Macbook Fan Hack - force it on

hey guys,
just wondering if anyone knows a way to hack the macbook fans to manually turn them on. i just updated to 10.4.7 but the heat is still driving me nuts. and the fans don't seem to turn on as regularly as i would like.
thanks!
Ronny

What about a firmware update that enables the fans to come on sooner
Apple has made updates firmware or OS updates that seem to effect when fans come on. Its a tricky balancing act, turn the fans on earlier or faster and battery life suffers. Don't have them come on sooner and heat increases
What temp do the fans come on at? 80 C?
I think for my MB they start coming on in the mid to low 70s, and if the temps reach the mid 80s they ramp up full bore.

My Macbook was hacked by somebody right after activating downloaded VLC player.
I couldn’t control my machine. Every thing was messed up! Finally after reboot I realized that even my administration password was changed. Stupid hint I was able to reed: What located in box above low case ? I used my friends computer and founded hot to fix my problem using Unix commands to reboot in a single user mode. I founded a lot of different solutions which had prity the same beginnings but very complicated continuation, which, I understood will force me to cach during restoration anuther crap – time bomb in my mac! Finaly I did restor. somehow. But still feel somebodyies presents. Safary messed up – I will send you a log Itunes – messed up. Speaker in a top menu – grayed, and I can’t control my volume. But the most triky thing – bouth my Apple keybords – internal and mostly bluetouth external also working and typing wired! I am sorry for my spelling, because I cant check spell for Mac’s Word (in Microsoft it was F7) I have also several attacks from my neighbors by community I know their names, because they are somethere very close to me – I can see them throuth FI-FI connection. They often kick-me out from my place and started to use my resaurces. And also Mackeeper make me a hard time!
In Microsoft times u just reinstalled computer – clean installetion from corporate licensed disk. But now I am a beginner in MAC – I love it! But a lot of new and triky – at this way
Fore example – my goal – to do fool Macbook backup at external USB drive using boot srartup option and make my life yaser in case of crash. But now, I don’t know if I can trust recommended program Carbon copy cloner – Ms. Bombich?
I am very sorry for my spelling, because I feel somebodies presents, who playin with me.
Final question Do I need some antivirus Mac compatable which is update paches, service packs? How to map defolt documents folder not to a local, but to external USB?
Esquse me for a lot of questions, but I am beginner in MAC, and I LOVE it!
PS. Good news. Looks like Safari came back! Somebody, probably allredy helping!
But my interface qute different from original – so something still wrong!

Help!!! Macbook fan not turning on!

Hello there!
I have a problem with my macbook fans. The fans do not turn on until the computer has been running at 80°C for 5 minutes and only then my macbook only runs at 3000 revolutions. The fans idle is 2000... I know this because I have an application from the mac app store called temp. guage and that tells me temperatures and fan speeds.
The fans to both of my brothers macbooks turn on once the computer is about 60-75°C and it turns onto 6000 revolutions and their idle is 2000 revolutions . Could it be that I have a macbook and not a macbook pro? Or could there be something wrong with my fans?
When I got the computer about 1 year ago the fans turned on a lot but I didn't have this app for various reasons but I could hear the fan turning on. I know that the fan back then was faster becaue i could heat it and when the fans now are at 3000 I can not hear it.
Could a connection be loose - I have never opened the back case but I carry the macbook a lot with my in school? Could there be so much dust on the fan that it tries to spin faster but it simply can't? Could it be the grease on the fan? can anyone help me narrow my decision? Do I need to replace my fan?
Today I was at the apple store and I did a diagnostic test. The only problem was with my speakers but I did not notice that. Point it the fans were all right in the diagnostic test but in reality the fans are not all right...
Someone please help! This is a desperate problem my computer keeps on shutting off because it gets too hot.

Thanks in advance!

First thing I would try is resetting the machine SMC.

How my macbooks fan works.

This is how much macbook fan works.
http://mb.neom.ca/fan.mov
I started the recording when it was mooing, and then I ran a process to max out the cpu and heat it up. As you can hear, the hotter it gets, the harder the fan spins. Once I turn off the process (you will hear a beep on the movie when the process is terminated), you can hear the fan start to spin down. About 30 seconds after the movie was done, the macbook resumed mooing, and is still mooing as I type this.
It's an interesting look at how the macbook heat management is telling the fan to work.
My macbook is a week 24 built.

