Test Results

Ambient temp = 22°C


These tests do well to empirically verify the claim made in the introduction. The difference in performance between these quality water blocks is exiguous, all things being equal. There are, however; other factors to consider such as using the accelerator nozzle-1 with the TDX, and the pressure of the Hydor L-30. If either block has the advantage in a low flow rate environment, it seems Cool-Cases CF1 benefits most, based on the results of low pressure tests found at Watercoolplanet, and Caseumbau.

In my next water block round-up, I'll be featuring the blocks tested here, along with Danger Den's RBX, and Cool-Cases CC-Magic silver water block. The test system will use a Danger Den double heater core, and the Hydor L-40, and/or L-45 pumps.

Conclusion.

While I understand Danger Den's re-introduction of their accelerator-nozzle technology, I wonder if they could have built even a better performer. Perhaps eschewing the accelerator-nozzle inlet, for mini-jet's either recessed or located just above their "heat voids"(isolation cups)? While the difference among nozzles does give the end-user a malleable (#3) water block, there may be a trade-off in performance. After all, trying to be all things to all people often involves trade off's. In all fairness the same might be said of the CF-1, which has made a major improvement in its new flow section, yet still utilizes its original base plate.

The redundancy of two recessed areas on both sides of the impingement zone is perplexing. Perhaps this makes the block idiot proof to mount, however; the positioning of the inlet directly above the impingement area, and the outlet which can only benefit from one of the recesses, makes the second a deficit. I believe water may gather and stagnate in the unused well, adversely effecting flow (pressure), and/or raise water temps. Fortunately Cool-Cases have released a new base plate. With the new CCR01-03 (upgrade bodenplatte), original CF-1 owners have two items to purchase for optimal performance. Pictured below [left], the original CF-1 base plate, the new design [right], utilizes just one of these recessed area's, as pragmatism prevails. The new base-plate's impingement zone features intersecting channels rather then pins. The channels are beveled, creating square extrusions for heat conduction. The varying depth and direction of the new channels concentrates water flow down to the primary impingement area, and then acts as conduit directing the heated water to the outlet.




Not withstanding the deficit in the original CF-1 base plate above, my recommendation is those whom are able to purchase the Cool-Cases CF-1 Rev.2, should do so. In addition to its excellent performance, I favor the block's ease of use and ergonomics. Although switching in the Rev.2 flow section does require disassembly, switching from Socket-754 to Socket-478 only requires replacing mounting hardware.

The TDX, however; requires disassembly anytime a socket change, or accelerator nozzle change is needed. I recently stripped one of the bolts on my RBX. I felt the steel bolt, and/or Allen wrench included was inadequate for the pressure required to remove the factory installed bolt.

Where ergonomics are concerned, you can place LED's into the CF-1 Rev.2 which make's an attractive option for windowed cases. It can be purchased at Watercooling.de

Unfortunately for USA reader's acquiring Cool-Cases' water blocks will be difficult. Luckily for us Danger Den has done very well with its TDX. I prefer this block over the RBX based on performance, and simplicity. Its twin barb design and svelte size make a desirable block. In addition the silver version is an enticing option if you have the cash. Contact Danger-Den for availability and pricing.

I'd like to thank Florian, and Dano for their help, and Hydor for the pumps.
