Question on fan minimum/divider values (Examined/Solved - Sensors 2.5.5 Linux 2.4.2-SMP)
|Reported by:||contact||Owned by:||somebody|
I'm a little puzzled about the output of Sensors v1.3 on my SMP Linux
Below is the output I get. This is on a Giga-Byte 6BXDU motherboard. The
devices I have to read are 2 P3/850 CPUs and the motherboard itself. Each
of these 3 devices has a temperature sensor and a variable-speed fan
attached to it. (Regarding the m/b, I'm referring to a fan other than that in
the power supply.)
the m/b conditions.
But check out those Fan#3 min and divider values. In this case it looks
like Fan#3 is the "odd man out". It doesn't seem reasonable to me that
these values would differ between the 2 processors.
In case it's relevant, this is a fragment of lsmod output:
w83781d 17120 0 (unused)
sensors 6576 0 [w83781d]
i2c-isa 1232 0 (unused)
i2c-core 13696 0 [w83781d sensors i2c-isa]
LM_Sensors v2.5.5 (Sensors v1.3) is working well in my environment. I'm just
curious about those minimum/divider values.
Any thoughts on this?

fan3: 4963 RPM (min = 750 RPM, div = 8)
temp1: +84.2F (limit = +140F, hysteresis = +122F) sensor = thermistor
temp2: +95.9F (limit = +140F, hysteresis = +122F) sensor = thermistor
temp3: +92.3F (limit = +140F, hysteresis = +122F) sensor = thermistor
--- A fan div of 8 results in 750 minimum.
The fan div can be set by the driver via /etc/sensors.conf
and 'sensors -s' or via /proc. See doc/fan-divisors for more info.
To be sure which fan is connected to which sensor stick a pencil
in the fan and run 'sensors'.
