It's easy to see there are some completely bogus values in there. I
Other than the -12V, I see no bogus values, other than the stopped fans.
(Maybe the V5SB is a bit off, but it can be your power supply.)

don't know about the fan speed - the bios correctly reports it, but it
doesn't show here (and I'm _really_ interested in seeing a fan that does
337500 rpm as a minimum...). Whatever, I found the two measured
Maybe you need to increase the 'div' on the fans to get a reading.
Try something like:

echo 32 > /sys/bus/i2c/devices/0-0290/fan1_div
echo 32 > /sys/bus/i2c/devices/0-0290/fan2_div

to read out the fan rotation when they are running at low speeds.

temperatures to be correct. temp1 is motherboard temp, temp2 is cpu
temp. fan2 is cpu fan here, and I can throttle it to as low as 120,
which stabilizes cpu temperature at about 32°C during normal typing work
(so, idle most of the time) on a 3200+ using powernowd. Probably I could
even switch it off, but air flow in my box isn't too good (and frankly,
I don't care - on 120, the fan isn't audible anyway.)
I wonder what happens to the CPU temperature when you run
'while true; do true:done' for ten minutes, or if you try render something with povray. Static fan settings can be dangerous, when set too low. Luckily the AMD64 processors all have thermal protection.
