Cpu temperature without fancontrol

Hi, after i installed mavericks, awesome! i clean up my mac and i removed fancontrol.
now, whit fancontrol, the cpu temperature in idle is 40-45 c°, fan rpm abot 3000-3500 and when i open a game, the temperature reach about 80 or more but immediately the fan rpm change to 5500-6000 and it's ok.
whitout fan control, the cpu temperature in idle is 50 c°, fan control always 2000 rpm and the same try with a game, the fan rpm change to 6000 very slowly after the cpu temperature reach 90-95 c°...
i had that problem since i bought this air then i ever kept fan control!
of course now the battery reach 4 and half hours or 5 than before with fancontrol (2 and half hours), but are you sure it's not dangerous?!

You call it a problem. I don't see a problem.
Not only are you are not exceeding the safe operating temp, but it is entirely expected to hover in that area for many types of games.
While not a "gaming rig", the Air is quite competent for many gaming purposes. Just don't expect it to leisurely lope like a Macbook Pro. The CPU will indeed be pushed rather hard in these circumstances. Sure, you may be able to push the fan harder, and acheive a slightly lower operating temp, but I don't see the point.
The fan itself, being a moving part that you can't do much to maintain, is something I'd rather preserve UNLESS the temps were so high, and my need so strong, that I just had to push things beyond the stock cooling system's effectiveness.
Your worries, pertaiing to your post here, are rather unfounded.

CPU temperature utilities...

I've used three different utilities to check CPU temperatures (Core 2 E6600, the heatsink is Zalman 9700LED):
pcAlert4
Core Temp v0.94
Intel Thermal Analysis Tool (TAT)
The Orthos Stress Prime provided 100% CPU utilization in addition to TAT. All three of the utilities showed different temperatures under the same load; Intel's TAT showed the highest and MSI's pcAlert4 the lowest temperatures. That's fine, although MSI really should get their own stuff right.
I've also noticed during testing that it doesn't make much of a difference, if the Zalman heatsink's fan runs at low, or high RPM; well, other than noise factor. The differences between the low/high RPMs from the temperature's perspective are 2-3 degree Celsius the most for both idle and 100% CPU utilization. That's hardly a reason to run the fan at high speed, especially when the temperature tops out at 55 degree Celsius with 100% CPU utilization for a prolonged time. At idle time the temperature of the CPU is around 32 degree Celsius, depending on which utility is red.
Is this normal for the Core 2 CPU, or neither of the utilities show the actual temperature of the CPU? I'm leaning toward the latter one.
TIA...

Eeh.. warning. When I stopped my CPU fan my computer eventually crashed because Jmicron got screwed by heat and all my IDE HDDs disconnected while in Windows.
It took a moment to get Jmicron to detect HDDs again after shutdown, and once after that drives disconnected again in windows. Now it seems to work ok.
Tho maybe because I didn't bother to close my computer case, and that side panel has 2x120mm fans mounted on it, so there was only PSU's cooler running
Well, thanks for the warning; I did close the side panel, after I disconnected the heatsink's fan
I don't use JMicron; the four SATA drives are connected to Intel's controller. Additionally, the drives are in a separate compartment from the motherboard with it's own 120mm case fan to cool them.
The CPU temperature without the heatsink fan is 34/32 degree Celsius for core 1 and 2, which is just couple of degrees higher than with the fan running. Maxing out both cores to 100% with two instances of Ortho Beta running raises the temperature to 52 and 50 respectively. Playing GRAW without the heatsink fan running results in around 48 degree Celsius, which also just couple of degree more than the heatsink fan is running.
My initial suspicion of the two 120mm case fans around the heatsink are the reason why it doesn't really matter at what speed the heatsink fan is running at was correct. Yes, the case panels were in place and the three 120mm case fans and the power supply's fan were moving the air evidently rather well.

And if you are just curious. You will find some screen captures from my testing in this thread. (bottom of 1st page).

Nice experiment, which probably would've been better if you close the side panel.
My machine is still running just fine without the heatsink fan; the Zalman 9700LED is pretty darn good, it can keep the CPU at normal temperature without its fan. The Antec P180 case helps a lot, it has great airflow and not even noisy.
Well, this was fun; time to turn on the heatsink fan. I just feel better if it is running...

