120mm quiet housing cooling fan with PWM speed control and vibration dampening grips.

In the name of cooling, the G2 marking indicates that it is second generation, i.e. an improved version of the NF-A12x25 with a unique blade and frame design, and an energy-efficient etaPERF motor. The Sx2-PP designation indicates that there are 2 NF-A12x25 G2 fans in the kit, but the speed of the PPA designation is ~50 RPM lower, and the PPB designation is ~50 RPM higher. This design has a double purpose: on the one hand, it reduces the generated vibration and the generated noise (less disturbing for the ear).

In addition to cooling the housing, water cooling is also suitable for cooling radiators and CPU cooling fins.
