“Push” and “Pull” Defined
Many users ask about the terms “push” and “pull”. This simply refers to a fan push-
ing air into the radiator or the fan pulling air through the radiator. The stock single
fan configuration is a push setup with the single fan pushing cool air from outside
the case into the radiator.
Adding a second fan, as seen below, results in the second fan pulling the air
through the radiator. A push-pull set up bringing cool air into the radiator with 2
fans is an excellent set up for cooling your CPU. Ideally, you will need to use 2
identical fans to avoid any of the airflow issues that can arise with using 2 fans
that have different airflow characteristics.
Most fans have directional arrows indicating fan blade rotation and airflow direc-
tion as circled below. Note that the “pull” fan on the right has been modified. A
corner of the shroud has been cut away to clear a heat sink on the motherboard.
This is a common solution to clearance issues.
