And here is what the system achieved in our tests:

The results of the ordinary Bigwater are given for comparison. The expansion tank surely brings in some gains: there is almost no difference in the Idle mode, but the updated system looks considerably better under load. This is an expectable outcome as the performance of a liquid-cooling system depends on the amount of coolant and the new Bigwater can take in almost three times more of it.

The pump left me with rather mixed feelings (by the way, the same is true for the Tribe and the Symphony kits, reviewed below, as they use exactly the same pump). It has become smaller and, according to the manufacturer, more efficient, but it produces a noticeable vibration and a characteristic “babbling” sound. It means the user has to carefully choose the place of the pump in the system case. The babbling is only audible in complete silence when the PC case is closed, but the vibration is harder to deal with and the solution will depend on the specifics of your particular system case. Well, if you don’t strive to make your computer absolutely silent, you may not bother about the pump at all.

The fan and the radiator have not changed since our previous review, so their noise is exactly the same.

Highs: Easy to assemble and fill; New pump; Good performance; Appealing price

Lows: No labels on the pump’s fittings; You have to bother about finding the right place for the pump

Conclusion: Users who are looking for an inexpensive liquid-cooling solution are going to like this update, especially since it is also accompanied with a price reduction.

Average price: $90
