The Sentry 3 can control a maximum of fifteen fans simultaneously.
The Sentry 3 is the latest touchscreen fan controller from NZXT. The controller features a 5.4-inch screen, which NZXT claims is 33 percent larger than any other fan controller currently avaialble. The fan controller slots into a 5.25-inch drive bay and features an integrated control for adjusting your fan settings on the fly.
The PowerSlide bar allows you to change fan power as well as speed with a single swipe of your finger. The PowerSlide bar also features the ability to daisy chain fan groups, which lets you control settings for multiple fans simultaneously. You can also configure a quite mode that automatically powers down all fans to an inaudible level and a gaming mode that runs all fans at maximum speeds.
The Sentry 3 comes with five fan channels, in which each channel can control three fans thanks to 15 watts output. NZXT mentions that the Sentry 3 works with any 3-pin or 4-pin PWM fan on the market, also stating that it is the only such product in the market other than the Sentry Mix 2 that offers integrated overvolt, undervolt, and short protection.
NZXT is selling the Sentry 3 for $34.99 from the NZXT Armoury Store and other etailers.
