IPhoto 9.4.3 high fan speeds/ high cpu usage.

For about a month now, my iPhoto has been acting up. My iPhoto CPU usage idles at about 30% and as soon as I start using iPhoto, the CPU usage can go as high as 430%.. This causes the fans to spin at 6000RPM and eventually iPhoto will slow down and I'll have to force quit.
I have tried:
- repairing the iPhoto library
- creating a new library
- re-installing OSX Mountain Lion
- re-installing OSX Mountain Lion and then installing a fresh copy of iPhoto
- rebuilding the iPhoto library with iPhoto Library Manager
Nothing has fixed this issue. I have exhausted all of my options and I would greatly appreciate any help.
Cheers,
Joey

Did you remember to quit iPhoto before deleting the caches and to log off and on again? WIthout logoff or reboot cleaning the caches may have no effect.
iPhoto is keeping second, hidden cache in $TMPDIR. Try to clear that as well.
You can only open that cache from the Terminal.
Quit iPhoto.
Open a Terminal window and enter
open $TMPDIR
and hit "return".
In the window that opens remove the folder com.apple.iPhoto.
log off and on again, and retry.
Im thinking that this is a software bug.. but I just cant figure out why its happening on a fresh install of OSX / iPhoto. Seems bizzare.
I am using the same iPhoto version on a similar early 2011 MBP Mac without problems. Maybe the file type of your photos and/or videos makes a difference. What media kind are in your iPhoto/Aperture library? Videos? Raw? Jpeg?

Too high fan speeds? 15" late 2011 MPB

Hi!
I bought my new 15" MacBook Pro in the end of november, and it is therefore the late 2011 version.
I have huge problems with the fans, though. Since day one, I have always thought that the computer was kind of loud, in comparision to my 2009 13" MacBook Pro, but just thought that since this new computer is more powerful, with the i7 CPU and everything, it was normal.
Now, a little more than two months later, I have had enough. I have tried using Google to find an answer to this extremely annoying problem, but everyone is saying the same thing. Reset the SMC, reinstall OS X, install Fan Control apps, etc. I have tried everything, and nothing works as it should do.
When in idle, with nothing but Finder on, the average temps and fan speeds are:
CPU: 52°C
CPU Heatsink: 47°C
GPU: 45°C
Left fan: 3700 RPM
Right fan: 2600 RPM.
I have tried using Fan Control apps (smcFanControl and Fan Control), resetting SMC, etc.
If I look in the activity monitor, everything looks normal. Nothing that spikes out of the ordinary. Every time, it is the activity monitor app that has the highest percentage or CPU percentage.
When having Safari and my mail client Sparrow on, and just casually browsing on the internet, the average temps and fan speeds are:
CPU: 64°C
CPU Heatsink: 60°C
GPU: 49°C
Left fan: 4300 RPM
Right fan: 3200 RPM
I would understand if I had these temps, fan speeds and noises if I were playing a graphic demanding game, or using Photoshop and Xcode.
Computer spec:
Intel Core i7 @ 2,4 Ghz
8 GB RAM-memory
AMD Radeon HD 6770M 1GB
750 GB Hard Drive
Late 2011
I am writing here and explaining my problem since I am not sure if I should go to an Apple Store and let them deal with it. Maybe there's nothing wrong. Maybe these temps and fan speeds are normal, and then I just have to adjust. Otherwise, I know that there is something wrong, and I will let Apple fix it.
Thank you in advance for any help!
I appreciate it.
Regards, Anton

Agree with Ogelthorpe. You have some type of hardware problem.
More then likely the heatsink that removes the heat from both the CPU and GPU is malfunctioning and has been from the first day.
I'm running a 15" 2.2 i7 with 8GB RAM 120GB SSD 500GB 5400RPM HDD and right now my CPU is 41c GPU is 34c and I have Chrome, Lightroom, DNG converter, Thunderbird, and Word open.
Yes take it in and get it fixed.
I would of taken it back the day after I bought it, compared it to the units siting on the floor of the store I bought it and then asked for a new one.

