Although the Corsair H80i comes with two 120 mm fans, it uses a regular 120 mm radiator and not a 240 mm one. In other words, the radiator is “sandwiched” between the two 120 mm fans. The sealed radiator-block system is shown in Figure 3. At the left is the 120 mm radiator; at the right is the block.
Figures 4 and 5 reveal the 120 mm radiator of the Corsair H80i.
