félreértettél…amikor a cpu venti KIKAPCSOLÁSRÓL volt szó, nem a gép kikapcsolásáról 🙂 Ha megy a gépem és nem használom, nem kapcsol ki a venti, habár a cpu hömérséklet már nem indokolná. Ha bekapcsolom, nem kapcsol be addig amíg el nem éri azt a 47C-t. Ez lenne a dinamikus cpu freq szabályozás lényege, hiszen így tudok megspórolni energiát és zajt…

pomm progik # pwmconfig
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

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.

We can start with probing for (PCI) I2C or SMBus adapters.
Do you want to probe now? (YES/no): yes
Probing for PCI bus adapters…
Use driver `i2c-viapro’ for device 0000:00:11.0: VIA Technologies VT8237 South Bridge

We will now try to load each adapter module in turn.
Module `i2c-viapro’ already loaded.
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.

To continue, we need module `i2c-dev’ to be loaded.
Do you want to load `i2c-dev’ now? (YES/no): yes
Module loaded successfully.

We are now going to do the I2C/SMBus adapter probings. Some chips may
be double detected; we choose the one with the highest confidence
value in that case.
If you found that the adapter hung after probing a certain address,
you can specify that address to remain unprobed.

Next adapter: SMBus Via Pro adapter at 0400 (i2c-0)
Do you want to scan it? (YES/no/selectively): yes
Client found at address 0x30
Client found at address 0x31
Client found at address 0x50
Probing for `Analog Devices ADM1033’…                    No
Probing for `Analog Devices ADM1034’…                    No
Probing for `SPD EEPROM’…                                Success!
    (confidence 8, driver `eeprom’)
Probing for `EDID EEPROM’…                                No
Probing for `Maxim MAX6900’…                              No
Client found at address 0x51
Probing for `Analog Devices ADM1033’…                    No
Probing for `Analog Devices ADM1034’…                    No
Probing for `SPD EEPROM’…                                Success!
    (confidence 8, driver `eeprom’)

Some chips are also 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 `National Semiconductor LM78-J’ 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
Probing for `Winbond W83627HF’ at 0x290…                  No
Probing for `Silicon Integrated Systems SIS5595’…        No
Probing for `VIA VT82C686 Integrated Sensors’…            No
Probing for `VIA VT8231 Integrated Sensors’…              No
Probing for `IPMI BMC KCS’ at 0xca0…                      No
Probing for `IPMI BMC SMIC’ at 0xca8…                    No

Some Super I/O chips may also contain 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):
Probing for Super-I/O at 0x2e/0x2f
Trying family `ITE’…                                      No
Trying family `National Semiconductor’…                  No
Trying family `SMSC’…                                    No
Trying family `VIA/Winbond/Fintek’…                      No
Probing for Super-I/O at 0x4e/0x4f
Trying family `ITE’…                                      Yes
Found unknown chip with ID 0x8510
Trying family `National Semiconductor’…                  Yes
Found unknown chip with ID 0x8510
Trying family `SMSC’…                                    Yes
Found unknown chip with ID 0x8510
Trying family `VIA/Winbond/Fintek’…                      Yes
Found `Winbond W83687THF Super IO Sensors’
    (but not activated)

Some CPUs or memory controllers may also contain embedded sensors.
Do you want to scan for them? (YES/no):
AMD K8 thermal sensors…                                  Success!
    (driver `k8temp’)
Intel Core family thermal sensor…                        No
Intel AMB FB-DIMM thermal sensor…                        No

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

Driver `eeprom’ (should be inserted):
  Detects correctly:
  * Bus `SMBus Via Pro adapter at 0400′
    Busdriver `i2c-viapro’, I2C address 0x50
    Chip `SPD EEPROM’ (confidence: 8)
  * Bus `SMBus Via Pro adapter at 0400′
    Busdriver `i2c-viapro’, I2C address 0x51
    Chip `SPD EEPROM’ (confidence: 8)

  EEPROMs are *NOT* sensors! They are data storage chips commonly
  found on memory modules (SPD), in monitors (EDID), or in some
  laptops, for example.

Driver `k8temp’ (should be inserted):
  Detects correctly:
  * Chip `AMD K8 thermal sensors’ (confidence: 9)

I will now generate the commands needed to load the required modules.
Just press ENTER to continue:

If you want to load the modules at startup, generate a config file
below and make sure lm_sensors gets started at boot time; e.g
$ rc-update add lm_sensors default
To make the sensors modules behave correctly, add these lines to
/etc/modules.d/lm_sensors and run modules-update:

#—-cut here—-
# I2C module options
alias char-major-89 i2c-dev
#—-cut here—-

If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones! You really
should try these commands right now to make sure everything is
working properly. Monitoring programs won’t work until the needed
modules are loaded.

To load everything that is needed, execute the commands below…

#—-cut here—-
# I2C adapter drivers
modprobe i2c-viapro
# Chip drivers
modprobe eeprom
modprobe k8temp
# sleep 2 # optional
/usr/bin/sensors -s # recommended
#—-end cut here—-

Do you want to overwrite /etc/conf.d/lm_sensors? Enter s to specify other file name?
  (yes/NO/s): yes
Done.

nem sajna, ezen már pár hete túl vagyok…más 5let?

pomm progik #ls /sys/bus/i2c/devices/
0-0050  0-0051
pomm progik # ls /sys/bus/i2c/devices/0-0051/
bus  driver  eeprom  name  power  subsystem  uevent
pomm progik # ls /sys/bus/i2c/devices/0-0050/
bus  driver  eeprom  name  power  subsystem  uevent
pomm progik #

Erről van szó.
