Recommended apps to monitor temperatures?

littlebigman · Post by **littlebigman** » 2009/12/30 12:32:36

Hello

I'm running CentOS 5.4 on an Atom-based motherboard with a quiet, low-power PSU. As the only fan left is a 40mm fan to cool the Intel 945GC chip, I'd like to run a utility to monitor the 945GC and HD temperatures. Ideally, it should be able to run the 945GC fan faster when it's needed.

What application would you recommend to do this?

Thank you.

It seems like the most-used application is "lm-sensors", but it fails:

[code]
# yum install lm_sensors

# sensors-detect
[...]
Now follows a summary of the probes I have just done.
Just press ENTER to continue:

Driver `it87' (should be inserted):
Detects correctly:
* ISA bus, address 0x290
Chip `ITE IT8718F Super IO Sensors' (confidence: 9)

Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no): YES
Starting lm_sensors: No sensors found!
[b]Make sure you loaded all the kernel drivers you need.[/b]
Try sensors-detect to find out which these are.

[/code]

I suggest you try the [url=http://elrepo.org/tiki/kmod-it87]kmod-it87[/url] package from [url=http://elrepo.org]ELRepo[/url].

The current kmod-it87 does not detect Intel thermal sensor on the Atom 330 dual core, but I think it does work for earlier Atoms.

[code]# dmidecode processor|grep Atom
Family: Atom
Version: Intel(R) Atom(TM) CPU 330 @ 1.60GHz

# rpm -q kmod-it87 lm_sensors
kmod-it87-1.1-2.el5.elrepo
lm_sensors-2.10.8-2.el5.elrepo
lm_sensors-2.10.8-2.el5.elrepo

# sensors-detect
...
Some south bridges, CPUs or memory controllers may also contain
embedded sensors. Do you want to scan for them? (YES/no):
Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No
AMD K8 thermal sensors... No
AMD K10 thermal sensors... No
Intel Core family thermal sensor... No
Intel AMB FB-DIMM thermal sensor... No
VIA C7 thermal and voltage sensors... No
...[/code]
Using the native lm_sensors:

[code]# rpm -q lm_sensors
lm_sensors-2.10.7-4.el5
lm_sensors-2.10.7-4.el5

Thanks guys for the tip but... no go :-/

[code]
# rpm -Uvh ./lm_sensors-2.10.8-2.el5.elrepo.i386.rpm
# rpm -Uvh ./kmod-it87-1.1-2.el5.elrepo.i686.rpm

# sensors-detect

If you know of an other application that can monitor the CPU+chipsets on an Atom CPU 230 @-based motherboard, I'm interested.

Thank you.

I had to shutdown the 'puter to put the case back on... and "sensors" now works:

[code]
# sensors
it8718-isa-0290
Adapter: ISA adapter
in0: +1.12 V (min = +0.00 V, max = +4.08 V)
in1: +1.82 V (min = +0.00 V, max = +4.08 V)
in2: +3.31 V (min = +0.00 V, max = +4.08 V)
in3: +4.08 V (min = +0.00 V, max = +4.08 V) ALARM
in4: +3.09 V (min = +0.00 V, max = +4.08 V)
in5: +0.06 V (min = +0.00 V, max = +4.08 V)
in6: +0.03 V (min = +0.00 V, max = +4.08 V)
in7: +4.08 V (min = +0.00 V, max = +4.08 V) ALARM
in8: +3.06 V
fan1: 3426 RPM (min = 0 RPM)
fan2: 0 RPM (min = 0 RPM)
fan3: 0 RPM (min = 0 RPM)
temp1: -55??C (low = +127??C, high = +127??C) sensor = thermistor
temp2: -2??C (low = +127??C, high = +127??C) sensor = thermistor
temp3: +33??C (low = +127??C, high = +127??C) sensor = diode
vid: +2.050 V
[/code]

Problem solved. Thanks guys.
