Software to Monitor CPU and Fans

I have an MSI 785G-E53 with a Phenom II x2 (with all 4 cores unlocked).
What program can I use to monitor the CPU core temps, fans, maybe even the hard drives too?
I tried both speedfan and coretemp and neither looked like they pulled the CPU core temps, but maybe I was doing something wrong.
Should those work? Is there a better utility to use?

Is that because I have the cores enabled? Are you saying that if I didn't do the core unlock, those apps would work? There's something about unlocking the cores that's "breaking" those apps?
Yep, exactly that. I had the same thing when I unlocked my Athlon II X3 440. I don't know what it is exactly but unlocking the cores stops the sensor from picking up the core temps.

The kernel is using excessive processor cycles. Below are some possible causes for the condition.
Throttling
When it gets high temperature readings from the hardware, or low voltage readings from the battery of a MacBook, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to:
☞ a buildup of dust on the logic board
☞ high ambient temperature
☞ a worn-out or faulty battery in a portable
☞ the malfunction of a cooling fan, a temperature sensor, a voltage sensor, or some other internal component
Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.
If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on AC power, charging is causing the machine to heat up. That behavior may be normal for some models. CPU usage should drop when charging is complete.
Apple Diagnostics or the Apple Hardware Test, though not very reliable, is sometimes able to detect a fault. For more thorough hardware testing, make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
If nothing is wrong with the hardware, then whatever you can do to improve cooling may help.
Installed software
User-installed software that includes a device driver or other kernel code may thrash the kernel. That category includes virtualization software, such as Parallels and VMware, as well as most commercial "anti-virus" products. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or starting in safe mode. Note, however, that disabling a system modification without removing it or testing in safe mode may not be as easy as you think.
Corrupt NVRAM or SMC data
Sometimes the problem is cleared up by resetting the NVRAM or the SMC.
External display
Connecting an external LCD display to some MacBook Pro models while the lid is open may cause this issue. If applicable, test by closing the lid or disconnecting the display. You might get better results with a newer LED display.

Is there a VI to monitor CPU and memory usage on wINDOWS 2000 system ?

I want to monitor CPU usage and available memory for Windows 2000 computer. Is there a VI that can call the task mngr. via a DLL to provide this information in real time ?

There was a nice example using .NET technology, but it seems the link has changed and I cannot find it anymore. See this older thread for some clues.
Does anyone know what happened to the target of the original link in my old post?

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:

Print Manager App consumes over 99% of CPU and fans are constantly on.

Hi!
In Activity Monitor there is a Print Manager App taking over 99% of CPU resources and as a result, fans are on at full speed constantly, even if NOTHING is open. The user of this App is "_lp".
I understand that "root" and "myname" should be the only users.
The machine is a laptop that I use by myself (or so I though).
Are the above signs that somebody/something got inside my machine? I have also discovered MacFUSE in my System Preferences and I know for sure that I did not installed that one.
Any ideas or suggestions?
Thanks.

Force-Quit it. If it comes back on, post back and we'll see if we can figure out why.
I understand that "root" and "myname" should be the only users.
Those are the most common, but OSX has any number of internal users for various processes.

Doubful, but anything's possible. A Google search says it's a developer tool. Could be associated with some other 3rd-party app you've installed.
Is your firewall on? With the most restrictive settings?
Has your Mac been left unattended?
Do you need a password to sign on?

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..

Monitor CPU and send output to file

Hello
I want to monitor my CPU usage and my idea was this:
1. Use Top (/usr/bin/top –n 1|head –n 3| tail –n 1|awk ’{print $2}’)
2. Send output to file
3. crontab it
My problem is now that my top command (see above) works fine in terminal, it will give me a short and clean answer; 10.5%
But when sending this to a file the output looks more like: 10.5%^^8fewfwe[]€]]@£]@£[f9@£[]^^E^Efewfwef23 (Yes i just hit my keyboard but its alot of randoms characters)
How can i fix this?
Do you have any easier solution to monitor my CPU usage, i want it to be quite often, send cpu usage to file for at least every minute, then i can import this to excel and make nice diagram.
I dont want to install any extra program so ill have to work with whats there already. Im using RHEL 4.
Thanks in advance, Johan

A better way to do it is using "sar"
man sarIt's already builtin and there are plenty of docs on the net.

