New MBA and external monitor - fan is going full speed

I just got a brand new MBA 13". When I connected via a DVI adapter to my Viewsonic 19" monitor the fan kicked into high gear and hasn't slowed since.
I am using it in dual-screen mode with both screens open, and I even have my MBA on an iLap stand to dissipate heat. The CPU temp is 77C.
Is there anything I can do to reduce the need for the fan to run full blast? Would switching to a VGA connection help? What about a different monitor (this one is 5 years old).
Thanks in advance!

There's a program in your applications folder called 'Activity Monitor' that you should check out. Sounds like there's a process maxing out your cpu when you plug in the monitor and that tool would show if that's true and what the process might be. You may have to select 'All Processes' at the top by the filter field and sort by cpu activity so the busiest comes to the top.
I have the 11 inch 1.6/4gb plugged in all day into a 24 inch, 1920x1200 lcd over dvi with both displays active at once and a 3x3 grid of spaces active (makes 18 virtual windows with the external plugged in.) and the fan is almost always at it's minimum (2000rpms) with the cpu temp just a little over where it would be at idle and the bottom only slightly warm. By the end of the day I'll have like a dozen term windows open, multiple word documents, excel, outlook, communicator, many many safari tabs/windows going, itunes,active vpn back home, 3 parallels vm's (win7, ubuntu, oracle 10g appliance), twitter, ical, apple mail, etc... and well you get the point, obviously this is a just a lowly netbook designed for light browsing! At this point the memory is maxed out and I'm using about 6GBs of swap space but the air is still silent and fast.

Fans Running at Full Speed

I've read elsewhere about "runaway applications" taking over the CPU maxing it out and causing the fan to run full speed constantly. It happened to me last night while I had nothing open except Safari and a couple of Dashboard widgets. I checked Activity Monitor and it labled DirectoryService as the culprit eating up all the processing power. I quit the application and the fan speed slowed almost immediately. I've heard of 3rd party apps causing these problems, but nothing within the OS. Any ideas about what caused DirectoryService to cause this? Running 10.5 now.

Is this only happening on first-boot? (As in you just recently upgraded?) If so, your system is caching everything in your Mac so it makes searching for files and etc. easier in Spotlight (it sounds like the Spotlight process). If not, then I guess it's simply a Leopard problem. DirectoryService is running fine on Tiger.

I believe the process related to Spotlight is "mds" and "mdworker" (md stands for metadata), not "DirectoryService". DirectoryService goes nuts for me when I plug in my iPod and copy music over. It never did this in Tiger. I wonder if it's trying to treat the iPod as an external drive with a broken directory tree or something.
What is causing DirectoryService to go crazy, I do not know. I am fairly certain it is not Spotlight.

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.

Viewer and External Monitor doesn't playback at same time

When watching clips in the viewer window, they playback fine. But on my external monitor, it only shows the first frame from when it's played. when I stop playback, the external monitor then shows the last frame the Viewer window is stopped on. How can I fix it so that the viewer and external monitor playback the clip at the same time?
At the moment we're digitizing footage with the Offline RT Photo JPEG codec set to 75% quality.
A few days ago we were digitizing footage at 35% quality and that footage plays back fine. We moved to 75% quality at the editor's request. A few days ago we had created a few sample 75% quality tests for the editor to view. I loaded those clips into Final Cut right now and they playback fine as well. So it's all of a sudden just these new clips created yesterday :S.

Yes.
Forgot to mention that the timeline plays all the footage back properly on both the canvas window and the external monitor. Sorry for not mentioning that sooner.
More discoveries! The playback 'freeze' only happens if I open a clip from the browser into the viewer. If I open a clip from the timeline into the viewer, it plays-back fine!

