A Closer Look

The Danger Den MC-TDX is the updated version of the classic TDX CPU waterblock. For this reason, its appearance is almost completely identical to its predecessor. The bottom of the block is made of cast 110 copper that is machined to allow assembly, while the top is 1/4" thick Lucite (Acrylic). There is an optional brass top for those that prefer it.


The main difference between the new MC-TDX and the old TDX is that the new MC-TDX has 240 pins over the CPU core area. The MC-TDX was designed especially for quad core processors that carry much more heat than the dual cores when they are pushed and that is where the MC-TDX excels. On the inlet side of the block one of the chrome plated fittings is located directly over the center of the pins, while the water flows across the block and leaves through the outlet barb. A black rubber O-ring seals the top and prevents leaks.


The bottom of the block comes protected with some heavy tape. When removed, the base of the block did not have any residue left on it. The base is machine lapped and polished, although it is not as shiny as one might expect.


The base of the MC-TDX is smooth, but there were a few high points on the surface as shown with the razor blade test. However, these high points were toward the outside of the block, and the inside area seemed relatively flat. When placed next to the box the MC-TDX came in, the finish is not very reflective, but reflective distortions were not noticed.
