Water-cooling for Everyone 3: Swiftech H20-120 Rev. 3 and Thermaltake Bigwater (cont.)Thermaltake Bigwater Description: Thermaltake is highly known for their super stylish computer cases and CPU heatsink coolers. To keep with their reputation, the Bigwater is also a stylish water-cooling kit. Starting off, the Bigwater uses a rectangular pump/reservoir combo unit that has an internal blue LED. The overall dimension of the unit is pretty compact allowing it to fit in just about any tower case.
There are four hose connect headers on the side of the pump. The bottom two headers are equipped to easy hose connectors. These two connectors are the standard pump inlet and outlet. The top two hose headers allow the pump to be connected to the included Refill Water Tank, which can be used to fill the Bigwater kit and can also function as a backup reservoir. While it is a nice thing to have, it is purely optional since the top of the pump does have a fill hole.
The pump receives power through a 3-pin plug that can be plugged into a motherboard's 3-pin fan header. Pushing 120 liters per hour with a noise output of 20dBA, this is an extremely quiet albeit not very powerful pump.
The Bigwater uses a very well built waterblock. Bigwater's waterblock features a thick copper base with an equally thick acrylic top. The base has a very decent lap job. Oddly enough, the raised surroundings have a better shine.
Embedded in one of the corners of the acrylic top is a blue LED. Bigwater's waterblock uses the same easy hose connectors as found on the pump. The internal design of the waterblock is rather unique. It uses a zig-zaging pipe style flow channel. All the other rectangular waterblocks I have seen use the numerous straight fin design. At 453g, this is the heaviest waterblock I have encountered; outweighing even a lot of fan/heatsink coolers.
The final main component of the Bigwater is the 120mm radiator. The radiator has the traditional design of round copper pipes going through aluminum fins. It is enclosed in a metal black housing which gives the radiator a solid look and also protects the delicate aluminum fins. The radiator also uses the easy hose connectors.
Attached to one side of the radiator is a grilled variable speed 120mm fan. The fan is Molex powered with an expansion slot speed controller. The other side of the radiator has mounting holes that allows the radiator to be installed on a case that has mounting holes for a 120mm fan. On top of the radiator is a long tab with a slot that allows the radiator to be mounted externally on a case that does not have a 120mm fan accommodation.
Other things included with the Bigwater are UV reactive green tubing to connect everything together and a big bottle of green coolant. Also, included is a set of H shaped mounting brackets which features enough holes to support Socket 478, LGA775, 754, 940, and 939. For Socket A users, a K7 clip is included. Rounding out the package is a small pouch of thermal compound and an expansion slot cover that has cutouts to allow tubing and wires to pass through.
