Winbindd causing new CPU (fan runs to 6000rpm)

over the last few days, i've been hearing my macbook fan spin up high when I'm not even using it. Each time, i've found an instance of WINBINDD taking 90%+ of the CPU time in Activity Monitor. Stopping the process clears it until the next day.
I've noticed it only happens at home. When I'm at work it only shares a private network with one only macbook and doesn't do this. My home network does have some windows stuff on it, i understand winbindd is part of samba?
Anybody have any ideas? Thanks

I do have a DC on my network. In fact, I just migrated to a new machine and transferred the DC roles. I didn't notice the issue before that. Where are these SMB settings you suggested? Maybe something's still pointing to the old machine instead of using the new one ...

I suspect you have hardware problem with a fan sensor. Doing a software install will not help the machine needs to be taken in for service. If you run Apple Hardware Test in Extended Mode it should reveal the error code. If it does not then run AHT an additional 2-3 times to be sure in Extended Mode. Each pass will take about 30-60 minutes.

CPU fan running full speed after 15 minutes

My 3 month old iMac 24" has just started having fan problems.
Before I went away on a training course, it was working fine. Left it switched off at the outlet for 3 days, now the CPU fan runs full speed after the iMac has been switched on for 15 to 20 minutes.
CPU temp is 24C, CPU heatsink is 28C. Ambient is 17C. CPU fan is 3600rpm. Other fans are normal.
CPU usage is less that 10%. Only Safari is running.
I've tried resetting the SMC - left all plugs disconnected for 15 minutes, reconnected mains power for 15 minutes, reconnected USB, then switched on.
Still the same - OK for 15 minutes, then CPU fan runs full speed.
Anything else that I can try?

I tried again, following your instructions exactly. It seemed to work, running normally for about an hour.
I left all the USB devices unplugged, except for the keyboard and mouse.
I then shut the iMac down, but left the mains power turned on at the wall. When I switched it on again 2 hours later, all was OK for 15 minutes, then the CPU fan ran at full speed.
Shutting down for a few seconds fixes it for another 15 minutes.
I'm wondering if it's a software problem, although I haven't loaded any apps recently, apart from a few monitoring programs since this problem appeared.
Last night I left it running the extended hardware test for a couple of hours, and the fans were fine.
One thing that I noticed yesterday was that the "GPU" temperature readings in iStat were all missing (just "-" displayed) for a couple of seconds when I clicked on Dashboard. Is there a way to keep iStat open while I'm using the iMac?
I think I'll try booting XP and see what happens.

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!

Computer won't load Windows after installing new CPU fan

My wife's computer's CPU fan quit working so she bought a new one and installed it just now. She turned the compuer on and it says "Windows failed to Start. A recent hardware or software change might be the cause."If Windows files have been damaged or configured incorrectly, start up repair can help diagnose and repair the problem. If power was interrupted during start up, close Windows normally." The choses are "Launch repair" or "Start Windows normally." When she chooses either of those, the computer shuts down. If she tries to perform a system recovery, the computer shuts down. She tried loading BIOS defaults (as was suggested on other websites), it had no affect.

Hello anthonydobmann,
You’re having a problem with the computer not booting after replacing the cooling fan.
First I’d make sure that the cable did not come disconnected from the hard drive.
Boot the computer into diagnostics by tapping F2 at startup and run the hard disk test.
If diagnostics passes try to boot the computer into safe mode by tapping F8 at startup.
If you’re able to load into windows you might have to run the recovery.
Here are some links to run a recovery.

Windows 7 recovery
Let me know how everything goes.

CPU Fan running fast

Hey Guys!
I've some Problems with my IMAC 27" early 2011.
The CPU fan is running at about 3800 RPM even though, the sensors say, the CPU is pretty cold.
Here the Temps that iStat gives me:
HD: 41° C
CPU: 33° C
GPU: 43° C
MEM: 38° C
Optical: 38° C
CPU Usage: User 0-2 %, System 0%, Nice 0%, Idle: 98-100%
The problem occours some 10-15 minutes after I've switched on the IMAC and it stays, even if I restart the IMAC for at least 2 hours. Once the fan is returning to it's normal RPM (after 2 hours or more, mostly after being in Standby), i can work for several days and it doesn't return, unless the IMAC is switched off and on again. I think, the IMAC slows down, when it has this problem. Especially scrolling in Safari is extremely slow then. Sometimes it even stops!
Things I tried to correct this:
SMC-Reset --> Didn't succeed.
Start in 'Safe Mode' --> Well it's running in save mode right now and sounds like a vacuum-cleaner.
Disconnect all externals --> Nothing
Deactivate Time-Machine --> Nothing
P-Ram-Reset (?) --> Nothing
New User Account --> Nothing
I think the problem first started to be there some days after installing Lion. By the way: My MBP 15" Late 2008 runs great with the same stuff on it.
Anybody got any ideas?
Thanks a lot & greetings from Germany!!!

