-On some motherboards with NCT6776F, temperature readings for CPUTIN and AUXTIN

+On various ASUS boards, it appears that CPUTIN is not really connected to
+anything and floats, or that it is connected to some non-standard temperature

 increases.

-On an ASUS P8H67V board, the observed relationship between measured and real
-temperatures was approximately
-       T(cpu,real) = 80 - (T(cpu,measured) / 2)
-       T(aux,real) = T(aux,measured) - 30000
-if the thermal sensor type was set to "thermistor(4)".
-
-The reported value for CPUTIN sometimes jumps significantly, up to 10 degrees C
-between measurements. Changing the sensor types on that board to diode(1) or
-thermal diode (3) did not help.
-
-The problem with AUXTIN can possibly be addressed by setting temp3_offset to
--30000. It is currently unknown, however, if the AUXTIN sensor is actually
-connected to anything. The CPUTIN sensor is obviously connected to something,
-but how the reported temperature relates to the real world is unknown. 
+CPUTIN should therefore be be ignored on ASUS boards. The CPU temperature
+on ASUS boards is reported from PECI 0.
