Motherboards offer us a limited number of fan headers, and generally these have a low wattage draw. So what are we enthusiasts to do with all the fans we tend to put in our rigs to keep them cool? Well, should we still have more fans left over to power after using up the motherboard's fan headers, we can do one of two things: to plug them into a molex connecter and run them at 100% speed, or turn to a fan controller. Which brings us to the subject of today's review, the NZXT Sentry 3 fan controller. The Sentry 3 joins NZXT's lineup of five other fan controllers. With a MSRP of $34.99, this is a budget minded controller. Is it worth the price? Follow along and find out.
