PMSET Uses 50% CPU Keeping Fan Running

I am having the same problem as described in this (archived) thread (no solution):
http://discussions.info.apple.com/thread.jspa?messageID=11226077&#11226077
The only thing that appears to 'fix' pmset (at least for a while) is a reboot. This is not a permanent fix since, as time goes by, pmset eventually starts kicking up a fuss and using 50% cpu for regular periods of time--enough to keep the fan running pretty good.
Also, it appears that if the machine goes to sleep/hibernates the pmset issue raises its ugly head sooner.
If I'm running on battery, this seriously impacts battery life; which is rather ironic (not to mention frustrating) since pmset is supposed to be properly performing "power management".
I did try resetting the SMC (http://support.apple.com/kb/HT3964) at one point, but alas there was no lasting remedy.

For some reason, it occurred to me that I should try disabling bluetooth, which I did shortly after posting this issue. I have not seen abnormal pmset behaviour since then.
Since I have a bluetooth keyboard and mouse this would not be an ideal setup for me to run with at all times.
Any ideas out there folks?

Mbp pro retina 13" after installing mavericks keeps fans running in sleep mode.

Hi. my Mbp pro 13" retina keeps fans running in sleep mode, tried to reset smc but not helping. So maybe someone have some solutions?

Dock consumes 100% of CPU and fan runs. What to do?

I have a 2010 MBP with SSD and VMWare (not Parallels). Every so often, the dock cranks up to consume 100% of the CPU, and the fan runs. The problem goes away when I reboot. I've tried quiting various applications, but it doesn't seem to make a difference (i.e. I cannot identify a rogue app that's causing this). There are a lot of discussion threads on this problem with OS 10.6.8 and Parallels, but I'm running Lion 10.7.1 and VMWare (which I've shut down).
Any others have this issue? Ideas for solution?

Small update: Despite my intelligence, good looks and vast experience I use Google sometimes. To my surprise this file turns out to be a Windows one. Here is someone who is much happier, and since it is some way in my line of thinking I'll quote it, but you might take my previous advice as well:

Cpu and fans running at 100%

I've been working on this 20" iMac G5 for a couple weeks now and I'm stumped.
I've reset the smu, the nvram, wiped and put on a fresh install of 10.5, updated to 10.5.8 and still the computer is LOUD.
The fans run at a constant 100%, so I check the processor temp and it was 85c the instant the screen came on. So I proceeded to check the ventilation, took it all apart and all the air ways are clear, I checked, cleaned, and applied brand new thermal paste, put it all back together and still the instant the screen comes on the fans go to 100% and temp jumps to 85c
Then a student said "is it working hard?" Just to humor him I launched the activity monitor and to my surprise it was. The processor was running at 100% and the process that was doing it all is "top" running from the user 'root'.
I proceeded to type kill 321 (the pid) and the processor dropped to 10% and after about half an hour the temp was a normal 60c and the fans went quiet, but the instant I log out or reboot that 'top' process kicks back on and the machine starts over heating.
I've tried 10.4 and 10.5, wiped the HD about 5times and 'top' keeps running the processor off the deep end with every install.
I've tried permission repairs and hardware checks, even ran the full techtools deluxe scan.
I've tried finding others with this problem but it is understandably difficult to search for problems with 'top'.
It is no longer under warranty and no one is going to miss it if I just throw it out, but I don't want to give up on a 2.1Ghz machine for student use if that can be avoided.
I'm willing to try any ideas to get that process fixed, the only idea I have left is to replace the cmos battery, and prey to the computer gods, but I doubt that will do anything.

Hey there - same problm here w/ white flatscreen G5 (PPC).
Did you have any luck in solving your problem?

Mavericks keeps fan running all the time

I upgraded to Mavericks and every thing seems to work ok (except maps) but my concern is that now i hear the fan running slowly all the time. Even on battery power the fan runs. I don't remember this in mt lion, and wonder if this is normal with os x 9 or something i need to worry about. I would guess it would use more battery when not connected to the power supply. Any ideas as to this problem?

