CPU/GPU temperature monitoring

I have a T400-2764CTO ThinkPad and am interested in monitoring temps in the task bar area.
Any experience with freeware tools that have been successfully used for monitoring temps on the T-series? I'm aware of Tpfancontrol, but I'm not interested in controlling fan speed, just want to conveniently monitor CPU/GPU/HDD temps.
Thanks...

Is there an utility for monitoring cpu/gpu temperature and fan speed for desektop m9200T?

My desktop computer m9200T running Win7 Home Premium crashes often. It seems to be temperature related.
I had tried SpeedFan, but my computer crashed everytime I ran it. SpeedFan window scrolled 20 some lines of text than the computer crashed. Is there an utility for monitoring cpu/gpu temperature and fan speed for desektop m9200T?

Hi,
Only have one temperature monitoring application running or you could end up with erroneous readings.
Try PC Wizzard. Depending on your hardware, you should see temperatures for CPU, GPU and disk. At the same site you can also try HW Monitor.
I am running a custom motherboard and it comes with its own software for this purpose. HW Monitor seems fairly complete.

T420 CPU/GPU Temperatures seem excessive...

I was running Prime95 to check my CPU (Core i5-2520M) temperature (using Real Temp) and I noticed it was a bit high, about 95 degrees celsius. I followed up by running FurMark to check how the NVS 4200 GPU was doing. It ended up sustaining at 87 degrees celsius. I did not run the two tests concurrently.
I decided to strip the heatsink off and apply new thermal compound. After the new compound was applied, the CPU temperature under Prime 95 peaked at 84 degrees celsius. Under Furmark, the GPU sustained at 75 degrees celsius. A very significant drop.
I decided to run the two tests concurrently (after new compound had been applied) and ended up with a CPU temperature of 100 degrees celsius and a GPU temperature of 97 degrees celsius. Pretty horrifying stuff. I can't imagine those values being within operating range.
These torture tests are rather extreme so I followed up with some gaming. I played DOTA 2 for about 3 hours and during that period my CPU peaked at 98 degrees celsius with an average temperature of 93 degrees celsius. I did not log the GPU temperature during this session.
I should mention that Turbo Boost is enabled and the fan was set at maximum speed.
Does anybody have any temperature figures for similair configurations? Specifically in situations where the GPU and CPU are both under high load. I'm curious to know if my temperatures are abnormal.

I started to think that it's not an issue with my sample. I went ahead and confirmed these temperatures on two other identically specced T420s (4178). Under extreme conditions the heatsink/fan unit cannot dissipate heat quickly enough causing both chips (CPU and GPU) to reach dangerous temperatures. If you haven't torture tested the GPU and CPU in your T420 concurrently, you might want to give it a shot. It gets alarmingly hot.

High CPU & GPU temperature with ATI 4870 Graphics card

Hi I have replaced the original FX1700 card with an ATI 4870 on my S10 and I found the GPU temperature constantly floating at around 58C with no program running and the temperature of the CPU have also gone up to 47C with no programing running and 58C with program running(The temperature of the CPU was fine at under 40C before ATI 4870 was installed). Is this situation normal?
P.S. I have not replaced the orginal fan came with my S10.
Thanks very much for your helps

How to monitor GPU temperature?

Hi dears.
Recently I changed my HD3870's fan with the Arctic Cooler Accelero S1 Rev.2 silent cooler. This is much more silent than the stock fan installed on the Video card.
So the question is: how do I monitor GPU temperature to check if all is ok? In the event of too much hot GPU can I cause problems to all the system or only to GPU?
Thank's a lot.
Regards.

I use this app to monitor my iMac's overall temperature: http://www.macupdate.com/app/mac/23049/smcfancontrol
If the computer appears over 120ºF/130ºF, you can use the slide bars to increase the fan speed. Mac computers can still pretty easily run at around 210ºF, but the cooler you keep it, the better. Personally, I keep my iMac at roughly 100º.

T61 CPU/GPU 90°C during load, 70°C during idle, normal?

Hi!
I have a Thinkpad T61 with the following specs:
Intel Core 2 Duo T7300 @ 2.0 Ghz
2 GB RAM (2 x 1GB) DDR2 667Mhz
nVidia Quadro NVS 140M 128 MB
120 GB 5400 RPM HDD, Windows XP Pro.
It's about 6 months old, and recently I installed a temperature monitoring program on it and noticed quite high temps on both CPU and GPU. About 90 degrees Celsius during load and about 70 degrees during idle. I've opened up the computer (palmrest + keyboard only) and use compressed air to try to blow out dust from the cooling assembly. But there was hardly any dust at all. And the temps are still the same.
Is this normal? Anybody else have these kind of temps?
Thanks in advance

I got my thinkpad back today. They changed the fan for me. Now, the results.
The CPU now idles around 50 and during load about 60°C, I'm happy.
But the GPU is still the same, about 70°C idling, reaching around 80°C during load.
Is this still normal? Although I just mentioned the CPU overheating to Lenovo Support, I thought the cooling system covered both...
I might just buy a cooling pad.