Prstat displays PROCESS/NLWP with /0 , but high USR and SYS cpu usage

I'm running prstat on Sol 10u4 sparc and see from time to time one of more processes with high user and kernel cpu usage, The process name is just displayed as " /0". What is this ?
see sample snapshot below:
PID USERNAME USR SYS TRP TFL DFL LCK SLP LAT VCX ICX SCL SIG PROCESS/NLWP

18734 root 3.7 8.9 1.0 0.0 0.0 0.0 86 0.5 52 52 3K 0 grep/1

The slash number format is used to show the number of threads (light weight processes or LWP in Solaris parlance) in a given process (see the header says "PROCESS/NLWP"). I'd guess this is a race condition where prstat finds a process exists and has consumed some CPU, but when it goes to query the data on the process it's already exited so there's no process name and zero threads associated with it. For this to be true and to see this except more than every once in a blue-moon you'd have to have a system that was having processes forked at an amazing rate.
I'd also say this is a bug, but one that you might have a hard time getting an traction on.

Mac mini slow and high fan speeds

Hello! I have a 2011 mid range mac mini and love the machine, however I have noticed a few things. First off, it seems to be a bit on the slow side when multitasking. I have the standard 4 gigs of ram installed, but running programs like MS Word and Safari at the same time, the machine seems to struggle a bit. Also I have noticed when doing a lot of file transfers via USB, the fan will kick up to high gear for a few minutes and then drop down. Is there something wrong or is this normal? I'm doing a time machine backup of 120Gigs, have safari open and activity monitor open.
Activity monitor states 1.16Gigs free, 792MB wired, 961.4MB active, 1.12GB inactive, 2.84GB used. VM size is 150GB, page ins are 962, outs are 380kb, swap used is 10.5MB. Right now the fan seems to have slowed to a mid range mode of some sort and is not in high gear. Thanks!

How many apps you instaled? how many pictures videos and time you get usigm it? let them a litlle sleep, and your mac nmini will ne wel.
As far as the fan is concerned, it will rev up and down
based primarily on CPU load. If something is using
up a lot of processor, it gets hot and therefor the fan
speeds up to cool it down, or atleast maintain a safe temp.
When the fan revs up, open Activity Monitor and see how
much processor resources are being used and look at
the list to see if any one process is using up CPU. This
can also give an idea of what may be slowing things down
as well.
And yes, when doing a lot of file transfers, things may
possibly rev up a bit if it is continuous for a period of time.

Extremely High Fan Speed

A few times in the past month I've left my computer on and left the room, only to return to a computer that won't "wake" from hibernation and has an unbelievably high cooling fan speed. It's not like the normal hum of a fan, it's almost like it's a room-sized air conditioner is running. The fan is moving (or sounds like it's moving) massive amounts of air. The Power Mac won't stop unless I press and hold the power button until it shuts down. I've read many posts about fan noise, but nothing like what I've experienced. Is anyone familiar with this problem?
PowerMac G5 2.3Ghz Mac OS X (10.4.6) 2.5GB RAM, 250 GB HD

Hello, thread viewers.
I also have a G5 (dual 2.7Ghz) which is stock, from Apple, with 2GB RAM and the same intermittent problem of "freezing" while sleeping. The fans are running at full speed when I find the machine like this, though the case isn't particularly hot (making me think the temperature feedback has failed more than that the processors are cooking).
Extensive examination of the system log has revealed no obvious common message prior to this situation. As it happens only once or twice per month and I cannot predictably reproduce it, I cannot guess as to what is causing the problem. If I recall, it occurred with OS 10.3 as well as each release of 10.4.x.
I have run every test I can think of without an obvious problem. I have reset the PRAM and NVRAM. I have repaired permissions and verified disc status multiple times without change (and without detecting any unusual errors). I am a veteran Mac user and I cannot think of further diagnostic routines to get to the bottom of this vexing problem.
I don't have odd peripherals attached, and the ones I do have are usually off (FireWire drives, for example). I have tried several times to ssh and rlogin from other machines to the system when it's in this state without avail. The computer simply fails to respond to these commands, as well as to ping requests. The core OS is not responsive to outside prodding.
Anyhow, I can say that, at least in my case, the solution to this problem is definitively NOT the usual suspects, as outlined above. I am reluctant to give the machine back to Apple at this point because (1) without an obvious trigger or cause, the repair is likely not to fix the problem, and (2) I don't want to spend the time cloning, cleaning, then reinstalling my system for a shot-in-the-dark hope that they'll replace some faulty component that can fool the diagnostic software into thinking it's OK.
Please post any progress made so we can focus our efforts! Best of luck! I'll be following this topic anxiously!

