Fan runs at full blast

Hi. I have a Sony Vaio PCV-RX660. I have the same problem when I load windows xp on it, but it is resolved by downloading a fan controller file from Sony. I contacted them, but they do not support anything other than xp. I also Googled 'sony vaio fan control unix', but got nothing relevant.
I tried 'rcacpid status' at the terminal and it says 'rcacpid: not found'
How do I enable acpi? Can't seem to get anything when Googling 'enable acpi solaris'.

Remove Growl, DiVXHTML and other DIVX software (use MPEG4Streamclip or Smartconverter or Wondershare Videoconverter for videos you need to convert for your own use, and not for giving to others unless you own the copyright for it). Update your Adobe Flash from http://www.adobe.com/
Shut down Parallels except when you need to use. Disable Citrix and your File Sharing for VPN or remote access for Citrix except for when you use remote access. Find out how to remove Peerguardian. The Mac has its own firewall which blocks all except ping attacks through Apple menu -> System Preferences -> File Sharing. Use a hardware router to block ping attacks.

My macbook pro is lagging, freezing, and fan runs at full blast. How can I fix it?

When I start up my 2010 Macbook Pro now, the fan starts running as soon as the spinning gear appears below the apple logo, the boot up is insanely slow, the mouse doesn't track well with my trackpad movements, and trying to open programs often leads to a non-responsive program with the pinwheel of death spinning for minutes at a time. I try to shut it down (takes approx. 20 min. now) and when the screen goes black, the fan continues full blast. After that I can boot up the computer and it runs normally, but the whole process takes about 50 minutes longer than it should, especially with a relatively new SSD (~ 8 months old). Has anyone seen anything like this before or does anyone know how to fix it?
It loads well enough in safe boot, and I've tried cutting out most of the apps that launch at startup with poor results. I've also tried resetting the SMC with equally poor results. I need help!
Here's my Etresoft report as well.

Fan running at full speed and all the time!

Hi,
I was wondering what could be the reason for my fan running on full speed at all times?
It is pretty annoying especially when I am in a quiet room. This just started happening this morning and I thought it was just going to stop but it didn't so I restarted my MacBook and shut it down also and still no luck.
Oh...
My battery meter only says 1:45 after I just took it off the charger when it said it was fully charged and I had the green light on my charger.
What could be the reasons for these two things?
Thanks,
Sam

I reset the PMU and the fan is still going at full blast right when the MacBook starts up.
Will I know that the PMU is reset or will it just fix the problem if it is?
Does anyone know a solution?
The computer is running fine but it's just the fan that is really loud and going at full speed and the battery life is extremely short for some reason.

Case Fan Running at Full Speed

I accidentally shorted the case fan circuitry on my HP motherboard (explanation below) and now the fan runs at full speed all the time. Other than the fact that is was a stupid thing to do, will it be a problem long-term and should I try to reset the fan speed switch?
(Long Version) It is hot around here these days and my computer fans seemed underpowered. I put a splitter on the case fan outlet on the motherboard and added a second fan in addition to the original fan. It all worked fine except the new fan seemed to run pretty slow. I wanted to get a voltage reading from the fan plug but I accidently touched the two sensors on my volt meter and the computer immediately shut down. It started up and worked fine except the throttle was no longer working and the fans were running at full speed. This also explained why the second fan was running slowly before when they were both being throttled.
I guess in the end I got my wish to have my fans running at full power, I just wanted to see if there will be any future problems leaving it this way.
This question was solved.

Hello design_guy,
You should not have any problems with the fans running at full speed other than the fact you may decrease the life cycle of the fan.
You may want to install some software on the computer that will allow you to adjust the fan speed from the computer which may help you prolong the life of the fans and give you a little control over them.
Something like SpeedFan should do the trick.

My iMac G5 Fans run at full speed when using regular everyday applications.

When using just normal everyday applications such as using about 30 min of Safari to surf the web or maybe something else, my fans run at full speed. I have just got a new logic board replacing my old faulty one. How can I fix the fan problem?
Thanks!

