Fans are running at 6000 rpm at all times.

Hello I´m from Germany an try my best to explain ;-)
in my MacBookPro2,2 Intel Core 2 Duo 2,16 GHz the fans are running all the time without stopping.
When I start the MacBook the fan start to run at maximum.
It is making me crazzy. Please help me. SMC Reset and cleaning the Fans and what ever else I did does not help.
I tried a tool to find out whats up?

Nothing is really hot?
Hope you can help me ;-)

Run the extended version of the Apple Hardware Test that you'll find on one of the DVDs that were shipped with your MBP. I expect AHT will report a SNS error, indicating that one of the temperature sensors in your machine has failed. When a temp sensor fails, the fan or fans usually run at top speed all the time as a precaution, in case the machine is overheating but the bad sensor is failing to report it.

My fans are running at 6000+ RPM all the time - new MBA 1.86

I have a new MBA 1.86. It seems like the fans are constantly running high at 6000-6200rpm while only running a few apps (Firefox, iTunes, VMware).
Is this normal?

i was such a big fan of apple but now using the 1st gen macbook air has begun the pain it works very sluggishly cannot watch videos on youtube it gets freaking hot and then the os becomes so sluggish i have to close the lid and reopen but every 10-15min interval i've to do it.I tried contacting apple did every possible thing but didnt get any solution so have planned to sell it off and buy alienware as it is the best powerful machine,in india no proper support for apple no proper repairing guyz really screwed up this time buying MBA iam **** up now apple better take some measures or discontinue MBA coz everone is complaining abt overheating!!!!!!!!!!!!!!!!!!!!!!!

HELP ME !!!! My MBP fans are stuck on 6000 rpm

I recently cleaned the right fan on mbp because it was making a grinding noise . I then ran smc fan control to make sure that my fans were running well , now everytime i switch on my mbp the fans rev up to 6000 rpm and stay even if no programs are open. My temps are averaging around 35 celcious . I have tried everything , smc reset , pram reset , osx complete reinstalation and also tried to do a firmware restoration . None of these things have worked . Please help me

Have you tried running the Apple Hardware test? I'm wondering if a thermal sensor may have become dislodged or unplugged, as that would also cause the fans to run all out.
Also, have you checked in Activity Monitor to be sure you don't have some hung up process hogging the CPU and causing the fans to run all out? Be sure to select "CPU" on the bottom bar and "All Processes" on the top.
Good luck!

Fans always running at 6000 RPM.

I have had this problem since my friend gave me his old macbook pro. The fans are very loud and running very fast. First I thought dust might be stuck inside but I checked and nothing was there. Nevertheless I cleaned it. When I powered on my macbook it was still very loud so I checked with SMCFanControl and it was still running at 6000 RPM. I have tried resetting PRAM and the SMC without any success. Also software like SMCFanControl and iCyclone won't let me change the speed even though the CPU is at 40C most of the time. I don't really want to take it for repair at the apple store because they will probably charge me a fortune. It is a MacBook Pro Late 2006 model. Thank You.

Same situation here - the only update: it started to happen after I replaced the palmrest, screen assembly and installed SSD Intel X25M drive. First, at startup fans are quiet, and then slowly going to higher speeds. Since I did upgrade everything at the same time I did not catch what was the source of this issue. First I blaimed SSD since it's not getting any warmer (as oppose to standard SATA drive) and that might have confused the Mac's fan control. The other thought was the SSDs have a different SMART reporting method... Well, all kinds of resets (SMC and PRAM) did not help, neither utilities like smcFan Control and others. BTW, smcFan control shows temps from 35C-37C and 5200-5500 RPM. Fans are blowing a cool air, no signs of overheating at all.
Bad temp sensors?
Any thoughts?

Why do both fans always run at 6000 RPM

I have a 17" MB Pro which spins both fans at 6k ALL the time (when it's on), even though the machine is not running hot.
They go off properly when it's in sleep mode, but after wakeup or restart the fan speed will start out slow (and inaudible), then slowly increase until after a minute or so both are running at max speed.
CPU heatsink temps are in the 93 - 95 degree (F) range.
I have reset SMC, deleted com.apple.PowerManagement.plist file, same behavior.
Any thoughts on this? The noise is getting to me.......