High fan speed (but not 100%) following hard drive upgrade

Hi,
I recently upgraded the hard drive on my 2007 Mac Mini to a 320Gb Western Digital Scorpio Black. Since then, the computer's fan has been very annoying. The fan is not running at 100% all the time, but it ramps up very quickly when the computer is under the lightest of loads. Simply scrolling a webpage will send the fan speed up to around 4500 - 5000 rpm.
My first instinct was that the 7200 rpm drive was creating too much heat, but the temperatures are all fine with the hard drive around 30 - 35 degrees C and the CPU around 35 - 40 degrees C, at a fan speed of 1500 rpm. The temperatures drop down to the 20s when the fan ramps up.
The problem is as described in this article: http://support.apple.com/kb/HT3964
"The computer's fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated."
I've followed the reset SMC procedure several times and yet the problem persists. Can anyone help me to solve this problem? Given the low hard drive temperatures and the fact that the fan is spinning up without disk activity, I'm hoping the drive isn't to blame. I'm getting fairly experienced at working inside the mini, having done three memory upgrades and two hard drive changes, but I would still like to avoid opening it and changing the disk again.
Thanks,
David.

Same thing happened to me. Upgraded HD and RAM, fan spins up at a mere scroll of a web page.
I checked the usual suspects -- vents, foam "T", physical placement, cables back in place.
Also, I went back to the original equipment and found it still "wound up" quickly.
Another data point -- when the fan is accelerating and when at speed, the air coming out of the vents is not very warm. Windows laptops I use discharge very warm air when the fans spin up. Could the calibration of the CPU temp guage be off?

Imac high fan speed and goes to sleep 10sec after wake-up

Hi,
Since today my imac's fan speed is high (optical fan and cpu fan speed at: 4000rpm)
Done a hardware test wich gives me 4SNS/1/40000001:IDSR-0.000 indicating something with logic board. According to istat all my temperatures are below 35°C (95°F). istat has readings for the cpu and optical drive temp (both around 26°C)
On top of that if I put my imac to sleep after wakeup (give or take) 10sec later it would go to sleep again. tried the smc reset procedure. no success
Any other tricks to try or just go for an exchange? (imac was bought on 2feb2010)

I've had this problem since replacing the MLB in my iMac a few weeks ago. Initially brought in for repair when the CPU fan came on at 4k rpm and stayed on even after SMC reset and nvram reset. First replacement MLB was a dud, second corrected the fan problems. Now I'm having the sleep issue, I can't tie it to any particular process. Initially I thought it was graphics related as it would go to sleep during graphics intensive work, but yesterday it was doing it when just copying data to an external drive. The temperatures of the CPU and the GPU diode are within spec. I now use a fan controller to keep the CPU fan at 2100rpm and the HD fan at 2100rpm and I don't have the problem. From what I can tell now is that a sensor is incorrectly reporting temperatures intermittently. It may not be the MLB or the graphics card specifically, but the cable connecting the sensor to the board. I ran AHT after the last time it did this and it failed a sensor, but after running ASD on the machine it passed all the hardware. I'm bringing it back into my shop later this month and if i can remember i'll post here with the resolution, not much I can do at home beyond software diagnostics.

T420s High Fan Speed on Idle

Even with TPFancontrol installed, when sitting at idle, my 420s fan runs high. I am on Windows 8.1 with no maintenence in the background.
Any idea what causes the fan and CPU to increase sitting idle on Windows 8.1.
btw; this is a fresh install with most of the Lenovo stuff removed. The Bios is updated. Hard Drive is Samsung EVO SSD.
As soon as I touch the computer, the fan stops.... CPU goes down to 63 C...
Thanks,
Solved!
Go to Solution.

The issue is with Windows 8.1 maintenance on idle feature. I deleted the scheduled task and resolved my fan issue. I even removed TPFan as I no longer needed it. (Didn't work for this anyway)
I prefer to perform my own maintenance so unless removing this scheduled task gives me performance issues, I prefer the silence.
Thanks for the help...

