The thickness is only 20mm. _x000D_ It adopts a more efficient bionic airfoil design with 13 fan blades. Compared with the same specifications, under the conditions of the same wind pressure and air volume, it can achieve greater air volume and lower noise at low speed. _x000D_ The power supply part supports two interfaces: small 4PIN and large 4PIN, which can be connected to the small 4PIN interface of the motherboard or the large power supply interface. _x000D_ It can also be used to replace the 12cm CPU cooler fan, so that the CPU cooler has lower noise and stronger cooling effect. _x000D_ _x000D_ Specification: _x000D_ Speed: 1,000 RPM _x000D_ Air volume: 36CFM _x000D_ Noise: 21.44dBA _x000D_ Power supply interface: 1*3Pin, 1*4Pin _x000D_ Material: ABS _x000D_ Color: black and white _x000D_ Size: 120x120x20mm/4.72x4.72x0.79" _x000D_ _x000D_ Note: _x000D_ 1.
