I really have no complaints about this kit. Very complete but also very difficult to put into service for the first time. They really were not stingy with 2m tubes that plenty. The pump and radiator are clearly oversized allowing scalability of the kit. I associated with the waterblock for ATI Radeon HD 7970 CG of the same brand and have very good results. I had some difficulties to turn the air bubbles from the circuit but once it's done, it's just happiness.
