Detailed Craftsmanship Pushes Through LimitsAfter numerous research, tests, and modifications, we finally tuned our CT series fan blades to meet our expectations and beyond their limits. These seven fan blade structured fans can provide a 2.23 mm-H2O air pressure and an airflow of 57.05 CFM while maintaining its noise level at 25.8 db-A, allowing you to enjoy these well-balanced performance fans under a friendly budget.Less Cable, More FriendlyThe new cable-integrated daisy-chain design allows the fans to be directly connected, so it minimizes demands of 4-pin PWM ports on your motherboard and shortens the cable length between the fans. We've also included two 900mm PWM cables for you to easily manage your cables while assembling your build.Solid Structure for Better PerformanceThe new CT Series fan frames are crafted to be steady and robust so the fan won't deform easily. We have also modified the exterior design to allow the fans to fit the chassis or radiator even better, so there won't be gaps for air to slip through.A little Surprise for Extra SecurityCT Series Fans are equipped with four round undetachable anti-vibration rubber pads on each of the fan's corners. They are designed to be stable and dampen the fan's vibration, allowing the fans to spin at a higher speed under certain noise levels.