Re: CPU core temperatures

I just received my laptop back from being serviced due to GPU overheating. It seems fine now in that department, but it would appear that the company which Toshiba employs to service computers in Sweden messed up elsewhere. Now my CPU core temperatures are even higher than before, fluctuating from 50 C (centigrade) when the computer is idle, to quickly rising to 80-90 during processor load. When I play, for example, Batman: Arkham Asylum, CPU 1 is 99C and CPU 2 104 C.
It would help me a lot if some of you guys would tell me what temperatures your computers run, CPU-wise, during heavy loads and also how quickly temperatures fluctuate between high and low temperatures. I just need to open a minor application and my CPU temps spike from 50 to 90, as mentioned above. I can't see how that is acceptable. I just might have to send the computer back, and it took them over 3 weeks to fix my first problem.
Best regards,
Johan

Thanks guys. I am using Toshiba drivers and the notebook is placed on a clean, flat surface. What concerns me is how quickly the CPU heats up slightly over 100 degrees centigrade. We're talking about less than a minute, and sometimes only a few seconds to reach 90. The GPU is fine after the service I mentioned in the original post.
However, I really appreciate your feedback and I will get that device to clean out dust. :) Oh, and I spoke to Toshiba's support and they said they can't discuss results yielded by 3-rd party software, such as Nvidia's System Monitor. Instead I am to stress test the computer, battry fully charged, and see if it turns itself off after having suffered high temperatures long enough.

No temperature monitors for Intel Macs?

I found the below in the FAQ for the application 'Temperature Monitor' and thought it might helpful to understand why we don't have a temperature monitoring application, or perhaps never will. SInce we do have the speedit.kext way to read CPU temperature, perhaps at least that is possible to implement in a standalone application.
Q: I am using the latest release of the application which should support my computer, but still no sensor at all, or only a S.M.A.R.T. hard drive temperature sensor is found. Is this normal?
A: Unfortunately there are some specific Macintosh systems which don't allow that sensor values can be read out by a normal application program. There are two different cases:
The computer uses a self-contained cooling control system. The hardware itself controls its own monitoring. No transfer of data from the sensor to the operating system is possible because there is no bus connection between the sensor and the actual computer.
The computer contains sensors accessible via a data bus, but cooling control is independent of Mac OS X. Apple does not provide any device drivers which would allow application programs to get data from the sensor. Only the firmware or a closed part of the operating system core has access to sensor data.
In both cases, it is not possible to develop an application program which could read out sensor values. The following Macintosh systems are affected by this problem:
PowerBook G4 Titanium (all models)
eMac (all models)
iMac G4 (all models)
Mac mini (all models)
Note that Intel-based Macintosh systems use a special mix of the mentioned monitoring techniques: Mac OS X only uses the load sensor of the graphics chip for thermal management. This sensor can be displayed by Hardware Monitor without any problems, it is however not displayed by Temperature Monitor, because this sensor does not measure temperature.
All other sensors in Intel Macs are controlled by special hardware working independently of the operating system, the Apple System Management Controller. This device has not been disclosed by Apple. There are neither drivers for Mac OS X, nor any documentation, and all details related to the function of this chip have been "censored" by Apple in the source code of Darwin. For this reason it is currently impossible that any application program could get readings from this chip.

"Mac OS X only uses the load sensor of the graphics chip for thermal management"
Yes and no. But, this doesn't really seem to be the case! If this is true, simply running Quake4 SHOULD cause the fans to kick on as the GPU is being heavily used. This did not happen on my machine. Only after reapplying the thermal paste would both fans kick in during heavy use. My guess is that it is actually a mix of conditions that cause the fans to operate at different levels. Heat pipe temp + GPU load + ...
I think one variable that is not being used is processor temp. I can't really understand why not though because that would go a long way to alleviating some of our heat problems and the fans would operate in a semi-normal fashion even if the processor/heat pipe connection is suboptimal.

Temperature Monitor for OS 10.3.9

I need an application or console command that will show me the temperature of my CPU.
I'm running a Beige G3 that is using a G4 processor. It's running OS 10.3.9 through the use of the application xPostFacto. I've found the apps "Temperature Monitor 4.8" and "Hardware Monitor 4.8," but those don't support any Mac OSs below 10.4.x. Temperature Monitor 4.7 supports Mac OS 10.3.9, but I can't find a download of it for the life of me. All of the links redirect to version 4.8.
Please, any help would be much appreciated, my project is at a stand still until I can find something that works.
Thanks!

Click on my TMM name at left & send me an email. I'll send you the 10.3 version. Don't know if your Mac has the sensors to monitor the temps.

Best Temperature Monitoring Program?

