How to install the fan using the anti-vibration mounts?

NA-AV1 and NA-AV4 anti-vibration mounts

With single sided anti-vibration mounts, such as the NA-AV1 and NA-AV4 mounts, first pull them through the mounting holes of the case. Then put the fan onto the anti-vibration mounts and pull them through the mounting holes of the fan, as seen in the picture below.

Diagram showing how to install a fan using anti-vibration mounts. The fan is attached to a case panel via rubber mounts inserted through the mounting holes. Close-up insets illustrate how the mounts are pulled through the panel first and then secured to the fan.

NA-AV2 and NA-AV3 anti-vibration mounts

With double-sided anti-vibration mounts, such as the NA-AV2 and NA-AV3 mounts, first pull them through the mounting holes of the fan and then push them through the mounting holes of the case.
