Ibook G4 fan issue

Hi there
I have an ibook G4 14" 933MHz - when I turn it on the cooling fan comes on full speed and keeps running - everything else works fine - any clues whats causing this?
thanks
Troy

i had this issue with a different laptop (sony). when i took it apart, the case was filled with dust, causing the components to run too hot.
what temp is your computer running? after being used for several hours, my ibook cpu temp is at 119 F. i use istatpro to keep tabs on my temps.

Ibook G4 fans?

I assume the ibook G4 has a built in cooling fan, correct? So my question is, how often should the fan be kicking on? I've had my ibook for about 2 months now, and I run off the battery often; as well as , straight AC powerand have never heard them run. I haven't had any over-heating issues (that I'm aware of). Are these fans just ultra quite to where you will not notice them running?

You'll hear the fan if it kicks in. In the iBooks, the fan won't idle--it will only kick in if the CPU/hard drive is warm enough. On my machine (1 GHz G4 from late-2004), the fan doesn't kick in until the hard drive has hit 140 F (at least, I believe it's the hard drive--it's been so long since I heard the fan that I'm not certain anymore!).
If you have the original discs for the computer, you can run the Apple Hardware Test which will spin the fan up to make sure it's working.

Macbook 13" 07 fan issues

So from what i've been reading my fan shouldn't go below 17xx rpms.
the issue is that recently (2-3 weeks) my fan has been making this god awful noise and it goes up or down but never goes away really (unless i turn it off). My fan runs between 18xx - 25xx rpms. can someone tell me how to fix this or if it isn't just my fan. Applecare isn't a possibility anymore it ended about 4months ago. So please any good advice would be appreciated

In my experience, the fan speed will fluctuate (even just a few rpm) ever couple of seconds. If yours seems to be "stuck" at a certain speed for more than a few seconds, then replacing it may be the right thing to do.
Would you be able to record the noise & upload it so I could listen? I'm curious more than anything else!
My iBook's fan also makes a horrendous noise, though it does work. Since that computer is such a beast to teardown, though, and I don't use it very much, I invested in an external cooling pad which prevents the internal fan from kicking in.
Before you replace your fan, though, you should run the Apple Hardware Test and see if it detects any issues. The AHT should be on one of your install discs & the disc will have instructions for how to get the AHT running.
As for the replacement process itself, you can go to ifixit.com to get instructions & replacement parts. The older MacBooks (with a removable battery) are a bit easier to to open up than the newer ones.

MSI GT70 2PC-1044US - HDMI / GPU / FAN issues

MSI GT70 2PC-1044US - HDMI / GPU / FAN issues
I am having trouble with my HDMI port on a brand new MSI GT70 2PC-1044US . Whenever I plug my HDMI cable from my notebook to the TV, after a few minutes (5 - 20 minutes), my fan will start reving at around 5k RPMs and sounds like a jet engine. When this happens, according to MSI Dragon Gaming Center tool/monitor, the GPU temp reading hits 255 degrees Celsius, which is clearly a glitch. I used another monitor, msi afterburner, and when this HDMI problem happens, this tool reads a normal 40 degrees Celsius.
Here are the things I have tried so far but the problem keeps reoccurring:
1. Called MSI tech support, sent me the link to the newest BIOS and updated it
2. Called MSI tech support again, claimed the HDMI is controlled by the intel graphic controller, and they recommended that i update intel drivers (every software tool on my notebook says it's the NVIDIA GPU that controls the HDMI port /shrug???), so i did this as well.
3. Called MSI teck support again, they suggested I send the notebook back to MSI so they could take a look at the hardware. I did not do this because I did not trust the tech guy and did not want to wait a few weeks to get my notebook back
4. Luckily, the store I bought my notebook at was nice enough to replace my notebook for a new one. I got home, tested it, and the same thing happened. So I think we eliminated faulty hardware.
So now what? What else can I try?

have you done EC reset? https://forum-en.msi.com/faq/article/how-to-reset-the-ec-embedded-controller
can you try to plug the HDMI into your dell screen[insteal of sharp TV] to check if the same issue will hapends?
Install latest Intel GPU drivers from: http://www.intel.com/p/en_US/support/detect/graphics
then retest
-Yes, I did the full EC reset. Once the EC flash was done, I removed the power cord from the back and the battery and let it sit for a few minutes before restarting.
- My Dell monitor is old, and does not have an HDMI port, but I will try a different cable on a different TV.
-I already have the most recent intel graphic controller drivers, this one of the things the MSI tech support guys asked me to do by phone

Has the T430 fan issue been fixed?

