreciated, bigtime. Everything works normally too, all my programs, my wireless card, etc. Leopard installed in a breeze. Thanks in advance for the feedback.

Two possibilities:
1. a stray process is maxxing out your CPUs, and the fans are running normally to keep the heat down. To diagnose this (A) open /Application/Utilities/Activity Monitor, choose "All Processes" from the popup menu, then click the CPU column to sort by CPU amount. Look for anything that consistently uses over 30% CPU.
2. If you've been messing with SMC fan control, it's possible your fans are out of whack. To fix this: (A) make sure you uninstall all fan control software -- there are at least 2 different programs out there, so make sure you uninsall all of them. (B) reset your SMC chip as per: http://docs.info.apple.com/article.html?artnum=303319 (C) when you reboot, if your fans are now quiet, make sure you actually feel the macbook's case -- in one case I had, the fans stopped working which was nice & quiet, but it quickly became blazing hot which was not good.

Satellite R830-182 - cooling fan runs permanently

Hi,
I have just purchased a R830-182. The fans runs 100% of the time, starting with the moment I boot up. Is this right, I expect the fan on a laptop to kick in when the CPU reaches a certain temperature? This is annoying as it is fairly noisy. Have also tried running the laptop at lowest possible power - no software open, WIFI off, battery saver power management, screen brightness turned down etc to no avail.
Anyone out there with the same model know if this is an issue or just how this laptop it is supposed to work?

I agree with as***: change the cooling mode in Win 7 power management
+How to handle the power managment features of Windows 7+
http://aps2.toshiba-tro.de/kb0/HTD12017W0001R01.htm
it seems that your notebook has not been equipped with an fingerprint. But check if the fingerprint software is installed. If its installed, then remove this from the system.
Furthermore I recommend changing some BIOS settings:
+Power Management:+
Dynamic CPU frequency mode (not sure about the available options but try different posibilites)

Satellite L850-1KG - cooling fan runs constantly

Hello
I have the problem that constantly runs in my Nootebook the fan. How can I open the case and clean it?
I have a Satellite L850-1KG
Thank you

I don't know how old is your notebook and if dust can be reason for permanently running cooling fan but try please at first to check advanced power options. There you will find option for cooling method. Set it please to battery optimized. This should reduce cooling fan activity.
I also hope you use notebook on the desk and cooling fan/cooling grill is free.
By the way: do you use original Toshiba recovery image with original display driver?

Mac fan running too loud after update

I have a Macbook pro 13". (mid 2012)
Memory: 4 GB 1600 MHz DDR3
Processor: 2.5 GHz Intel Core i5
Storage: 500 gb
After updating to Yosemite 10.10, my macbook pro's fan is running too loud and producing a lot of heat. I reseted the SMC several times but it didn't help. Surprisingly, The fan also runs loud even if only 1 application is open.
Please advice me what should I do.
Thank you in advance!

I have the same model and I've had the same problem for a few days. I didn't really have problems with heat, but my fan was going crazy even though I was just browsing the Internet. Maybe you're logged into iCloud and have some activity going on. What worked for me was going to:
1. System Preferences
2 iCloud
3. Uncheck things like "Keychain", "Find my Mac", etc. (things you don't need/use)
For me, I unchecked everything and logged out of iCloud. After several minutes, my fan is super quiet and not acting up! Hope this helps.

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:

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.

Lenovo cooling fan is too loud

Hi,
I install fedora linux on lenovo y570 (version with i7) because I buy lenovo without Operating System.
When I'm start fedora few minutes latter cooling fan is start and works continuously, my CPU temperature is OK (~45C).
What I can do with this cooling fan, noise is to big
Thanks

Hi, I put also ubuntu on my notebook, but...
It's looks my laptop in not supported
I always have message "Unable to connect to ThinkPad Fan Control daemon (tpfand). Please make sure you are running this program on a supported IBM/Lenovo ThinkPad, a recent thinkpad_acpi module is loaded with fan_control=1 and tpfand has been started."
I read on wiki page from your link:
Does this work with my Thinkpad XYZ?
This depends on whether your Thinkpad is supported by the thinkpad_acpi kernel module. Check if the thinkpad_acpi module is loaded at all
lsmod | grep thinkpad_acpi
and if not, try to load it by hand
sudo modprobe thinkpad_acpi
If that fails, tpfand will not work with your Thinkpad.
Second command fails on my system, so I definitely can not use this software ;(

Fans running too fast-6K rpm

I noticed the fans running fast a couple days ago. There does not seem to be a reason of this—temps are low (I think): nothing is reading higher than 46°.
What might be causing this? What should I do about it? Is there a danger aside from burning out the fans?

There are a couple of other things to try:
Open Activity Monitor and see if you have an out of control process. Select "All Processes" at the top and CPU in the bottom bar. Look for something hogging the CPU. Sometimes a printer process will hang up and do this, but it could be almost anything.
Run the extended version of the Apple Hardware Test. It may be that a thermal sensor has failed or become unplugged, and if so, the fans are set to run all out by default.
Burning out the fans is the first danger. Burning out your computer because the fans aren't cooling it is the next danger.
Good luck!

Are my fans running too fast?

Hello,
recently I got my rMBP; the basic specs, I am really happy with it, no displays issues or any wierd sounds, but when my Mac gets a bit higher load (e.g. playing Trine 2, my MBP gets around 60 degrees celsius at CPU and 65 at GPU) the fans run at around 5000 rpm, while the left fan is alway faster by about 300 rotates. Hands down, the sound is ok, but I am worried about the speed, is it normal to get such high rates? At minimal load, it is about 1900 rpm so you can't hear it all.
Thanks for all your answers

I've seen fan speeds close to 6000rpm reported here, so I wouldn't worry. The computer is doing what it is supposed to do: increase the fan speeds as needed to keep it cool. Enjoy your new computer.

Cooling Fan runs constantly

Is anyone else experiencing fan issues? I have a mid-2011 MacBook Air 13" (4gb RAM, 128mb SDD). Problem is that the cooing fan runs non stop...and it's LOUD. I run it on a stand, lid closed attached to a 27inch LG Display. Anyone else seen this?

The computer's fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated.