Mac Pro 8-core X5365 CPU temperature

I've got an 8-core Mac Pro which is crunching SETI@home 24/7, with Hardware Monitor monitoring the CPU temperatures and other vital stats. After reading the Intel Quad-Core Xeon Proc datasheet, I'm a little edgy about the operating temperature of these X5365 CPUs, currently registering at 65 - 70ºC on load for each temperature diode, and fail-safe temperature set to 73ºC to disable SETI@home via Hardware Monitor. I also have smcFanControl speeding up the fans because my ambient temperature varies thanks to myself being in a tropical region, my ambient temperature can reach 33ºC at times, but down to 28ºC when air-conditioned.
My question is, what is the maximum temperature for these CPUs before they run into the risk of being fried/permanently damaged..?
Inputs from the Mac Pro-DC/grid community are also welcomed here.
Thanks.

my 8-core is running seti 24/7 since may without any problem, although my ambient temps dont rise above 30 degrees centigrade...and that's using the optimised apps which make the processor run hotter
the fans on the machine run 600-2000 rpm all day and all night, i dont expect it to lessen the life of the machine whatsoever. it should be capable of running flat out all its life, that is, after all why we spend so much on these machines in the first place !
if you only use 4 cores perhaps you should buy a 4-core mac ? he heh just joking...
as mentioned earlier, when things get really too hot the OS will shut the system down, and if that doesnt happen then the cpus themselves will shut down...
the heatsinks and fans on these machines are fully capable of coping if your macine is running withing the specified ambient temp range which for the mac pro is 10° to 35° if your seeing ambient over 35 then smc fan control is probably a good idea otherwise it should be fine

If you wanted a 100% perfect cpu with twice as much cache memory (compared to yours), I could probably get you one for about $10 delivered to your door (more or less depending on cost of postage). I can certainly understand why you wouldn't want to waste your old chip, but someone using a slower chip might be willing to pay $5 for it, so it wouldn't be a complete waste.
These are chips that originally cost hundreds of dollars and the way I see it is as cheap as they are selling now, I can't afford not to upgrade. Generally the fastest chip in any line are quite expensive even after a few years, but the models we are talking about end up being so cheap that they are destroyed in order to salvage $1-2 of gold from them.
However if you're happy with your performance, then there is no reason to upgrade.
There is one other aspect you may want to consider, if your system has the newer version of system board that supports Penryn cpu chips, then you could get a more advanced cpu chip that runs cooler, since you're concerned about running temp. If your laptop was manufactured in 2008, then it's very possible it could have a board that supports the penryn class cpu.

Macbook Pro Retina Late 2013 CPU temperature issues while gaming (99 celsius) Is this normal ?

Hello everyone, this is my first time here. I recently purchased a macbook pro retina late 2013 notebook just over a month ago. It seems to be working just fine. I've installed bootcamp and installed windows 7. I use Speccy for my temperature monitor. I've played DayZ Standalone as well as L4D2. I noticed while playing both games on their lowest settings the CPU temperature consistently stays in the 90 degree celsius range often reaching 99 degrees celsius. I am fairly tech saavy and have a decent knowledge of computers.I bought the ThermaPak Heatshift pad in hopes of cooling it down but to no avail as it only does a great job at cooling everything else. This is my first laptop so I treat it like my baby ! haha I was wondering if these temp readings are normal because I know that even reaching 70 celsius can be somewhat damaging. Thank you for your assistance.
EDIT:
I've attached a screenshot of the temperature for proof

So I just got back from the apple store and wow, what rude service. The guy basically shrugged when I told him "Well, I guess Im stuck with it huh?" after he told me there was no way I could get a refund. He performed a test and told me everything was fine and told me in a very arrogant manner that the test isn't showing the results I told them about as if I was lying....***? He said they can send it away for a few weeks but I don't have any other computer and I just bought this one for school so I can't afford to have it gone for that long. He told me "doesn't your school have a computer lab"? Seriously, how can someone at Apple be this rude? I told him they do but its closed at 7 and I dont live on campus. How could a computer lab replace a personal computer? He basically kept shrugging rudely anytime I tried to find a solution. He didn't even reply with a single word. When I told him I called the call center and they told me that yes it is much too hot and to take it to the store after doing a fix he just chuckled and rolled his eyes. Really? I spent 1500 dollars on this computer to not even be able to do basic things on it without it overheating and the service is this bad? Well, looks like I won't ever be buying an apple product again even though before this experience I was a huge fan of all their products. I know one customer doesnt make a difference to them but come on...looks like I'm stuck with it and apple couldnt give one care. If having your hands uncomfortably hot after a small amount of time is acceptable then it looks like I'll never be buying another laptop from them. Its a shame I really liked it at first.