Hello all,
I am thinking of selling my Macbook Pro and getting a T430, but I am a little concerned with the fan issue being reported here in the forums. Has the problem been fixed in the newer models? Thanks in advance for your reply.

I'm in the same situation, a year ago I purchased a T420 and I was very pleased as the notebook was very quietly most of the time. My notebook was stolen a week ago () and I'm looking for a replacement. As I understand not everybody is suffering this problem of whining fan, have any idea if this problem could be associated to only some particular models??. For example, this problem affects both the models with integrated & dedicated graphics (as far as I understand the dedicated GPU can generate lots of extra heat inside the machine that needs to be dissipated)??
Best Regards
Luis

IBook G4 "Fans of Death"

Hey there guys, just swapped an old iBook G4 of mine since the old one was dead, and since the swap I'll press the power button, black screen, then the fans will run at max, this will go until i disconnect the battery. I've tried reseting the PMU already. I've noticed when I press the power button the power adapter will change colors.

There may be a hardware problem behind this symptom, in some instances it could involve some circuits on the logic board; but there could be other causes, too.
A general dogpile of results came in when I used google search of symptoms: ibook g4 fan running black screen https://www.google.com/#q=ibook+g4+fan+running+black+screen to include questions/replies from elsewhere online. To include a few from Apple support discussion communities.
This Apple communities discussion probably covers most angles of the symptoms...
https://discussions.apple.com/message/18547073#18547073
There are a few authorized repair facilities that offer a fix for solder joints that may be a cause of this problem; in that the hot/cold flexing of solder joints on the logic board had been suggested as a cause of failure in certain instances. In the case of this kind of repair, once opened up and corrected, any additional upgrade or replacement of worn parts is nominal over the cost of the parts.
Hopefully this helps somewhat.
Good luck & happy computing!

G5 Unusual Fan Issue - Need Help

While I have read much about the G5 fan issues, I haven't found anything that matches mine.
This is a 1.8Ghz DP running OS 10.4.9 and it is really noisy due to the 2 drive bay fans running at top speed.
All other fans run properly and respond to the air deflector removal (also checked using iStat Pro)
Apple hardware diagnostics check out fine with everything passing and ambient temperature of the drive area is fine (90 or so degrees)as well.
I understand that the drive temperature sensor controls the speed, but typically the issue has been the other way around. Would unplugging the sensor for testing hurt the logic board? Could the fan be bad? How about the FCU? the other fans seem to work as advertised.
From the sounds of it, the Thermal calibration wouldn't be needed.
Does have anybody any idea of how to correct this or can the FCU be reset? I did reset the PMU several times.
Thanks

Strangely enough, the answer to the problem was that the rpm controls in both the fan and the blower of the media bay were damaged. Power spike?
While they are difficult to come by (they can't be purchased separately as they are part of the enclosure assembly) they are certainly cheaper than a logic board.
Btw, if anyone else has a similar issue, the media blower is the only truly unique part. The media fan is the same as the fan in the speaker/fan assembly which can be easily found.

MBPr Fan issue

Hello,
I bought a macBook Pro Retina and have been experiencing some issues with the fan.I saw a lots of thread talking about fan issues but not sure if a solution has been found.
Problem : I can be just browsing the web or checking emails or playing music through iTunes, and the fans will spin up to full speed for a minute or so, and then return to normal. (low CPU usage et low temperature < 40°c)
Configuration : MBPr mid 2012 - i7 2.3ghz / 8GO Ram / 256GO SSD Samsung.
I have run all updates available for my machine.I ve tried the smc & pram reset.
Is there any solution ? Should I go to an apple store ?
Thanks

Can only help.
You can also run an Apple Hardware test to see if ant problems are discovered. Do not assume that a no-error result is definitive.

Fan issues galore

So (i'm not sure of the name of the fan) the fan that is on the face of the tower with the internal speaker attached to it...went nuts and I could not get it to stop. I was told to change out the PRAM battery. I did that. Still an issue. I was told to do a clean install of leopard. Did it. Still didn't solve the problem. Out of frustration, I unplugged that fan from the motherboard and now my hard drive fan is going nuts. All of my temps are normal, nothing above 50 degrees F. Do I just need a new fan or is there something i'm missing?

