Thermalright XWB-01 Waterblock Review
 

The XWB-01 is a rather small waterblock and measuring no larger than 2.5 inches on its longest side. In terms of size it is comparable to the Danger Den TDX. The block is plumbed for 1/2" ID hoses in a 2 barb configuration with the center inlet directly over the processor core.
