  • This product was designed for use with the fan on and passed engineering tests with the fan on. We have added a fan switch that can turn off the fan when a low-noise environment is needed. However, the device should only be used for short periods of time with the fan in the OFF position as prolonged use may cause the device to overheat and this may cause damage to the system, cause issues to data integrity, reduce system reliability and/or shorten the lifespan of the electrical components. For best results, we recommend that the device not be used continuously for more than one hour with the fan in the OFF position.
