I put the system on load and I noticed their value hardly changes. To my surprise, I ran a benchmark for 3 minutes and none of temp* values changed during execution. The highest reported temperature is always 48C.
I was expecting that the internal temperature would have "sensor = thermal diode" or "sensor = core" as a keyword. I thought "sensor=thermistor" means the corresponding sensor is on the motherboard and not the internal die-sensor.
Also, I noticed something that even though I installed and inserted the driver for f71882fg, when I run "sensor-detect", it still says that "Note: there is no driver for Fintek F71869FG SUper IO Sensors yet". I thought the driver name for F71869FG chip is f71882fg (as per http://lm-sensors.org/wiki/Devices). I installed this driver from here: http://khali.linux-fr.org/devel/lm-sensors/drivers/f71882fg/ .
I am not worried about the fan-rpm because I intentionally replaced the fan with a custom heat sink. I mentioned that just so that you ignore those lines;-).
Thanks,
Kapil

You might be able to find a correlation by putting the system under load
and observing temperature rises.
If nothing turns it can't measure rpm ...
