[solved] fan too slow, cpu temperature is 80 degrees

ThinkPad X200T | x86_64 | Linux 3.6.8.1-ARCH | systemd | gnome3.6.2
lm_sensors already installed, sensors.service already enable and start. I have read the wiki, but understandless. The wiki is Fan Speed Control and lm_sensors.
BUT the fan is too slow. It can't auto increase the speed
There is some code I use in the next.
$ sudo modprobe coretemp
$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +79.0°C (crit = +100.0°C)
thinkpad-isa-0000
Adapter: ISA adapter
fan1: 4877 RPM
temp1: +79.0°C
temp2: +0.0°C
temp3: +0.0°C
temp4: +0.0°C
temp5: +0.0°C
temp6: +0.0°C
temp7: +0.0°C
temp8: +0.0°C
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +80.0°C (high = +95.0°C, crit = +105.0°C)
Core 2: +79.0°C (high = +95.0°C, crit = +105.0°C)
I don't know why fan1's speed always above 4877 rpm.
$ cat /sys/class/hwmon/hwmon1/device/pwm1
255
In the next, only find out one driver is suitable. It's coretemp.
$ sudo sensors-detect

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):
Module cpuid loaded successfully.
Silicon Integrated Systems SIS5595... No

(driver `coretemp')
Intel AMB FB-DIMM thermal sensor... No
VIA C7 thermal sensor... No
VIA Nano thermal sensor... No
Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no):

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no):
Probing for `National Semiconductor LM78' at 0x290... No

Probing for `Winbond W83781D' at 0x290... No
Probing for `Winbond W83782D' at 0x290... No
Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):
Using driver `i2c-i801' for device 0000:00:1f.3: Intel 3400/5 Series (PCH)

Now follows a summary of the probes I have just done.
Just press ENTER to continue:

昨晚看了俩小时电影，关了播放器之后发现GPU温度飙到80多摄氏度。手摸在键盘上都能感觉到烧烧的，风扇出风口的铜片很烫手。为了小黑的健康，我决定折腾一下。
我的小黑是Thinkpad T61p，在装Ubuntu的时候相信是默认安装好thinkpad_acpi的，但是默认情况下，风扇的转速都是在“自动档”上的。要换成手动档你必须要在/etc/modprobe.d/下添加一个文件thinkpad_acpi.conf(老版本的可能是叫options)。在文件中要放：
options thinkpad_acpi fan_control=1
接着重载模块：
sudo modprobe -r thinkpad_acpi && sudo modprobe thinkpad_acpi
这样一来就可以直接通过修改/proc/acpi/ibm/fan来改变转速了：
echo level auto | sudo tee /proc/acpi/ibm/fan
cat /proc/acpi/ibm/fan可以查看如何命令风扇：
commands: level <level> (</level><level> is 0-7, auto, disengaged, full-speed)
commands: enable, disable
commands: watchdog <timeout> (</timeout><timeout> is 0 (off), 1-120 (seconds))
由此，可以根据你的需要来控制风扇了。
如果想要自定义自动化就有好多种办法了。一种比较简单的办法是直接安装thinkfan，在 /etc/thinkfan.conf修改好阀值和对应的转速级别（0–7 level值）。默认情况下，thinkfan是在deamon模式下运行的。不过有个缺点是好像它只能操控0–7的等级，不可以auto或full-speed。
还有一种自动化方法是使用自动脚本，但是我从源代码看貌似也只是能控制0–7的转速。
其实0–7或auto在常规任务的时候是足够的，温度一般在40–60度之间，但是像看电影这种损耗资源的任务就会开始升温。0–7的转速是不够的（level 7的转速应该只是3000多转吧），而且貌似这些软件和脚本检测的温度数据都只是CPU温度。所以几时GPU温度升到80度风扇还是慢慢悠悠两三千转……要解决这个问题其实也很方便。因为温度监测的接口就在/sys/devices/platform/thinkpad_hwmon/temp*_input，各部分温度对应的ID可以到这张网页上找到。
有了这些，相信写个适合自己小黑的bash code已经没有多少问题了。当然最佳还是利用现成的代码，稍作修改即可。

T60p CPU temperature over 80 degrees celsius

Hello, I installed Notebook Hardware Control and it shows a cpu temperature of 84 degrees (yes celsius!).
I can't put my notebook on my lap because it's too hot.
The fan is louder than it was in the beginning and from time to time it makes a loud noise (like when you're holding a playing card between the spokes of a bike).
The T60p gets almost always that hot, what could be the reason and how can I fix this (it still has warranty)?
Thank you for your answers.
Something additional: I'am not sure about that but it may be that the CPU gets only that hot when the power is coming from the AC adapter (my ac adapter indeed is making also some noise, it's like you could hear the power passing through, is that normal?)

