I've got a Jetway S755MAX (SIS755 chipset) with an AMD 64 3000+. The
board uses an IT8705F and I've got the it87 driver loaded. LM_Sensors
version 2.8.4 (MDK10.0). Everything works fine except I can't get the
CPU temp working. Of the 3 temp sensors on the chip the only thing I've
figured out is that temp2 is the MB temp. I've located the thermistor
for this and everything is fine with it. I have no clue what temp1 is
for. It stays at 70C most of the time. the only way I can get it to
change is to run a a few sessions of glxgears. It will then go up to
72C max. Now temp3 is wild. It flucuates from 13C to about 54C and
anyplace in between. I've gone as far to to disconnect my cpu fan to try
and see a rise on these sensors, but I see none. Temp1 stayed at 70C,
and temp3 acted the same and actually went from 54C to 13C once during
this test. For the record, the bios cpu temps are stable around 41C, and
using Smartguardian in win works fine. I've contacted Jetway, but I
don't think they understand english very well, as I can't get a an
answer as to which sensor is for the CPU. Anyway, with the sensors set
to anything but thermistor, I get an invalid with sensirs output. Here's
what I'm getting now using no temp computes.

Any advice, even forget it would be helpful. I've messed with this for
months. If you need more info let me know.
Thanks, Wes
