Thermaltake ToughFan 12 Pro 120mm 25mm 2-pack CL-F159-PL12BL-A

120 mm high-static-pressure fan pair

This twin-pack delivers two 120 mm PWM case fans rated for 500 to 2000 rpm and 70.8 CFM airflow. The hydraulic-bearing Gen.2 design keeps noise at 22.6 dB-A under load. Builders fitting radiators or restrictive chassis gain the static pressure needed for dense fin stacks.

Anti-vibration mounts and LCP blades

Each fan includes rubberised anti-vibration mounts that decouple the frame from the case, reducing transmitted hum. The nine Liquid Crystal Polymer blades are extended and widened, while extreme-tight tip clearance cuts leakage. A metal-reinforced motor hub adds rigidity at full speed.

Check PWM header count and clearance

Verify your motherboard has enough 4-pin PWM headers for both fans or plan a splitter. Confirm 25 mm thickness fits your radiator or chassis mounting points without fouling cables or side panels. The low-noise curve drops to 500–1500 rpm and 18.3 dB-A if quieter operation is preferred.
