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.

HP Pavillion DV7 notebook PC

I am trying to identify a problem with my HP Pavillion dv7 laptop
Several months ago it started getting hot and showing messages about problems with the internal fan and battery. It would say enter = shutdown and shut off. I suspected a bad battery so I checked it without it just plugging it in with the power cable. It seemed to work better so I assumed that was the problem.
I ordered a new battery and it worked for a while. The problem came back and is getting worse. I can run it without the battery for a while but it gets got and shows the same message.
I read on here that flashing and updating the bios worked for some but the latest update gives me an error IHISI not support BIOS then Insyde flash not supported.
any help would be great this PC has a lot of info on it and I dont think it is a lost cause

The internal fan on my Mac Mini runs continually. It's two and a half years old and there's plenty of ventlation. Problem just started. Any thoughts. Thanks
Welcome To Apple Discussions!
At 2 1/2 years old, I assume this to be a G4 mini - one of the first ones?
It isn't that these were susceptible to this problem but the possible causes are somewhat different to the later Intel models.
First thing to do is ensure it's not a control problem. If it is a G4 mini, perform a PMU reset.
To reset the PMU
- Unplug all cables from the computer, including the power cord.
- Wait 10 seconds.
- Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
- Let go of the power button.
- Press the power button once more to start up your Mac mini.
If that doesn't resolve this, firstly ensure it is not being caused by some errant process or application running and holding the CPU load unusually high. Run Activity Monitor (in Applications>Utilities) and check that the system is basically idle, even when the fan remains spinning. Also monitor the system and see if it takes longer for the fan to spin up to full speed from a cold start (after being powered down for a few hours or so) as opposed to a warm start, rebooting after a period of use.
If the fan runs when the system is shown to be idle and the time it takes to start running fast is longer from a cold start than a warm one, then it is possible you have a hardware issue. This might be nothing more than a loose CPU heatsink or rather more significant, such as the thermal pad on the base of the unit, (it is sandwiched between the underside of the logic board and the mini's baseplate and is used to wick heat away) suffering degradation. Either of these issues can be resolved by an approved service agent, but the thermal pad requires a complete disassembly and the pad replacing, while the CPU heatsink is a relatively easy matter. -
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. -
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

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 appreciatedIn 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.

Hello. I have an iBook G4 (1.07 GHz, 512 MB RAM, 12.1 In.) without the black screen and high speed fan issue.
Sometimes, I feel my iBook get hot and I don't feel the fans turn on very much. I do not know why it is doing it for some reason.
Is there any way or tips for the iBook G4 fan?For the iBook G4 to run a little cooler, you may choose to increase the
installed chip RAM by adding more capacity to the user-upgrade slot...
This should allow the computer to rely less on Virtual memory, where
the hard disk drive is used for swap, temporary and other read-write
files that otherwise may have been handled in RAM primarily.
Since Virtual Memory is essentially the computer writing and reading
files to the hard disk drive, this also means that hard drive is working
harder more of the time; it also means it needs to have a significant
amount of free or unused capacity.
So to add 1 - PC-2100 DDR266 200-pin SO-DIMM (PC-2700 supported
however it will run at only 266 MHz; not the 333MHz on the chip) This
may or may not be near whatever is already installed. Depending on
the build model iBook G4, it may have as little as 128MB soldered on
the logic board and the upgrade slot under the keyboard holds more.
The largest capacity chip is 1024MB or 1GB, so that's best.
You could take a look into a guide such as this, to see how complex the
insides of these portable models are. Tedious with great attention to all
fine details is a minimum requirement, experience and skill is helpful.
The Fan may be only part of the issue, dusty stuff may block air-flow.
•iBook G4 Repair Guide - iFixit:
https://www.ifixit.com/Device/iBook_G4
If the hard disk drive is getting full of stored content (user created) then
it's time to save the content to an external hard disk drive (FW enclosed)
since USB1.0 is rather slow data speed. Also a FW (firewire) enclosed
hard disk drive, with its own power supply can be handy. The ones with
an Oxford-type chipset allow the ability to boot the PPC G4 from a Clone.
A fully bootable copy of the installed computer's OS X, from the external.
This can be an ultimate backup, since it can run the Mac when the internal
hard disk drive fails. These are such a chore to get into for repairs, many
people either try a DIY or find a shop that still works on them, if there is an
attachment to the iBook series. Otherwise, a newer vintage intel based
MacBook (circa 2006 to 2010) may be a value, if not trashed or worn.
Anyway, the need for Virtual Memory (hard drive usage) can generate heat.
Actual installed chip-RAM can reduce that heat generation. A dusty fan or
other issues (worn hard disk drive) can also cause heat issues. A slower
Mac may be due to these kinds of issues as well.
Some sources of parts or service may include wegenermedia.com or
other places at a distance, experts who specialize in compact portable
Apple computers can do a fair job. Many could have inventory of fixed
models in their stock of limited items. OWC sometimes has newer ones.
The iFixit.com site has some repair guides that may cover Apple portables
this old, I have not checked lately; however these are not easy to get into
and sometimes the wires, screws, solder joints and other bits can fail after
an attempt to clean or upgrade the interior components.
At any rate, keep an eye on early model Intel-based MacBooks with an OS X
of about Snow Leopard 10.6.8, as these are a fairly good series. Yet be care-
ful of worn or beat models that have evidence of abuse. You can get these in
repaired condition usually for under $400. or so, with a guaranty. For that kind
of upgrade, keep in mind they use a different kind of RAM and are not PPC.
Good luck & happy computing!