Chris
PS the GPU temperature is around 90 degrees celsius as well..
Message Edited by criza on 02-21-2009 05:41 PM

Welcome to the forum!
Yes, these temperatures are very high and you should send the machine in for a checkup. The fan is likely on its way out or just badly clogged with dust.
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 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?

[SOLVED] KDE too slow on VirtualBox

I've installed Arch Linux on VirtualBox with KDE. At first I tried to install through 'pacman -S kde-meta' and, after seeing it was slow, I tried to do that through 'pacman -S kde-meta-kdebase', but KDE also is too slow.
For some reason I don't know, VirtualBox starts to load and load from HDD all the time. However, if I install XFCE, everything goes well.
Why?

* You're using LLVM with kwin compositing enabled
* VirtualBox is able to resize and adjust the window right. So I'd say that I installed the virtual GPU drivers.
* My host GPU works well with KDE, but I've only tried it in other distros. I don't know if kwin is enable, but I know I didn't change any configuration of KDE.

I saw there are more than one process using the HDD. (I used iotop.) So can I discard that Nepomuk is causing the problem?

How to solve the too slow reponse of gmail on ios 6 running iPad?

I got the very slow response problem of mail program of ios6 while using GMAIL.
Also i met the problem too slow response of Safari whlie using Google search engine.

It sounds more like the type of problem caused by "throttling" which might happen because of google's download limits, or local network problems.
But there are other potential causes.
1. What folders are downloading? (see the activity in Tools | activity manager)
2. Is the gmail account set up as imap? or pop?
3. what antivirus software are you running?

[SOLVED] 3D too slow, need help to find out why

Hi folks.
I tend to compile and use mesa from git. Most of the time I have no problems, but recently it all got screwed up. Everything was running fine, until suddenly, after an update, I could not play games anymore. Native or Win games using wine. They're just to slow. Like, 1 frame per 3-4 seconds. I've tried different kernel versions, different mesa versions, I inspected pacman.log trying to find what could be the reason of this. Nothing. Just to note, applications like Stellarium, for example, runs just fine (with vsyncing off it can achieve over 150 FPS), kwin effects run fine, video playback is perfect. But, as soon as I start a game like "World of Goo", or "Counter Strike" using wine - barely 1 fps. I have absolutely no idea what could be the cause of this. Please help!
Btw. all the logs are not displaying anything unusual.
Edit: using r600g (Gallium driver).

32 bit!

Try
LIBGL_DEBUG=verbose glxinfo | grep render
That output should be fine.
Try
LIBGL_DEBUG=verbose wine foobar.exe
and pay attention to the first few lines where it loads the driver. It should succeed with some driver from /usr/lib32/...
If this is so, then try
LIBGL_DRIVERS_PATH=/usr/lib32/xorg/modules/dri wine foobar.exe
If it then works, then simply your path is wrong.
All that is assuming that you run 64 bit and have lib32-mesa-full etc. upgraded too.

CPU temperature reaching 97 degrees C when Skype is running!

I've installed iSlayers monitoring app, and also smcFanControl (which I've got on HigherRPM to try to keep things under control), however, temperatures are still reaching upto 97 degrees C when running Skype with video or when Time Machine is doing a backup!
This seems frighteningly high, given that the laptop isn't really doing that much! I've never experienced anything like this on the non-mac laptops I've had before. Is this normal?!?

hi all,
maybe it's a coincidence , but : today i've replaced my hd with a segate momentus 500gb 7200 rpm and bizarrely my cpu temp is average 42°c while before it reached 100% while cloning my old hd to the new seagate which was in external enclosure.
i've also replaced my superdrive which was spitting out all medias refusing to read them; i've purchased the same model on ebay , GSA-S10N.
now everything seems cooler , weird ...

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.

