The NV-MPP1 Sx4 is a set of four NV-MPP1 multi-purpose anti-vibration pads for Noctua 120x25mm and 140x25mm fans (see fan compatibility). When installed in the “stand” position, they are a great, simple solution for putting a fan on any level surface to have it blowing sideways, e.g. in order to provide extra airflow on a desk or towards devices that have ventilation holes on the sides. Installed on the intake side of the fan, the pads can also be utilised to put a fan underneath small devices such as switches, routers or set-top-boxes that have ventilation holes at the bottom side, blowing cool air into the device. This way, the pads can also be used to put fans on top of A/V receivers or other devices that have ventilation holes on top in order to help exhaust hot air. Last but not least, the pads can be installed on the outlet side of the fan in order to position it blowing cool air down onto devices that can benefit from extra airflow from above. In either of these configurations, the NV-MPP1’s soft, heat-proof silicone rubber will efficiently prevent any transmission of vibrations. Thanks to the integrated mounting pins, fixing the pads to compatible Noctua fans is a breeze. Optional NA-FG1 fan grills can be installed if required.
