Know before you buy
Yes, the MULTIFAN S7 uses a standard USB plug, making it compatible with the USB ports found on most modern gaming consoles, receivers, and DVRs.
The system is designed for quiet operation, producing a maximum noise level of 19 dBA. This is whisper-quiet and generally imperceptible in a typical living room or home office environment.
Not necessarily. The fans can be placed on top, behind, or beside your equipment. Because they can be laid flat or stood upright, you can position them to pull heat away from vents or push cool air into your cabinet.
The unit includes an integrated multi-speed controller on the power cord. This allows you to manually toggle between different speeds to find the right balance between cooling performance and noise levels for your specific setup.
These fans are built with dual-ball bearings, which are rated for a 67,000-hour lifespan. This design is specifically chosen for long-term reliability in environments where the fans may run continuously.