Satellite A100-646 and external monitor shows black screen

Hello to everybody,
I have a similar problem with A100-646 (bought in Italy). Laptop's LCD and external monitor shows black screen but system boots without other problem. When laptop is not used for a long time (half a year) it work for one week without any problem.
Unfortunately, there is no proper service in a place where I live. Perhaps, there is a problem with power supply.
Is there other idea? Does anybody have a service manual? ([email protected])

It is not easy to find shop where you can order original and new hardware components.
Best source for such parts is definitely eBay where you can buy used but well working components.
Upgrade? You must know that upgrade on mobile computers is not the same as on desktops. Cooling possibilities are not the best and each notebook model has optimized cooling system for original parts. So new graphic card can be more powerful and produce more heat and it is definitely not good for your notebook. So best thing you can do is to replace it with original part.

Viewing footage on desktop and external monitor at same time

Maybe i'm missing something, but is there any way to view footage simultaneously on your desktop monitor and your external broadcast monitor (via blackmagic output)?
Right now when I enable mercury transmit, the viewer within speedgrade goes to grey and I can only see the footage on the external monitor. This makes it impossible to draw custom shapes around objects (rather than just use the stock circle masks) which I use quite a bit...I would like to have the view on both monitors like I have in resolve.
If this isn't possible, is there a quick shortcut to toggle mercury transmit on and off without having to go into the settings menu?
Any help would be appreciated...I am enjoying a lot of the controls that are in speedgrade but there are some workflow hurdles that I need to get over in order to be able to use effectively in client sessions from time to time.
Thanks!

I waited expectantly and patiently for Adobe to enable Mercury Transmit in SG and to be able to make use of my BM card and external monitor.
O.K we got it in CC2014.1...but it is either Mercury Transmit or Dual Display!
I think this half-arsed solution is an absolute fail that we cant use desktop and an external monitor simultaneously.
Has anyone on the SG team actually been in a real world CC and Grade Suite?
At least we got consistency with the blue color scheme if not how Mercury Transmit works across the suite of apps.

Is anyone else extremely frustrated with the way that Lion handles external monitors now? My internet speed is ridiculously slow as a result.

I use only an external monitor as my set up will not allow me to use both my Macbook Pro monitor and external monitor efficiently at the same time. In the past, I would plug my MBP into into my external monitor with the lid closed, wake it up and then open the lid with no issues. It was kind of a pain in the rear but at least it worked. Now, opening the lid activates both the MBP and external monitors automatically instead of leaving the MBP monitor off.
This is an issue because, well, look at the speed test that results from simply closing my MBP lid:
Look at that MASSIVE drop in speed. I need to use just one monitor. Upon googling my problem, it seems to be widespread problem. At least there was a way to get around it before the screens autmatically changed...

Support today quoted Apple's engineers as saying it is "expected behaviour" in Lion for the MBP's internal display to reactivate upon opening the lid, even if you want to use only your external display. A new version of the clamshell mode-related knowledgebase article (replacing HT3131) is due shortly confirming this.
This is despite:
- obvious temperature-related benefits that were achievable (under Snow Leopard) by opening your MBP lid whilst continuing to output solely to, say, a 27" cinema display
- wifi connectivity benefits of having the lid open
- the waste of energy and inefficient use of graphics processing power in needlessly running two active screens (ie if running your MBP in clamshell mode would otherwise make it too hot and/or noisy or you need it open for wifi)
- negative longer-term impact on the battery and components from running the MBP hotter than it needs to be.
For any chance of getting the previous behaviour back, we need to ask Apple to change how Lion handles clamshell mode. Options may include changing Lion's expected behaviour or adding a user-selectable option within System Preferences. Now the situation has been clarified as intentional, user feedback on this issue has become all the more important.
http://www.apple.com/feedback/macosx.html
In the meantime, a low strength fridge magnet placed on the inside surface along the right hand edge (perhaps above the Kensington lock slot) may serve to convince a MBP that the lid is still closed. It's not something I'd recommend or do personally, but some others are reportedly finding this helpful in the immediate short term.

External Monitor will not display full view MS apps.

I have a HDMI monitor that was previously working fine. The other day I went to use Word and Excel and the applications would only appear in the lower toolbar. When I would select them they would not enlarge. They remained in a thumbnail view. My email and Internet work as expected. Any ideas what's causing this?

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.

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.

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.

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.

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
