Problem with fan

Gday all, Not a major problem i dont think but, the north bridge fan on my board just started having speed fluctuations to almost stopping. Atm its running between 7100 to 5200 and the mb temps at 42c, and doesnt sound too good either. Im guessing it s on its way out. Is it difficult to fix, replace? any help would be grand...thanks in advance!

i gave it a good clean n seems to have stablised, sounds a tad rattlely though. Ill buy a spare just in case, thanks for the reply

MSI R7870-2GD5T/OC problems with fans

Greetings.
I just bought this card and got some problems with fans: when temperature of GPU rises above 52-55 degrees fans start spining at maximum speed.
Tried fix that using MSI afterburner/Catalyst control center - no effect, fan speed showed as I set up, but the tachometer shows 4400 rev / min, which is confirmed by the characteristic sound.
I hope that there is a fix for this beacause i cant RMA my videocard, I accidentaly lost the box, and since I paid 190€ i would like to have some support from MSI.
Thanks.
Edit: Noticed now that here nobody work for MSI, well an help would be great anyway

the Original box doesn't matter if its gone as MSI don't like them in original box as they won't return the card in it.
as long as you have the original receipt from your purchase and the Graphics card your all good....
as for the problem your having it will be a leak current on a faulty safety catch diode (201) as they got a bad batch a while back that when it gets hot it opens the fan circuit to maximum as it thinks the card is overheating. (either remove it carefully (as long as you do not damage the card your warranty is still intact as the removal of that component is what MSI suggested when the issue first showed up) or RMA the card)

One more time - problems with fans

I realize this is but one of hundreds or possibly thousands of cases of Mac users being plagued by fan noise problems, but to me it has been a long and extremely frustrating saga. I have been a Mac user since the very beginning, through different versions of Macs and iMacs, and this is the first time I ever refer to a Macintosh as a "piece of junk."
I bought my iMac G5 in August 2005, a 20-inch ALS with 250 GB hard drive and 512 MB RAM. It worked perfectly until January this year, when all of sudden it shut down by itself. Freaked me out completely. Turned out to be power supply problem (EMC 2056) which Apple never informed me about.
I brought it to a repair shop that fixed the intermittent shut-down problem. I also added 1GB memory. But then the fans started to go berserk. Before the power supply problem, I only heard the fans whenever I used a large program like Photoshop. For the most part, it was a very quiet machine. After the power supply was replaced, within minutes of turning the iMac on, I could hear the fans spinning faster and faster, stabilizing at around 4400 rpm and did not stop spinning until I put the iMac to sleep or turned it off, regardless of CPU usage or software being used.
I checked the discussions at this forum (over 500 posts, no real answer) and did every "voodoo trick" suggested: I reset the SMU dozens of time, cleaned the inside of the iMac and around the fan area, did apple hardware test (everything was fine), monitored temperature and activity with XRG (average CPU at 160F, hard drive at 113F), cleaned out caches, tested for corrupt preferences, re-installed the original OS 10.4 (which only made the fans louder), upgraded it back to OS 10.4.9. I also removed the additional 1 GB memory, thinking it might be a bad piece. It didn't help.
Finally, I requested fan replacement from Apple and got them. I installed them last Sunday and now the problem is even worse! Within SECONDS of turning it on, the CPU T- Dio soars to around 170F, even while the machine is still stone cold to the touch. The hard drive temperature now averages at 117F, CPU fan is never below 4000 rpm (4400 rpm 98% of the time), even at 5-8% CPU usage.
The fans themselves are much quieter because they're brand new. But you can still hear the hums and whirs and it drives me nuts. More seriously, my iMac is now narcoleptic. If I use it too long (a few hours on a stretch) it will put itself to sleep, apparently because it thinks it is overheated. And when I use Photoshop or Illustrator, the awake time is even shorter. Depending on the outside temperature, at the most I can only use them for about an hour at a time. Two days ago we had heat wave, and even with the air conditioner running full blast in my study, the iMac kept falling asleep within minutes of using Illustrator.
Right now I am using TextEdit and no other program is running. Uptime is 59 minutes, average CPU 9.6%. CPU T-Dio is at 168.8F, hard drive 117.5F, CPU fan at 4400 rpm. I am out of ideas and before I do something drastic to this machine, if anyone knows what's going on with my iMac (I know every case is different), please help!

