3RSystem Poseidon WCL-03-120.cu

The second Poseidon system to be tested resembles CoolerMaster’s Aquagate mini R120 kit. Well, considering at what time they were developed, it would be more correct to say that the CoolerMaster is like the Poseidon. The system comes filled already.

The cooler-resembling pump is combined with the water-block as a single unit. The water-block’s fastenings are not designed well.

A miniature reservoir is glued to the radiator:

This system performs about 1-2°C better the WCL-02 and its noise is still at a rather low level. We should confess it was a problem to get the system going: the pump motor was rotating, but the water wouldn’t circulate. The pump only began to work normally after we had repeatedly pumped and blew it through. After the air bubble was driven out, the performance of the pump was 43 liters per hour.

Summary: This is a primitive and out-dated system that has no chance against modern kits. You will hardly want to part with $80 to get it.