Z68A-G43 - Bios shows cpu temperature incorrectly - noisy fan - SOLVED

Hi
I have i7-2600 + Arctic Cooling Freezer Pro rev.2 and when I use Z68A-G43 (G3), the cpu temperature shown in the bios is around 20 degrees higher ( 52-53 degrees C ) , than while I am using the same components on MSI H67MA-E35 or Asus P8H61M-LE/USB3 (30 -32 degrees in both cases ) !
I use the same thermal paste and the cpu & heat sink are definitely seated properly.
The on-board sensors are fine as when Windows is loaded, programs like HWINFO, PCWizard show the right, much lower temperature .
It wouldn't bother me that much since I know that nothing is getting overheated (the heat sink is cold ) ,however, the higher bios indications make the cpu fan spinning much faster ( 2000 rpms + ), I cannot slow it down thus I get a lot of noise coming out from it .
I updated bios to the newest 2.3 ( btw brilliant tool by Svet ) but there was no improvement, I still get the high temps and no option to control the fan.

Just checked again, Smart Fan works at the bios level too, so just the temperature shown is wrong (50-52) instead of ~ 30. I am happy customer now. Thanks again for your help.
This is pretty normal behaviour, my bios temp is ~40°C - 42°C, whilst in Windows the idle temp is ~25°C (depending all on ambient temps).
There are 2 reasons given, which one is correct or if they are both correct, I dont know, but they told me that in BIOS, the cpu utilization is much higher then in idle Windows desktop and/or it is as Jack already described, that powersaving options are not enabled in BIOS, but doing such a good thing in Windows, that the cpu drops its temps significantly.
The reason for the higher BIOS temp then others, can be in the cpu itself, some are just plain hotheads, or have flaky temperature sensors, for instance one core of my cpu will always be at 62°C max, while the other three peak at ~71°C, it just will not go over 62°C.

CPU fan speed too slow Core 2 Duo on 975x platinum

This is my first attempt at building a computer and things went good except for the CPU fan. The CPU, according to BIOS, seems too hot, idling at around 38 to 40c and loaded at around 45+ but I haven't used it hard yet. The fan speed when controlled by the mobo is only about 800 to 900 rpm when idling. I turned off the mobo control and the fan went to 1700. Surely this thing can turn faster than that, is there something I'm missing here. I really don't want to buy a different fan if this one will work. Noise is not a problem for me I just don't want to run the CPU that hot. Help!
Thanks,

Intel Core2Duo is using Thermal Throttling Technology,or in this case TM2 (Thermal Monitor 2) . This is the main part of Intel SpeedStep Technology. It can decrease the multiplier on a CPU and decrease the CPU voltage (vcore), thus lowering temps but reducing the clock speed of the CPU. This is only activated when a small amount of processing power of the CPU is actually required. Here you are some temperature specs for Core2Duo
Thermal specification:61.4°C
Thermal Design Power:65W
The thermal specification shown is the maximum case temperature at the maximum Thermal Design Power (TDP) value for the processor. So, you have a normal temperatures for the processor, and you'll have to get used to that low noise

[Solved] Asus L1366 mobo, cpu fan speed control

Hi, everyone,
I finally have this new core i7 system, to replace my old AMD athlonx2. I have one question about the CPU fan speed control.
I remember that in my old system, the cpu fan speed control works out of box, no configuration is needed.
But when I install arch 64 on this new i7 system, the cpu fan is running at its maximum speed constantly while the CPU temperature is modestly low. I know there is a wiki teaching how to do it.
However, I am just curious why it doens't work out of box any more? Does CPU fan control work for you guys out of box normally? especially the new Core i7 cpu users?
Please let me know, really appreciated it.
Thanks a lot.
Update: the issue is solved, see my last post, the solution is blacklisting: asus_atk0110, instead use w83667hg.
Cheers.

