Accessing the liquid coolant was not possible with the sample we received.
The quality level off all components used did not give us any reasons for complaint; even the sealing of the coolant circuit looks robust. The large fan uses the 3-pin rather than the new 4-pin connector. This is no disadvantage, since readjusting the fan speed is automatically done by the cooling system rather than the motherboard.
For tests, we used the 3.6 GHz Pentium 4 560 and ran Prime95 for approximately two hours. At this workload, the heat dissipation is around 98 W. With the Sanyo Denki device, we achieved CPU temperatures of around 65°-66°C, while air coolers do not manage to keep the processor below 75°C.