I do not have the solution... but the same problem with a nice iMac G5 purchased in July 2005.
My Mac operated very silently untill 6 month ago;problem MAY ( I am not sure) have started when I upgraded to 10.4.10 ; even with few applications and low CPU usage (80% or more inactive), it seems that I have the following regrettable chain of events;
==> the CPU temperature is quite high ( 60°c to 72°c most of the time, ie 140-160 °F)
==> resulting in fan turning at high speed ( 2.000 for CPU and system, 2500 for HD), and changing speed all the time
==> resulting in a noisy computer
I am SURE this was not the case 6 month ago, and I suspect it is linked to my upgrade to 10.4.10.
I did all sorts of reinstall, authorization repair, SMU reset, fan clean-up with no sucess.

Problem with fan speed on FM2-A75-P33

I have a problem with setting a lower cpu fan speed on my motherboard (Win7 64).
It always runs on high speed, and I can not decrease it. When I set values for min speed in ClickBios II (or manually in Bios before booting) to 0%, and desired temperature on some higher amount (60C), nothing happens. It always run on same high rpm, regardless any change of values. What can I do? Same thing with sys fan.
Live Bios says that I have latest version of BIOS and drivers.
thanks

That is odd. Only thing I can think of is maybe a conflict in settings between Click Bios and actual BIOS. One of the reasons I never use those programs. I'm not sure what to tell you, except that the fan speed settings on my board have all worked properly using standard BIOS settings.
If I was having issues I'd uninstall click BIOS and see if the issue continues. At least then you would know it's something else.

HP Probook 6540b problem with fan speed and sound card

Hi.
Sorry for my English.
I have installed Arch 32bit on probook 6540b (it has core i5 processor). Cpufrequtils works well - with governor set on ondemand frequency is adjusting correctly but fun is running max speed all the time. I have tried to configure lm_sensors but it doesn`t detect any sensors. Also fun folder in acpi is empty. It would be great if You could help me.
Thanks for any advice.
...ergh
Fan sometimes works slow so maybe its overheating problem.
But
I have another problem with sound on this laptop. I have IDT 92HD75B3X5 sound chip and snd-hda-intel module loaded for it but it doesn`t make any sound. In Amarok it looks like something is playing because progress bar is moving. I have tried everything from arch wiki and other sources but nothing works. Maybe You can help?
Thanks

Hi. Yes. I also tried all tricks with model etc. and nothing. Now I have installed oss and have some progress. I have sound on pcm2 when I run osstest, no sound on pcm1 (but it looks in test like it plays something) and input/output errors from pcm3 to pcm7. I have oss output in multimedia in kde and when I run test I can see moving strips or something (I dont know the word for it ) in ossxmix but I hear nothing. I I tried all configurations in ossxmix and nothing.

Problem with Fan Running

I'm having problems with my new(ish) iMac. This problem is a bit involved so please bear with me.
While adding a torrent to my downloading program azureus, my computer froze. It would not allow me to shut down or do anything. So I unplugged the machine and waited awhile and attempted to restart. To my horror, it would not start up. I then unplugged the power cord in the back and held the power button while plugging the cord back in and then released and pressed the power button again. My computer turned back on, hooray, BUT, now the fan is running very loudly and has not stopped. I restarted, shut down and left it alone, and now I'm very confused. Any suggestions?
thanks
-Lisa

Hi Lisa!
You should go to this link: http://docs.info.apple.com/article.html?artnum=301733 - you've basically reset the SMU on your machine but read the article and follow carefully. You should go ahead and reset the PRAM, which is also covered in the article.

Next time this happens, just hold the off button for a few extra seconds and your Mac will shut down.

Problem with fan Trap.

