w83781d Sensor Labeling Documentation (Examined/Solved - lm_sensors 2.4.5 linux-2.2.14)
|Reported by:||contact||Owned by:||somebody|
Motherboard is EP-MVP3G-M, cpu AMD K6-2 500mhz. Problem is either that I'm lame and haven't read enough of the docs, or it simply isn't there. I can't find any labeling as to what /proc files temp1, temp2, temp3 are actually measuring. Output from sensors command essentially lists the name of the /proc temperature file, along with somewhat variable & reasonable temperature values (so I know they're measuring something). doc/chips/w83781d correctly states that there is 3 temp sensors. Further down it indicates I should check lm78 docs for /proc entries. Unfortunately it appears lm78 only uses one temperature sensor. The default sensors.conf isn't much help either, which is to be expected since the sensors command simply lists the file name rather than a label. From the readings I get, temp3 appears to be cpu temperature. temp1 and temp2 usually remain equal or within a single degree C of each other. Thanks for any insight you might have on this. -Donald Thompson
--- It all depends on the wiring of your mainboard. The usual convention is to have temp1 connected to the mainboard, and temp2 or temp3 to the processor, but it is not a hard rule. Mainboard manufacturers can do it any way they want, and you can't find out except by trying or asking them. That's why there is a sensors.conf file - because there is simply no way for us to know.