MacBook fan running high most of the time after HDD/Hard-drive Upgrade

Hi guys,
I've just recently upgraded my MacBook white's (MacBook5,2, 2GHZ duo core, 4GB ram) stock harddrive to a WD 2.5" black 750GB. After which, I noticed my macbook fan running at high speeds majority of the time... Even when just doing light weight stuff on it, such as surfing the net using Safari or even just leaving my computer idle after startup.
I did a clean install twice, the second was too see if it was really just a badly installed OS, but the problem still persisted, well at least till I decided to come here to type the post =P (maybe my macbook's scared about being talked about). Do note, that I did a pc migration each time.
After the upgrade, My fan usually runs at about 5000-6200 rpm, but right now as I'm typing this post, its surprisingly alot lower then what I've been experiencing. About 3000rpm-4000rpm.
As for the harddrive temperature, I noticed it runs between the 37 degree to 40 degree celsius range, so I'm guessing the hard-drive temperature sensor isn't busted, which was the problem for others from what I've read from other discussions here.
Also, when I boot my windows partition, the fan doesn't go as crazy, but it eventually will too.
Any idea what the problem could be? =s Or could it be that my MacBook can't handel 7200rpm hard drives =/ If so I'd probably downgrade to a 1TB WD blue =s
On top of that, does any one know if the 2.5" WD blue are as reliable as the 2.5" WD blacks? As I'm heistant to downgrade as I've read that the blues have a higher failure rate, and wouldn't want that happening. Oh and I'm not considering an SSD for this particular MacBook at the moment, as I may upgrade in another two years or so!
Thank you!
Edwin

Hey Mende1,
Well I guess I'll try returning the drive at the end of this week then my fan seemed to have slowed down abit since the upgrade, it's sorta spinning around 3000rpm now. I'm not sure if it's gonna be the same thoughout, and I'm pretty sure it doesn't spin as much as it did when I had my old HDD on. So I'm giving it a few more day probably till the end of this week. And if the noise issue still surfaces I'll try a different hard drive! and update you on the results!
Thanks alot Mende1!
And hello there rauldoppler!
Well, firstly, I'm using a early 2009 MacBook white! The pre-unibody one. It's running on a 2GHz Intel Core 2 Duo processor with 4GB for ram.
As for the hard-drives, I'd actually reccommend you to upgrade to an Solid State Drive if you can afford it, but if you're like me who needs more memory space then boot speed etc, I guess a HDD will be fine =) As for which brand of hard-drives, I would actually recommend WD (their black drives especially, 5 year warranty, 7200rpm speed hehe), but right now I'm having the fan problems, so I'm not too sure anymore.
I did however, do quite abit of digging around on the net and concluded that WD was a better choices amoungst the rest... But yeah the fan issue is still something I didn't expect. All in all, I guess as for which drive is better, it really depends on your needs or wants, if it's for casual internet surfing and stuff, a WD blue HDD would be fine, or a black if you want a slightly faster boot speed etc at the expense of your battery life and all. If you however value blazing fast boot times and application start up times, go for an SSD. If you need the memory space more then anything then I'd say go for a HDD again too, as it's cheaper interms of gigabite to dollar ratio. (for example, the older 500GB version of my new WD black would cost USD $43, while a Samsung 500GB SSD Pro would cost $349) Also, You could do abit of reading up on SSDs if you're interested in it There's alot of plus points to it, like ALOT, and if the price tag wasn't so huge, I would have used it for my macbook already!
Lastly, I used a WD Black 750GB for my macbook upgrade. However, I'm gonna downgrade to a WD blue 1TB this weekend if the fan doesn't settle down over time Cause well, the fan noise is really an issue for me.
Peace out guys!