Hi all,
I am having a problem resolving fan trap.
I am having a universe build over a MY SQL database.
The universe totaly consists of 4 tables and are related in the following way.
"A one to many B one to many C many to one D"
There are many 1-may joins between A and B and also between B and C.
There are measures and dimensions in A, B. And in C there are only measureas and 1 dimension.
When I pull the objects from all the three tables (A,B and C) there is a fan trap occuring and the values are getting inflated.
So I created an alias for B and defined a context for A, B and B alias and A,B and C. I have also checked the option of "Multiple SQL statements for different contexts."
But then I am trying to build a report in WebI and pulling the objects from both the unvierses there are 2 queries being generated and in the report, I am not able to pull the objects from different contexts into the same table.
If I select an object that is in context-1 the objects that are defined in context-2 are being dissabled and vise-versa.

You can set this behaviour in the universe parameters under SQL->Multiple paths->Allow seleciton of mutliple contexts .
Still since you are solving a fan trap you should keep this option clear.
A solution is to fetch the data from 2 different contents using 2 different webi queries and then use the Merge dimensions functionality in the report itself to join the results.

STratos

Dual G5 late 2004. Some problems with fan and freeze and now can't start

I just purchased a late 2004 Dual 2.5 Gig, with PCI-x and 1 gig ethernet. 1 Gig of what I presume to be factory ram and blue toothe. Connected to a new 23" Apple display.
The problems I have been having pale to where I stand now. I am stuck and can't move forward. At this point, the computer is off. When I try to turn it on, it does little to nothing and gradually the fan speed increases until the computer sounds like it wants to take off. The screen either stays dark, or sometimes I see the ? briefly, and then the grey screen with logo and that is where it stops. Currently I can't get past a lot of fan noise??
Can I get this thing started?? I have tried both starting from CD and hard drive. No luck.
This whole mess started yesterday and has continually gotten worse. Those details I can get into if needed, but for now, what can I do to see the screen and start over.
I just bought the machine, and I was doing a clean install that was acting funny. Hard drive sleep mode would cause the machine to not wake up. Specifically it was the monitor that would not wake up. The keyboard and the computer would still respond when I adjusted the volume. The screen was black.
I narrowed the problem to drive sleep, or monitor sleep by using the energy saver preferences. Just the monitor sleeping wasn't the probem. The computer would wake up. But if the hard drive went to sleep, then I could never get the screen back and the computer acted dormant. The only thing I could get was the volume sound from the computer and lights on the keyboard.
I ran Techtool Pro 4.1.2 ( i think ) and it reported possibe problems on the hard drive with the volume. I made the changes hoping that would fix the problem? No.
I decided to flush it all and start over with the install cd, make sure firmware was good, reformat the drive, and then install the System. But instead, I got caught is this loop of death that I can't get out of.
It had a kernal panic the first day I turned it on, but that was the last one. (dark screen with white message) The computer ran rather sluggish at times. I was shocked at times. Very slow finder response.
So? Suggestions? I have searched Apple support and tried anything I can think of. This is my first G5, but I have had some exposure to OSX beginning around 10.2. I am at my wits end and would greatly appreciate some input. For now I have to get some sleep.
Is my battery bad? It just won't start?
Thank you for any help you can provide, or links to articles!!

Hi Lawson, and a Warm Welcome to the Power Mac G5 Forum!
You could try a PMU/SMU reset
http://docs.info.apple.com/article.html?artnum=300341
Use the second procedure if you have a button as shown in the photo - use the first method if you don't. You may not have to remove the intake fan assembly to get at the button. Observe static precautions and make sure to press the button once only.
Then try to start up on the CD/DVD.
If it fires up ok you could then proceed with the 10.4 install as before, and then combo update to 10.4.8
http://www.apple.com/support/downloads/macosx1048comboupdateppc.html
I would connect only a display, wired keyboard and mouse to start with - and disable any of the sleep, etc. Options in Energy Saver.
You may wish to use the Disk Utility on the 10.4 retail disc(under Utilities in the menu) to Erase and zero(select Security Options) the drive before the install.
The kernel panic and other problems could have been caused by a corrupted system on the boot drive, or by hardware problems, such as RAM, video card, battery, etc. Some of the hardware stuff is linked-to further down the post here
http://discussions.apple.com/thread.jspa?messageID=3084827&#3084827
However, try the PMU/SMU reset and erase/install first, and post again with details if you still have problems.

