Ideal for placing cooling fans underneath A/V receivers, DVRs, video game consoles, stereo equipment, routers, switches, set-top-boxes or other devices that have ventilation holes at the bottom side Gaps between the pads and offset design enable the fan to draw in more air from the sides, thereby ensuring optimal ventilation performance Multiple fans equipped with NV-MPP1 pads can be combined to support larger devices (e.g. 4 sets/fans for stereo amplifiers) and provide maximum cooling from underneath Compatible with most Noctua 12cm & 14cm fans (e.g. NF-A12x25, NF-F12, NF-S12A, NF-A14 series, including 5V PWM models with USB power adaptor), NA-FG1 fan grills can be added for protection Anti-vibration design: Made from silicone rubber, the pads efficiently prevent vibrations from being transmitted
