A few weeks ago I build 2 nasses (see previous posts). No it’s time to do some tweaking and do some info-gathering from these machines. In this case. How are the fans, cpu’s etc doing. ie lm-sensors.
Installing lm-sensors is straight-forward: sudo apt-get install lm-sensors.
Initial setup is also straight-forward, just run sudo sensors-detect:
Summary of the output:
Intel Atom thermal sensor... Success! (driver `coretemp') Trying family `ITE'... Yes Found `ITE IT8720F Super IO Sensors' Success! (address 0x290, driver `it87') Now follows a summary of the probes I have just done. Just press ENTER to continue: Driver `it87': * ISA bus, address 0x290 Chip `ITE IT8720F Super IO Sensors' (confidence: 9) Driver `coretemp': * Chip `Intel Atom thermal sensor' (confidence: 9) To load everything that is needed, add this to /etc/modules: #----cut here---- # Chip drivers coretemp it87 #----cut here---- If you have some drivers built into your kernel, the list above will contain too many modules. Skip the appropriate ones! Do you want to add these lines automatically to /etc/modules? (yes/NO)
Now everything is setup. With the command sensors cpu and fan info will be shown. For my ga-d525tud mainboard some values are utter crap. So I found somewhere on the internet an updated configfile for my mainboard (lm-sensors-ga-d525tud). Copy this file to /etc/sensors.d. Now only usefull parameters are shown. In my case:

NOTE: while writing this on my macbook, I discovered the tilde sign (˜) is missing from an mac keypad. Luckily google was again my friend: The ˜ will show up with key combination ALT-n.
