Thinking about water cooling you computer? Water cooling is not as wacky as it sounded five years ago, and today top companies like Danger Den are making performance-minded kits that will make "pro" cooling a breeze.
Danger Den is a company that has become a mainstay when it comes to water cooling computers. Anyone who has used H2O to cool a computer has very likely run across the Danger Den name. Since 2000, Danger Den has put out some of the best water cooling products on the planet. Not only has Danger Den put out cutting edge products by consistently redefining water block design, their water blocks have always pushed the limits of the water cooling performance envelope.

Danger Den has enjoyed years of success by creating a high quality product and standing behind it. The world of water cooling is a brutally competitive industry in which you either remain competitive or fall be the wayside. Over the last 5 – 7 years, only a few names have remained consistent in the water cooling world and Danger Den is one of those names.
Today, we have a Danger Den water cooling kit for the Athlon 64 that features the TDX and TDX Silver water block. Here is what Danger Den has to say about the TDX water block:
Based off the popular RBX waterblock design, the TDX takes advantage of all the features and performance levels that made the RBX one of the best performing waterblocks on the market, while simplifying and improving the user interface. Key features of the TDX include: Incorporates the use of two HF fittings vs. three on the RBX, while maintaining the high level of performance achieved with the RBX. With the elimination of the third fitting there is no longer a need for the "Y" adapter to plumb the TDX in your system. Reduces the amount of hose clamps and tubing required to plumb the TDX into your system.
Danger Den has some of the finest packing in the business. Each component in the Danger Den kit comes individually packaged in separate white boxes or carefully wrapped in bubble wrap. The components are then carefully packed in a large shipping box with additional padding (packing foam / peanuts ). Included in the kit: One TDX copper water block. One Maze4 chipset block. One 12v Laing Thermotech water pump. 6ft. ½” Tygon tubing. One Thermochill HE120.1 radiator. One 12v Sunon 120mm Fan. One dual floppy bay reservoir. Installation manual. Miscellaneous installation hardware. 4oz bottle of Zerex coolant.

The TDX, though it shares a few features with previous Danger Den blocks, is radically different from anything we have seen from Danger Den. The features that the TDX shares with older Danger Den blocks are the two piece design and Lucite top, but the similarities pretty much stop there.
The TDX is much smaller than previous blocks and sports a unique teardrop shape. The base of the TDX has a small area of offset water channels milled into the base directly beneath the inlet barb. Sandwiched between the Lucite top and the base of the block right below the inlet barb and above the water channels is an interchangeable “accelerator nozzle” that changes the flow characteristics of the incoming water. The preinstalled “slotted” accelerator nozzle was used throughout our tests (more on this later.
The TDX weighs in at a rather light 140 grams. This is less than half the weight of any of the blocks we tested against and much lighter than its predecessor, the Maze 4. Looking at the footprint of the TDX versus the Maze 4 in these side-by-side pictures the size difference is very noticeable.
The chipset waterblock used with this kit is the Maze 4 chipset block. There are several varieties of this block available to fit just about any motherboard you might have. For our review we are using the chipset block that is made for motherboards that use holes around the chipset to mount a cooler. The Maze 4 chipset cooler will work on motherboards that have center-to-center hole distances ranging form 2.10" - 2.43".
Danger Den also offers other chipset blocks and hold down hardware for motherboards that use the hook style hold down common on Intel based boards.