Read clarkdale cpu temperatures

Hey everyone,
is there a way to read the cpu temperatures of clarkdale chips like the i3-530 i'm using? It seems to me that in 2.6.32.9 there is no kernel driver available to access the sensor information. Does that mean there's no way to read the temperatures?
So far I've tried lm-sensors and of course i looked at thermal_zone in /proc/acpi/ without success.
Thanks,
demian

Here is a solution that reads the temperature via a VBS script. The script uses WMI to access the Temp.

X2100 max CPU temperature

Hi all
Searching the SUN docs all I can find for the x2100 (mark 1+2) is the 'operating temperature' of 2-38 Degrees C. I'd like to be able to relate this to the results I get from the internal IPMI sensors- CPU and case temps.
Does anyone know the reccomended max / min temperatures for the CPU and case temp?
I know the cpu shut down safety is at 80 Deg C but I'd like to know what's the max they can safely run at for a prolonged time without damage?
What's the max temp's you'd run your x2100's at constantly?
Cheers for any repsonses :)

Look up AMD's web site for max CPU temperature for your model of CPU. The critical thresholds are wrong, the CPU max temp is definitely way lower than 80 degree C.

Normal CPU temperature range

I'm curious if anyone knows what the normal CPU temperature range is for a Macbook? I just installed istatpro so I can now check it. The current CPU temp is 140F and the fan is at 1,500 rpm. At what temp does the fan kick into a higher speed?
Thanks for the help.

The normal range is about 30º-85ºC depending upon CPU and GPU loads. Maximum is 125ºC at which point thermal shutdown occurs (your machine will shut down.) The fans change speed with temperature according to a hard-coded table (not firmware encoded.) The older Core Duo laptops such as yours have a lower fan idle speed than the newer models. Although not supported by Apple you can install third-party software that can be used to increase the fan's idle speed - Fan Control or SMC FanControl. Use at your own risk. The subsequent laptop models now use an idle speed around 2,000 RPM which tends to keep the machines a little cooler. However, this has no effect on when the fan will ramp up to higher revs. The software only raises the idle speed.

Faulty CPU temperature sensor

Hello,
I am sorry if this is covered already in another topic.
Today I went to the local Apple service center to give my MacBook Pro 15 (OS ver. 10.6.8) for maintenance cleaning and a change of the thermal paste of the CPU. I got a call a few hours later and a technician told me I need to change my mother-board, because the heat sensor of the CPU gives incorrect temperature and the FANS start spinning at 6200 RPM without the processor to be loaded so much. (The price was too high ofc)
Well I know that if I start a graphic software or a game then the temperature and the fan speed rise but thats perfectly normal and logical. Though I have seen it many times the moment I start a game, temperature softwares like: Fan control or IStat Nano show around 30 or 40 degrees increase for just a few seconds which is not possible. And vise-versa the moment I turn off a game it drops to 50 or below degrees. I tried something else - turned on the laptop after it was cooled down to normal room temperature and started - Parallels Desktop /Windows XP then Heroes of Might and Magic V and loaded a saved game without actually doing something, just to check the sharp increase of the CPU temperature...it shows 108 degrees, though the body of my laptop was perfectly cool (where the CPU is placed). I think is impossible to generate such heat in just 2 seconds. The interesting thing is that the moment you stop it it drops to 45 degrees.
Please advice if you have any ideas. I can not afford to change my MB at the moment and the laptop guarantee has expired 1 year ago.
P.S I was thinking to increase the upper threshold of the Fan Control (now is set to the default of 80), though I am afraid to speculate with this...

If your cpu tries to exceed it's maximum rated temperature it will immediately shutdown (crash).
Just because you have Parallels at full screen does not mean that other applications stop running. Everything that was running before you went to full screen for Parallels continues to run in the background.
Graphic intensive games can put a very large load on the cpu. They can also draw power from the battery while using AC power.
Your fans should be idling (2000 rpm) when the temperature is less than 70 degrees C. Somewhere between 70 and 75 C they should begin to speed up. A 100% sustained load on the cpu will have the fans at maximum rpm as long as the load continues. If your MBP can handle this sustained load without shutting down the heat transfer from the cpu is correct.
It is very unlikely that the temperature sensor for the cpu is bad since it's part of the cpu chip.

