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!!!!!!!!!!!!!!!!!!!!!!!

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?

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.

CPU Fan going crazy (over 3500 rpm) all the time iMac 24"

Hello,
I have had an iMac 24" since Aug 2009. I had no problem until up a month ago (coincidentally after I installed Mountain Lion).
The CPU fan becomes very noisy, reaching 3500 rpm and more. I checked and the CPU temperature is around 90C when this happens.
It happens invariably after very little usage of the computer. Sometimes it's when I'm watching a DVD, sometimes is when I'm copying files from a USB hard drive, sometimes I'm just surfing the web.
I have brought my computer to the Apple Store twice already. The first time they told me I should reinstall the OS from scratch, after erasing the disk (which I did), the second time they told me they had found the problem and fixed it, for free! but it presented itself as soon as I turned it on back home.
The CPU temperature is around 80C right now, and I only have safari opened and I haven't reinstalled any program since I reinstalled the OS.
Do you have any idea of what it could be? Could it be that the sensor is detecting a wrong temperature? In this case, could I set the fan speed manually? I know it is not advisable, but the people from the apple store are not helping
Thanks for any help you could give me,
Biagio

Please start by doing a SMC Reset,
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
If necessary repeat process.

Fan runs at full speed all the time

The fan on my brand new iMac 17" runs at full speed all the time, creating an unbearable amount of noise. The activity monitor shows 99% spare time, i.e. nothing much is running.
I updated all software, checked the firmware version (it was the latest already) and performed an SMC reset. I also unplugged it for several hours, as some people have suggested.
I downloaded smcFanControl and it says that the ODD fan is running at 5200 rpm all the time. The CPU and HDD fans seem to run at normal speeds. smcFanControl also reports a cool 39 deg.
Does anyone have any idea of what to try to fix this problem?

I don't have a solution but thought I'd add a computer that showed the same behaivor.
A 20" iMac I was configuring for my company did the same thing, but just once so far. I used it briefly just out of the box and didn't have any problems. It's a stock install of OS X 10.4.8, no other software installed. Turned it on several days later and the fans ran during the 2 hours I used it to run Safari via Airport. I turned if off after it started to smell like hot electrical components. Activity monitor looks completely normal. After shutting it off for two hours, unplugging and re-plugging AC and keyboard, it came back on with no fans. I did not do the SMC reset or any updates between the power cycle.

IMac Fans running at maximum speed all the time

Hi Appleians!
I have an iMac 20inch with 8GB RAM and its an i3 intel processor. I purchased it from a friend of mine who had replaced the original hard drive with another that amounts to a terabyte. Now the fans are running at full speed all the time making it way too noisy to work with. It however works smoothly with no problems except the fans are irritating, it does not heat up though. Anyone with a solution? I tried resseting the SMC it didnt work.
`Oh and the computer is running on Mavericks.
Please help!

Fan runs at max almost all the time on a 2.16GHz MacBook Pro

My fans are running at 6000 rpm for no reason. I've noticed this for a while but now I realize something is wrong.
I tried resetting the SMC (pulled the battery, held power button down for 5 seconds) and no luck. As soon as I turn it on and it comes up with the log in screen, the fans are running at 6000 rpm. I have 51 processes running right now and the one using the most cpu is activity monitor at about 2 to 4 ('m assuming percent).
I'm wondering if there is another way to reset the SMC on a 2.16GHz MBP?
And has anybody else had a similar problem?
Should I redownload and reinstall the firmware update for this model, I think I recall a while back a fan firmware update for it?

I've had the same problem.
On my 2.16 C2D MBP it was the thermal sensor of the GPU's heatsink that was intermittendly losing connection (you can see that in programs like Temperature Monitor and Hardware Monitor).
I opened up my MBP and reseated all the little sensor connectors I could see and now it works again...
First I'd run Apple Hardware Test from the installation DVD, it may throw an error that you could post.

My fan(Left only) is running at high speed all the time since last update. Any ideas? (Mac OSX version 10.7.5 on 27" mid 2011)

My left side fan is running at full speed all the time. I have downloaded free fan speed control app but does not help. Any advise

Fan Control Apps/Utilities generally can only raise the speed of the fans and not lower them.
Disable, turn off or uninstall whatever Fan Control that you installed and reset the SMC.
see > Intel-based Macs: Resetting the System Management Controller (SMC)
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.
Then if the iMac's fan is still running fast, you probably have a loose sensor cable or bad thermal sensor and the iMac needs to be taken into service

Macmini running at 1.83GHz all the time...

