isn't that a C/W of 0.313?
C/W is dT/W or (Die temp - water temp)/watts (look at pH's graph)
(52.5 - 44.7)/100 = 0.078 deg C per watt

C/W values are proportional to the area of contact between die and waterblock/HSF. Therefore C/W values can not be directly compared from one thermal die simulator to another unless they have the exact same surface area.