Hi again Miriam,
With more news for you and iMacG5 on the fans go crazy. I just got back my computer from the repair center. After more than a week under observation, the technician told me that they just couldn't replicate the problem. They had the computer running non-stop during all this time, not even allowingit to go to sleeo mode and nothing.
The CPU fan never went beyond 2300 rpm (or so) and never went to sleep mode on and off by itself. Furthermore, they ran all possible tests and everything comes back as OK.
Right now I have a movie running on the background, together with a photo processing software open and other smaller processes and the CPU fan is running at 4361 rpm !!! the temp of the CPU is 66.3 Celsius.
Any thoughts??? It's really making me crazy because the computer was neverlike this and now it sounds like a hair dryer. I emphasized with them the fact that this just started after they changed the logic board and as coincidence after Ioaded the security update 2006_04. The technician told me it may be software related. If the computer doesn't go to sleep by itself, then he recommended to reload the operating system.
Any comments appreciated.

Fans run at full speed

As in subject, my brand new iMac Aluminium 20" 2GHz has a problem: fans run at full speed...
After reset of PRAM or SMC, fans start slowly (1200rpm) but rise ti 3500rpm after few minutes and they don't change until a new restore of SMC.
cpu 3-4%,
no apllication opened,
nothing in dashboard.
What's happen?? I've never had a problem with my mac!
PS: sorry for my bad english, I'm italian!

Hi, just an update -
I ran the Apple Hardware Test on startup, and it returned this hardware error: 4SNS/1/40000000:TpoP
I brought my machine to the Apple Store where I bought it and they ran their diagnostics and said there was nothing wrong. So when I picked it up we booted it up in the store and the fan was about 1200rpm, no problem. We ran the Apple Hardware Test in the store and it didn't give the same hardware error that I'd had before.
So, I didn't really have any ammunition to press them any further on it and for the last week it's been fine. I had the fan race on me again last night but I hope it was an isolated incident.
As for downgrading to OSX 10.4, I'd consider it but I don't feel that I should have to do that to make my hardware perform correctly.
Re. smcFanControl, I thought the purpose of that is to make the fans run faster/more often, but if anyone's used it to stop them from running too fast/too often I'd be glad to hear from you.
Maybe the 10.5.2 version of the OS will take care of this problem, if indeed a problem exists.

Very noisy iMac, fans running at full speed even when performing smal tasks

I have a 2009 21 iMac, recently the computer became very noisy with the fans running at full speed all the time even when checking the email or just using Safari. I don't do anything crazy like 3d renderings so I don't know why the fans wont stop. I recently cleaned it but this didn't seem to solve the problem.
Anyone knows what's the problem and how can I fix it?
Thanks

TS1433 Fans run at full speed after computer turns on

Fans run at full speed after computer turns on, and a lot of times while i'm working they suddenly start blowing and won't stop. Tried the reset SMC, nothing happens. Also the unplug powercord-method does nothing.
Anyone?

Exactly what method did you use to reset the SMC, every Mac has different methods and I want to ensure you used the method for an Intel based Imac. The correct instructions are in the iMac SMC and PRAM reset link. Do the SMC reset at least 2X!

Macbook May 2010 edition exhaust fan runs at full speed

Bought a new Macbook around February 2011. Yesterday all of a sudden while watching Netflix, the exhaust fan started running at full speed (Approximately 6200 RPM). I thought the machine was overheating. So I immediately shut it down and let it cool. But I noticed the machine was barely warm.
When I started it up again, it started making the same noise with the exhaust fan running at full speed. I installed SMCFanControl and I see that the CPU is barely warm - 35-37C and yet the fan is running at full speed. I looked at the CPU/HDD usage and there is barely ANY usage (~90% idle). Nothing out of the ordinary. So it definitely doesn't seem to be a heating issue.
In order to troubleshoot this I have done the following:
1. Installed latest upgrade - Snow Leopard 10.6.7
2. Reset SMC
3. Reset the PRAM
4. Tried booting from the install DVD. There as well it exhibits the same issue.
Neither of these steps have helped me with my situation. I would really hate to go to the apple store as its always crowded and would end up wasting time. Are there any other steps I could try?
Update: I tried running the Apple Hardware Test from the DVD. This is the error code that I got: 4SNS/1/40000001: TN1D- -1.000
Can someone please tell me what this means?

I don't know what that code means for sure, but it sounds like one of the temperature sensors may have died, so the fans just run at full to cool.
I would take it to the apple store.

