The Antec Kühler H2O 920
Figures 3 and 4 reveal the radiator, which has the purpose of transferring the heat from the coolant liquid to the air passing through it. The hoses that connect the radiator to the block are very flexible, allowing easy installation.
Figures 5 and 6 present the block, which performs the task of transferring the heat from the CPU to the circulating liquid. The pump is integrated in the block. The copper base comes with pre-applied thermal compound.
Figure 7 shows the cables that come off the block. The left one must be connected to the motherboard in order to power up the product. The middle ones are for connecting the fans, and the right connector goes on a USB header of the motherboard.
The 120 mm fans are shown in Figure 8. They have four pin connectors, which means they are compatible with PWM speed control.
