Danger Den TDX

Waterblock Test – Joe

SUMMARY: Good choice for CPU cooling, but needs a good waterpump to perform.

Jeremy over at Danger Den was nice enough to send their TDX waterblock to test.

Danger Den’s TDX features

• Chrome-plated barb connectors for ½” ID tubing
• Lucite Top
• User changeable “accelerator plates”

This waterblock is designed around “accelerator plates” which serve to accelerate the waterflow to a high pressure stream:

In addition, there are 6 channels machined into the base to increase turbulence:

I also noted that there is no way the accelerator plate can be misaligned – the plate features two “bumps” so that it can only fit such that the slit fits over the channels.

Danger Den’s blocks carry a warning label on it stating “Warranty Void if Removed”. This does not mean that if the consumer who buys the block were opens it up, the warranty is voided. Danger Den informed me that “…the “Void” sticker is used to guarantee a sealed water block (leak tested) to the customer. We still have 100% manufacturer defect warrantee even if the sticker is removed.” See their FAQ HERE.

The base

is well finished and polished.

Also available are additional “accelerator plates” for lower or higher pressure, and a blank so that users can try out their own design.

The TDX was tested using the CPU Die Simulator and Waterblock Test Rig. I used the #4 accelerator plate for this test.

Test Results indicate that the TDX’s pressure drop (or head loss) across the waterblock is moderate; flow resistance such as this means that TDX should function very well without using a very large waterpump, although anything less than 300 gph might compromise results, depending upon how restrictive other components are in system.

I found that reducing flow to 0.5 gpm resulted in a performance decrease of about 1.7ºC and increasing flow to 1.5 gpm resulted in a gain of about 0.9ºC.

For a comparison of the Danger Den’s TDX performance to other waterblocks tested to date, see Overclockers.com Waterblock Test Results.

Danger Den’s TDX Waterblock is a very good choice for CPU cooling, but with moderate flow resistance, the TDX needs a waterpump of something like 300 gph to function effectively. Other components, such as a radiator or GPU block, will add to system resistance, increasing the waterpump requirement.

For users who like to tinker, the accelerator plate design offers a LOT of possibilities for testing various ideas.

Thanks again to Danger Den for sending this our way.