Extremely high fan speeds while using Skype

I have a MAc book pro intel based, the fan goes on whirling at the hihgest possible speed even when there is about 30% of cpu usage i tried the SMC and the PRAM reset but it hasn't helped me at all.
Does any one ave any idea how to fix this problem?
Thanks

Hi wjosten
As you requested. pls let me know if u need anyting else,
thanks

Kernel_task high cpu usage, high fan speed, and low cpu tempterature

Hi,
I've noticed that a lot of people have been having trouble with the kernel_task process, but I couldn't quite find a situation similar to mine (most seem temperature related).
Here is the situation (15' MBP, mid-2010):
- on boot (while the apple logo is shown), the fans speed suddenly jumps, and stays there, even if the computer has been off for a while.
- boot takes a little over a minute, which is considerably slower than what I was used to before today
- when finally started-up, the activity monitors shows kernel_task using between 160-180% of the CPU!
- temperatures are shown to be around 30C, except for the mem controller at 40C (still very low temp), but the fan speed is arround 6000rpm for both fans.
- this happened out of nowhere, as I woke the mpb from sleep this morning.
Since then I've tried:
- multiple reboots
- install all updates
- uninstall flash player (some people where having trouble with that)
- empty the system cache with Onyx (reported as a cause of slow boot)
- reset PRAM
- reset SMC
- put some ice packs under the mpb to cool things even further!
And so far, nothing has worked! I've had this laptop for 1 year, and nothing had ever failed. I upgraded to lion a few weeks ago, and everything had been working fine since the upgrade. This really happened out of nowhere, and none of the many forums I have read could offer a solution, and cals to apple support do not seem to yield better results (though I scheduled a call with them at 9am this morning, we'll see).
Has anyone had a similar set of problems?
I appreciate any help or advice you may have!
Thanks!
-Sebastien

I have the same issue (2.66 2010 MBP Hi-Res Anti Glare.)
I took it to Apple Store Covent Garden, JUST within warranty.
18 days later my machine has a new Main Logic borad, heat sensors, top case, palm rest. etc.
I turned it on.
The fans kicked in. All processors at 50%, big ole kernal task.
I took it back, geniuses rest SMC and tested it under load and it was fine.
weirdly it failed diagnostics at first but then seemed fine
I came home. Fans kicked in...
I took it back. Diagnostics failed heat sensors again
Replaced logic board and heats sensors again, but more carefully this time just in case, tested again.
I took it home. FANS FANS FANS.
Last time I was in the store I was told my machine was fine and had been thoroughly tested.
In mac store, no fans.
I erased hard drive and clean installed Lion
FANS
I replaced hard drive with OCZ SSD, clean LION.
Fans
Software update
SMC
PRAM
permissions
Onyx complete clean/maintenace
FANS/CPU
switched back to Snow Leopard SSD
PRAM SMC ONYX etc.
FANS/CPU
replaced RAM, memtest-ed. fine, FANS
gonna try again but up to nearly 2 months of all my spare time trying to shut this thing up so I can sell it.

NX6800-TD256E PCI Express - NOISE, NO ULTRA COPPER, very high FAN SPEED

Well I also have bought a NX6800-TD256E PCI Express.
The card was advertised at MSI.COM.TW with ULTRA COPPER and adjustable Fan Speed.
One week ago on the website of MSI the card had Ultra Copper. Now, not any more. :hypecrite:
When I bought this card 4 weeks ago:
1. the website information about this card was with UltraCopper
2. the website of the dealer was with UltraCopper
3. the packing is with ultra hopper
4. now I can not adjust the fan speed
http://www.msi.com.tw/program/products/vga/vga/pro_vga_detail.php?UID=639
Even the packing shows ULTRA COPPER.
Nothing true, and this for EURO 365.00. Shortly in my mind this is unfair competition. There is a law in Europe: "law against unfair competition". Maybe not in the US and TW.
Who else does have the same trouble ?
Is there a solution with MSI ?

This is a user to user forum only, no MSI techs or representatives are present.
If you have the means to follow up legally, then do so, but this is not a place to start a rant or a petition. Please contact your reseller for a refund or exchange.

High fan speeds and high GPU temperature during idle

Hi,
I'm hearing slight similar problems around this subject but this one seems to be obscure.
My iMac 20inch (Early 2008 - 8,1) has just passed by the 3 year mark now and only yesterday just suddenly started haven't this weird gain in fan speeds mainly on the CPU.
Checking the temperature in iStat shows that its coming mainly from the GPU (GPU - 79c / GPU diode - 91c / GPU heatsink - 83c) and that's from looking as I type this.
I've done the SMC reset a few times and the PRAM reset too, but that's only managed to make things worse...occasionally on startup after the resets the screen will blank out and ask me to reset.
Below are screenshots from istats of the state of my iMac during idle:
Hope someone can help and this be of some help to others in the same situation.

