NZXT Unveils Sentry LX High-Performance Fan Controller

ya the case this was shown with was blah but the controller itself looks pretty nice, wonder how well it will really perform.

What is the limit in watts for each fan that you can use?

I have some really quiet 6 watt fans that would be even quieter if speed controlled, they aren't in my PC at the moment because they draw too much for the motherboard fan headers.
