Danger Den TDX vs Cool Cases CF1 v2

Cooling/Water Cooling by KeithSuppe @ 2004-06-28

A new revision of the Cool-Cases CF1 is put up against Danger Den?s latest high performance water block, the TDX. Which one will keep an Athlon 64 the coolest, read on to find out.

Danger Den TDX

Next up is Danger Den's TDX water block. The TDX incorporates many of the features found in their RBX, and a few new modifications as well.

First off the block is diminutive, just barely covering CPU's it's designed for. This allows the water block maker to experiment with more costly mediums (metals), such as silver. Danger Den has taken advantage of this offering the S-TDX, which is the TDX machined from 99.9% silver. The TDX design is based on isolation cups machined into the copper (or silver) base plate, comprising the primary impingement zone. These cups are staggered along channels each perpetuating a bi-lateral return flow. Water rapidly exits the impingement area flowing into the block's main chamber, where it's forced through the outlet.

In the TDX, Danger Den has chosen to re-introduce its "heat voids" and accelerator-nozzle technology. This allows the end-user to choose among five nozzles each producing a unique inlet water-stream. Nozzle-1 for example, features a simple rectangular type inlet with tiny ridges along the opening, it's conducive to low flow systems. Nozzle-5 offers a multi-stream inlet, better suited to higher pressure pumps.

The next photo exemplifies Danger Den's excellent CNC machining defining the isolation cups and ridges in the impingement zone. Multiple water streams enter the individual cups, creating turbulence improving heat absorption. The channels along which the cups are staggered, this propagates a bilateral flow as heated water exits to the block's main chamber. Once the water enters the outer chamber, the shape of the TDX directs the flow downward (depending on Socket orientation) to the outlet.

The same view with accelerator nozzle-1 replaced (nozzle-1 will be used throughout this review);

As seen in the next photo, Danger Den's base plate thickness is deceptive from the angle photographed. While it may seem as if it's a full centimeter, the next photo will indicate the machining depth.

Thickness between maximum base depth, (bottom of the isolation cups) and CPU is approximately 2mm. This is just about equal to the thickness of the CF-1's base plate. Danger Den used much more copper in their TDX design, as the chamber walls are a full cm in height.

For this review I used accelerator nozzle-1 which was included with the TDX.
