When we power up the PC with the Sentry 2 installed, we really get to see where it shines. The touchscreen display is sharp and colorful, while not overly bright like a lot of lit accessories. It really draws the eye, and the button-less face really does look sleek, despite not being brushed aluminum like it's predecessors. I found the controls fairly intuitive, which is good considering the lack of instructions. The animated fan is also the button to switch between which fan you want to check temps/adjust. Touching the +/- signs adjust the speeds up/down of course, and touching the word "auto" switches between automatic and manual fan control. Touching the temperature readout opens the alarm adjustment option, where you can program the temperature at which you want to be alerted of hazardous heat levels for each fan/probe. The only complaint I have here is that I cannot, for the life of me, figure out how to change from Celsius to Fahrenheit. I am also curious as to the meanings of the "circled R" and "power" symbol on the far right of the display. Detailed instructions would have helped.
The functionality of the NZXT Sentry 2 is undeniable. The touchscreen controls are quick and accurate, and having five temperature probes at your disposal is a handy tool for the overclocker with degrees on his/her mind. The downside to having all these probes and independent fan speed controls is the wiring. You would have to be a case-mod wizard to hide all of these effectively.
Overall, the Sentry 2 earns praise for it's eye catching sleek form and display, and high marks for making itself an essential part of any serious overclocker's rig. The instructions could have been a page or two deeper, but the praise far outweighs the criticism here; the NZXT Sentry 2 earns it's weight in gold!
