1. Anodized black CNC machining, standard dual fan design, perfect for RTX 3090 3080 3070 Series graphics card radiator. 2. Good compatibility, the thickness of the radiator body is 15 mm. 3. High performance adjustable speed fan: Standard dual 6010 fans, up to 20CFM in full load, low noise hydraulic bearings, PWM speed control possible, both dynamic and static. 4. Intergation backlane radiator, standard 2 fans design, no need to piece together, easy to install. 5. PS: The actual installation needs to be equipped with a thermal pad. It is directly in contact with the metal backplate and cannot conduct sufficient heat. The actual installation height is 15mm of the heat sink + the thickness of the thermal pad.
