NZXT Sentry Mesh Fan Controller
Sep 27th, 2012 | By NivedhInstallation is as easy as sliding the Sentry Mesh into a free 5.25″ bay in your case and plugging in the fans and the 4-pin connector to your power supply. Once powered up, the small LED under the NZXT logo lights up.
The stealthy looks of the Sentry Mesh allow it to blend in well.

The sliders are very intuitive to use. One thing I was disappointed in was the fact that the minimum setting corresponds to 40% fan speed. The maximum setting is 100%, as expected. I would have liked to see an option to turn fans off completely, if desired. However, the unit does the job and does indeed allow adjustment of fan speed between 40 and 100%.