Closed Screen, External Monitor, Heat, and Fans

We have our MBP connected to an external Dell Ultra 22" dvi monitor (awesome!). We use apple BT keyboard and mighty mouse (again awesome!). Now, my concerns:
1. Screen damage from keyboard - I've read (to my disbelief) that mac laptop/portable machines can't be closed without some type of material laid on the keyboard to protect the screen. Is this true? If yes, does this cause a heating problem?
2. We use the MBP for email, web surfing, calendar, etc. Nothing very heavy at all. The fan comes on after 20-30 minutes of working and the machine is very hot (iStat 140F for processor and graphics processor).
Since moving over to mac at the release of the intel processors, I've bought 4 (17" imac, 20" imac, 24" imac, and now a 15" MPB). I do love the look and the OS but some of the issues are kinda silly. I can't believe we tolerate it so well.
Anyway, thanks for looking and any suggestions are greatly appreciated.
Leo

1. Screen damage from keyboard - I've read (to my disbelief) that mac laptop/portable machines can't be closed without some type of material laid on the keyboard to protect the screen. Is this true? If yes, does this cause a heating problem?
While many of us use some fabric that sits between the keyboard and the screen, such as ScreenSavrz its not needed. There is some clearance between the keys and the screen. I like it there just to be sure As for creating heating problems I don't keep the fabric on the keys while its own.
2. We use the MBP for email, web surfing, calendar, etc. Nothing very heavy at all. The fan comes on after 20-30 minutes of working and the machine is very hot (iStat 140F for processor and graphics processor).
My MBP runs between 50 and 60c which is right in the ball park of your temps. Ambient temperatures also effect how quickly the MBP will warm up. That is, if its 32c (90f) then the mbp is going to get hotter quicker. I recommend a little app called SmcFanControl It gives you the ability to set the fan speed and thus provide better heat management on your MBP.
Since moving over to mac at the release of the intel processors, I've bought 4 (17" imac, 20" imac, 24" imac, and now a 15" MPB). I do love the look and the OS but some of the issues are kinda silly. I can't believe we tolerate it so well.
Well all computers and operating systems have their own idiosyncacies. Overall I think Macs and OSX are so much superior to windows and Dells that I don't mind some of the stuff we need to put up with

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).

IMac (21.5-inch, Mid 2010) - CPU and Optical drive fans rev up to 4000 rpm

Hello,
I just want to share my experience with my rather new Imac
I bought this Imac last April and I had the fans roaring after 2 weeks of light usage. I followed instructions like resetting the SMC, unplugging the imac and restarted.
However, I started installing other software like Paragon NTFS, VLC, Firefox and also Istat nano. This happened on a more regular basis and istat nano was showing up fairly normal temperatures - an average of 50° C and I had the CPU fan at 3800 and the Optical drive fan at 4200 rpms. According to apple support, at this temperature fans should be running at factory level or a bit more. Even when I stop all activity, the fans keep up and does not stop even after a couple of hours of inactivity on the imac. Apple support recommended that I reinstall macos on a new partition and run tests and during the tests, the only software I installed was istat nano and still got the fans going with the same result - required a shutdown to bring fans at normal levels and yet average temperatures were around 50 - 55 °C.
Eventually got apple to replace heat sensors - this did not help - still got the same unwanted result, fans reving up to 4000 rpm and not stopping and all that without going above 60°C. I was at the stage to demand a complete replacement but decided to give it another couple of weeks testing.
Last test, a complete reinstall of the OS and this time, without any other software apart from standard software delivered with the mac. Ran a few things like importing over 10,000 pictures with iphoto and some other stuff to increase activity - overall CPU usage was at 5% idle for a good few hours and could not reproduce the problem (istat nano was not installed, so I could not monitor temperature). I started installing Paragon NTFS for mac and ran the same scenarios and still no fans going crazy - putting my hands over the top of the imac, can feel a slight breeze...).
Installed other software such as VLC and Firefox 5.0 but still no istat nano and same high activity, import high volumes in iphoto and also did an empty secure thrash to increase load. CPU usage was to 95 again and still fans are behaving properly.
One thing that comes to my mind with istat nano is that, when the fans get going, the ambient value change to -140 - I do not want to rush into any conclusion but is it possible that there is some interference between istat nano and those new sensors that have come in with Imac mid 2010 (from reading mac forums, Apple has added a new ambient sensor..). Because all the time I have been reinstalling the OS, I have always installed istat nano to monitor temperature and fan speed and I always got this issue. But since yesterday, I have installed clean OS, tested, added some 3rd party software but still no istat nano and I canot reproduce the issue. I have been using the same scenario during all this testing - very high import with iphoto, viewing a film, empty secure thrash, enough to use up to 95% CPU.
Has anyone experienced this? I hope this is the cause of my problem because this mac is making my life easier at home compared to previous PC and also, I want to know that my hardware is not at fault...
I will keep you posted if I get the issue again - could be tempted to install istat nano and run the tests to see if the fans will rev up after this but not sure I want to go through another 4 days of just doing this...
regards
Philip

T430s fan noise and fan speed monitor not working?

