 # SiS5595 temperature calculation

+# The driver currently includes a calculation due to the wide
 # variation in thermistor types on SiS5595 motherboards.
+# The driver currently has a calculation of t = (.83x + 52.12).
+# One user reports the correct formula of t = (.345x - 12).
+# So you want to put a compute line in sensors.conf that has
+# the inverse of the driver formula, and put your formula on top of it.
+# The inverse of the driver formula is x = (1.20t - 62.77)
+# So the final formula is newt = (.345(1.20t - 62.77)) - 12).
+# Put this in the sensors.conf file as
+# compute temp ((.345 * ((1.20 * @) - 62.77)) - 12), ...
+# where ... is the inverse function I leave to you.
