They are:
a) decieving the public by continuing to ship hollow-core review units rather than solid core units, despite their own test data showing that they made this change back in December of 2000. They also include a better fan in the review units.
b) They now claim that the solid core performs better, but that isn't the case
c) HardOCP testing is crap. Frostytech, while better, did not test iwth the Delta 38CFM fan. However, when they switched from the TT fan that comes with the retail to the YS tech review unit fan, the Difference between hollow core and solid core grew from .6C to 2.1C, indicating that the solid-core may not scale as well to a more powerful fan.
d) All of which begs the question, if Thermosonic was convinced of the solid-core's performance back in December, why are all review units supplied by Thermosonic Hollow-Core?
