here's the review of the whole kit that comes w/ the waterblock.
LINKY!!! of course, that company doesn't produce anything themselves but rather they gather good parts from other companies and provide it to the consumer in a package. we've seen many rip offs in our time, just think of all the heatsinks w/ very similar designs, one i can remember is the ThermoEngine design, Scyth's Kamakaze design is VERY similar to an Alpha heatsink. look at what happened wehn CoolerMaster first came out w/ the heatpipe design, now many many companies utilize that design and idea. other companies will continue to use other's ideas and "remanufacture" and "reverse engineer" components. i feel that Cathar should still be entitled to some royalties b/c i know the company is going to bank off of this. but here's the review. apparently it performs well.