My Mac mini CD 1.83 arrived yesterday. I am surprised that it runs on 1.83GHz all the time even I only open Adium and Safari (but doing nothing). Does it sound alright? cause the temperture stay on 55-63'c all the time, will it be too hot? Any feedback is great....Thanks in advance.

You raise some interesting points, to which I would like to respond - as much from curiosity as to your conclusions and observations as anything.
"smcFanControl" is a small app that will allow you to
set the minimum fan speed to a higher value than the
default 1500rpm. I have now set mine to 1750rpm and
the temps are now46/39C (core1 and core2). HD is
44C.
I can't entirely understand in what way users of this software feel the standard fan control based in MacOS is deficient - and that if it is in a specific system, why it would not be considered better to have that fault resolved rather than circumvented. That someone has written software to control the fan does not, in itself, suggest users would be wise to avail themselves of it.
I can not exclude the possibility that this may
decrease the life expectancy of the fan, but it
should definitely INCREASE the life of the
logicboard's components and harddrive.
'Should definitely' is a good disguise for lack of certainty! There is, for example, no indication that the design of the Mac mini's logic board would benefit in any way in common use from running cooler, and to take one of your later points regarding not wanting to cause vibration by use of the internal optical drive in order to avoid damage to the logic board, no reason to believe that the increased fan speed you have selected will not cause greater vibration impact over time anyway. That said, there is nothing to indicate that the logic board suffers from vibration damage anyway, but if it does as you suppose, then surely fan speed is just as much a potential culprit.
Someone else has reported that removing the top case
lowers the temps 12C,so it seems the Mini IS
suffering from it's diminutive size, not
unexpectedly..
It is self-evident that removing the casing would cause the system to run cooler, as would be expected in any conventional design where a box encloses a heat-generating source. The issue isn't whether it runs cooler that way, but whether the heat levels when running in more conventional 'assembled' mode are in any way damaging to the system.
There is always the possibility that your supposition is right, but if the history of laptops, for example, is anything to go by it would seem likely not. I have both Mac and PC laptops that have been in service for many years combined service and suffered no ill effects of temperature, vibration, even minor impacts and general handling abuse - things which the manufacturers (including Apple) have clearly designed the product to cope with. It is certainly true that both my iBook and TiBook run much hotter than my mini, that their optical drives create far more vibration and their cooling systems are far more challenged by cramped internal design, yet they both function flawlessly, despite continual heavy use. My experience is not, as far as I know, untypical. It leads me to believe that Apple have some competence in their design of products, and that they actually do know what they are doing.
Ultimately, given that the mini is heavily based on laptop technologies, it seems to me there is no reason to believe it will fare any worse in reliability and capacity to cope with heat and vibration than laptops do - and it certainly has more internal 'space' to allow air circulation.
However, removing the top case will expose it to
RFI/EMI, so the chance of it crashing due to nearby
radio transmissions will be somewhat higher..
Not really. The sides and base of the mini are metallic, though the clips that hold the sides to the base are plastic and there's no indication of a solid electrical contact which would help screen spurious RFI. The top panel is, however, a form of plastic, which has no RFI screening characteristics, so any stray radio frequency energy in the area is capable of leaking in there. Radio frequencies are not particularly directional (except when approaching microwave levels), and the worst common RFI generators are typically VDUs, which are normally above the mini anyway.
Much more of a problem than RFI getting INTO a mini is RFI getting OUT! The top panel is transparent to radio because both Bluetooth and Airport antennas are inside the unit under the top and they have to be able to 'see' out, and computers typically generate far more RFI than they are likely to receive in a normal home. Try putting a mini next to an end-fed wire antenna connected to a shortwave (HF) transceiver or receiver. The lack of screen on the wire allows a lot of stray RFI to get into the signal received! People generally don't notice RFI at that level anyway, and of course most modern domestic appliances, such as TVs etc, are designed to screen it out.
My personal choices are intended to make the mini
live as long as possible, and this includes not using
the internal optical drive AT ALL, since any
vibration from this will be transferred directly down
to the logicboard. This is not really my idea of
healthy design..
I can't disagree with the notion of using an external optical, though in my view not because of vibrational concerns, but simply performance and usability. I think all the indicators are that Apple's designers know far better than I do about what the system itself can cope with and how to design it to be robust enough to withstand time, but the optical drives used are frankly not that wonderful in terms of performance, and can be problematic to extract a stuck disk. An external allows the user to select a unit which specifically meets their need, and is more likely to allow easier retrieval of disks in the event of a failure.
Seems to me as if Apple's priorities were to make it
small, good looking and quiet, and they succeeded in
that. I wonder if life expectancy were ever part of
this equation..?
You imply it wasn't, but there is no evidence of that being so, and plenty of evidence it was. One has to accept that no modern product is designed to last an eternity, and the mini is certainly no exception, but as far as it is possible to tell from a model life that is still a little under 2 years, there's no indication that the mini will not last as well as any other system. certainly in my experience, one of mine has been running 24/7 since the end of January 2005, and it shows no indication of getting tired or suffering any problems - and I can tell you without any doubt that in that time it has suffered a far harder working life and higher consistent load than the average home system would get in twice that time or more.
A number of Apple's designs in the past have shown
that thermal management is not really their biggest
strength, so a little self-help here can go a long
way..
I can't help but wonder what you mean by this. I own three Macs which specifically are famed for high temperatures; an iBook, a TiBook and a G5 dual processor powermac. The laptops run hot, as laptops do, but are clearly designed to cope, and the G5 has incredibly efficient cooling which means that for the most part the fans barely do more than idle - indeed, the cooling of the G5 is really a masterpiece in its own right. Given that the switch to Intel results in lower overall heat generation than the PPC counterparts, it allows Apple to design systems of far greater power than was possible before without increasing heat generation beyond (or in many cases such as the Mac Pros, even as high) as those systems that went before.
For example, to get similar performance from a PPC mini that an Intel model is capable of producing, would have required a G5 (or indeed, dual G5s) which would have been impossible to accomplish in this sort of design. The Intel chips now being used allow substantially better performance without markedly increasing heat levels - indeed that was the argument used when justifying the switch. Intel minis do run hotter than the G4 models did, but at substantial gains in performance.
I'd say that makes for good thermal design - understanding the limitations of the physical space and ensuring the product is engineered with those factors in mind.
Overall, I think you raise some great issues for discussion, and no small number of common concerns. But, for example, the simple issue of heat levels, often argued as critical to component reliability because of heat stressing, ignores the fact that component and board tolerances and manufacturing standards have improved radically, and that in reality it's not, within operationally tolerable margins the temperature at which the system runs that is the actual problem, but the width of variation of temperatures as the system is in use. Variations around the steady-state operating temperature are what causes the worst effects of heat stressing, most likely to cause component failure, not the steady-state temperature level itself.
Anyway, I didn't set out with the intention of trying to demolish your arguments, and I hope it doesn't come across as such - indeed, quite the contrary, I wanted to explore the thoughts and issues because they are interesting and of no small value to the community of owners overall.