I've got the opposite problem, my AMD CPU is running around 55C and the fan hardly ever exceeds 1200 rpm most of the time its running around 950rpm. I think the 48C to 65C is running on the edge of to hot in my opinion, I like to stay around 35C-40C. Motherboard, video card and hard drive all stay in the 30C range. I tried to speed the fan up with SpeedFan program but it can not interface.
I hope someone can give us a answer, I checked the UEFI and could not find any setting allowing controlling fan speeds on my ENVY 700-200z/AMD A10 cpu.

IMac cpu fan running at full rpm

hi all
A few days ago my cpu fan started running flat out. I have done the smc or whatever it is caled reset thing where you unplug the cored ect.
I have done the hardware test with no bad results.
I have checked activity monitor for cpu usage and there is nothing unusual there, so I can only guess that the cpu temp censor is faulty.
I should also add that this machine has been running non stop since mid 2007 , with the exception of the odd blackout and restart, thats pretty amazing i think.
maybe its time has finally come ;(
any clues ??
thanks

SMC is firmware and OS X is software, which has nothing to do. Furthermore, you are using a very old iMac, so SMC should not have been updated with OS X 10.10.2.
If you have tried a SMC reset and it did not work, run Apple Hardware Test (make sure you choose an extended test) to see if there is any problem with a temperature sensor or anything like this -> Using Apple Hardware Test - Apple Support
Note that you may need the DVDs that came with your Mac in order to run it. If you get an error at the end of the test, please copy it here.

Edge 130 overheats and shuts down, but CPU fan runs at low speed

Hi! I am having a problem with my Edge E130, running un Windows 8.1 64-bit. When running under high load the laptop will at times overheat so much that the system does a hard shutdown - it simply powers off. I installed Speedfan - it shows the CPU at above 90 degrees celsius. The weird thing is that the CPU fan is not running at full speed. I do not know why. Is there a way to fix this? The fan should at least run at full speed. Thanks in advance!

Thank you for the reply! I can't seem to find a black and white sticker. There is a sticker which is black with light grey text. Is it one of these two numbers? label P/N 0B07208CT1 label P/N 0B95210 I am not using any fan control software. Also, my BIOS version is the latest available from Lenovos support site. (when I update the BIOS last time, the fan was running at very high RPMs for a while during the install. So it seems it would be possible for it to run faster)

Fans run at 6000RPM constantly and Function keys are misassigned

OK here's the story: I've got a 17" Core 2 Duo MBP that I replaced the top case (keeping the original keyboard) and hard drive in. Now the fans run at a constant 6000 RPM despite what I have Fan Control tell them to do. In addition, the function keys are misassigned - the keyboard is labeled with volume control on f3-f6 and keyboard brightness at f8-f10, but f10-f12 actually control volume and f5 and f6 control the screen brightness (it appears it still thinks I have the 110 key USB KB plugged in since it's following that layout).
I've tried resetting the SMC and applying the SMC firmware update with no luck (the firmware updater tells me I don't need it and I can't find a way to force it). There are no processes hogging CPU, and I've disabled indexing just to be sure. The fans will run at 2700 or so for the first few minutes, but as soon as the temp hits about 104F they go max and don't slow down until I shut it down or put it to sleep. I'm using a drive image from a black MacBook so I suspect my OS install is confused about what hardware is actually present, but before I do a clean wipe and restore I'd like to know if anyone has any other ideas. Thanks!

Welcome to Apple Discussions
The fans run at maximum if either a) the cable has been left off the temperature sensor or b) the sensor is bust - I'd guess you didn't remake the connection or it's come off during re-assembly.
+a drive image from a black MacBook+
That's a mistake, you should only install and use the OS that came on the install DVD with your MacBook Pro, there are significant differences in the software ...

