This time we tested Sentry 2 fan controller from NZXT, which uses only one 5 ¼" bay from your case and has an LCD touchscreen. Check out this product features in this review.
Sentry 2 box is very small and shows only a picture from the controller screen besides giving the information of the number of temperature sensors (five) and controlled fan outputs (also five). Just as Touch-2000 controller we tested a few days ago it has no buttons, all adjustments are done directly on the touchscreen.
Is also has an audible alarm that sounds if one of the sensors measures temperature above the programmed limit or if one of the fans become disconnected or stops working. But we found that this product has the exact same problem from its competitor: the alarm sounds in low volume and only for a few seconds. So you will be warned only if you are in front of the computer when the problem happens.