Should I run Firefox with Rosetta all the time?

I was just wondering if it's a good idea to run Firefox with Rosetta all the time or will the browser run faster if I turn it off when it's not needed?
I need to turn it on enough to make me think it'll be easier for me if I leave it on all the time.

It will run faster and use less memory if you let it run natively- whether the loss in speed is made by the convenience of not having to switch it (for whatever reason you're switching) is a personal calculation.

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?

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-

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.

Mac mini Intel Core Duo fan very loud and runs at high speed all the time.

I purchased an "Open box" Mac mini Intel Core Duo, 1.66Ghz, 2G ram, 80G HD and SD a few days ago from Fry's.
It runs beautifully except the fan is very loud compared to any Mac my family has ever had. It is so loud that we were thinking of putting it under the desk.
The fan runs constantly, and I mean all the time, at a high speed. You can really feel the air coming out the exhaust vents. The case is always cool to the touch as is the exhaust air.
My aunt bought a similar Mac mini (But only 512Mb ram) the same day. Her's is very quiet. The case feels just slightly warm, not unlike other Mac mini's I've seen.
Should my Mac mini's fan be running this way?
Thanks,
llulua
BTW: The "open box" was sealed with a Fry's label and it said that this had a new warranty. Yet, checking the serial number, it said that it had about 260 days left. I guess Fry's is backing it?
Also, someone told me that perhaps the main wire from the fan to the logic board is disconnected.

eMac 1Ghz, iBook 500 dual usb, Mac mini 1.66Ghz Intel Core Duo 2g ram Mac OS X (10.4.8)

Since you have 2 gigs of memory, my thoughts are that when the party (Fry's or the origianl purchaser) upgraded the memory, they neglected to reattach the wire at the front of the Mini under the IR receptor at the right front corner that regulates the fan speed. This wire must be unattached in order to upgrade the memory, and is probably why the original person brought it back, because of the fan noise resulting from failing to reattach the wire. If that wire is left unattached, the fan runs continually at high speed to protect the CPU and system in general. If you do not want to use a putty knife to open the Mini, take it back to Fry's and ask someone who is Mac savvy to open it and reattach the small plastic receptacle at the end of the wire into its socket at the right front of the machine. When I go to Fry's, I am always concerned because the employees allow people to pry keys off of the Apple notebooks, so don't expect that their employees to know or care about anything Mac.