Some users have reported Dropbox is using an inordinate amount of power, but your system indicates nothing extreme. You might try uninstalling it to determine the result. Your Dropbox account won't be affected, and you can always reinstall it.
If you haven't yet updated Dropbox do so, because version 2.4 is required for Mavericks and a maintenance update was released only yesterday.
Also, there have been reports that an SMC reset has been beneficial. It is generally justified for any power - related anomalies including abnormal fan activity.
Follow all the steps, even if they seem unimportant. The power adapter indicator light should cycle off / on once when you reset the SMC.
Before Resetting the SMC
Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
Resetting the SMC on portables with a battery you should not remove on your own
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.

SyncServer constantly using high CPU, causing fans to run

Has anybody found a solution for when the SyncServer process runs wild? I'm running OS X 10.7.1. In the last day or so I've had a problem where I find my laptop's fans are constantly running. Opening Activity Monitor shows the SyncServer process eating a consistent 20-30% of my CPU. I've left it going all day and it never stops.
From what I've been able to determine so far, the SyncServer process doesn't cause any problems until I launch iTunes and sync my iPhone. After that it keeps running. I upgraded to iTunes 10.4.1 yesterday, but I _think_ this problem started just beforehand when I was still running 10.4.
If anyone has any insight I'd appreciate it.

I resolved a similar situation. I am running OS 10.6.8 and noticed my fan was on constantly. ActivityMonitor showed the syncserver process using about 15-30% of CPU cycles, with iCal showing up suspiciously high on the CPU list. I downloaded syncrospector v4.0 from http://goo.gl/logoG (I got that lead from http://help.jools.me/kb/21) and running that app I could see that iCal was syncing about once per second! A bit more searching took me to http://support.apple.com/kb/TS1627, and there I found the answer.
"If you see the Sync menu in the menu bar, skip to step 4: "
I hadn't noticed the little icon in the menu bar, but there it was with an exclamation mark inside it. Clicking on that I saw a message that there were "conflicts" (about 10, it turned out). I resolved those and the syncserver problem went away.
Now, there is probably an underlying problem, still. Just because there are conflicts between iCal and my iPhone, iCal should not be trying to sync more than once per second. For now, though, I am content. I'm not going to try to figure out what was really going on.
By the way, this all started when my daughter plugged her iPhone (an old one of mine) into my laptop. Evidently the old calendar entries on that phone for some reason conflicted with old entries on iCal.

Ditto Using A Lot Of CPU? Fans Run Often

It seems to be the culprit in causing the fans to run fast since installing SL. I stop the process from the Activity Monitor but it starts back. AM shows ditto at 90% when it's running. The fans come on, I stop ditto and they slow down, later the fans come on again, I check and ditto is running again and at 90%...............

Actually resolved this. Related to unzip issue.
Attempting to unzip some files locks up the Archive Utility. Force Quitting the Archive Utility leaves ditto open and using a lot of CPU.
Therefore, I'm using The Unarchiver (as kindly suggested by someone on my unzip problem post) at least until Apple updates the Archive Utility.

Very high CPU and fans running fast in idle state on 2008 non-unibody Macbo

Hi everyone,
I recently purchased a 2008 MacBook with 2.4 GHz, 2GB RAM, and 160 GB hard drive off of craigslist. Now when I turn it on and leave it idle or even run any activity, the CPU skyrockets to around 66% and the fans are running very hot and fast. I checked activity monitor and nothing is running that indicates this high CPU. This MacBook does have AppleCare on it until August 2011 and I will probably bring it in to have it checked out but would like to know what you think.
Thanks!

ok the abttery charges to 100% now so its alright but sometimes the charger turns to a dim green for some reason and doesnt stay bright only until I unplug and plug it back in again.
in regards to the random CPU spike, here is a screenshot of activity monitor, hopefully you guys can tell me what mds is..

