Continuous fan running?

Hi,
i have a problem which has just started in the last few days. i have only had the iMac for 3-4 months from new?
my fan will not turn off.
i have unplugged etc as suggested in other forums but it still starts up and doesnt stop untill i shut down or put in sleep made.
I have a
MAC OS X version 10.6.8
processor - 3.2GHz intel core i3
everything else is working perfectly, no lags etc to report. its just the noise that is getting me......
thanks

If an SMC Reset, which you appear to have tried by leaving it unplugged for a time doesn't work, then run the Hardware Test in Extended. Could try leaving it unplugged for 30 min, then hold in the power button for around five + seconds before plugging and restarting.

If it's new, get it repaired under warranty. And good idea to buy AppleCare, which must be purchased before end of first year.

IMac Fans continue to run after iMac puts its self to sleep Automtically

My iMac fans continue to run when it puts its self to sleep using the energy saving preference pane in settings. The iMac sleeps normally, The Fans Turn Off, hard disk sleeps and all when i press the power button and do it manually but not when it does it automatically. Does anyone have a fix to this as i need it to sleep its self for the new free government EnberTech Power Saving AC adapters to automatically shut off all of my connected devices

Imac (Intel based) fan runs continuously and loudly.

Have done a SMC reset, and the fan is still running loudly and continuously. Only 1 application open - firefox. This has been an ongoing, continuous problem.
Thanks in advance for any help you might offer.

Have had the same problem .. have reset the PRAM & SMC, doubled the amount of RAM. Fans runs & Activity Monitor shows most of RAM is used up with nothing open. Running Snow Leopard 10.6.8 on a Mac Book with 4g of RAM, Apple Support showed no hardware problems. ????

Whenever I run Firfox 4.0, my computer fan runs continuously. I have disabled all plug-ins, and I get the same result. This did not happen with Firefox 3.x, and it doesn't happen with IE 8.0. Any ideas?

I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.

Finder makes fan run loudly and continuously.

I've had my MacBook for only a few months now and I am having a problem with the fan. It starts running loudly when I am doing simple tasks, such as viewing a webpage which contains no flash, video, or similar content. The fan does not stop running unless I put my computer to sleep or restart it. I have found that by relaunching the Finder, the fan almost instantly slows down back to its normal state. This concerns me as this has been occuring more frequently over the past two weeks. Is there some sort of fix to this instead of having to relaunch the Finder every time?

Yes you can continue to play games but heat is the bane of electronics and in time there will be a cost. When is hard to say, but I can put it this way, a fan running constantly at high speed is more likely to fail sooner than one at a slower speed.
Ciao.

Fans run continuously @ 6000rpms

I just got a new 17" Unibody 2.66 and the fans run continuously at 6000rpm.
For example, right now they are running at 6000 w/ temps of:
CPU A - 35
GPU - 36
GPU Diode - 38
GPU Heatsink - 30
This is on a clean install with only Safari running.
What's the deal?

There could be some problem that doesn't show up on the AHT, like maybe a loose mounting screw or some tape interfering with the air flow or something along those lines. The fans should be silent when idling. So my guess is that there is still something wrong, but it will take someone actually opening it up and looking. It sounds like a mechanical problem of some sort.
Ironically, "mooing" was a problem with the first original MBP's that came out.
I think it's time to take your MBP into an Apple Store or call Apple to have this looked at.
Good luck!

Fans run continuously on my iMac(1 day old)

I don't know whether anyone might be able to assist, but the fans run continuously on my barnd new 27" iMac.
I have upgarded the HD to 3 TB anf the ram to 12 GB.
I have reset the smc some 4 times.
I do not know what else to do.
Any suggestions are most welcome.

I second Paul_31. If you haven't called Apple by the time you read this, you ought to do it now. You have a brand new machine. Don't try any more "fixes" until you call Apple.
Equally as important, whether they replace the machine of fix the one you have, you really ought to consider purchasing Apple Care. It extends the warranty to 3 years and gives you access to tech support for the additional time period at no cost.

Fan runs continuously after Update to Leopard

Hi,
after updating my macbook pro to leopard after a few minutes the fan runs continuously. I think the problem is the bluetooth process, which consumes 56 % of the cpu. The bluetooth firmeware is 2.1.0f17. I have installed the latest updates 10.5.3.
Can anybody help?
Thank you.
Susanne

Welcome to the Forums!
Assuming you're using Activity Monitor to identify the offending process, you can quit the process from there. Does it return after a reboot?
Hope this helps...

How do I stop my fan running continuously?

My fan runs continuously and is very noisy. I have reset the SMU but the problem persists.

Hello
first question to ask is , why my fan run continuously ?
try use Apple Hardware Test software to answer , could be a temperature problem , fan problem , temp sensor problem ..
AHT is locate into your original grey CD , try run and report any error may help to understand your problem
AHT could be run to hold on at start up "D" key on keyboard , depend on your imac model / system version

Macbook fan runs continually with Zynga games...

My wife reports that her Macbook fan runs continually when playing Zynga games...internet games in facebook. I watched her, and it's true...if she quits the game the fan stops. Is this a potential problem? Seems that's all she does on that laptop... I suggested she stop playing the games, but that advice will not be heeded:) thx.