Hi, I just bought this T430s from the outlet store. I noticed a rather loud fan noise and found out s lot of compalints about the T430 model. I guess the problem I have is not as severe as those T430 users (e.g. the noise may not be as loud), but I still want to monitor the fan speed. Here's my problem:
1. none of the third party software can show fan speed, they can only show the cpu temperature, such as speedfan and aida64.
2. I tried to download the fanspeedcontrol driver from lenovo, but after installing it, the task manager does not show that the fanspeedcontrol exe. is working.
I do not want to change the fan speed, but just want to monitor the speed so that I can have a better understanding of whats going on. Does anyone have the similar problem?
Thanks.

Hi Alan, (I know this conversation was from several months back),
I don't know the answer to your questions. It seems that your fan is operational, as far as its most basic functional requirement.
I don't have experience with any particular software programs or widgets that indicate fan speed, sorry.
Do you have any view, through software, of the CPU (and GPU?) sensed temperature? Those would be very good data to observe.
If it were either disconnected or non-functional, I assume that your computer would report a POST error right after power-on (and self test).
But I just wanted to suggest here that in an unfortunate possible scenario, consider if the thermal grease on the heat sink(s) was inadequate (or was missing), then the fan would be running higher than normal (probably always spinning at a high rate), and it won't be taking enough heat away from the processor(s), i.e. inadequate cooling.
Which could be corrected by a technician (or DIY). This is pure speculation, it is not a definite, at all.

Monitoring CPU/chassis temperatures on a first-generation x2100 (no SMDC)?

We have a first-gen x2100 that does not have a SMDC; its bios is fully up to date (v1.1.8). We'd like to be able to monitor system temperatures (and, ideally, fan speeds). This seems reasonable, especially since CPU and chassis temperatures as well as fan speeds are reported in real time in the BIOS. We're using OpenSolaris 2008.11, but all of the "tutorials" and command references I've found online that indicate where temperature and other info might be found yield no useful information (or an error) on this system:
prtdiag -v ==> no temp info
smbios ==> no temp info
ipmitool str ==> "Could not open bmc device: No such file or directory; Unable to open SDR for reading"
batstat -t ==> "No thermal zones."
I've not found any mention of the SMDC being required to access thermal info, but is that the case? The BIOS is able to monitor temperatures and fan speed, so it seems reasonable that userland tools should be able to do the same. FYI, I've not yet tried the ILOM at all; I'd like to be able to access this info in userland.
Any thoughts?

Yes, I know the SMDC can be used to monitor those sensors, but like I said, we don't have an SMDC. The sensor readings are clearly available from the BIOS, and it seems reasonable that they'd be available without the SMDC.
If that's not the case, that seems to be a pretty poor design decision (it's been many years since I've seen a computer [even very low-budget desktops] that don't make available temperature readings to capable operating systems, etc). Clearly something that's been addressed in the x2100 M2, but unfortunate nonetheless.

Temperature and Fan Speed Terminal HELP

So, I've been browsing the interwebs looking for a solution to my problem of monitoring temperature and fan speed within the OSX Terminal, while I do have a functioning way of determining them, it does require third party software that I personally would like a different way. Does anyone know of a command that I'm able to locate either of them? I know ioreg previously was able to locate these, but currently I can no longer grep my way through to locate any mention of them. If anyone has any ideas, please let me know!

You might consider the Ruby gem iStats. Ruby was updated in 10.9.3 to v2.0.0p451, and iStats does work with this version. This information is newer than on his github site.

Is there any way to monitor CPU temp without Dual Core Center

I hate Dual Core Center it has done nothing but lock my system up is there any alteranative to monitor CPU temp/Fan speed

Quote from: Maesus on 21-March-07, 23:34:06
I use speedfan... but for Core 2 Duo, I don't think I have to worry about the CPU temp anymore... they are really coooooooooooooll
Does anybody have an idea what the optimal temperature range for core duo cpu:s are? I used to have an Athlon XP, which was typically 65 °, now the my E6600 is running at 35-40 ° [celsius]. But where's the critical temperature where it burns?
