Conclusion

Highs:

First of all, we enjoyed the “thoroughness” of the system. When you buy PC2-C, you get everything necessary to assemble a water-cooled PC: the chassis and full-fledged water cooling solution. The water cooling system includes four water units to cool the hottest spots of the PC.

Secondly, the mounting of the water units and the entire system assembly are very easy. It won’t take too much time to create a complete PC in PC2-C case and, the most important thing is that you are very unlikely to experience any difficulties during system building.

In its “silent” mode, the system produces no loud noises (it will be even quieter, if you replace the 80mm fans with something better), providing excellent cooling at the same time. Overclockers like it, when it is cool and quiet :).

Although there are two pumps in the system, they don’t hum at all. Moreover, such solution provides better reliability: if one pump goes down, the other will continue upholding the system.

One more thing to mention is the light weight of the water cooling system itself. It’s absolutely hermetic, and can be easily transported without unloading the water. By the way, the added ethylene glycol allows using PC2-C in case the environment temperature is about 0^oC or even a little below that and you shouldn’t be afraid that the water freezes up and burst the water units apart :).

Lows:

First of all, there is no power supply unit coming with the system, although there is a chassis. (Koolance modifies third-party chassis and installs its water cooling solution there). Why didn’t they put a quality PSU and set a little higher price?

Second thing to mention is a not very high quality of chipset and graphics chip water units. While the chipset unit copes well with its job, the graphics chip unit won’t handle such monsters as ATI RADEON 9700 or NVIDIA GeForce FX.

The last issue to be discussed here is exactly the case when an advantage may turn into a bottleneck in no time. It is all about the rest of the system components. You see, the CPU, chipset, graphics chip and HDD are now equipped with water units, while the PSU, heatsink and fans are separated from the rest of the chassis in their own special compartment. So, there is no air stirring inside the system case at all. This may lead to overheating of voltage regulators on the mainboard or graphics card (they are usually cooled by the air from neighboring coolers). If you have a CD/DVD-RW, which produces quite a lot of heat at work, the situation may become dangerous. You can install an additional 80mm fan onto the back panel of the chassis to have some airflow in the system case. There is enough room to put this fan on, but PC2-C comes without it. They seem to be really stingy, aren’t they? :(