G5 fans - runs at full speed

One of my MACs (G5 2.0DP) can't slow down - the fans runs at full speed all the time (OSX 10.3.9) - hardware test - PMU - disconnect powersupply - exit single user mode - I think I did all that's in the "book" - but the fans are still running at full speed - all the time.
any ideas?

Hello,
I am not sure if you have the same issue, but I might be worth it for you to read the archive:
http://discussions.apple.com/thread.jspa?threadID=561296&start=0&tstart=0
And here is the end of my story:
Regarding my issue with the fan fan full force, yes it was resolved... but not without fighting for it!
Fortunately the machine was still under warranty, and I left it with Apple care during an oversea trip in August. End of August I picked it up suppositely fixed and after a few hours of work I noticed the same symptoms were still there! You can be sure I made it clear to Apple service I was not happy. I left the machine again for a week and 1/2 and picked it up again. They told me they replace the logic board. Again a few hours of work of testing and this time I could repeatidly hang up the machine. Back to Apple, I told them I didn't want to pick it up until they REALLY tested it! This time they replace the logic borad again, the power supply and something else?...
Anyway since then the machine works just like it did before : great, no hardware system related issues.
Unfortunately I cannot tell you for sure what was the problem: logic board? CPUs? power supply?... and I could not get the information from Apple care, especially I would have been interested in the specific procedure they follow to fix my problem... but for some reasons they don't want to share this information...
I hope your machine is still under warranty... other wise you'll have to weigh the pros and cons to have it fixed, especially if they replace the logic board ($900 I believe) or any other main components...
I hope this help,
Good luck,
David

G500 fan running at full speed for no apparent reason

I have G500 that worked perfectly for a year now. My operating system is Windows 7 Professional. Yesterday the fan started working full speed while the laptop was idle, I wasn't using it and the software that was running in the background were the usual programs I have been running for the last year. First step was to check the temperature of course, which is normal. Then I checked if anything weird is running in the background and creating high cpu usage, but that was not the case either. What I noticed though was that fanspeed is not recognising the fans or counting their speed. Is it a problem on the hardware? It is really annoying. The speed also fluctuates very often, reminds me of how it should work while gaming and definately not when idle.
Thanks

Hi Zoe,
Welcome to Lenovo Community!
As per the query we understood that you are facing fan issue in your G500 laptop.

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.

Mac Fan runs at full Speed from start, even in standby mode!

Hi Folks
Since this night my iMac's fan (summer 2012 model) runs at full speed from the beginning of powering it on. It even runs at full speed when I put the iMac to sleep!
So far I tried to reset the SMC three times, noo effect at all. I checked also the activity log, no processes or other activities are causing this. I read about defect HDD sensors, could that be the problem?
Any ideas how to fix or at least control this issue???
Thank you all for your help!
Matt
PS: That's a pretty annoying sound I'm hearing here, I feel like on the roof top of the Hancock Building at wind speed 200!

I have tried the SMC reset as instructed and the fan is running normally. It is a bit of an intermittent problem so I will monitor the performance of the computer over the coming weeks. If it persists, I will take it in to a service centre while it remains under warranty.
I guess the "cure" I had stumbled across by accident was nothing to do with turning the computer upside down, it was because I was unknowingly performing an SMC reset. The reason I turned the computer upside down was to find the serial number on the base of the stand so I could report the fault to Apple. Of course, when I plugged it back in to contact the support line, it worked fine.
Once again, thanks for your help.

IMac CPU fan speed at full blast.

I have a 20" iMac (A1224) and when you srtat it, the CPU fan goes full blast and never stops.
SMCFanControl reports the CPU fan at 3900 RPMs (full blast) but what is it trying to cool? The temperature is 27 degrees celsius (80° F), Activity Monitor says 93% of my CPU is idle. I've done all the normal SMC/PRAM stuff and it seems that my CPU temps is just fine. Something needs to be replaced.

HT3964 Fans running on full speed constantly

Hi.
I've had this problem for a while now and I'm not sure what else to do, short of taking it to an Apple authorised dealer to be looked at. The fan on my iMac Intel 24" has been running at full speed straight from when I turn the machine on. I have looked at numerous articles on the problem and have just tried the one on apple support for resetting the SMC but it still has had no effect.
Has anyone else had this problem and know how to solve it?
Thanks!

Contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine.