Fans run continuously - they didn't before, is that ok?

the fans of my mac pro run contiuously, never stop, even there is no application running. When i got my mac they used to turn on and after a while off. I configured the mac as it was originally but it didn't change. The AHT says everyting is fine.
I wished the fans would turn off sometimes.
I didn't find an answer in this forum yet.

I had a similar experience. Adding a PCIe FW800 controller was probably the reason for mine.
The fans should be running to insure cooling and to protect RAM and components.
I now use smcFanControl to keep fans above their normal 500-600 rpm. You can monitor fans, drives, memory, etc. temperatures using Hardware Monitor.
The only way for them to turn off is if the room is air conditioned. Usually it is hard drives that people hear that are annoying because the case is both very open, and also quiet.
The memory runs very hot, which is why they have large heat-sinks, and advised to wait 10-15 minutes to allow them to gradually cool down before opening the side door - the sudden change of temperature is a shock and stressful.

Fan Runs constantly on MBP

Last week, Apple Store replaced my brand new MBP with this new MBP because of continuing problems with the first one. Now after a few days, the fans are running constantly as soon as I turn it on. Probably a sensor issue, although I don't want to take it back and have them start opening it up. I use iStat Widget. Fans run about 2000 rpm from the moment I start the computer up. Anybody else have this problem? Won't this drain the battery? Any solutions? Hardware or Software problem? I already reset the System Management Controller.
I suppose I will have to go back to the Apple Store, I was back and forth with the 1st MBP and now this problem. If they open the laptop up, it always seems to get worse and worse.

The system default is "fans on" at 2000 RPM. At that speed I cannot hear mine running unless I put my ear almost on the keyboard. Even smcFanControl (a third-party fan speed controller) will not let you set the speed below this point, leading me to assume that this airflow airflow volume is important. When the temps begin to rise, the fans speed up to move more air.
The highest temps I've seen on my Santa Rosa MBP are 160F/71C, and the fans are running at just under 5000 rpm (Max is 6000). As it cools down I can hear the fans start to slow around 140F/60C.
What I see in your description is normal behavior unless one or both fans are making screeching or loud whining noise.

Fan running at high when cpu not being used, Macbook not responding - Help!

Please help!
Quite often now when I leave my macbook for an a few hours (the screen goes to sleep but not the computer), I come back to the fan running at full speed and then when I touch the trackpad, I can move the mouse around, but nothing responds (i.e. when I move the mouse over the dock, the dock doesn't pop up...and I can't click anything on the desktop). So I have to hold down the power button to shut it off and then restart the computer. Then it works fine, but if I leave it for a while and come back, half the time I come back I encounter this problem again.
Any help?

Check your activity monitor. Sounds like you have a program running in the back ground your not aware of.
You might also try to reset the SMC and/or PRAM.

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.

Macbook Pro fan running constantly and CPU running slow

So, I have a Macbook Pro 2010 2.3 i7 that has started running really slow and the fan is running constantly.
In activity monitor it shows a kernel_task running constantly at around or above 200%.
I have tried all the regular tasks. PRam reset, SMC reset and nothing seems to fix it.
I have also tried a system reinstall to no avail.
Maybe I'm on the wrong track, but from what I have read, the kernel_task might be trying to slow my CPU down because it thinks it is being overworked?
Maybe the fans are also being activated because it thinks the computer is too hot?
Anyway, if anyone has any idea as to what I can do to figure out what is going on, let me know. Thanks

I'm running mainstage on my new macbook pro, and the CPU keeps maxing out. WHY????

SO, new macbook pro, and logic runs like a dream, 10 instruments, 20 tracks, all is well...
However, mainstage is killing me. I can see the amazing potential, but the CPU keeps spiking, literally when I try to loopback 1 instrument. It is ridiculous. I'm verging on submitting to Ableton, help me please!
Robin

Did you check the I/O buffer size in Preferences/Audio? It can well be, that small buffers like 32 frames may screw the show. Which instruments are you using? MS in single threaded, so everything is processed on a single core.
Best,

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.