K9N Platinum - Wrong CPU Temperature in BIOS

Hi, I have a K9N Platinum (7250-020) with the latest 1.3 BIOS and an AMD X2 3800+. The CPU Temperature in the BIOS has a negative sign in front of it, and it seems to always report -48*C. I tried the latest nVidia nTune and it was reporting the CPU temperature to be 208*C, which is absolutely impossible...
Does anyone have the same problem? I searched around and it seems I'm not the only one, but I still cannot understand if it affects only some K9N Platinums or all...
Thanks.

I assume you are talking about checking voltages as reported by the BIOS in the HW Monitor page, not physically checking them with a multimeter, correct?
I'll take a look at the numbers in the BIOS, but last time I checked they were ok.
As for raising the issue with MSI, eventually I will, even if they ask you soooooo many questions (for good reasons, I know...) that it would take me half an hour to fill that form...
I've checked with both and software is a little out from what a multimeter state's. Only check with a multimeter if your happy to do so. http://forums.extremeoverclocking.com/showthread.php?t=137886 offer good advise if using a multimeter .....
The only issue I see is the AUX connector for 3.3v with ATX2.0 spec (Modular cables etc)

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 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?

High CPU usage without any application running on the laptop

Hi ,
I saw some earlier posts as well but I am not sure if anything is helping me. I have a HP Pavilian Dv6. Its with me for now since 2009 or so. It was all running very well till last Nov - Dec 2013 timeframe. I had many bulky work done on the laptp like video cutting editing , along with audio edits , fairly well. I used it mostly for videos and no games though.
Since Nov - Dec 2014, all the videos started slowing down, extremely jerky, and not catching up with the audio. Slowly the problem became worse . After 10 mins of video it just stopped and hanged. It did it with every site and any format of video including videos on my C Drive. I earlier tried a lot of things, playing around with flash player thinking that's the culprit. Did not help. Browsers changed, Mozilla, internet explorer , Chrome, everything no change. Then till around last week, I tried tested, uninstalled a lot of programs, also did Microsoft system restore and seen , the CPU continously behaved reaching to its 100% peak and the videos getting shot down. Just no change. Last week , I got desperate and finally reformatted my hard drive and did a factory restore on the laptop. IT DID NOT HELP !! The laptop behaved really like a good puppy for a few days , Youtube and what not and again since yesterday it has been shot down ! No videos will run. What's more even a DVD video is not running , nothing on a browser a simple DVD player DVD play is not running. Jerky videos and hanging issues.
Everything boils dows to 100% CPU usage. Even if I am closing all my applications , it shows 'system' as the process using 90-100% CPU. Without any browser or even a notepad option open. There is also a prgram 'dwm' which eats up the next big slot of CPU.
I am really tired of this and not able to enjoy anything. Please suggest what could be the issue here and how can it be helped?

Just to add the laptop is HP Pavilian DV6 , model Dv6t - 1300.

My macbook pro cpu temperature is too high??please tell me correct fact and information

i mistake deleting my activity.......re question...
I'm using macbook pro retina 13inch 2013 late version.
my macbook has NO external graphic card, just iris graphic.
when i was playing diablo3 or watching movie by using bypass ip address, my cpu temperature was maintained 90~100 celcius degrees.
And at the same time, my cooling fan was maintained 5800~6000 rpm.
There are two questions.
One, is my macbook temperature too high or normal level ?
Two, i know that 6200rpm is maximum speed of cooling fan. Why did fan run 5800~6000rpm, not maximum?

When processor intensive activities are taking place, temperature may reach the maximum level.

How do you check CPU temperature w/o using Bios?

I saw many many posts about this and just want to make sure I get the correct software to do this (If I can) I'd like to be able to check my temperature without going to the BIOS.
Motherboard K9N2 SLI Platinum
Windows Vista 64 bit
AMD Phenom 9950 quad core processor 2.6 Ghz
Nvidea Geforce 9800 GTX
I saw several references to speedfan but just want to make sure I get the appropriate one. I just got this PC and would like to check the temp over the next few days just to see how everything is doing. Thank You .

CPU temperature is too high in Solaris 10 sun fire v890 machine

Hi,
I just installed Solaris 10 on a sun fire v890 machine. I used the prtdiag -v command to check the system.
However, It appears to me that the CPU temperatures is higher than the temperature range specified in the technical specification. The server is a standalone node that does not connect to the network or process anything.
Is it a problem? Thank you.

Hi Rukbat,
Thanks for your reply.
I have displayed the verbose prtdiag -v on the v890 machine.
However, I couldn't find the hard-coded operational ranges. Could you please advise?
Hi Sun-worshiper,
I executed the command and couldn't find the targeted temperature.
