Problem with my macbookpro's fans.

Ok so the problems is that the fans are running like at 6000 rpm all the time since i installed leopard, does someone else is having this same issue? It doesnt matter what program i am running at the time, i could be itunes and just firefox and the fans will be alwys running at 6000 rpm.
i hope someone can help me ,thnks

dmingos is partially correct.
the steps he/she provided are for resetting the SMC (not the pram)
http://docs.info.apple.com/article.html?artnum=303319
to reset your pram:

In your situation, I would do both.
I would also open your activity monitor (applications > utilities > activity monitor)
across the top, click on the All Processes tab
click on the CPU column, to sort by CPU load.
Is there any app that is hogging your CPU?

Airplay problem with 2012 MacbookPro w/ Mountain Lion

I have a 2012 MacbookPro that I recently purchased. I also just bought the AppleTV 3. I upgraded to the Mountain Lion last week and initially the airplay icon showed up in the menu bar, as well as the display in system preferences and I was able to mirror my MacbookPro perfectly. Now, my MacbookPro is not recognizing the AppleTV. The Airplay option in the menu bar and the display is gone. My MacbookPro and AppleTV are connected to the same Wifi and they have both been restarted and updated to the newest software! Why is my MacbookPro not giving me the Airplay option?! Please help!

Same problem when reseted the PRAM.
I read some Chinese Web , Many people got the same problem after upgrade to mountain lion

P67A-GD65 problem with newest BIOS - no fan control settings.

After instaling newest version (V1.16) of BIOS I cant find fan control settings (2 chasis fans + % of cpu fan). Theres only smart cpu target temp. and nothing else.
is this some sort of bug, or MSI lost their minds?
Oh, and CPU phase LED's are blinking like mad (those were not blinking at all before).

Flash back to your previous BIOS and report your finding to MSI.

Apple store changed the motherboard of my MacBookPro. Have now problems with many Itunes songs.

Got problems with my MacbookPro. The Apple store changed the motherboard. Have now problems with many songs in my Itunes library. Do not have access anymore because Itunes says that I am using more than 5 computers which is not true. How to resolve?

iTunes Store: About authorization and deauthorization - http://support.apple.com/kb/HT1420 - and another helpful post: https://discussions.apple.com/message/17828050
You will have to deauthorize all and then reauthorize specific computers. Changing your motherboard has apparently made iTunes think you have a different machine.

I bought a new MBA and are having problems with HDMI and VGA port

Hi,
I just bought a new mac book air, and at the apple stre they recommended me a mosh mini to vga cabel. I need to use my computer for projector either hdmi or regular vga adapte. The new mba only has thunderbolt, usb, memory/card slot, microphone and headphone ports.
Does anyboody has and idea how i will or how do i connect the hdmi or vga adapaters to the computer. I have been searching on the cables the apple store has available but the end that goes into the computer is not compatible with the ones I mentioned above.
Please any help would be of great help, because I dont know what to do. I think this is a problem with the new MBA.
thank you,

Thank you doubr. So what I need is to buy the thunderbolt cable and the minidisplayport to vga adapter or the griifin mini display port to hdmi tht toothpickproductions recommends, is that correct?
The one I have is a mini dvi to vga adapter and the end that goes into the computer is the same one that the minisdisplayport to vga adapter or the griffin one have, and is too big to go into the new mba. I dont know if I am confusing you more with what I am saying.
check the link below and you will see the ports the mba has
http://www.apple.com/macbookair/specs.html
if you see the ports that mba has, the two minidosplayport that are recommending do not fit..
So, do you know that if I buy the thunderboldt cable will either of the two minidisplay ports fit or I need to buy another adapter for the minidisplay ports??
thank you because I am kind of confused, I did not have this problem with the macbookpro I had before...

Wake up problems with MacbookPro (Model 6,2)

Hello everyone,
I have updated my MacbookPro on lauch day and first I send a very big thank you to all guys worked on Lion. The installation process was flawlessly and comfortable. You've done a great job. Machine feels faster and working with gestures is very comfortable.
After using my machine for 2 days now I have to admit that my Macbook has several problems with waking up. If I close the lid for a few hours (f.e. over night) the fans go up after a while, the system gets hot and cannot wake up when I open the lid. The only help is hardly to shut it off and to boot it up afterwards.
At this time I will shut off the system after using it and boot it up every time I want to work. But waking up was always so perfect on Mac OS X.
Would you please fix it again, soon?
Kind regards,
m3x

No, you can't use the Thunderbolt Display because, as you note, you have no Thunderbolt port. You can use the Apple Cinema Display, however.

Problem with Facetime and my MacBookPro camera

Hello,
I've got a MacBookPro and I have a problem with Facetime and my front camera.
When I have a discussion with an iMac or an other MacBook the image received by the other person becomes fix.
To unfix it I have to put my finger on my camera and then everything is good until the next time, 4 to 10 seconds later I've got the problem again.
Perhaps somebody can help me.
My head on my screen is always good even when the bug appear on my correspondent's screen.
For information, the 2 mac have the same iOS version (OSX Lion) and Facetime version.

