Closer Look:

We are moving a little closer to the completion of our project case and have just a few more items to look at before we can start installing the hardware into our project case. Today, we will be looking at the CPU block and GPU blocks. The CPU block is Danger Den's newest CPU water block, the TDX Uni. It features a universal mounting plate that you can use with both AMD and Intel processors, so there is no worry with purchasing a dedicated block for one manufacturer or the other. In today's market of one-upmanship, one day's champion is the next day's runner up. With performance flipping back and forth between CPU manufacturers so frequently, it is nice to have the option of not having to buy a new block every time you change hardware. For the time being, we will be using this system on a hot running Intel Core2Duo E6700.


The CPU block comes in a non-descript white box with the contents carried on a plain black and white label. Why spend a lot of money on packaging when you can focus on the product. Usually plain wrappers contain a nice surprise inside (at least for women). Let's see if we will find a gem inside this wrapper.



The first items inside the box are the instructions and mounting hardware. In the compartment under is the TDX UNI.



The TDX UNI CPU water block is a universal design that features mounting options for a range of platforms, including AMD socket A/462, 754, 939, 940 and AM2. Along the Intel side of the fence, support is there for socket 478 and LGA775. As with the rest of our sytem, 1/2" fittings are the way to go to maximize the flow through the system. The CPU block ships with a protective adhesive membrane over the contact surface of the block to prevent any damage or scuffing of the CPU contact surface.



After pulling the protective membrane off of the CPU block, I was pleasantly surprised by the finish on the block. The block is machine lapped and polished to above 1200 grit. If you have ever lapped a heatsink, you know what the benefits are from lapping a cooler. A smoother surface can increase surface contact and help cool more efficiently. This type of a finish is something that more manufacturers should strive for. This is another of the small things that sets Danger Den apart from the rest of the crowd.

Closer look:

Included with the block are a set of detailed instructions so that you cannot go wrong with the installation of the CPU block onto the motherboard of choice. You will notice that the instructions are not specific to this product but are for CPU blocks in general. The contents of the package include everything you will need to get this block mounted, from the studs and springs, to the nylon washers and knurled nuts to secure it to the board.





The mounting hardware is included to take care of any platform that this block will be used on. There are springs and spacers for socket 939 processor boards, as well as the correct spring and washer combination for our project. Danger Den even sent us a tube of Artic Silver Ceramique for use on the project.




Closer Look:

There are many options when it comes to cooling your graphics card. You can use just a simple water block for exclusively the graphics processor and use glue or tape on air cooled heatsinks for the memory and power circuits, or you can use a full coverage style block like the one we have chosen. The DD-8800GTS. This block is a full coverage style block that cools not only the GPU, but the memory and power regulation circuits as well. Danger Den states that one should be able to gain a 30 percent overclock by using this particular block. That's a pretty impressive claim I must say. Let's dig a little deeper into this full coverage block to see what it has in store for us.


The box is quite similar to the CPU block box, but bigger and identified as the DD8800GTS. Simple and understated packaging puts the focus on what is inside. Opening the up box shows how the unit is packaged. The block comes sandwiched between two pieces of eggshell foam to prevent any damage.




Instead of the usual acrylic tops that you often see on a full coverage block, this block uses a Delrin (Acetel) cover engraved with the Danger Den logo. The contact surface of the block is the important part here, it's sort of where the rubber meets the road. The 8800GTS covers all of the heat generating components on all of the reference design (EVGA, BFG, XFX, PNY, etc.) 8800GTS video cards. The components that are covered include the GPU chip, the memory chips, the voltage regulators and I/O chip.



The contact surface of the water block is hand lapped to create a flat smooth mating surface to promote better cooling of the GPU. The areas around the GPU contact surface are not machined as well, but they are not in contact with any of the heat producing components.

Closer Look:

Most air cooling solutions (including stock) for the 8800 series video cards take up at least two expansion slots on the board's surface. This becomes a problem when it comes time to install any expansion cards. You may be out of luck when it comes to using air to cool the components, I know I was. The thin design of the DD-8800GTS makes the use of these expansion slots possible again. This fact alone makes the choice to go water cooling worth the effort.





Because we will be using two video cards in our setup, a short 1/2 inch fitting was supplied to manage the space between the two video cards. Two of the standard length fittings will not allow the cards into the slots to run SLI. You can clearly see the difference in the size of the fitting when a comparison is being made



The items that come with the 8800GTS block include all of the mounting hardware, as well as a set of instructions. A tube of Artic Silver Ceramique is included, as well as a thermal pad that must be used for the power regulation circuits.



As you can see, the size difference between the water and air cooling sinks is huge. Going from a dual slot cooling to single slot is going to open up the slots lost to air cooling.




Now that we have seen all of the components that we have chosen to use for our water cooling buildup, we can move on to the installation, final build up, and testing of our components pre and post water cooling. This way, we can validate the performance numbers given to us by Danger Den. I can't wait. Please stay tuned for the final installment of this series here at