Internal Fans running at maintained speed over 5,000 RPM
My MBP is about 3 months old. Both the left and right internal fans are running at between 4,900 and 5,400 RPM continuously. I am not running any heavy programs, only iTunes and Firefox. Installed the iStat widget which shows all temperature readings below 46degrees. Some posts here have said the fans might need to be replaced. Any suggestions on how to fix this would be appreciated. Id prefer not to have to take my MBP to apple and have it shipped off for repairs for 3 weeks.
Thanks.46 C = 114 F? Yah, that is hot. Under Applications > Utilities > Activity Monitor > CPU, does any process show signs of thrashing (esp FireFox)? I use FireFox, like it a lot (esp under View > AdBlockPlus > Blockable Items, I can filter urls that bring my 3G cell-phone internet connection to its knees) and right now I show 21.1 % CPU for FireFox. and minimal Disk Activity. I do heat up occasionally, and hear my fans spin up ... at which time I turn on the NotePal laptop stand USB fan, since I mainly use the MBP in clamshell mode and with the external monitor. I also use Fan Control (donationware, from MacUpdate.com) and set fans to rock a bit quicker, so I don't lag the rise in temp? Please check these items out and post back. With the Fan Control utility at least you should know if the fans are trying. I've tried all the other Utilities and like Fan Control best ... The MBP does run warm when it is thrashing, so make sure you are all updated, esp FireFox. Maybe try quitting FireFox for a day, use Safari, see if that isolates something? FireFox can be tweaked so easily, which is what I had to do to run cooler ... please post back your cpu and disk spex for FireFox. Also it helps to shut down, boot up with command-option-p-r keys depressed, hear the bong chime twice, then release keys. SMC reset doesn't hurt, occasionally; just to clear the air. All software should be updated to current version. iTunes does have issues too (I focused on FireFox, above). iTunes can go on-and-on (looking for the store, holding the entire collection of the worlds' music in abeyance for immediate play, whatever). Try quitting iTunes, or at least looking in Activity Monitor what it is attempting to do on your behalf, unasked ...

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

An Q on an app that controls the internal fan
Hi you all
I was just wondering if there is an app that could control the ibook's internal fan settings so that maybe the computer could run better if the trigger was lowered a little bit??
thanks
ChrisHi All:
I'm a little worried that my ibook might be running hotter than normal and am wondering if anyone knows of any problems that have occurred from ibooks overheating.
Apple says the operating temps are between 50-95 degrees F. Mine is running, consistently, between 90 and 120F. Usually I use either a stand on my lap or bed, or on a desk/table (with and w/o the stand). I have not been looking at this extensively, mostly I'm just wondering if people have heard of ibooks overheating to such an extent that it causes physical and/or operating problems.
thanks.
oh, and how do I know when the fan has kicked on?
d -
I know there are already some posts about this, but I still cannot seem to solve the problem. Yesterday I updated to 10.4.10, and now my fan is running -very- loud. I have tried resetting the SMU 3 times, I have tried a Fan Control program, I have tried simply cleaning the fans and nothing has worked. When my computer first turns on, it is as quiet as it has always been, just a very soft whisper, however within about 2 minutes the fan slowly gets louder and louder and never shuts off. Does anyone have any advice for what I can do before I box it up and take it to an Apple Store?
Edit: It is the circular fan located just above the power cord that is causing the noise, I do not know if there is another internal fan which may cause this.
Message was edited by: Cassandra BWelcome to Discussions Cassandra - You have not indicated which model iMac you have (how to identify your iMac), perhaps you are covered under Apple's Repair extension programs. In any case, you should have your machine looked at, your power supply is not acting normally.
Let us know how you make out, -
computer got unplugged one day and when attempted to re-boot the power button was jammed. Let sit for a few hours and tried again to turn on. With some wiggling we got the computer to turn on but the internal fan is running on high and will not quit. After a few hours of the fan running (so we would know that the computer was not hot) we shut it down thinking maybe re-booting it would help. We left the office with the computer shut off and the next morning we came in a started it up and the fan is still running on high. We know the computer is not hot and since the noise is very annoying we would love to know how to make it stop. Any suggestions would be lovely.
Not exactly sure why this is in the Remote Desktop community, but try this:
Unplug the computer.
Wait a few seconds.
Press the power button in for about 5 seconds then release it.
Wait a few seconds.
Plug the computer back in and then start it up
I think they call this resetting the SMC. -
AirPort Extreme constant amber blinking light no green since initial start up. Utility says it may be overheating but unit has good ventilation and even after sitting all night still the same. Did notice when first setting up heard internal fan come on periodically and since then have not heard it come on once. Could the fan be bad and this is why it is saying its hot?
Possibly. Have Apple evaluate it.

How to check the speeds of internal fans
Hello. Concerning the defective logic board that causes fans to run fast, some people have implied that there are applications that allow you to check the RPMs of internal fans. I searched MacUpdate and VersionTracker with no vail. Does anyone know of any such application?
Thanks.The mentioned aps are very good. But if you just want a quick check of the fan speeds, open a terminal window and type the following command:
ioreg -w 0 -n IOHWControl|grep "target-value\|location"
The output is the following:
| | | | "location" = "System Fan"
| | | | "target-value" = 1700
| | | | "location" = "CPU fan"
| | | | "target-value" = 1500
| | | "location" = "Hard Drive"
| | | "target-value" = 2300
| | | "location" = "sysclk slew"
| | | "target-value" = 0

PS - those are the normal fan speeds for my 20-inch ALS
