Looking at the Team Brood item, it is clearly an air cooled heatsink. It's difficult to design heat sinks which do not damage the motor label or whos thermal conductivity is not spoiled by the label. As a result the makers claim 30F improvement.
TCS liquid cooling lowers motor temp 50F and forms a permanent installation into the car without obscuring the motor label or affecting normal motor installation
Additionally air fans draw 1.3watts of power per fan, whereas a TCS only uses 0.4w.
A TCS therfore gives considerably more cooling than anything else available for less power usage.