Thank YOU for the reply. Wanna nother star? Help me figure this one out:

Fan Runs Continuously

My fan started running continuously after using the computer to stream a movie to HDTV via an HDMI port. I loaded SpeedFan and my temps are not high (40-48 C). Customer support had me update WinFlash, reinstall power management, and install ICH9 Chipset. This didn't work. There's no dust in the way. Any ideas? Thanks.
This question was solved.

Hello,
Are you saying that after this the FAN runs all the time now?
You can change the "fan always on " setting in F10 Setup..
Just hit F10 when you see the HP logo on startup and make the changes..
This will depend on what model you have
I am an HP employee.

Fan runs continuously on my Powerbook G4

I remember buying my Powerbook G4 Titanium back and then reading the review after I already had the computer at home. The review complained that the Powerbook ran hot.
This has been my experience. I can't hold it in my lap without a pillow to buffer the heat and the power button is hot enough to hurt a little if you hold your finger on it.
The real issue now (I can't remember how long this has been a problem, seems like years) is that I can hear the fan run continuously and it makes a loud whistle. It's distracting enough that I can't take my laptop into a library without disturbing everyone else.
Has this been your experience? I know G4 PBs have run hot from the beginning, but am I stuck with this noisy fan? I don't know if a new fan will be any quieter or what to do with this thing. I'd hate to replace the fan (that can't be cheap) and find that I still deal with the same distracting noise.
By the way, the fan runs right from startup, even before the computer has gotten hot.

ps, By the way, I've opened Activity Monitor and there is nothing using up the %cpu. I'm at about 20% of capacity with two or three apps open.

Even if the fan is running continuously, if I get a brand new one installed, I would have a quiet computer again for the year or two that I plan to still own this thing, correct?
Hi John,
No, I suspect that is not correct. The fan is simply a motor. It either runs or it doesn't. If it does, it is functioning properly. If it runs when it is not supposed to, the fan "controller" is not functioning properly. If the fan controller and the fan ARE functioning properly, then the logic board itself is running too hot for some reason, which, in your case, I suspect is the truth.
TiBooks (and some others) have long had heat issues. I have long suspected that it wasn't the actual design, but that some part of the very complicated/integrated physical system had been compromised. In many cases (and possibly yours), I suspect it's a breakdown of either the heat sink itself, or, more likely, the heat paste that "connects" the heat sink to the CPU (and, depending on the laptop, other heat sinks as well); thus, the path which the heat is supposed to take, from CPU (or elsewhere) to the heat sink/and/or fan, is "broken" and the heat cannot dissipate as well as it should. Hence, the fan runs on and on. My .02, fwiw.

Portege R500 connected to mains - fans runs continuously

Have an R500 for some months now and the more i use it the more the fan is giving on my nerves even in the lowest whisper.
And it is really a pity because from any other aspect i love this machine.
My solution is to try to use it always on battery instead plugged because if plugged the fan runs continuously even when the temperature is below 50 celsius while on battery even if it reaches 60 it isn't spinning at all.
So could you please tell me if there is any solution to fool it and while plugged make it believe it is on battery?
Thanks.

Hey claw
If you are writing about power saver mode or power saver plan in power settings it is not the same what Jaba wrote.
To set cooling fan to lower method please do follow:
Control Panel > Power Options > Balanced Change Plan settings > Change Advanced power settings > Toshiba Power Saver Settings > Cooling Method > Plugged in set it to Battery Optimized.
I have done the same on my notebook and it runs quieter as before.
Please test it on your Portege notebook.

S12-ION Fan running continuously.

Hi all,
Dunno if this is an problem or not - I have an S12-ION and just recently it's started running the fan all the time (irrespective of CPU load).
Is this a sign of a heat problem?
And, if so, is there anything I can try doing to rectify it?
Or should I just not worry?
(It didn't used to do this - previously the fan would only spin up under high CPU load, now it's spinning all the time)
Scott

Hmmm....
Actually, again, having thought about this some more...
Why?
Why on earth would I want to uninstall my virus scanner?
And leave my netbook vulnerable to attack?
Because the fan's spinning?
Maybe this makes sense in the world of laptops/netbooks - I dunno this is my first laptop/netbook - but, it seems rather like cutting off ones nose to spite one's face.
Also, if it were a software/update issue, wouldn't it just reappear when I reinstall???
So what would I achieve by doing a recovery and re-install, other than wasting my time?
Or is it a case of windows getting clogged up, and so using more cpu's cycles, and so the fan runs more?
Could anyone else confirm that doing a restore and reinstalls is worth doing?
I'd rather not spend days doing something that's not going to make any difference.
But, I'd also rather not ignore something and put it off, just because I don't understand why it should be that way.
And, please don't take offense at this, yigit, but, "reinstall everything" sounds like the sort of advice someone that doesn't actually know what they're talking about would give.

Airport time capsule fan runs continuously

My airport time capsule fan runs continously

I am assuming that you have one of the new 802.11ac Time Capsules ... correct? If so, the internal fan on these base stations are thermally controlled and would run when required.
This would, most likely, mean one of at least two things: 1) The ambient temperature around the TC is too high, or 2) The thermal circuit that controls the fan is faulty.
Be sure that you are providing adequate space around the TC for proper cooling and that you are placing it on a flat surface as the fan exhaust is on the bottom of the unit.