I was having fan speed issues and reinstalling the drivers for my graphics card (ATI x1900 and ATI Display utility) and restarting has apparently fixed it. I had noticed my OpenGL graphics weren't running properly and the 'Flurry' screen saver was choppy, as well as issues with DVD playback (error -70017). I was trying to fix those problems and it ended up solving them and the fan issue as well.
So maybe try reinstalling your graphics drivers and rebooting. Might be worth a try. Hope this helps.

Unique fan issue Dv7

Hi everyone !
I have an old Dv7 laptop and I know its known for heating issues but im facing a unique situation. Over the years I have never have any issue , only this week I have noticed it over heats. and on further observation I can see that the fan isnt running most of the time.
However If I tap the laptop's backside with my hand , fan just starts running as it should. I thought its some connection issue and opened it up but coulndt find anything. The fan isnt dirty aswell. Just wont run automatically....
Also on very very rare instances It starts itself aswell.
Is there something I can do myself with it OR just give up and take it to a repair guy ?
Thanks a lot !
Regards

Thank You for the response. Thats the issue really , I can buy a fan and replace it myself now that I know how to get to it but How do I know its really a fan issue ?
I mean it works normally when it finally starts , just wont trigger itself. Could be an issue with the temp sensor which senses the temperature and commands the fan to start ?
Thanks again !
Regards

More Heat/Fan Issues with Tiger--Help

I have followed the heat & fan issues for sometime. However, I finally decided it was time to move from 10.3.9 to 10.4.3.
I upgraded yesterday, first using the upgrade option to move from 10.3.9 to 10.4.0 and then installed the 10.4.3 combo upgrade. I've repaired permissions and rebuilt the disk directory using Disk Warrior. There were no directory errors and only a couple of trivial permissions changes.
However, my Powerbook's fans are running constantly and my CPU heat is always pegged at about 135 degrees F, which is as hot as it ever gets. This happens within about 40 minutes of starting the Powerbook up cold and it stays that way for as long as I'm using it, regardless if there are any apps being used.
Activity Monitor indicates that the launchd process is using from 18% to 20% of my CPU, even with nothing else running. I've disabled all Spotlight indexing and I've turned Dashboard off. It appears that it's the lanchd process that is accounting for the extra heat and fan use. It simply won't drop below the 18% to 20% of CPU. There is no other process that is using any significant amount of my CPU when nothing else is running.
My processor is set at Automatic, the same as when I was using 10.3.9.
I was using Silk, Application Switching Menu (ASM) and Macaroni, but I've uninstalled them. No change.
I've reset the Power Manager (including deleting the com.Apple.PowerManagement.xml file) and reset NVRAM. Again, no change.
Finally, when I boot back into 10.3.9 (on my backup hard drive), the fan activity and heat return to what I consider normal--much lower than with 10.4.3. Specifically, the heat and fan activity is directly related to CPU use. If I'm not doing anything, the heat drops and all the fans go off.
There is one other curious effect of 10.4.3 vs. 10.3.9. When I'm running Firefox (latest version), all Firefox user-interface stuff (menu selections, opening many tabs in succession, etc.) are MUCH more sluggish than when using 10.3.9. Frankly, I was expecting the opposite.
I would really like some help with this. I've read all the troubleshooing info on MacFixit and Macintouch related to heat and fan issues associated with Tiger.
12 1.5Ghz Powerbook Mac OS X (10.3.9)

I'm the originator of this thread and I appear to have an answer.
I tried an "Archive and Install" of Tiger, on top of my existing 10.4.3 install that was giving me the trouble I described above. I had the time today and figured "what the heck[ll]".
I then installed each additional piece (10.4.3 combo update, airport updates, quicktime updates, java updates, etc), stopping after each one to check CPU temperatures and CPU use in Activity Monitor.
I'm now back to a full 10.4.3 install, with all current recommended Apple software and I don't have the heat/CPU use problems I previously had. There is no significant use of the CPU by the launchd process.
I also re-enabled Spotlight indexing and that doesn't cause a problem either.
Also, my entire system is *MUCH* quicker and responsive. I wish I knew what piece in my previous system install was causing the problem, but hopefully my experience can help someone else. When in doubt, do an "Achive and Install" rather than an update to the previous system installation.
By the way, with heavy Spotlight indexing going on and mild web browsing, my CPU temp is just 112 to 115 degrees F. Previously, with no Spotlight indexing and with NO apps running, my CPU temp was maxed at 135 degrees with fans on full. And if you're reading this thread, you know what max fans sound like on a 12" PB.

