ok i did it twice once with the adt7473 kernel module loaded and got 2 
different readouts.

first, this is with the 7473 module loaded:

--- GKrellM 2.3.2 ---
hddtemp_daemon_read (once a minute):
        |/dev/sda|WDC WD7502ABYS-02A6B0|34|C||/dev/sdb|WDC WD7502ABYS-02A6B0|

nvidia-settings gpus = 2

then this is without the module loaded:

fans 1-4 are for the motherboard and work fine. fan5 duplicates fan4.
none of the it87 inX voltages are correct except in1 which is the ram voltage.
all the others are useless. eg: i read somewhere in3 was supposed to be the 5v 
line. it reads 2.94v

but anyway i don't see anything with or without the 7473 loaded to help.