I think a SMC reset will handle this for you. If not then also do a PRAM reset.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Gtx 680 high temps and high fan speed

I have my card since a few months and I always thought it was normal, until 2 days ago when a friend came over with his card an we did some tests to compare.
When I play most games my card is at about 70-80c and 70-80% fan speed.
We did a simple burn in test with furmark and after 2 minutes my card was at 84C and 78% fan speed while his was in the 60C range while staying quiet.
Of course his card was fresh out of the box and his case is bigger, so more spacing, but mine has more cooling, especially for the gpu. Could it be the thermal paste? I see people having way better results with this card than what I am getting...

Quote from: dude on 25-March-13, 01:01:37
Since it is a pretty new card I think it's airflow in your case. I read somewhere here someone gave instructions for replacing thermal paste.
My card is about 6 months old. It's just that I always thought it was normal, even if I was disappointed with how loud the card was, since I bought this one espcially for the good cooling and low noise that I've read in so many reviews and tests before buying.
However, my friend's card is brand new. He came at my place so I could build his computer. My case is a full atx tower, while his case is etax. But, my cooling was done and redone many times, espcially since my card was loud and hot, I decided to change my cooling (which did not even change 1C). I clean my case really often and my fans are well arranged to get the best airflow possible, while my friend's case has less fans and are not optimzed (intake-outake...) to have the best airflow.
Maybe the spacing really is for something, but 84C in 2 minutes of furmark with almost 80% fan speed is a lot.

CPU load LOW - Fan speed HIGH - WHY ?

Hi
I'm watching youtube videos on my mac - under Windows XP (bootcamp) - I'm monitoring my CPU usage while watching the videos because my fan is spinning at full speed - yet the CPU is not working hard - about 5 to 10%. Does anyone know why the computer is getting hot and fans spinning faster if CPU load is still very low? Is it possible that I only see one of the cores in the windows monitoring system? I press control alt delete to access the info.
Any suggestions would be helpfull
Thanks

Hi tcdm1972,
A lot of postsfrom fellow users report their fan kicking out loud mostly when watching or using application that related with video or streaming video.
I'm not an apple tech, so I guess that fan also try to cool down the GPU chip sets since it is dinamically adjusted in and out of allocated memory and rendering or streaming video to the screen and become hot as well. (I could be wrong).
And most of the time the fan kicking when macbook plugged with mag safe (processor runs optimal clock speed).
Hope other user have different opinion.
Good Luck.

Tweak the balance between fan speed and CPU temperature / Dell M6400?

Hi all,
I have a Dell Precision M6400 17" laptop. It runs really well on Arch, but is a bit noisy. It has always been noisy, btw, but I recently noticed that the CPU fan was blowing a lot of air even though the CPU temperature is lower than 70°C. I also have a macbook air, and its CPU runs at 70°C all the time, which seems to be normal. I would like my m6400 to behave similarly, and I'm sure someone here know how to change that

When I start the laptop, its CPU fan stays at its minimal speed only for 1 or 2 minutes, then increases its rotation speed to a second level. It reaches it maximal speed only under heavy load, when the CPU reaches >80-95°C. I would rather let the CPU run a bit hotter before the fan starts to blow: let's say the fan could enter its intermediary speed between 70°C and 85°C instead of 55-80°C, and blow at is its maximum speed beyond that.
I checked the Fan Speed Control wiki page, but lm-sensors is not able to show me the status of the fans. Any idea ?
Aurel.
PS: the temperature of the GPU is not reported by sensors, and nvidia-settings reports around 60°C. Its dedicated fan is very quiet.

Hi all,
I have a Dell Precision M6400 17" laptop. It runs really well on Arch, but is a bit noisy. It has always been noisy, btw, but I recently noticed that the CPU fan was blowing a lot of air even though the CPU temperature is lower than 70°C. I also have a macbook air, and its CPU runs at 70°C all the time, which seems to be normal. I would like my m6400 to behave similarly, and I'm sure someone here know how to change that
Hi aurelieng,
I'm in the same situation from at least 1 month ( INTEL CORE 2 EXTREME X9100, 3.06GHz with 8GB ram, one solid state disk 128 GB, and one sata disk 500GB)
My dell M6400 has dual boot: ubuntu and windows7. The fan works a lot and continuosly in both environment and this is the reason because I have doubt that the origin of the problem is in hardware problem?

IPhoto 9.4.3 high fan speeds/ high cpu usage.