MacBook fan going off the rails

I've seen some threads on here about MacBook fans failing to spin fast enough, and oddly I have the exact opposite problem. My fan is very normal during typical computer usage, but acts up very loudly and spins quite fast at two times: when I watch videos online, and when I play Diablo 2.
Now I'm guessing the videos make sense, but I play a lot of games on this computer that are more graphically intensive and otherwise demanding than Diablo and the fans aren't half as busy. When I start the game up, a dialog box opens for settings and such before it goes fullscreen and all that stuff starts. Today I left it at this simple little dialog box and watched my fan speed: It jumped from around 1800 to around 6200 rpm in about the span of 45 seconds. I had no other applications open nor was I so much as moving the cursor on the computer. The temp went from 120ºish to 160º F.
It worries me that the fans are working this hard for what seems like no reason. What's more, I usually play the game when I'm plugged in, but a couple of times I've tried on battery power and as soon as the fans get in full swing, the computer just shuts off. This has happened while watching videos online too.
Naturally I'm worried. Any help would be very much appreciated!

Loud fan behavior while watching online videos is normal due to the stress placed on the processor by Adobe Flash.
Regarding Diablo, you are right that it is not a graphically intensive game. However due to the age of the game, I believe it runs in Rosetta, a software translation layer that allows you to run the game on Intel processors. So there is a lot of background software translation going on, and the GPU is used very little or none at all.

Detailed Stat Macbook Fan Question

Dear Apple Community,
After quite some time spent online sifting through threads related to macbook fan noise, overheating, and everything related to it i have finally decided to ask directly for some guidance as i have yet to find a clear solution.
My problem, like many, is that the moment i start using my CPU more than just a few % , temperatures soar out of control and i guess as a result so does my fan.
I have double-triple check alternate causes for this problem. Definately not the printer-que issue as some have posted before.
It is 100% as soon as i go out of idle and use CPU problem starts and noise because problematic when sitting in library.
Here is a quick table on what happens when i go from using just excel to starting and using flash animations/journals/magazines and then back to idle again.

My questions is what i can do to be able to work with normal programs without my mac going crazy? Is it thermal paste problem? Fan seems to work, but maybe i need to open up and either clean with compressed air or replace fan? Other solution?

Loud MacBook fan

My MacBook fan is running at 6200 rpm, 75 degrees almost constantly. In a class yesterday someone asked me to move because my computer was distracting. Please advise!
Even running just one program (FireFox) the fan runs constantly.

hi first time to post here~
my questions goes: the fan of my black macbook has started to "go nuts" for the past few weeks and it never happened before! I checked the fan speed using smcfancontrol and it was always around 6000 (exhaust). at first i thought it got to be the fan control software which messed up my fan and made it run like crazy, but after the uninstallation the problem remained the same. So like some advices here I checked "Activity Monitor" when my fan went crazy again. i found out the latest-updated iTune 8.0 took almost 55% of my CPU-especially whenever I turned on the "Visualizer." as long as I stop using "Visualizer" my fan is back to normal and quiet like a sleeping baby. May I ask is this normal?? Should i take my 4-month-old macbook to apple store for check?

Macbook fan runs continually with Zynga games...

My wife reports that her Macbook fan runs continually when playing Zynga games...internet games in facebook. I watched her, and it's true...if she quits the game the fan stops. Is this a potential problem? Seems that's all she does on that laptop... I suggested she stop playing the games, but that advice will not be heeded:) thx.

Thank YOU for the reply. Wanna nother star? Help me figure this one out:

Macbook Fan Broken?

I think my Macbook fan is broken. It keeps getting hotter and all I keep hearing is the sounds of something loading (like the sound of a CD when it is being loaded in the CD ROM. I downloaded the Mac fan control program to see if that would help. The temperature was at 147 degrees fahrenheit. I put the base speed of the fan at 1800 RPM. The left fan turns on at 500 RPM and then quits after a second. The right fan is at -1 RPM. I set the lower threshold to 104 degrees fahrenheit and the upper threshold to 158 degrees fahrenheit. So far, I have not heard any, even minute, noises coming from the fans. And no air is coming out of the vents.

there is only one fan in a macbook and yeah it sounds broken...bring it to an apple store and check the price to get it fixed...
if you are handy you can change it yourself and check ifixit and ebay...if you are not...backup your data as the end of your laptop is really near...

My Macbook fan just died as well as my computer

My Macbook fan just died as well as my computer starting to shut of after 20 minutes., anyone have heard of this?

You might try to reset the SMC and/or PRAM.

