Water-cooling for Everyone 3: Swiftech H20-120 Rev. 3 and Thermaltake Bigwater (cont.)Maintenance: Both of these water-cooling kits use coolant that makes it unnecessary to periodically drain and refill the system. However, you should check the coolant level in the reservoir from time to time. As the H20-120's guide mentions, evaporation in a closed circuit is extremely limited, but is still present due to the permeability in the vinyl lines (tubes). In addition, it is important to check the coolant level because if a leak develops anywhere in the circuit, the level would have a noticeable drop. In addition to observing the coolant level, you should also periodically dust off the radiator to maintain maximum cooling efficiency. Expandability:
One great aspect about water-cooling kits is the ability to expand them. One of the most common ways to expand a water-cooling kit is to expand their "usefulness" by adding a VGA waterblock so that the kit also cools the GPU. Both Swiftech and Thermaltake offer VGA waterblocks for their respective kits. In addition, Swiftech also offers a chipset waterblock so the Northbridge can be water-cooled.
Another way to expand a water-cooling kit is to expand its cooling efficiency by adding a secondary radiator. Both companies offer their respective radiators as individual upgrade components. In addition to the usual upgrade components (VGA block, radiator, ...) Thermaltake also offers some other unique and informational upgrade components, such as a digital water temperature indicator, water level indicator, and water flow indicator. While Thermaltake offers unique upgrades, Swiftech offers practical upgrades such as the already mentioned and highly recommended Radbox. Because it uses the very common 1/2" OD and 3/8" ID tubing, the H20-120 is compatible with water-cooling components from other highly regarded water-cooling companies such as Asetek. This means, if you would like to use the Asetek Antarctica with the H20-120 Rev. 3 kit, you can. Conclusion: Performance wise, this is the best Water-cooling for Everyone yet. At high fan speeds, both the Bigwater and H20-120 have excellent cooling performance. But one of the main incentives of switching to water-cooling is to cut down on computer noise and that is done by slowing the fan down. This is why, in my opinion, low fan speed performance is the true indication of a water-cooling system's performance. At its lowest fan speed setting, the Bigwater showed a considerable increase in temperatures. In contrast, when the H20-120's fan speed was cut down, its cooling performance took only a minor hit. We are still at a point where there is a considerable price gap between a top tier CPU heatsink and a recommendable water-cooling system, but just like everything else, there is a price to pay for luxury. For those on a budget that want a water-cooling kit that performs, the Thermaltake Bigwater is a great choice. For those whose budget is more expandable and want something with superb cooling, the Swiftech H20-120 Rev. 3 is for you. Thermaltake Bigwater:
