Danger Den MC-TDX Waterblock
 

Danger Den redesigned the TDX to improve its performance on multiple-core CPUs. This new version, dubbed the MC-TDX, features 240 pins above the CPU core area to help dissipate heat. The rest of the design is classic TDX, with its offset outlet barb, acrylic top and simple mounting hardware.