I have just begun to have the same problem as of last night, also with a 17" MBP. I spent time on the phone with an AppleCare rep, but the fans stopped on their own after a reboot into Windows and then back into Mac OSX. As of right now, they've started again.
As in the case of the first poster, my computer is not running hot, nor is any process taking up a lot of CPU cycles. This is really perturbing me.

Hard Drive fan suddenly running at 6000 rpm

Hi, I have a 2009 20" iMac, 2.66GHz Intel Core Due running 10.5.8. I have iStats Pro and SmcFanControl installed.
Randomly, my HD fan goes from 1099 to 6000. I can fix it by putting my Mac to sleep, wait for 10 seconds, and then proceed, The HD fan speed goes from 6000 down to 1099 and it will stay there. Sometimes this hapens a second or 3rd time. Every time I put the machine to sleep. And every time it "fixes" it. After 3 to 4 times going to sleep, the problem weems to be permanently solved and the "vacuum cleaner" does NOT turn on anymore. Obviously, this is highly annoying and not a solution.
Is there any real solution to this problem? I bought this machine in July 2009, no Apple Care because I have had luck with Apple products in general (my iMac DV from 1999 still runs...). It seems as if my luck has run out.
I scoured the boards but nobody seems to really know what is going on. I read about temp sensors and logic boards. Seems dramatic to me. Is this something I can fix myself?
Has Apple recognized this as a real problem??? Because it IS! I am very disappointed. You do not expect this from a newer machine.
Thanks for your help.

First off smcFanControl is not going to fix the problem, it can only run the fans faster and not slower than the iMac's System Management Controller is telling them to run.
It sounds as if you have either 1 of 3 problems:
1. you need to reset the iMac's SMC.
2. the Hard Drive is actually over heating for some reason.
3. you have a faulty HD temperature sensor or bad connection (wire) between the sensor and logic-board.
I would do the following:
1. disable or uninstall smcFancontrol
2. reset the iMac's System Management Controller
as per > http://support.apple.com/kb/HT3964
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Press and hold the power button for 5 seconds.
4. Release the power button.
5. Attach the computers power cable.
6. Press the power button to turn on the computer.
3. then if and when the HD fan acts up (ramps to 6000rpm) run the extended Apple Hardware Test
as per > http://support.apple.com/kb/HT1509
4. use the iStat Pro widget to check the sensor readings for the Hard Drive and Hard Drive bay when it acts up.

Will fans running at 6000 rpm hurt my macbook pro?

Whenever I run certain programs the fans will run at 6000 rpm after 20 mins or so. The actual temp of the computer will reach 80C max but the fans seem to be working very hard. Will this harm my computer?

Yes and no. The fans are spinning at that speed to try and keep the system cool. That is normal. But the excess heat being built up from that program will cause parts to ware faster than less heat.
Will it cause the system to fail sooner than later? Maybe then maybe not. Each computer is different, even of the same exact model. Some last a long time, other don't no matter how they are ran or treated.

Post serviced IMac and the fan is running at top RPM.

I had my IMac serviced doe to the HDD dieing. When I got it back, the HDD fan is running at max RPM. I've tried to reset the PRAM (7 times, over and over) and tried to reload the SMC patch and no luck. Apple Store is over 2 hours away so I'd like to save 8 hours on the road by figuring our if there is anything else that I can try to fix this.
C2Duo IMac with Tiger and the 'fans played on' from the moment I got it back and started restoring the data.
Any ideas?
Also, a new AppleCare agreement talks about 'onsite service'. Do they actually do onsite service? Does one have to request it? It wasn't offered when I called in after finding the fan issue.
Thanks!!!

So, I called AppleCare and they walked me through an 'SMC reset' routine and now SMCFANCONTROL doesn't run AND all the fans sounds like they are running at full speed.
I got a call that they want to swap my system rather than have me wait for a new sensor. I wonder what issues I might have with a 'refurb' system.
There is another issue, there is a smear of some kind of glue on the screen from the service experience.
It's been interesting dealing with their support...
I can't stand the whine of the fans and now am back on Windows for most things. Yippee...

Fan always running on my HP Pavilion All-in-One 200-5000 (model #2MD0400F1W)

The fan on my HP Pavilion All-in-One 200-5000 (model #2MD0400F1W) seems to be always running (and it's not quiet). I believe I'm running the latest BIOS and I've already checked to make sure the air vents are clear. I'm not running any memory or processor intensive applications. Any suggestions how to reduce how long and frequently the fan seems to be running? Thanks.

