Corsair has not deviated from its playbook and used the same formula that was successful with the earlier Hydro Series coolers, the H50 and H70. The H80 is an upgrade from the recently released H60, with a larger radiator that is not quite twice as thick as the one used on the H60, but comes in at 38mm thick with total dimensions of 152x120x38mm. Connecting the radiator to the pump assembly are a pair of FEP (Fluorinated Ethylene Propylene) tubes that are used to minimize evaporation of the coolant mixture. The radiator is made from aluminum while the coldplate is copper, giving you two dissimilar metals in a system.