Hi Dave,
Edit: Well, I guess I was lost when I posted this. My answer was regarding a problem with OS X, not iOS. I'm going to leave the answer here in case someone else with a Facetime for Mac issue can benefit, because when you're searching for "Facetime AND Login", you could land in any discussion area. -Jerry

Problem with HP pavillion dv7 giving message (a problem with the internal fan enter = shutdown

HP Pavillion DV7 notebook PC
Windows 7 64
intel I5
6 gig memory
service pack 1
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
thanks

One more time - problems with fans

I realize this is but one of hundreds or possibly thousands of cases of Mac users being plagued by fan noise problems, but to me it has been a long and extremely frustrating saga. I have been a Mac user since the very beginning, through different versions of Macs and iMacs, and this is the first time I ever refer to a Macintosh as a "piece of junk."
I bought my iMac G5 in August 2005, a 20-inch ALS with 250 GB hard drive and 512 MB RAM. It worked perfectly until January this year, when all of sudden it shut down by itself. Freaked me out completely. Turned out to be power supply problem (EMC 2056) which Apple never informed me about.
I brought it to a repair shop that fixed the intermittent shut-down problem. I also added 1GB memory. But then the fans started to go berserk. Before the power supply problem, I only heard the fans whenever I used a large program like Photoshop. For the most part, it was a very quiet machine. After the power supply was replaced, within minutes of turning the iMac on, I could hear the fans spinning faster and faster, stabilizing at around 4400 rpm and did not stop spinning until I put the iMac to sleep or turned it off, regardless of CPU usage or software being used.
I checked the discussions at this forum (over 500 posts, no real answer) and did every "voodoo trick" suggested: I reset the SMU dozens of time, cleaned the inside of the iMac and around the fan area, did apple hardware test (everything was fine), monitored temperature and activity with XRG (average CPU at 160F, hard drive at 113F), cleaned out caches, tested for corrupt preferences, re-installed the original OS 10.4 (which only made the fans louder), upgraded it back to OS 10.4.9. I also removed the additional 1 GB memory, thinking it might be a bad piece. It didn't help.
Finally, I requested fan replacement from Apple and got them. I installed them last Sunday and now the problem is even worse! Within SECONDS of turning it on, the CPU T- Dio soars to around 170F, even while the machine is still stone cold to the touch. The hard drive temperature now averages at 117F, CPU fan is never below 4000 rpm (4400 rpm 98% of the time), even at 5-8% CPU usage.
The fans themselves are much quieter because they're brand new. But you can still hear the hums and whirs and it drives me nuts. More seriously, my iMac is now narcoleptic. If I use it too long (a few hours on a stretch) it will put itself to sleep, apparently because it thinks it is overheated. And when I use Photoshop or Illustrator, the awake time is even shorter. Depending on the outside temperature, at the most I can only use them for about an hour at a time. Two days ago we had heat wave, and even with the air conditioner running full blast in my study, the iMac kept falling asleep within minutes of using Illustrator.
Right now I am using TextEdit and no other program is running. Uptime is 59 minutes, average CPU 9.6%. CPU T-Dio is at 168.8F, hard drive 117.5F, CPU fan at 4400 rpm. I am out of ideas and before I do something drastic to this machine, if anyone knows what's going on with my iMac (I know every case is different), please help!

I do not have the solution... but the same problem with a nice iMac G5 purchased in July 2005.
My Mac operated very silently untill 6 month ago;problem MAY ( I am not sure) have started when I upgraded to 10.4.10 ; even with few applications and low CPU usage (80% or more inactive), it seems that I have the following regrettable chain of events;
==> the CPU temperature is quite high ( 60°c to 72°c most of the time, ie 140-160 °F)
==> resulting in fan turning at high speed ( 2.000 for CPU and system, 2500 for HD), and changing speed all the time
==> resulting in a noisy computer
I am SURE this was not the case 6 month ago, and I suspect it is linked to my upgrade to 10.4.10.
I did all sorts of reinstall, authorization repair, SMU reset, fan clean-up with no sucess.

Problems with G5 fans coming on...

