A quote from the article:
>> NZXT Sentry 2 Fan Controller Review
NZXT isn't quite known for their fan controllers, but you may have come across their original Sentry fan controller. NZXT has now released an updated, full color, touch screen Sentry 2 to blow its predecessor out of the water. The NZXT Sentry 2 supports up to five fans and five temperature readouts in only a single 5.25" drive bay. Some fan controllers support only 3 pin or only 4 pin connectors, but the Sentry 2 supports both! Read on further to see what else it has in store.