CPU Fan running really fast even at low temperature.

I bought a HP Envy 700-160eo desktop computer 5 or 6 months ago and for the last 2 months the CPU fan has been running really fast even at low temperature. It's like locked to about 2400RPM as soon as I boot up my PC. Even if I get 30 degrees celcius it runs at 2600RPM. I've tried resetting my CMOS and tried updating my BIOS, but the BIOS update that you are providing me on the HP Envy 700-160eo driver & update section isn't compatible with my PC. The update is for 700-0xx. I've been using the program called Argus Monitor for controlling my fan speed.

I've got the opposite problem, my AMD CPU is running around 55C and the fan hardly ever exceeds 1200 rpm most of the time its running around 950rpm. I think the 48C to 65C is running on the edge of to hot in my opinion, I like to stay around 35C-40C. Motherboard, video card and hard drive all stay in the 30C range.

CPU fan running at 3900 rpm tried everything so far.

I have an early 2008 imac running upgraded ram, Mountain Lion 10.8. I hve a CPU fan that is running at 3900 rpms. I have downloaded the SMC fan control, I have tried doing the option,command p,r. I have done all the shut down procedures. I tried ro restart in diagnostics mode but it wont restart in diagnostics mode (I tried using option D as well as just D on start up) I downloaded and tried using a shell app command with Automator that is suposed to force the fans tor run at a particular speed ie: 1200,1500,2400 etc. but it does not work. I do not have a start upd disc for Mountain Lion. Don't know what else to do.

I have tried running the hardware test I cannot get it to run starting up while holding D or starting up while holding option D. I do not have a OS X
install DVD 2.

It's clear that there's a problem with your Mac, so the best you can do is to make a backup of your files and take your Mac to an Apple Store or reseller to get it repaired.
If you want to know what's failing, run Apple Hardware Test > http://support.apple.com/kb/HT1509?viewlocale=en_US&locale=en_US
In your iMac, Apple Hardware Test is included in the Mac OS X Install DVD 2, so insert it and hold the D key while your computer is starting. Disconnect all peripherals except the keyboard and mouse, choose your language, mark the box to use the extended mode and start the test. At the end of the test you will probably find an error, so copy it here

ODD and CPU fans running at high RPMs

Hello!
My iMac's ODD and CPU fans are running at unusual high speeds. If I turn the computer off and on they usually run at a normal rate but start rotating at around 3700 RPM very quickly (about 1-2 minutes after the OS X has started). The CPU load is not unusually high. The HDD fan is not affected.
I have tried SMC and PRAM resets multiple times.

Thanks!

For some reason the high fan RPMs had to do with having two desktops under mission control.

PMG5 Dual 2.0 CPU Fans Running at (very) different speeds

I purchased a refurbished PowerMac G5 Dual 2.0 from Apple 8-10 months ago and I always thought the fans ran louder than I expected. Recently, I opened the case and noticed that the bottom front CPU fan was running much slower than the top CPU fan (with the clear shield in place). I checked this with software and here is what I found...
CPUA ~ 300 rpm on average
CPUB ~ 3150 rpm on average
CPUA Temp ~ Amb 46C
CPUB Temp ~ Amb 37C
Nothing changed when switching from Highest Performance to Automatic. Is there a sensor that needs fixing/cleaning or should I take it in for service?
Thank you for your help!

Yes take it in, this is a considerable difference.
There is only a few hundred (at most) RPM difference between my CPU A and B intake fans.
Either you got a dead processor or your fans need to be recalibrated or your firmware isn't right.
All three cases is a good reason to have Apple look at it.
It might be the software your using to read the fan speeds, download Hardware Monitor, it seems to be the most accurate and up to date.
I'm sure you have stressed the processors and checked in Activity monitor to see if both your CPU's are alive and kicking.

Need new CPU fan

Howdy - The CPU fan is making one heck of a noise. Can you recommend an aftermarket fan?
Stats are below.
Thanks
Joe

Just check,whatever you get, that at least its got a 4 pin PWM controlled fan. And as was mentioned, if you are not overclocking, a lower end HSF should be fine. The cooler Henry mentioned would be a very good choice.
Here is a host of coolers to choose from. http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&N=-1&isNodeId=1&Description=amd+cpu+cooler
