When I first inspected at the TDX, I was immediately impressed with the changes that had been made from the RBX design and with the machining quality and construction. I am not a huge fan of three-barb waterblocks (too much hassle to route tubing without putting torque on block), and a return to the traditional two-barb design is welcome. I found the base of the RBX to be a bit narrow for mounting reproducibly well in previous testing, and the TDX has addressed this by widening the base
