The Sentry 2 is a 5.25” device that can be installed in a drive bay of same size. The Sentry 2 uses only one slot, like a typical DVD drive. Two screws are enough to secure the device, but all four could be used for added security. The manual included with the Sentry 2 briefly explains how this may be done.


The Sentry 2 installed and powered

Needless to say that, after you secure the device, you must plug the Sentry 2 to a molex power connector of your power supply. Once that is done, you proceed with connecting your fans to the fan cables of the Sentry 2, then route the temperature diodes to the fan with the matching number. Once all of that is done, it is time to power on the system and observe the Sentry 2’s colourful screen, which becomes functional after a few seconds. Given the fact that the Sentry 2 has many cables, it is highly recommended that you plan ahead on how each of the cables will be routed inside the computer case. Indeed, if you are planning on using five fans with the Sentry with temperature diodes, you will have a total of 11 cables (including the device power cable) to organise. Without a plan, you might end up with a disorganized cable arrangement in your computer case, which is not ideal for aesthetics and, of course, airflow!