Hey all, first time posting in the forums.
I recently got a mid-2012 MBP for college, so of course I immediately began putting games like Borderlands and GTA:SA on it. It runs anything I throw at it beautifully, but it gets awfully hot while it does. I know this is common for MBP's, even up to 90 degrees celsius, but it is something a tad worrisome when it gets over 80 (some games get it there every time....). So I've been trying to monitor it to at least be sure I'm not letting it get up there too often or for too long.
So had a few questions about temperature monitoring with Macs. I've currently got 3 programs running monitor temperature and system usage- System Pal, iStat Pro, and SMCfancontrol (which I also kick up a bit when playing the more GPU intensive games). The problem is that all three show different temperatures. Right now SystemPal reads 41 degrees celsius, SMCfancontrol reads 49, and iStat Pro has temps between 30 and 42 degrees. Which one's right? Is there a more accurate/definitive program for temp monitoring?
If it makes any difference, I usually play projected onto a 32 in LG TV using a thunderbolt to HDMI. I know this is more GPU intensive to begin with, but after going HD it feels a necessary evil.
If anyone happens to know of ways to keep temps down while gaming, monitor temps during full screen apps/games, or ways to monitor GPU usage (right now I have none ) I'd greatly appreciate advice on that too!
Thanks so much for answers!

Try iStat Menus 4.02 or Temperature Monitor 4.96 or Hardware Monitor 4.96.

Internal temperature monitoring utility?

Is there any monitoring software (similar to Activity Monitor) that detects whether key components such as the CPU and hard-drive are running at a reasonable temperature or are overheating?
I believe that temperature-monitoring sensors are present inside the casing so in theory what I am asking about should be possible.

Hi, KDS-KDS. My experience has been that temperature-reporting utilities such as the one linked by roam above (which I've tested) are only able to find a single sensor in my Tibook, the same generation as yours. That sensor watches only the hard drive, which is normally one of the cooler parts of a Tibook. Though there clearly are additional sensors in the machine, it appears that their output is unavailable to (or perhaps isn't readable by) such reporting software, for some reason. Owners of other Mac models have reported quite varied results, from highly satisfactory (several sensors detected) to no sensors detected at all.
This question came up several times in the Tibook discussion forums a while back, and my recollection is that no Tibook owner, regardless of which of the four generations his machine belonged to, ever found any temp-reporting software that could provide a readout on the CPU. If you do find one, please post in over there and let us know.

Where are temperature monitoring components on K9N Platinum?

Where are temperature monitoring components on K9N Platinum?

Ok it appears that with current systems there is no mbrd mounted CPU temperature thermistor. There are two thermal sensors inside a K8 CPU: one is a simple thermal diode for use by external circuitry, e.g. a hardware monitor or Super I/O chip and this is the temperature you will see as measured through that monitor chip; the second is used internally by the CPU for software and hardware thermal management so includes the circuitry to translate to a temperature reading. This second sensor is associated with the THERMTRIP Status register where the diode measured "current temperature" is stored in bits 23-16 (23-14 for Rev G); now in pre-Rev F CPUs that field is documented as "reserved" but it does appear to have the temperature stored in it since Speedfan reads it and reports a valid(-looking) temperature. So with Speedfan you can get two CPU temperatures reported which behave somewhat differently, probably due to different calibrations of the sensor circuitry. One is read through the hardware monitor chip; the other is read directly from a CPU register.
What I'd like to know is if there is anything at all under the CoreCell box? In my system it is certainly not the Winbond hardware monitoring chip which is clearly visible in another area of the mbrd. Does anyone have a dead mbrd they could rip the CoreCell box off, just so we know what is hidden there?

Any native extension for checking memory and cpu/gpu usage of ios and android?

I need to be able to see how much memory/cpu/gpu an app uses while running for ios and android.

Hmm, maybe it can be done with code already included in flash and adobe air, it seems... donno.. found stuff like:
freeMemory

Runtime Versions:
Flash Player 10.1, AIR 2
The amount of memory (in bytes) that is allocated to Adobe® Flash® Player or Adobe® AIR® and that is not in use. This unused portion of allocated memory (System.totalMemory) fluctuates as garbage collection takes place. Use this property to monitor garbage collection.

donno how to use it...

Is my temperature monitor working correctly?

i've downloaded the marcel bresink temperature monitor for my macbook.
before the firmware update, it ran at 67 degrees celsius. after the firmware update, it runs at 40's.
when i restarted my computer few hours later, and loaded up the temperature monitor, it gave me a reading of 29 degrees and even with intensive work (where i can feel the heat and the fan working) the temperature monitor still remained at 29 degrees. right now, it seems to be stuck on 25 degrees. i've changed the preferences so that the sensors are updating the temperatures regularly. i've also tried reinstalling it. is there something wrong or am i not noticing something here?
thanks guy!
btw, my new macbook is working great!

It's an Intel processor design fault. I got this info from the Hardware Monitor developer.
Q: I have a Mac with an Intel Core Solo or Core Duo processor.
Sometimes, the temperature readings seems to "hang" and are no longer
being refreshed. Is this a problem with the application?
A: No, this problem is caused by an internal design flaw of current
versions of Intel Core processors. The Digital Thermal Sensors may
stop working when the processor returns from a C3/C4 power saving
state. Intel plans to correct this hardware bug for future steppings
of the CPU.
Intel refers to this hardware problem as Erratum AE18. For detailed
information, please see Intel document 30922204