I have a very early Power Mac Dual 2GHz PowerPC G5 running OSX 10.4.11 which has started having strange problems... For apparantly no reason all the fans come on and stay on - this can sometimes be resolved with a restart, sometimes not, in which case I need to shut the machine down - after which it will sometimes not reboot the first time (gets as far a blue screen then hangs) - I then need to unplug it from the mains for 10 mins or so, afer which it will start up normally.
Looking into the problem I have discovered this message in the system log every time it happens:
Jan 10 22:01:19 teknomage kernel[0]: AppleMaxim6690::readI2C error (0xE00002C2) I2CAddr = 0x98, subAddr = 0x01
Jan 10 22:01:19 teknomage kernel[0]: AppleMaxim6690::getExternalTemp read temp failed!
I have also started running a temperature & hardware monitor to try and get to the bottom of this and have discovered that all my temperatures show a flatline when the fault is about to occur. If I then restart the machine, all fans will be running. If the machine starts up with all fans running. On one occasion, CPU A showed a flatline temperature of -6.1 degrees for several hours (with the machine working just fine!) and the machine restarted into all fans running mode after this.
I have tried both replacing the battery and resetting the PMU - which appeared to fix the fault for a few days, it then recurred.
The machine also will not sleep properly - in that it won't always wake from sleep and needs a power off and reboot - which sometimes occurs with all fans running.
Apart from that the machine works fine - all my software works etc even when all fans are running.
Any ideas as to the cause? I've not changed the hardware (except to replace the battrery when the fault first started) or software for over a year. Is it case of a failing logic board or could it be something else? Any ideas on how to resolve this?
Is there any problem in running the machine when the temperature monitor is showing flatline temperatures for all sensors - or is there a lower level system that will protect the machine should temperatures get too high (maybe by switching to all fans running?)

An update to my G5 fans problem - the problem got worse, with trouble booting the machine at all. It would sometimes take up to half a dozen attempts to get a chime and then a boot :-( Sometimes all the fans would come on after a few minutes, sometimes not at all day. Sleep mode stopped working completely. As the problem was getting worse and worse, I gave in a bought another, refurbished machine identical to mine, swapped over my disks, extra memory & SCSI card and everything on tha machine works just fine :-)
I may try to further diagnose the problem with the old machine later on.

I'm wondering if anyone else has had problems with their imac fans being extremely loud when running at slow speeds? When the computer heats up enough for the fans to run at higher speeds they quiet down. New HD fan was just installed.

I have an imac that I've had for a couple years. The fans have always been loud when running at the slower speeds. When the computer heats up enough for the fans to run at a higher speed the fans quiet down. I had installed SMC fan control after multiple attempts with Apple to get the fan issue resolved. That seemed to keep the fans quiet enough. I've never had a problem with overheating. Recently the fans were becoming loud again even running at the slightly higher speeds so I took it to my local Apple store and they replaced the hard drive fan. I got it back and it's now as loud or louder than ever!! And, now SMC fan control won't "stick." The fans will speed up, but then gradually go back to the lower "loud" levels. I'm at a loss as to what to do next.

Thanks jared,
I'm still dealing with this issue through Apple. Some time after I posted this, I contacted Apple again. They did start a case up for me, as I was experiencing the same behavior on two different machines, with two different versions of Windows.
So far it remains unsolved. I've logged iClouds for Windows on my desktop, which is brand new, then logged for awhile after completely uninstalling Norton Security Suite, depending on the Microsoft security for some time, and finally logged after I uninstalled iCloud for Windows, restarted, installed a clean download, and connected using a completely different test account, which Apple set up for me. None of this made any difference. Looking at the logs, it seems every 10 minutes, iCloudServices.exe creates a new TCP connection to confirm I'm using less than 5GB on iCloud, (which I am by a good margin, using less than 2GB), it seems this connection is not closed, and when the next iteration rolls around 10 minutes later, a new TCP connection is created. I come very close to having 6 TCP connections created per hour, until I restart my computer. This works out to... 6 x 24 = 144/day.
Perhaps the article you posted will shed some further light on this. I'm thinking seeing the state of the connection through netstats, at the least, could help.
For the last week, I've been putting a hold on further logging, as Apple wants me to create a new user account on one of my computers, install iCloud for Windows there, and log it running in the other account. This however basically means I cannot use my computer for a fair number of hours, and I've been busy enough with work the past week that I haven't the time or energy to afford to set this up and run it. I've had need of my computers too much for the past week.

Problem with fan speed on FM2-A75-P33

I have a problem with setting a lower cpu fan speed on my motherboard (Win7 64).
It always runs on high speed, and I can not decrease it. When I set values for min speed in ClickBios II (or manually in Bios before booting) to 0%, and desired temperature on some higher amount (60C), nothing happens. It always run on same high rpm, regardless any change of values. What can I do? Same thing with sys fan.
Live Bios says that I have latest version of BIOS and drivers.
thanks

That is odd. Only thing I can think of is maybe a conflict in settings between Click Bios and actual BIOS. One of the reasons I never use those programs. I'm not sure what to tell you, except that the fan speed settings on my board have all worked properly using standard BIOS settings.
If I was having issues I'd uninstall click BIOS and see if the issue continues. At least then you would know it's something else.

i already reinstall the software many times and still the same i dont know what is happening is there is somebody who can help me please im will waiting

There are any number of possibilies... you could have problems with runaway applications, causing your machine to overheat and setting the fans off, you could have bad fan sensors, etc.
Open Activity Monitor (Applications>Utilities) and see if you have any apps that may be hogging the CPU. Call back.
