In order to install the Sentry Mix, you need to open a 5.25” bay on your case, put the panel in place, attach the screws, and make the connections.
There are two standard peripheral power connectors for the power supply connection. They are joined in a single power cable before reaching the controller, so you will not need to connect both of them, unless the total power of the fans you are controlling is too much for a single power supply output.
The fans must be connected to the output wires with three-pin connectors. It means the Sentry Mix is not compatible with PWM fans nor with fans that use a standard peripheral power connector (“Molex”) unless you use an adapter (not included).
All the fan cables have only two wires, which means the controller doesn’t receive the rpm signal.
