Zalman CPU cooler Zalman Shark Fin blades Unlike a regular cooling fan, the specially designed Zalman AF120 ring fan with shark fin blade provides minimal airflow resistance, allowing minimal noise during operation. Hydro Bearing, like a ball bearing, has no contact with metal, and a layer of grease replaces the bearing. It produces low noise, low temperature and shock resistance, which is extremely durable and long-lasting. Hydro Bearing, like a ball bearing, has no contact with metal, and a layer of grease replaces the bearing. It produces low noise, low temperature and shock resistance, which is extremely durable and long-lasting. Blade vibration is minimized by preventing the blades from vibrating during fan operation, increasing durability. Wind noise is minimized by suppressing the vortex effect occurring on the blades. Airflow is maximized by minimizing the amount of airflow lost to the outer circumference of the rotor. Addressable RGB lighting top cover Stunning ARGB colors shine through the top cover of the CNPS13X, showcasing your build in the most beautiful light possible with full ARGB customization sync via the 4-pin header. Black coated copper heat pipes The black coating enhances the aesthetics of CNPS 13X Black and improves thermal conductivity and rust resistance. Rubber vibration damper Rubber shock absorbers absorb vibration noise during operation. PWM control for automatic speed control The CNPS13X PWM fan features automatic fan speed control to achieve an optimal balance between cooling performance and noise level. 135 x 79 x 159 mm
