Tigermain has posted a review of this over at moddin.net. One of the best things about this review, besides further proving it is a POS, he has taken time to pull it apart, including the pump assembly. Plenty of pics.
It appears the one he had was using a 60mm fan with the fins "cut off" to power the pump, essentially a mag drive pump.
It appears that the water is sucked up from the cooling chamber into the center of the impeller and expelled out of a side exit. So no cold water straight on to the die.
Anyway, here is the link.
