Comparison of coolers using heatpipes
Poseidon WCL-02 (или Iceberg 1)
We have tested Poseidon water cooling system, made by Korean company 3RSystem. Besides that, this system is being sold under Iceberg 1 trademark (however, reverse situation is possible). This product appeared on Russian market in the beginning of 2002 and has conquered an empty market segment of high performance cooling systems.
Of course at that moment many enthusiasts used self-made water cooling systems. But an ordinary user could only dream about quiet and at the same time effective heat conduction.
The system is supplied in a big cardboard box, all its components are packed thoroughly.
I have to tell particularly about the user manual, which describes installation procedure in detail. However, we won't consider this question circumstantially because this product has already virtually disappeared from sale. The reason is too high price, at the moment of its uprise Poseidon WCL-02 costed more than $100 (with a prime cost of approximately $20-$30). For this quantity of money a user was buying aluminum waterbock, aluminum heatsink and fan, liquid reservoir and pump and a connection tube.
Just a half a year after that more effective systems with brass heatsinks and waterblocks started to appear at the same price. As the result they displaced Poseidon WCL-02 from the market.
An assembled system looks in the following fashion:
Surely, after the system is assembled it must work for some time outside a computer. After the complete testing on possible leaks it is possible to install the system into the computer.
As you can see, the system occupies very little room and can be easily placed into a standard ATX case.
I should say a couple of words about the waterblock: the quality of treatment was horrible. Everything you can see on the photograph below is the result of 15 minutes of polishing.
The waterblock has two kinds of bracings: a metal clip for AMD processors and a plastic cup for Intel processors. Everything is very clear with the clip (it consists of two parts), but installation is very difficult for Intel processors. So the waterblock is installed into plastic cup, which must be pinned by a plastic frame of a "box" processor (this is the only detail, which is not contained by the package). As the result, design looks very uncomfortable from assembler's point of view: as a rule a half of attempts fail and the plastic frame breaks.
And now a few words about the system in general. In spite of many insignificant drawbacks elicited at assembly process, the system works rather quietly. The only source of noise is an 80mm fan, which has a standard bracing. This bracing allows to replace it with a more quiet one. The pump works without noise.
A couple of words about the performance. I installed Poseidon system onto AMD platform and it has shown bad quality of cooling. For comprehension I will refer to the result of our old review:
The reason of poor effectiveness lies in the fact that AMD processor kernels contact aluminum waterblock directly. This leads to poor heat conduction at high charge, aluminum cannot conduct heat fast enough to decrease kernel temperature.
However such problem is partially away with installation of Poseidon WCL-02 on a system with Pentium4 processors, which have built-in heatspreaders (a brass plate). As the result, the area of heat exchange increases and the total effectiveness increases.
As the result, after modification of waterblock bracing,
a part of plastic cup is filed off and other type of bracing is used
Poseidon WCL-02 system was used in the majority of motherboard tests for Intel processors. And for more than 18 months I didn't have any problems with its impermeability or pump operation.