Problem with fan, temperature and battery after the restore from the stop (Macbook pro 15)

From a couple of weeks my macbook pro (15" 2.4 Ghz i7 4gb OS X 10.7.4) has this problem: when i close the screen it goes to stop and when i open it goes out the stop normaly but the fan and the temperature increase and the battery last nothing. So i reboot the mac and everithings go to normal way and also battery time increase in comparison with before...

I've found that samsung kies wifi started at the login and that the app used 91% of my cpu and filled up my ram so i went to: system preference > users and groups > login's elements > and i deleted the app from the list.

Problem with fan noise and battery on g510

I bought an new lenovo g510 ( core i5 4200m and amd r5-m230 ) from 3 days
and notice that fan has a noise most of the time and when i check the battery wear level on hwmonitor it is has 1 % wear level so why i got these problem and my laptop is bought from just 3 days !!!!!!

Hey. Really sorry for late answer. i got same model (but i7 , r7 m265 )
For the fan noise ; check out gpu and cpu temperatures . clean the fan dust with power manager program. and update drivers.
for the battery , %1 wear is nothing . only affects 1-2 mins . battery has internal smbus battery fuel gauge and it automatically calibrates battery full charge capacity. but you can manual calibrate fcc with power manager. we are very lucky because on some hp ,samsung etc laptops , battery comes with %10 wearage (like my old laptop).
you post this message 6 months ago. if your battery wear is >%15 now , send battery to service. they will replace a new battery. if battery wear <%10 , your battery is normal

Waiting for local disks??? problems with fans and starting up

Hello and please help me. My late 03 Mac isn't loading up. It gets past the grey bit and onto the loading part where everythings going fine until it stops on 'waitng for local disks' the fans then start to go nuts and I have to switch it off manually cos nothing is responding and I fear it may blow up. There's no disks in the drive and I've tried pressing the pmu button, disconnecting the wires and rebooting it from the original disk (when I do the latter it simply loads back up and stops at, yep you guessed it...waiting for local disks)
Any suggestions before I take it into an apple store?

Hi! Try restarting with the mouse button down to eject the disc. After you get the disc out if it still won't boot hold the option key down until the disk comes up and you can select the correct one to start from. All else fails boot from the install disc ("c" key down at startup with the disc inserted) and run the repair disk function of disk utility as per THIS. Tom

Problem with HP pavillion dv7 giving message (a problem with the internal fan enter = shutdown

HP Pavillion DV7 notebook PC
Windows 7 64
intel I5
6 gig memory
service pack 1
I am trying to identify a problem with my HP Pavillion dv7 laptop
Several months ago it started getting hot and showing messages about problems with the internal fan and battery. It would say enter = shutdown and shut off. I suspected a bad battery so I checked it without it just plugging it in with the power cable. It seemed to work better so I assumed that was the problem.
I ordered a new battery and it worked for a while. The problem came back and is getting worse. I can run it without the battery for a while but it gets got and shows the same message.
I read on here that flashing and updating the bios worked for some but the latest update gives me an error IHISI not support BIOS then Insyde flash not supported.
any help would be great this PC has a lot of info on it and I dont think it is a lost cause

Problems with G5 fans coming on...

