If you are looking for some silent performance cooling, you have no doubt come across the DangerDen website, and seen its extensive list of watercooling products. Catering to intermediates all the way to those who consider themselves extreme, DangerDen offers a kit that will suit your every need. The company was kind enough to send over their MaximumCPU kit for review, giving us at OCC a unique opportunity to look at high grade liquid cooling. Being the leader when it comes to liquid cooling, this performance kit is sure not to disappoint.

Closer Look

Coming home to see a small, plain brown box sitting on my step left me a little skeptical as to its contents. After opening it up, I was excited to see the DangerDen MaximumCPU kit! Unloading all the goodies onto my table, I was surprised to see a liter of coolant (or mix) shipped with this kit.

The kits ships with the TDX water block, which comes with a copper base plate and Lucite (acrylic/plexiglas) top, along with stainless steel hose barbs.

In addition to the TDX, the kit comes with one of the slim line Maze4 GPU blocks. This also consists of a copper base plate and 2 stainless steel hose barbs, but this time with a black plastic top.

Besides the blocks, the kit comes with a single fan, high flow radiator that can mount either one or two 120mm fans (one included (papst)).

You can’t have liquid cooling without a pump, and what a beast of a pump this kit ships with! This baby is fairly large (about 4-5” tall) and has a steel mounting plate, along with 2 molded plastic hose barbs. This pump is designed to run off your computer power supply, so it comes equipped with a Molex connector.

For storing your coolant of choice, this kit comes packaged with a Plexiglas reservoir that will conveniently fit into a spare 5.25” bay in your computer.

Now the one thing that this kit has that most others lack is prepackaged coolant (or mix). This comes in the form of a 1 liter container and mixing instructions.


Let me say that this will not be a tutorial on installing the kit, as it was quite easy. Simply unmount your old cooling system, and then use the supplied screws, spacers, and nuts to tighten down your new waterblocks. First things first with a new watercooling setup, I measured all the lengths of hose (after a dry mount), and plumbed the kit outside of the case. Plumbing was a breeze as you simply slide the hose over the barb and use one of the push-ties to hold it in place.

Next step was to fill the system and leave it running for a day to check for leaks. Once I was sure that there were no leaks, I powered down the system, drained it, and proceeded to install it into my computer. First comes the CPU, which requires you to remove the stock cooling from your processor. My style of motherboard has a screw on either side of the CPU to fasten down the cooler. Remove the top mounting plate, but leave the back plate as the TDX utilizes the stock backplate. Use the supplied hardware to fasten the CPU block, which is secured using 2 threaded rods, nylon washers, and some springs. Tighten down the block until you feel that it is snug. Don’t be worried about damage as the CPU can take a lot of clamping force. Plus, it needs to be tight for the best heat transfer.

Next up was GPU, which was simply removing the old cooler and fastening on the new cooler. The Maze4 came with 2 different back plates for different styles of cards. It uses the same mounting method as the CPU block does. Thread the rods through the card/mobo into the block, and with a spring and nut on the other end, tighten till snug.

After that, it was time to mount the reservoir, which is a Lexan box. It simply slides into a spare 5.25” bay. The radiator, which can either be mounted to the case (with supplied hardware) or it can sit on the desk outside of the case. Last but not least is the pump. This baby comes with a mounting plate, but I chose to use a piece of double sided tape to secure the pump to the bottom of my case. After refilling, I was ready to try this baby out!



Testing Setup For testing this beast of a watercooling setup, I will be using the same tests that we used in the Asetek Waterchill Extreme Water Cooling Kit, which had the CPU running at stock (2.2Ghz) as well as overclocked to 2.9Ghz. For idle temperatures, I booted the machine and let idle for 25 minutes. For load, I opened up a copy of Prime95 and let that run for 30 minutes. For the GPU, we are also running stock and overclocked. The temperatures were gathered by booting the machine and letting it idle at the Windows desktop for 25 minutes. For load, 3dMark03 was looped twice. Now on to the results!

** STOCK HSF was not Stable As we can see from the temperatures listed above, this new DangerDen kit really pulls its weight! It came within a few *C of the Aestek kit at stock, but really started to shine with higher heat outputs. As an experiment, I was able to get the 3700+ up to 3Ghz @ 1.7Vcore with a load temp of 36*C, much further than I have ever accomplished before.


The solid numbers we gathered from this DangerDen kit, as well as the ease of installation, leaves us with a superb respect for DangerDen. Not only does this kit cool like no other, but it is nearly silent as well. With this amount of cooling at your disposal, you could cool a lot more than a single CPU and GPU in the loop. Having a solid feel, as well as a simple and effective way for securing the hose, left me feeling that I was safe from leaks. Overall, this is a very high performance kit. If you have the money and are looking for some of the best liquid cooling available, then this is the kit for you.
