These Nexus ultra-soft silicon fan gaskets are designed to reduce the vibration from PC case fans and maintain a seal between the case side and the fan housing.
A case fan in contact with the PC housing can cause vibration during operation. By placing a SA-Series noise absorber between the case and case fan you eliminate any direct contact between the two, this way there is less vibration and noise.
These Nexus silicon case fan noise absorbers are made from the best possible silicon to guarantee effectiveness and durability. The Nexus SA-120 absorbs the vibration that otherwise would be transmitted from the fan into the case chassis and case housing. The material is ultra effective and easy to install.
