Love comes in small bundles they say and it must be true. I was ever so happy to receive a nice package from the U.S.A, living in The Netherlands I immediately knew it was from Danger Den. Who else would send me mail from the other side of the world? As you might have noticed I reviewed the Danger Den Maze 4 GPU first because I had some motherboard and CPU problems, but now that that is all fixed I can test this quality waterblock from Danger Den.
So what do you get when ordering one of these blocks? Obviously the block itself and a Ziploc bag with the necessary mounting tools, you know your nylon washers, springs, and other hardware.
First thing that I noticed is that its smaller then other blocks, like the Danger Den Maze 4 for example. This block totally concentrates on cooling the core, quite obvious since it’s the part that expels heat but will its size matter? As usual Danger Den engraved there company name and the type in the block, in this case “Danger Den TDX”.
When checking the site I found out that the base is machine lapped with 1200 grit sandpaper, which makes it nice and smooth. The base has a little protective film to prevent it from being scratched and protect against corrosion. When removing the film you are left with an oily residue, just use some white spirit or alcohol to remove it.
It might just be me, but when I have something new it has to come apart so I can see how it works. I removed the top to have a closer look in the block without the hose barbs restricting view.
First thing you may notice is the nozzle, yes that’s right the block uses accelerator nozzles. Think of them like your adjustable showerhead, giving you the ability to direct the flow of water. Danger Den sells an optional package of 5 different designs of nozzles that might help you to just shave top of that last degree for those crucial few MHz on your overclock. The TDX comes stock with nozzle #1 so if you want to do any fine tuning you will need to buy the extra nozzles.
The nozzles are great but underneath that nozzle is what really counts. Instead of using their traditional maze flow design Danger Den has made something completely different. The TDX is similar to the RBX block from Danger Den, although modified for use with only 2 hose barbs. The area of water impingement features a wave shaped set of channels with cupping divots that force water to convect with the surface via cavitations of the blocks surface right over the CPU. This design greatly increases surface area at the waters impingement, as well as increasing heat transfer by using higher pressure forced convection.