First off, it would be useful to know what the sensors-detect script actually reports.
Okay. How fan control works on Linux: First, navigate to /sys/class/hwmon
Each of these folders, i.e. hwmon0, stands for a sensors monitor / fan controller on your mainboard that may control one or several fans. Inside hwmonN, there should be a subfolder called device, which contains several interfaces if your BIOS allows software-side fan control. You can read them with cat and write to them with echo.
Examples:
pwm1_enable shows if OS-level fan control is enabled (1) or disabled and in BIOS control (0). Changing fan speed won't work if this is disabled. (i.e. cat /sys/class/hwmon0/device/pwm1_enable reports 0 -> disabled; you could enable it with echo 1 > /sys/class/hwmon0/device/pwm1_enable).
pwm1 allows to change fan speed. The values range from 0 (fan off) to 255 (full speed, 12V).
fan1_input shows the current RPM if a fan is connected. You can only read from this interface. Its useful to check all of these in the each of the hwmon folders to find out if there is actually a fan connected to the fan controller (they often have more ports than mainboard manufacturers use).
There might be a fan1_div, this is somehow related to how the kernel reads the RPM, I don't know how it works.
temp1_input interfaces can appeare too, if some of the chips have temperature sensors located somewhere. I *think* lm_sensors places the core temperatures it reads from CPU (the coretemp-isa-000X thingies) in one of the hwmon-folders too.
There might be interfaces for different fans in the same hwmon folder, i.e. pwm2_enable, pwm2, fan2_input, etc., all interfaces with the same index belong to the same physical fan connector, and all in the same hwmonN are managed by the same IC on your mainboard.
Warning: These interfaces, if they work, control the fans directly without any kind of security measure. If you shut some essential fan down, it will stay off until you reboot your CPU shuts down.
(If you see something likein0_alarm, in0_input, in0_max, etc. it's a voltage monitoring chip.)
If one of those interfaces can do something, OS-level fan control does work, if none of those folders contain a working pwm interface, fan control seems to be unavailable.
Sometimes there is an option in the BIOS to enable it, and for some BIOSs software-side fan control only works if dynamic fan control is disabled in the BIOS and fan speed is set to a static value - or vice versa.
I don't know what you are using to control fan speed, there are many applications that use these interfaces, i.e. GNOME or KDE power managers, so I'm not sure what is happening:
IF: Windows 7 enables OS-level fan control and sets it the RPM to those you observed and you have nothing that provides fan control in Arch and so fan control stays at BIOS-level, which might also read out a different sensor / the same sensor differently or it might be more conservative in setting fan speeds altogether;
OR: You have something that provides fan control installed in Arch and it reads out a the wrong value supplied by lm_sensors and thus sets a higher fan speed.
Anyway, possible solutions I can think of:
Find out if you have some kind of fan control software and what it does. For example, I use the fancontrol daemon, I can't help you if you use something else.
The wiki mentions how to assign a fan speed to a certain temperature sensors. You might assign it to a different one. For example, there are no sensor chips on the mainboard of my EEE (no temp1 etc.) so I assigned the fan speed to the temperature reported by the BIOS via ACPI (those are in /sys/class/thermal, also no "device" subfolder on EEEs):
FCTEMPS=/sys/class/hwmon/hwmon0/pwm1=/sys/class/thermal/thermal_zone0/temp
You could also change the MINTEMP/MAXTEMP values to one higher than those you actually want to compensate for the effect of lm_sensors reporting temperatures that are too high.
It is currently not possible for a mortal user to change the coretemps lm_sensors reads, see this post, last paragraph.
There is a configuration file, /etc/sensors3.conf, you can change sensor names and adjust offsets here, but only for the monitoring chips and their sensors that are on the mainboard.

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.

[SOLVED] Question about CPU temperature

Hi everybody,
I just want to ask a question about "standard" CPU temperatures because my laptop (a Dell Vostro 3700) is permanently hot with the fans on even when I am not doing anything special.
I have CPU freq scaling active with the conservative governor, and I use Gnome Shell 3.2 with an nVidia using the nouveau driver.
Here are "stable" temperatures while writing this post:
# sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +72.5°C (crit = +103.0°C)
nouveau-pci-0100
Adapter: PCI adapter
temp1: +78.0°C (high = +100.0°C, crit = +110.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +73.0°C (high = +95.0°C, crit = +105.0°C)
Core 2: +73.0°C (high = +95.0°C, crit = +105.0°C)
And this is the output of mpstat
# mpstat -P ALL
Linux 3.1.6-1-ARCH (fm) 01/04/2012 _x86_64_ (4 CPU)

10:16:50 PM 1 1.64 0.21 0.40 0.02 0.00 0.01 0.00 0.00 97.73
10:16:50 PM 2 1.47 0.15 0.67 0.02 0.00 0.06 0.00 0.00 97.64
10:16:50 PM 3 1.36 0.20 0.39 0.02 0.00 0.01 0.00 0.00 98.01
The fan, of course, is full speed (very annoying)
I think that these temperatures are quite high, but I don't know what's really causing all this heating because my laptop is basically idle.
Any suggestion?
Thanks.

Fan spinning is better (less noisy) after specifying the kernel parameters.
Thanks

WIndows can't find a better one than the installed LSI Conformed 1394 Hostcontroller

Read and follow the Bootcamp Installation instructions that you were offered to view when you ran Bootcamp Assistant.
Run Bootcamp Assistant again and select the option to download the Bootcamp Support software. Follow the instructions. Then boot into Windows and install the Windows Support software you downloaded and saved.
