Sure, I can clarify that for you. The question is about whether a static pressure fan should be used to push air into the radiator or if an air flow fan would be more appropriate. Fans from Corsair, such as AFs and SP models, are what you're asking about.
Pull or exhaust fans don't require a high static pressure spec. But when a pull fan is placed inside a radiator, you're pushing air from outside through the radiator into the case. Unless other case fans are set up for negative pressure with more exhaust than intake, these fans should still have a high static pressure rating to help maintain the pressure difference needed.
Pull or exhaust fans don’t require a high static pressure spec. But when a pull fan is on a radiator, you’re still trying to push air from outside into the case. Unless other case fans are set up for negative pressure with more exhaust than intake, those fans should still have a high static pressure rating to help move extra air in a pressure difference system. If they were on the pull side in an exhaust setup drawing air out, that requirement disappears—those fans only need high CFM/volume rather than high static pressure since there’s little resistance to the airflow.
SO if it's in an exhaust setup, then just the fans moving through the radiator really need to be HSP fans, unless you have a push-pull arrangement. If you only have fans on one side and they're pushing outwards, it's less critical, though having some static pressure capability would still help if there are restrictions like grillwork.