Strange iBook G3 battery issue

I have an iBook G3 FireWire model which won't recognise its battery. It displays as 5% charged with the "fully charged" icon next to it and the menu saying "Calculating... until full." Unplugging the computer will force it to shut down. The computer's optical drive is broken, so I had to install Tiger via USB. The first time, it worked just fine, charging the battery as normal. The problem arose when I installed some updates (I think it was the 10.4.11 Combo updater) and shut down. Upon restart, it never reached the "Starting Mac OS X" screen, just staying on a light blue screen with a perpetually spinning wheel. After attempting multiple restarts, I unplugged the computer while it was on said screen, and it lost all power just as it does now. I reinstalled Tiger with the same USB and disk image the next day. Both http://reviews.ebay.com/iBook-Clamshell-Battery-Issue?ugid=10000000007193925 and booting into Open Firmware and entering the commands reset-nvram, then set-defaults, then reset-all yield the same result: it will charge to 13%, then stop and say "Calculating... until full." The charger is known to be working, it charges my PowerBook just fine.

The typical lifespan of a lithium-ion battery is two to three years. Some last a little longer; some don't even last that long.
It needs a new battery.
Which exact iBook model is it?
You can choose from this list:
http://www.everymac.com/systems/apple/ibook/index-ibook.html
It would seem that it is recognizing the battery; it's just not charging. If an iBook doesn't recognize the battery, there will be an X through the battery icon in the menu bar and the System Profiler wouldn't give you the battery information; it would say "Battery Installed: No".

Has Apple ever fixed the fan issue that results from upgrading the hard drives on 2009-2010 iMacs?

Has Apple ever fixed the fan issue that results from upgrading the hard drives on 2009-2010 iMacs?
My CPU fan defaults to 3000RPM. I can rev the fan higher with 3rd party Fan controllers, but no lower than 3K.

OR you can short out the original temp sensor, to make the fans rev at quieter speeds.
You can also install an optical temp sensor in place of the old one, it will still read temps and adjust the fans accordingly, just not as good as an internal sensor.
Use something like this:http://www.ebay.com/itm/New-922-9229-Cable-Temp-Sensor-Optical-iMac-27-inch-Late -2009-2010-/111106349896

Internal fan issues

I have noticed that the fan in my macbook makes really loud noise when I turn the computer on, even when its really cool to touch. Also the fan is triggred on when I put it on any surface, when I am typing it turns off and as soon as I stop typing it turns back on. My apple care protection plan has expired, can someone please point out the problem and suggest what I should do to fix it.
Thank you.

I was able to resolve the fan issue. Just had to open the macbook and clean out the accumulated dust. Tedious work but worth it, works as good as new.
Followed these links:

Yet more fan issues

I see that fan issues are a frequent topic, but I haven't read anything quite like this so I thought I'd post just in case someone has any advice:
About a month ago, my iMac (ALS, 1.8 GHz, 1.5 GB RAM, 10.4.4) starting turning its fan on full blast while it was asleep. They run for about 30 seconds to a minute and then turn off on their own. When I subsequently wake it up, the wake up procedure is delayed, but it appears to be okay... for a while. However, when I try to log out our shut down it will get hung up eventually requiring a hard reset.
Notably, although most programs will work fine during the time between wake up and shut down-related crash, Toast Titanium (ver. 6) will not completely launch -- the icon will appear on the dock, but I can't access the application, and I cannot force quit it.
This problem persisted for a few days, and then went away! Even Toast begain to work properly again. It was not clear to me what fixed it: quite a few restarts, permission repair, disk repair, etc, but nothing seemed to be a "magic bullet".
Unfortunately, the problem just started again. That is, the fans started coming on during sleep and the computer will eventually crash. Furthermore, Toast Titanium stopped working at the same time.
Any ideas regarding how the fan issues and Toast are connected?
Thanks in advance!

Check that you don't have a power supply issue:
http://www.apple.com/support/imac/repairextensionprogram/
And even if your serial number does not appear in the link above, run the extended hardware test with the restore disk that came with your machine. The instructions for doing so are similar that of the Powerbook restore disk here:
http://docs.info.apple.com/article.html?artnum=86287
If there is a power supply issue, or a fan issue that is a hardware related problem, it might appear in that test. The lack of a positive may mean something else is wrong, but at least it is a place to test. Is it happening when no third party devices or networking is hooked up?