ICal makes my MacBook fan go wild

when starting up iCal my MacBook fan stirres up for a couple of minutes and in Activity Monitor I can see it needs more than 95% CPU. Sometimes also SyncServer kicks in taking also all CPU and even more time.
Is this normal? Or is my ical database corrupted. How can it be that a simple background sync is taking so much CPU?
If this is kinda normal I will switch to Google calendar, to avoid the whining of the MacBook.
Looking forward to your response.

I don't always get the whining fan, but once I launch iCal, I can say goodbye to any free system memory. This has been recurring for at least 2 months, and I've been watching Activity Monitor very carefully, and see an absolute connection with iCal and SyncServer. It's very frustrating, 'cause I really want iCal to work, but not at the expense of my (theoretically powerful MacbookPro w/) System memory (2gb).
At the suggestion of my Apple store's "genius," I exported all my calendars, deleted them from iCal, trashed all iCal cache and metadata folders, plists, etc. I then brought in a few calendars one at a time. I purposely avoided any subscribed ones, and let iCal delete alarms. I ran the computer for a few days with only 3 or 4 calendars, and the behavior was a bit better, but still SyncServer was using LOTS of memory.
My console logs are showing lots of lines with "Invalid address property:" warnings (w/ referenced to eddresses that are valid); and "WARNING: BestCalendarDateFromString - can't interpret:"
So, I'm back to wondering: what can I do!?!?!?
(It is slightly comforting to know that someone else is experiencing similar problems. I only hope someone reads this and has a clue as to what's going on and how to solve it.)

It seams that I downloaded some enfected app I was even not able to trace what url I download as I was not careful before.
After I leave windwos and back to Mountain Lion. I noticed that Launcher took more then usual time.
And when I open my chrom browser it's default search engine was changed to Conduit Search "http://search.conduit.com/Results.aspx?ctid=CT3314958&octid=EB_ORIGINAL_CTID&Sea rchSource=58&CUI=&UM=2&UP=SP6C3AE6B3-DF32-4307-9FB5-8FA6CD32EDF8&q=%s"
Same as windows.
Also some other search engine added in list like
"http://mixidj.delta-search.com/?q=%s&babsrc=SP_ss&mntrId=04A05C5948CD65F0&affID= 123187&tsp=5023"

Please read this whole message before doing anything.
I've tested these instructions only with the Safari web browser. If you use another browser, they may not work as described.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click anywhere in the line of text below on this page to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; echo; sudo defaults read com.apple.loginwindow LoginHook; echo; sudo crontab -l; } 2> /dev/null | open -ef
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
{ launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; echo; crontab -l 2> /dev/null; } | open -ef
Step 4
ls -A /e*/{cr,la,mach}* {,/}Lib*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -ef
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of login items' | open -ef
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

Late 2008, Macbook Fan issues?

Hello,
I am curious to know if anyone has experienced problems with their fan?
I had a power failure at my house, before the failure, the Macbook was running fine as usual, after restarting, Fan continues to run?
Through iStat I can see that the temp is 35 degrees and the dual cpu usage is at little to none? Is this normal, will the fan return to its quiet mode?
Thank you

I'm not sure I understand. The fan always runs continuously. It should idle around 2000 RPM and will increase to 6000 RPM depending upon CPU and GPU activity.
If your fan is running at high speed continuously, then open Activity Monitor in the Utilities folder. Select All Processes from the Processes drop down menu. Click twice on the CPU column to display in descending order. Look for a process consuming a large amount of CPU time. If you find one then select it and click on the Quit icon in the toolbar, then click on the Force Quit button. See if that fixes the problem. Otherwise you may have some file corruption that may have been caused by the power outage. You should try the following in this case:
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU 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 DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger, and 4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

Macbook Fan Issue

MacBook Pro 13 inch Late 2011 2.8ghz intel corei7. 16 GB 1333 MHz DDR3. Intel HD Graphics 3000 512 MB
Running Yosemite...
The fan on my Macbook is running very loud and continuously, even when I close the macbook (as in physically shut the screen).
In looking at the Activity monitor there is a process called launchd which belongs to root which is running at over 70%. (Screen Grab below).
I have tried resetting the SMC but literally nothing happens.
I have tried booting in AHT mode but literally nothing happens.
I can't get an appointment at a genius bar as none are available.
I have to wait a week for a phone call form support.
Can anybody else offer help?

That suggests there is something connected to your Home folder that is causing the problem. The next time it does occur try:
Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