Cpu fan is running at -1 rpm!!

h, i've been facing slight problems with my mac that it overheats sometimes, so after some research i found out that i can download a program called fan control where i basically can control the speed of my fans. then i found out that my cpu fan is running at -1 rpm, the desired rpm is 300, my other fans (hd and dvd) are running at the desired rpm, i'm not sure if i should be worried!!! i mean do i have to replace it!? and if so where and how!!!?? btw i've just got this laptop used, it's a 15" late 2008 with the highest configueration.

Resetting the SMC was my first thought, but you have done that. You might also try resetting the PRAM/NVRAM:

After that if the issue persists, I would call AppleCare.

My macbook pro keeps zapping me. even when the charger is not plugged in, my hands keep feeling tingly and the fans are running louder than usual

over the last two days since i updated my software, my laptop seems slower, the fans are running louder, and i keep feeling mild shocks (even without the charger). my hands feel really tingly and a little sore. what is going on?

cheesecakeyumm,
have you tried resetting your MacBook Pro’s System Management Controller? (I don’t know if that would have any effect against mild shocks, though.)

I have a new Macbook Air and for the last few days the fan had run continuously, this is the first time it has ever run, and now it won't stop, the fan starts up as soon as I turn it on. The computer is not hot.Any ideas on how I can fix this please ?

I have a new Macbook Air, 6 months old, and for the last few days the fan had run continuously, this is the first time it has ever run, and now it won't stop, the fan starts up as soon as I turn it on and the computer seems to running more slowy.The computer is not hot but I am worried it may burn out,.Any ideas on how I can fix this please ?

Hello dwb,
Here is the screen shot, just the top half, there are another 10 pages, but I guess this should enough for you to have an idea of waht is going on, bit small I am afraid. No, I don't have any apps setup to run when I open my computer, the kernel, varies between 290 and 305 per cent ish.
Would that PRAM thing help ? I think it may be the computer itself, well something inside, as this the first time that the fan has ever started running since I have this computer, even when I have 3 or 4 apps running.
Thank you again for your advice,
Regard,

Fans are running on high at all times

for some reason the fans on my computer are running oh high at all times. from the second i turn my computer on, even if the computer has been turned off for days.
does anyone know why this is?

Hi chasensanborg-
Try it with the drives disconnected. If the problem goes away, try plugging the drives in one at a time until you find the culprit.
LaCie drives tend to have power supply bricks that fail intermittently and get progressively worse. The symptom is difficult to troubleshoot as the drive will attempt to pull whatever power it needs from the FireWire bus if the brick is not supplying the right amount of juice. This can put a load on the power supply of the Mac and cause the fan to run more quickly in order to compensate for the heat generated by the load.
Luck-

Loud fan, won't stop running at 6000 rpm.

So I'm a first year law student and had my 2010 macbook pro stolen from me 2 weeks ago at school and with exams + finals coming up I desperately needed a new computer fast. I only had $600 and wouldn't settle for a PC so I chose to buy a used macbook from a random guy on craigslist. I bought a late 2007 15" macbook pro that has snow leopard running on it and for some reason the fans are quite noisy. Normally I would take this issue to the apple store but I obviously don't have applecare on this. The previous owner had installed smcFanControl on it, which I hear usually does more bad than good... now I have no idea how to make the fans quieter, adjusting the speed only works temporarily. This is the 3rd mac I've owned and I recall my first mac being somewhat noisy too after a few years but not this bad. It's become impossible to use my computer in lectures or the library without getting death stares from people trying to concentrate, any help/advice is much appreciated! Thanks.

I'd try uninstalling smcFanControl and then doing a SMC reset to set things back to normal.

My Macbook's Fan Constantly Runs at 5600+ RPM

have noticed that for the past few days, my fan was running all the time,and very loudly from the time I turn it on, until I turn it off. I got istat pro and saw that my fan was running at 5500-6000 rpm all the time. Can anybody tell me whats going on?

Yes, do a reset and if you are running something like Parallels. It does use a lot of CPU cycles which heats things up. Open up your activity monitor to see how much CPU percent you are using when the fan is running high. It will also tell you what programs are using it too.

Fans are running at 6000 rpm at all times.