I have a very early Power Mac Dual 2GHz PowerPC G5 running OSX 10.4.11 which has started having strange problems... For apparantly no reason all the fans come on and stay on - this can sometimes be resolved with a restart, sometimes not, in which case I need to shut the machine down - after which it will sometimes not reboot the first time (gets as far a blue screen then hangs) - I then need to unplug it from the mains for 10 mins or so, afer which it will start up normally.
Looking into the problem I have discovered this message in the system log every time it happens:
Jan 10 22:01:19 teknomage kernel[0]: AppleMaxim6690::readI2C error (0xE00002C2) I2CAddr = 0x98, subAddr = 0x01
Jan 10 22:01:19 teknomage kernel[0]: AppleMaxim6690::getExternalTemp read temp failed!
I have also started running a temperature & hardware monitor to try and get to the bottom of this and have discovered that all my temperatures show a flatline when the fault is about to occur. If I then restart the machine, all fans will be running. If the machine starts up with all fans running. On one occasion, CPU A showed a flatline temperature of -6.1 degrees for several hours (with the machine working just fine!) and the machine restarted into all fans running mode after this.
I have tried both replacing the battery and resetting the PMU - which appeared to fix the fault for a few days, it then recurred.
The machine also will not sleep properly - in that it won't always wake from sleep and needs a power off and reboot - which sometimes occurs with all fans running.
Apart from that the machine works fine - all my software works etc even when all fans are running.
Any ideas as to the cause? I've not changed the hardware (except to replace the battrery when the fault first started) or software for over a year. Is it case of a failing logic board or could it be something else? Any ideas on how to resolve this?
Is there any problem in running the machine when the temperature monitor is showing flatline temperatures for all sensors - or is there a lower level system that will protect the machine should temperatures get too high (maybe by switching to all fans running?)

An update to my G5 fans problem - the problem got worse, with trouble booting the machine at all. It would sometimes take up to half a dozen attempts to get a chime and then a boot :-( Sometimes all the fans would come on after a few minutes, sometimes not at all day. Sleep mode stopped working completely. As the problem was getting worse and worse, I gave in a bought another, refurbished machine identical to mine, swapped over my disks, extra memory & SCSI card and everything on tha machine works just fine :-)
I may try to further diagnose the problem with the old machine later on.

I'm wondering if anyone else has had problems with their imac fans being extremely loud when running at slow speeds? When the computer heats up enough for the fans to run at higher speeds they quiet down. New HD fan was just installed.

I have an imac that I've had for a couple years. The fans have always been loud when running at the slower speeds. When the computer heats up enough for the fans to run at a higher speed the fans quiet down. I had installed SMC fan control after multiple attempts with Apple to get the fan issue resolved. That seemed to keep the fans quiet enough. I've never had a problem with overheating. Recently the fans were becoming loud again even running at the slightly higher speeds so I took it to my local Apple store and they replaced the hard drive fan. I got it back and it's now as loud or louder than ever!! And, now SMC fan control won't "stick." The fans will speed up, but then gradually go back to the lower "loud" levels. I'm at a loss as to what to do next.

Thanks jared,
I'm still dealing with this issue through Apple. Some time after I posted this, I contacted Apple again. They did start a case up for me, as I was experiencing the same behavior on two different machines, with two different versions of Windows.
So far it remains unsolved. I've logged iClouds for Windows on my desktop, which is brand new, then logged for awhile after completely uninstalling Norton Security Suite, depending on the Microsoft security for some time, and finally logged after I uninstalled iCloud for Windows, restarted, installed a clean download, and connected using a completely different test account, which Apple set up for me. None of this made any difference. Looking at the logs, it seems every 10 minutes, iCloudServices.exe creates a new TCP connection to confirm I'm using less than 5GB on iCloud, (which I am by a good margin, using less than 2GB), it seems this connection is not closed, and when the next iteration rolls around 10 minutes later, a new TCP connection is created. I come very close to having 6 TCP connections created per hour, until I restart my computer. This works out to... 6 x 24 = 144/day.
Perhaps the article you posted will shed some further light on this. I'm thinking seeing the state of the connection through netstats, at the least, could help.
For the last week, I've been putting a hold on further logging, as Apple wants me to create a new user account on one of my computers, install iCloud for Windows there, and log it running in the other account. This however basically means I cannot use my computer for a fair number of hours, and I've been busy enough with work the past week that I haven't the time or energy to afford to set this up and run it. I've had need of my computers too much for the past week.
