Computer running 10degrees hotter? [Solved]

Postby greendave8 » Sun Sep 29, 2013 10:38

Hi All,

Since I updated a couple of weeks ago, my computer is definitely running about 10 degrees C hotter than it used to. This is since I upgraded the kernel to 3.11... I thought perhaps the next update may sort it out, but last nights has made no difference. And yes, thye machine is dust free, and water cooled. Running KDE 4.11 and kernel 3.11
Hardware is an i7 multicore processer and Asus P8P67 board with 16Gb of RAM....

Anyone else notice this, is this kernel harder on cpu etc?

Just wondering... :?: :bom:

Can you check the origin maybe?
I assume, it's not your core-i7, more than, I assume it's your graphic adapter. Do you have an nvidia or which one?
Can you run
Code: Select all
sensors-detect

then save the values when this program exits and then install some programs (gkrellm or nvidia temperature messurement tools). This will give you a hint.
When I change my grafic mode settings in BIOS from 'integrated' to 'switchable', means use nvidia instead of build-in Intel, then my power consumption rises more than double. At this moment, I haven't yet installed the best nvidia driver for my GForce GT630M, which is an Optimus card and should be supported by linux with 'bumblebee', if you install it correctly.
As I said, this happens to me. So I set my BIOS to 'integrated' graphic mode. My power consumption with Core-i5 and the mentioned 'integrated' Intel graphic adapter is between 19 watts/h normal and 28/30 watts/h when using kaffeine with an external usb-dvb-t stick.
My cpu temperature does not really exeed 50, 55 centigrades when normal use, and in more extremely use, e.g. ProjectX demux, I've reached 66 centigrades, then cooled down again to the normal value.

Hi Linuxfluesterer,

Code: Select all
dave-sabayon christine # sensors-detect
# sensors-detect revision 6170 (2013-05-20 21:25:22 +0200)
# Board: ASUSTeK Computer INC. P8P67 PRO

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): y
Silicon Integrated Systems SIS5595...                       No
VIA VT82C686 Integrated Sensors...                          No
VIA VT8231 Integrated Sensors...                            No
AMD K8 thermal sensors...                                   No
AMD Family 10h thermal sensors...                           No
AMD Family 11h thermal sensors...                           No
AMD Family 12h and 14h thermal sensors...                   No
AMD Family 15h thermal sensors...                           No
AMD Family 15h power sensors...                             No
AMD Family 16h power sensors...                             No
Intel digital thermal sensor...                             Success!
    (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): y
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'...               No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Nuvoton/Fintek'...               Yes
Found `Nuvoton NCT5577D/NCT6776F Super IO Sensors'          Success!
    (address 0x290, driver `nct6775')
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor/ITE'...               No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Nuvoton/Fintek'...               No
Trying family `ITE'...                                      No

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): y
Probing for `IPMI BMC KCS' at 0xca0...                      No
Probing for `IPMI BMC SMIC' at 0xca8...                     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): y
Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM79' 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): y
Using driver `i2c-i801' for device 0000:00:1f.3: Intel Cougar Point (PCH)
Module i2c-dev loaded successfully.

Next adapter: NVIDIA i2c adapter 0 at 1:00.0 (i2c-0)
Do you want to scan it? (yes/NO/selectively): y

Next adapter: NVIDIA i2c adapter 6 at 1:00.0 (i2c-1)
Do you want to scan it? (yes/NO/selectively): y

Next adapter: NVIDIA i2c adapter 8 at 1:00.0 (i2c-2)
Do you want to scan it? (yes/NO/selectively): y

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

Driver `coretemp':
  * Chip `Intel digital thermal sensor' (confidence: 9)

Driver `nct6775':
  * ISA bus, address 0x290
    Chip `Nuvoton NCT5577D/NCT6776F Super IO Sensors' (confidence: 9)


Do you want to overwrite /etc/conf.d/lm_sensors? Enter s to specify other file name?
  (yes/NO/s): y
Done.
You should now start the lm_sensors service to load the required
kernel modules.

Unloading i2c-dev... OK


Yes I am running an nVidia card GTS450, starngely the machine is idling nicely then starts to ramp up the fan.... for no reason. It gets to 70C or more, then cools down. I have checked htop, and the last thing I seen running was "plugin-container" using 43% of cpu.... I dont know what that is, let alone use it?

Thanks for the help, and you fixed gkrellm for me last week. Thats where I am gettiong the temps from...

Do you run 'Firefox'? Then close it for a try. Then check the temperatures and your cpu % use again, pls.
I have read an article, that this 'plugin container' is part of 'Firefox'.
If you confirm to use firefox, you can disable 'plugin-container'. In Firefox URL line you'll type:
Code: Select all
about:config

Then you must find the entry (with filters):
Code: Select all
dom.ipc.plugins.enabled
and set the value from 'true' to 'false'

Then next step is to find:
Code: Select all
dom.ipc.plugins.timeoutSecs
and set the value to -1.
Restart Firefox and see what happens. Let me know, pls., because I don't use Firefox, I use Chromium.

Yes, I use Firefox, and I too discovered that this may be the problem. BUT... I didnt know how to fix it, so I will try your method above. Many thanks again

linuxfluesterer,

Your advice seems to have worked... CPU running around an average of 42C now, with much fewer "ramp-ups"...
I marked topic as solved.... Thanks again
